Message-ID: Well, here's yet another kinda, sorta, non-robotic subject. But I figure since you guys(gals(PC)) have been ripping up your computers, ya might know how to help me. Today my brother was looking at the back of an old IBM we have. Not so nice with only a 486 and 8megs of RAM. Suddenly he saw a wee little switch hiding in between the power sockets. It said 240v/110v. We have moved here to New Zealand from WA and brought the computer, so it was set to 220v. You might as well guess what he did. He flipped the switch. An appropriate flickering of the lights happened throughout the house. Dead. So. Does anyone know the effects that this would have? I'm guessing that the coils were set to double the voltage already being put out, but also assuming half the input voltage,(for the brief moment it lived for!) so that there was 24v+ 10v+ 0 10v- 24v- instead of the norm. This WAS a 200w power supply. So does this mean just put in a new power supply, or were the boards and hard drive in there fried? (quite idiotic if the thing has absolutely no surge protection, even if it is double the voltage) If so then my heart sinks. I've been working on a PCB full throttle for a day and I was going to have it made this week. Any help as to how to salvage this would be greatly appreciated. Heck, I'll send you a free sample of the PCB if you can help me get the stuff out. There's your motivation. (HC11 board with comms and other accessories.)

Switching power supplies try to regulate the voltage from what the transformer puts out to what the computer needs. Unfortunately, it got twice the voltage it expected, and the circuits that do the switching probably fried. > So does this mean just put in a new power supply, or were the boards and > hard drive in there fried?

Overvoltage and surges are different. A surge is a very short overvoltage situation, and you protect for it differently than a continuous overvoltage. Switching the transformer is not a short overvoltage situation, although in your terms it appeared to quickly die. > If so then my heart > sinks.

Hi, Stephen, I do have a couple of comments. First of all, I applaud your decision to add this to your curriculum and I'm sure the students will find it to be both worthwhile as well as interesting subject. Although I think this might be a point of contention within the DPRG, I also agree with your choice of starting with the BASIC Stamp as the controller. As a former teaching assistant for microprocessor courses, I remember it being very frustrating for both the students and faculty to deal with learning, using and maintaining the development tools that were supposed to make life easier but invariably resulted in a lot of non-valued-added time debugging the tools instead of the project. It's hard for the university to buy and maintain the hardware and software tools, and the students have serious time constraints within which to do the project. The BASIC Stamp is one of the easiest controllers to get up and running on. It is also the controller of choice for things like the US First Competition. So in the context of the material you mentioned I think this is a good way to go. Having said that, as a manager/employer of engineers, I would be concerned if this course (more so if this were only part of a course) was the student's only exposure to (micro)processors. I would expect students planning on working in a number of E.E. disciplines (computer engineering being an obvious one) to have a solid grounding in processor theory and fundamentals such as memory, busses, registers, interrupts, etc. which is hard to get in anything less than a full, dedicated micro-p course. So I think the microcontroller/robotic material you discussed would be an excellent addition to a computer engineering program and a good introduction for other disciplines. I would not, however, want a student to think this was an acceptable substitute for a good processor course(s).

I use one that I got several years ago. It is made for PCBs and the knob on the side moves the table up to the drill bit. I can drill a board quite fast that way. I don't think the ones where you pull the lever to bring the drill down to the work would be as good for this kind of work. Dremel stuff is widely available.

Most PC power supplies are rated 90-132V and 180-264V so you should have left the switch in the 220/240 position for both Western Australia (250V) and New Zealand (220V). I performed this same "Abnormal Operation Test" many times when I was doing UL safety engineering. The good news is that you may have only blown the Slow-Blo fuse in the power supply. The Slow-Blo (Time Delay) fuse allows quite a bit of current for a short time before it blows. It's SPECTACULAR to watch! I doubt that anything damaged your boards. The worst that may happen is that the power supply was damaged, but I doubt it. Make sure you replace the fuse with the exact type and rating! This should be marked adjacent to the fuseholder. It case the fuse is an internally mounted pigtail type, the safety requirements demand that the fuse type and rating be printed on the PCB near the fuse. If the fuse is not accessible externally, PLEASE get someone who knows what he is doing to replace it. There are very dangerous voltages inside power supplies LONG AFTER you turn them off. - -- _ _ / || \ Regards, Alan Bredon / || \ My views & opinions do not represent my employer. /. .||. .\ "PC means Personal Computer, Political Correctness /-|-||||-|-\ is not to be tolerated." _|_|__|_|_ http://www.imagin.net/~abredon/robot.htm | . . . . | And always remember to ESCHEW OBFUSCATION! |__________| ------------------------------ From kevinro at nwlink.com Mon Jun 1 10:57:34 1998 From: kevinro at nwlink.com (Kevin Ross) Date: Thu Feb 15 16:50:50 2007 Subject: DPRG: Robo-Doc.

The idea here is that relatively cheap robots could be deployed in field medic stations, and would be able to operate quickly. Goals being to save the life of the patient without risking the life of the medical staff. They are a very long way from having the ability to write high level control software that might be able to deal with surgery on its own. At current rates of progress in the AI community, it will be an extremely long time before something that complex will be feasible.

Date: Thu Feb 15 16:50:50 2007 Subject: DPRG: Fries. Potatoes or power supply? Message-ID: Sean, I'm glad you asked because there is a lot of misinformation and disinformation surrounding nuclear power. The fuel actually goes into the reactor as 3% enriched Uranium 238. Not really very hot stuff. You can stand next to it and be fine. However, inside the core the neutron bombardment creates every element known to man (including plutonium), but it is shielded from the outside by zircon rods, a steel reactor vessel, a steel lined containment building, and at least 3 feet of reinforced concrete. On top of that, we have redundant systems on top of redundant systems designed to shut the reactor down automatically if any one of a thousand things goes wrong. The real challenge in the nuclear industry is to keep the reactor running (that is, from shutting itself down). It would be impossible to reproduce a Chernoble-type disaster with our reactor design, and very difficult to produce even a Three Mile Island-type disaster, since we learned how to design around that. Regardless, any disaster here would never manifest itself as an explosion. The concentrations of nuclear material required for an explosion are just not present. More likely, a disaster would be in the form of a release of radioactive material, and we have many systems in place to guard against that. So anyway, to answer your question, it does not worry me in the least. Many, many more people have been killed in coal fired plants than in nuclear plants.

Like I said, I initially selected the IVEX package. I like the way you can down load the program and simply pay for more pins. I also wanted a real windows interface (which Eagle didn't have until last year). The first thing I noticed about IVEX is that it crashed the machine when I tried to change color of the background. I called tech support and they said "We haven't tried it with Windows 95 yet" - which was about 1.5 years after Win95 came out! I started getting scared then. They promptly sent a new version which fixed that problem. I still got crashes regularly but don't remember exactly when. I was very disappointed. When the Eagle windows version came out, I got the demo and decided to do it. Since I've been through the whole process - schemo-to-board, I think I made the right decision. Another thing I noticed, Eagle takes out ads in many of the trade publications, IVEX does not.

I have been using the IVEX system for about 1 or 2 months. I am just using their demo version at the moment. It seems to be a fairly decent program. Yes, it does occasionally crash. Unfortunately, I have found that most PCB programs crash on occasion. They are indeed rather complicated to write, and even more difficult to test. It doesn't appear to matter how much the program costs either. Protel98, which costs about $4995.00, crashed many times while I was trying the demo version of it. ProCad32, Protel98, Ivex, and even the Eagle demo all have crashed. Protel98, being nearly $5k, crashed at the drop of a hat. I wasn't terribly impressed. The most common crash scenario is dorking around with the programs when you don't know what you are doing. This makes sense, actually, because you are probably doing steps that the test engineers never thought about covering (ie completely random non-sense). These are also extremely difficult to reproduce, since the user more than likely doesn't know how they created the crash since they didn't know what they were doing in the first place. Not really a good excuse, but it is reality with any complex software. If you don't feel like spending too much money, the latest version of the IVEX program is pretty good. You can get 300 pins worth for $99 a program. That will do a fairly decent sized board for the hobby level. I am going to play around with Eagle some more, based on Rogers recommendation.

[begin of article] Digital sensor provides serial data output Pembroke, Mass. -- Ritchie Navigation has developed a digital electronic heading sensor that provides serial data output. The DH-0200 can be easily interfaced to most systems, according to the company. Serial output data is based on the marine industry- standard NMEA-0183 format is directly compatible with the serial port of most PCs. The format is a 4,800-baud ASCII character string that contains heading resolution to 0.1 degree. The sensor provides deviation compensation software that automatically corrects for the magnetism present on the host-vehicle platform. The basic accuracy of the sensor after compensation is +-1 degree. It is internally gimballed for +-45 degrees of pitch and roll. Developed for use with marine radars, autopilots and navigation equipment, the DH-0200's rugged, watertight and compact design (10.5 x 7.5 x 10.1 cm) makes it suited for applications in GPS, robotic-vehicle navigation, oceanographic instrumentation and data collection. The sensor requires a single 12-VDC, 50-mA power supply. It costs $99.98 in OEM quantities.

Maritime, not navy. Magnetic compasses are of course very sensitive to stray magnetic fields both those generated by fixed magnetic and by electromagnetics. In the old days, it was a severe infraction to tamper with the ships compass. The ships compass used a few things to keep the compass as stable as possible. One of these you may have seen, large iron balls situated on either side of the compasses. The nickname for these were navigators balls. These were to reduce the effect of stray magnetic fields. I expect that the compasses that we are going to be used will be effect by the electric motors, power lines and other electric fields. So the best solutions is to remove the compass from the area of these fields. I understand that Roger did this by putting the compass on a mask on his bot. That should work. Obviously, shielding the compasses won't work, because you will also shield it from the surrounding earth's magnetic field. Shielding the electronics and the motors maybe a more viable solution. True headings and compasses headings. To get a true heading from your magnetic compass there is a formula for it, and as you know sailors have sayings, so I will give you those too. C + D = M + V = T, compass heading plus deviation = magnetic heading plus variation equal true heading. Deviation is the change in heading due to the local magnetic fields, i.e. what your robot deflect the heading by. Magnetic heading is the direction to magnetic north. Variation is the difference between magnetic and true north. It can be found on charts and in some navigation book. In fact my owner's manual for my Explorer has a chart with variation for North America. Now for the saying so you can remember them. True heading to compasses head: True Virgins Make Dull Company. Compass heading to True heading: Can Dead Men Vote Twice. I hope that you enjoy this little primer, and I too enjoyed RBNO last week, I cant wait till next time.

If you follow the newsgroups such as sci.electronics.cad (if I remember right), Protel 3.0 was very buggy, causing designers to lose even already-written pcb layout data. I'm sure Protel98 is just a follow-on product. Protel has been losing market share for some time now to companies like Pads and OrCAD. On the high end, Cadence is trying to cost-reduce their Allegro tool for NT (which in Unix runs about $65,000, and in NT runs about $30,000!!!), but I haven't heard much good about its cost-to-benefit ratio. I've been using Pads PCB (a DOS shareware version) for about 14 months now, and I've never had it crash. No, not even one time. So it is possible to write software that doesn't have crash-causing bugs. I'd say if you have the $1500 to spend, check out Power PCB from Pads. I'm sure it beats Protel, Tango, Microsim/OrCAD, or any other mid-range products, although I haven't personally tried it.

I know that most times when I try to reply to spams, I get the mail-daemon message that you speak of. I was going to make a spam list of spammers. everytime I received a spam I wanted to add the sender to the list, then forward the message to everyone on the list and see how they all liked it. Unfortunately it didn't work. If it did, I would have started a chain letter explaining the process.

If you look at such projects as Boris or Stiquito, they just don't have too power to do much useful other than for demonstration purposes. Most times, the heavy stuff like the batteries and CPU board will not be on the robot (tethered) because the muscle wire is just not strong enough to work with them on board. Except for demonstration purposes, muscle wire is not that practical yet. Maybe if they make a new and improved more power version of muscle wire will it be something to look into. - - - ____ - - - - - - ___ - - - - - - - - - - - - - - - - - - - - - - - - - - \/\_\@ ____ / /\ __ ___ ___ http://www.dprg.org 05-16 / / /\ / / /\ /--/ //\_\/\_/\ /\/\/\ /\_/\ jbrown@cyberramp.net /__/ / / // / / / /__/ // / /__/ //_/_/ // // / (972)519-2868, (972)495-3821 \__\/ \/ \/\/\/ \__\/ \/ \__\/ \_\_\/ \/ \/ jgbrown@spdmail.spd.dsccc.com http://www.cyberramp.net/~jbrown www.geocities.com/TimesSquare/Castle/6818 ------------------------------ From jbrown at cyberramp.net Thu Jun 4 08:29:42 1998 From: jbrown at cyberramp.net (Jim Brown) Date: Thu Feb 15 16:50:51 2007 Subject: DPRG: BOUNCE dprglist@dprg.org: Non-member submission from [Ralph Tenny ] Message-ID: >Return-Path: >From: owner-dprglist@dprg.org >Date: Wed, 3 Jun 1998 10:25:18 -0500 >To: owner-dprglist@dprg.org >Subject: BOUNCE dprglist@dprg.org: Non-member submission from [Ralph Tenny ] > >>From owner-majordomo@horta.ncc.com Wed Jun 3 10:25:16 1998 >Received: from nimon.ncc.com (nimon.ncc.com [199.1.173.2]) > by horta.ncc.com (8.8.5/8.8.5) with SMTP id KAA14951 > for ; Wed, 3 Jun 1998 10:25:16 -0500 >Received: from rten@polaris.nstar.net [209.131.128.2] by nimon.ncc.com (OS/2 NCCmail v0.33) with SMTP > for dprglist@dprg.org; Wed, 03 Jun 98 11:18:52 CST >Received: from localhost (rten@localhost) > by polaris.nstar.net (8.8.8/8.8.8) with SMTP id LAA23226 > for ; Wed, 3 Jun 1998 11:21:11 -0500 (CDT) >Date: Wed, 3 Jun 1998 11:21:11 -0500 (CDT) >From: Ralph Tenny >To: dprglist@dprg.org >Subject: RE: DPRG: Eagle PCB layout software question >In-Reply-To: <9806038968.AA896888703@mail.rudolphtech.com> >Message-ID: >MIME-Version: 1.0 >Content-Type: TEXT/PLAIN; charset=US-ASCII > >How many holes are there in a PCB primarily for surface mount (smp) parts? > >I think my current project can be laid out with all smp to >make a single-sided board. > >At the job I recently retired from, I worked mostly with smp.

Ok, that's basic, but lets say you want a MCU to control the motor direction, how would you do it. Well, for starters you get a transistor, and hook up the motor like so: +12v | +----( motor )----+ A function | -- ------- \ 1 forward |-----/\/\/---- (A) 0 stop / | gnd or: +12 | +----( motor )----+ B function | -- ---------- / 1 reverse (B)---| 0 stop \ | gnd If you hook these up in this fashion, you only get stop and one direction. You can also pulse the on and off and get varying degrees of torque which usually translates to speed the motor turns. But, if you want to do both forward and reverse, you need an h-bridge (notice the H configuration): +12 +12 | | / \ (A)---| |---(B) \ / | | A B C D function +----( motor )----+ - - - - ---------- | | 1 0 0 1 forward / \ 0 1 1 0 reverse (C)---| |---(D) 1 1 0 0 break (motor won't turn) \ / 1 0 1 0 fuse test (don't do this) | | 0 1 0 1 fuse test (don't do this) gnd gnd So, you turn on the upper left and lower right transistors, and power flows through the motor forward, and then for reverse you turn on the upper right and lower left transistors and power flows through the motor in reverse. You should be careful not to turn on one side or the other, or you have a dead short which will fry your circuit. If you turn on the two upper transistors, the motor resists turning, so you effectively have a breaking mechanism. To be nice to your transistors, you should add diodes to catch the back voltage that is generated by the motor's coil when the power is switched on and off. This flyback voltage can be many times higher than the supply votage! If you don't use diodes, you could fry your transistors. +12 | +-+------+------+-+ | | | | / | | \ (A)---| - - |---(B) \ ^ +---||----+ ^ / | | | | | | A B C D function +-+-+( motor )+-+-+ - - - - ---------- | | | | 1 0 0 1 forward / | | \ 0 1 1 0 reverse (C)---| - - |---(D) 1 1 0 0 break (motor won't turn) \ ^ ^ / 1 0 1 0 fuse test (don't do this) | | | | 0 1 0 1 fuse test (don't do this) +-+------+------+-+ | gnd Transistors being a semiconductor device will get hot and they can't sink or source very much power. Mosfets are much better, they can pull much more current and not get hot, they usually have the flyback diodes built in so you don't need the diodes anymore, and they're less likely to fry your mcu so a resistor between the mosfet and the mcu is less necessary. To use mosfets in an h-bridge, you need P-Channel mosfets on top because they "source" power, and N-Channel mosfets on the bottom because then sink power. Some clever people manage to use N-Channel mosfets on top by overcomming the breakdown voltage of about 7volts higher than the supply voltage (N-Channel mosfets are much cheaper than P-Channel mosfets). There are premade H-bridge chips that are much easier than desiging your own h-bridge design. The L298 has 2 h-bridges on board, can handle 1amp and peak to about 3amps. The LMD18200 has one h-bridge on board, can handle about 2 or 3 amps and can handle a peak of about 6 amps. There are other h-bridge chips as well. These h-bridge chips can usually handle a motor the size of a coke can or smaller. There - probably more than you cared to know about controlling a motor and h-bridges! - - - ____ - - - - - - ___ - - - - - - - - - - - - - - - - - - - - - - - - - - \/\_\@ ____ / /\ __ ___ ___ http://www.dprg.org 05-16 / / /\ / / /\ /--/ //\_\/\_/\ /\/\/\ /\_/\ jbrown@cyberramp.net /__/ / / // / / / /__/ // / /__/ //_/_/ // // / (972)519-2868, (972)495-3821 \__\/ \/ \/\/\/ \__\/ \/ \__\/ \_\_\/ \/ \/ jgbrown@spdmail.spd.dsccc.com http://www.cyberramp.net/~jbrown www.geocities.com/TimesSquare/Castle/6818 ------------------------------ From jbrown at cyberramp.net Thu Jun 4 09:22:27 1998 From: jbrown at cyberramp.net (Jim Brown) Date: Thu Feb 15 16:50:51 2007 Subject: DPRG: Robots..

The problem is power and contraction/expansion time. NiTi wires can lift weights up to a kilogram for larger thicknesses (still about as thin as a hair). Several years ago Hitachi made the "Hitachi Hand" which used NiTi wires in bunches of four for each of the hands three fingers (12 in all). This hand could manipulate small objects very well. I think the biggest problem with Muscle wires is attaching them, and thier cool off rates. Check out mondotronics or thier kit for experimenting with NiTi wires.

For those who haven't, I'll be happy to try to meet for lunch next week with you. Maybe we could do a Paradise Burger (Plano Parkway & Central) run next week if anyone is interested. Maybe Wednesday at 11am? For those who want one, they'll be $13.50 each. For those who care, please add 0.25cents to cover the shipping from Idea-Vision. Add another $3 if you want me to mail it (them) to you ($3 should cover the shipping for at least 5 sonars is my guess, maybe 10). BTW, I won't be at the next meeting, (Clay will take over while I'm gone) so you'll have to get with me at the meeting after next if we can't meet for lunch someplace. When I get home, I'll try to make a list up of who has paid, who I have records as wanting one, and how many are free for the asking. Last I remember, we only needed to order about 25 or so, and we purchased 50, so I think there's plenty if anyone wants a few extras or hasn't asked yet.

(Sort of a joke about preachers that predict the end of the world and it doesn't come true). Under Word Records in Waco, or Myrrh (not sure at the moment). The tape came out about the time when christian new wave was in. It's sort of a really weird tape. I've heard comments about his music, ranging from, he brought christian music into the 90's to that's something my dog wouldn't even like listening to. So purchase at your own risk. I'm sort of strange, so I really like it. Steve has the following albums: I want to be a Clone, Meltdown at Madam Teasoudes, On the Fritz, Babylon 1990, Squint, and another album singing for Chegall Geverah. He also made a remix album with Sheliah Walsh, and a few other miscellaneous places. All of the lyrics are very forthright and clevar unlike most other musicians that barely can sing anything more than "God is so Good" wit. If nothing else, it's candy for a swirling brain, that's probably why I like it. Some of his music is contraversial, like the one song that many misinterpret called "I blew up the clinic real good." At first glance one would think the song is promoting that, but when you listen to the song, you realize how perposterous he makes that haneous act and how stupid the people who do it must be. Other songs like "I want to be a clone" show how christians all try to fit into some kind of unrealistic mold, learn the christianese language, and do what are thought to be christian things to fit into what others think christians should be but really aren't. Lifeboat is a song about "values clarification" that was popular for some time, like who is worth living, a doctor or a street cleaner where some try to put one life as more valuable than anothers, or not necessary - ie: they're not a productive member of society, so... Anyway, after you listen to all of his albums, you'll quickly realize why I'm such a twisted and swirling brain. The group Daniel Amos was also very influential if you want to look them up too. They sometimes just go by "DA" (abbreviation for Danial Amos). Talk about weird, but that's what my swirling brain feasted on while I was growing up and made me what I am today. Another artist I like is Bryan Duncan who is somewhat normal and sort of more leaning towards jazz style. FYI: some of my swirling brain stories at: http://www.cyberramp.net/~jbrown/stories.html I'll try to post more sometime. - - - ____ - - - - - - ___ - - - - - - - - - - - - - - - - - - - - - - - - - - \/\_\@ ____ / /\ __ ___ ___ http://www.dprg.org 05-16 / / /\ / / /\ /--/ //\_\/\_/\ /\/\/\ /\_/\ jbrown@cyberramp.net /__/ / / // / / / /__/ // / /__/ //_/_/ // // / (972)519-2868, (972)495-3821 \__\/ \/ \/\/\/ \__\/ \/ \__\/ \_\_\/ \/ \/ jgbrown@spdmail.spd.dsccc.com http://www.cyberramp.net/~jbrown www.geocities.com/TimesSquare/Castle/6818 ------------------------------ From dannyabc at gte.net Fri Jun 5 18:32:59 1998 From: dannyabc at gte.net (Danny) Date: Thu Feb 15 16:50:51 2007 Subject: DPRG: EAGLE PCB software on sale Message-ID: I saw CadSoft's add in Popular Electronics, and called them up today.

A few people us them in home automation because, they can be daisy chained and are farely cheap. There is a bunch of diffrent languages too. You will need a programmer, but the srs has a pic programmer that a baby could build. If you can't build this programmer, you can't automate a house. Ona Second note, i bought a ibm home director for $40 a week or to back. Automates the house very easy with a comp, you can also get a remove controll. In the long run, it's cheaper then a pic and all nessary equipment. The Modules sell for $10 - $12 and come in many diffrent formats. Wall switch, appliance module, lamp module (actual dims a light to nessary brightness). I have it so that when i get up, it turn on my upstairs light, and it toast my pop tart. Hope this helps.

A theatre I do some work for wants to automate their lightboard on a budget. Their board consists of two 12 channel fader modules which use analog techniques to produce 0-100% duty cycle PWM for each channel. The PC board and application will need to be able to sample pulse width and record changes on all channels for later playback.

Ultimately, this may be the only way that BC can compete with Chile, with whom Canada is negotiating a free trade agreement. clipped. Forwarded to note one point: "fully automated systems". Now what if False Creek were to purchase a Japanese Mega Float (http://users.uniserve.com/~culturex) and fully automate it, using aquaculture as the food base? With a central AI brain and many appendages (manipulators) the citizens of the Mega Float would be living in a robot. Not all food would have to be sea food as sheep farmers on the Orkney Islands for example use kelp to feed their sheep.

A lot of the schematics I'm downloading over the net were obviously done by somebody with one of those obscenely large (between 21" and 6' I think) monitors. Problem is they fill at least two screens on my 17" even when it's set to 1280 x 1064 (I think that's it any how). I can't get the !@#$ things to print out because they will also fill more than one printed page. So far I've found no way in Netscape or Explorer to 'scale' the net page size to fit the printer paper. If its longer it prints as a second page but if its too wide it just gets cut off.

Let's see, government spending billions of tax dollars to build a 'city' with a central control system, call it a 'robot' if you want. Hmmm.... that way the 'robot' can tell people where to go, at what time, and what to do while they are there. Hmmmm..... that way it's not the government controlling things it the AI right????

I think you are correct that there are such risks in using such new technologies. Here I am with my personal robot in hand-my Reprogrammable, Multifunctional Word Manipulator. (RMWM). Does it or does it not fit the definition of a personal robot? yes/no. Consider the risks here. In 1994 the AT&T newsletter stated that their goal was to develop "natural two-way communication between people and machines by 2001". That's an exact quote. Now what if a prankster at AT&T were to release such a program via a RMWM on an unsuspecting internet community? We could end up engaged in furious debate on the mailing lists with "Bruce the Borg" and not even know that we were interacting with a machine. > Can you say 'George Orwell' ? (spelling?)

If you imagine the "Era of Personal Robotics" coming in via human-appearing tin men running around homes even then you have risks.

This list is about PERSONAL ROBOTS. Japan has a national policy which was reviewed by Discovery Ed. TV last week. It is "Project Humanoid". They are using a lot or research centres especially the top universities to develop human-looking robots which would be personal servants. Some models were very impressive. One prof. at Tokyo Institute of Technology disagreed with the dominant trend to make these machines look like humans. There are psychological implications which I think he is right about (my doctorate is in phil/psych). My AI/computing science prof at U of A where I got my doctorate insisted again and again that "computers are incredibly stupid". With all due respect I have to wonder now. One branch of AI researchers in the US are calling themselves AL (artificial life) researchers. At what point do you start to wonder if that very human-looking personal robot is human? At what point could the AI unit become autonomous? Really autonomous. And there is another list which goes by that name. I'm not advocating any of these abuses and you won't find a single posting which says that I do. But you are right to be concerned about them. All I am advocating is that a village like False Creek make the best use of automation and that means looking into the use of personal robots.

Please stop pushing your advertising on the DPRGlist. It is quite apparent that you do not respect our list and are using our list only to further your own. Why would you want to do something like that? Do you feel that it is your right to abuse other's lists for your own means? YOUR project sounds nice, and I hope you do well on it. Don't let that make you feel like you can go around and abuse other's lists to further your purpose. I for one, after working very hard to keep our list advertising free, do not appreciate people like you getting on our list just to spam it with your endless emails. Go somewhere else if that is what you want to do, or you may stay if you want to only chat about personal robots and dprg stuff. I'm trying to pleasantly ask that you discontinue your constant advertising of your project, your list, and to let us get back to DPRG business and personal robotics, that what this list is for, not babeling on promoting and advertising your "great" new project. If it's such a great thing, go to CNN and promote it, or get on TV or Radio. - - - ____ - - - - - - ___ - - - - - - - - - - - - - - - - - - - - - - - - - - \/\_\@ ____ / /\ __ ___ ___ http://www.dprg.org 05-16 / / /\ / / /\ /--/ //\_\/\_/\ /\/\/\ /\_/\ jbrown@cyberramp.net /__/ / / // / / / /__/ // / /__/ //_/_/ // // / (972)519-2868, (972)495-3821 \__\/ \/ \/\/\/ \__\/ \/ \__\/ \_\_\/ \/ \/ jgbrown@spdmail.spd.dsccc.com http://www.cyberramp.net/~jbrown www.geocities.com/TimesSquare/Castle/6818 ------------------------------ From culturex at vcn.bc.ca Sun Jun 7 16:52:35 1998 From: culturex at vcn.bc.ca (Franklin Wayne Poley) Date: Thu Feb 15 16:50:51 2007 Subject: DPRG: Living Inside an Autonomous, Personal, Self-Evolving Robot.

Perhaps I misunderstood. Is this list only for people who want to build their own robots? What I had in mind was buying ours on the world market. I wouldn't build my own robot any more than I would build my own pc although some people do it. > The DPRG list is just not the place to discuss False Creek.

So the issues I am interested in are more on who to buy from, what is a good buy, reputation of dealers etc. My apologies if I misunderstood the list charter. I think we are at a stage in the development of the robot industry at which the personal robot is about to take its place on the consumer market alongside the personal computer. But there are lots of ways in which this could take shape. The co-operative effort of a community of 5,000 or 10,000 with its great buying power is one way but that depends on getting over technophobia and seeing the value of the robots. That is what I had hoped to learn from these lists-more information which the layman would find useful in making buying decisions.

IBM tryed it in the eighties along with TI and they both gave it up after spending TONS of money. NASA spend TONS of money at AI and got no where. The government of the United States has funded so many projects relating to AI they are too numerous to list her on this ROBOTICS SITE. Your project involves the networking various systems to function as a group and that Im shure is not the focus of the group. AI is an interesting concept but, at this state of the game I think we all need to concentrate on smaller projects that might be able to fix my breakfast and take out the garbage before I let it run my life. When you can prove to me that a autonomus robot can exist without a human intervention then you might have something. And dont try to tell me that the mars rover is autonomous all it is, is a real expensive remote controlled car that probes soil and air for samples. When you can make real contributions to the group and to the various projects on the table you can have my vote. Untill then, give it a rest and let the rest of us continue with our discussions about robotics. And by contributions we mean real solutions not esoteric or socio-dynamic excential flamboyant more money than I will have in my life time ideas.

Good results with both. I highly recommend the AT90S series for its simplicity, availability, and low overall cost (a programming cable consists of some resistors and a capacitor). The low-end chips start at $3.00 each from Insight Electronics, and all of this series have built-in oscillators if you don't want to use an external crystal. Regards, Daniel Herrington P.S.

I am attempting (with better luck than before) to lay out a PCB for connection to the FlashLite controller. I think I have the Hewlett-Packard HCTL-1100 motor controller about 70% figured out. If it all comes together, FleaBot will have a really really good understanding of not only where he is, but where he's going. OK, OK, I admit it. I am green with envy over the navigation of Dave Anderson's 'bot and this is an attempt to implement a similar scheme for FleaBot. My question is, what value(s) of bypass capcitors should I use? So far, I have .1" spaced pads placed near Vcc of each gate, the Vdd pins of the controllers and the logic power pin of my H-bridge. The design will use a single 9.6V (maybe up to 12V) NiCad battery string for motor power with a low dropout 5V regulator (Thanks to Ed Koffman) supplying logic from the same battery. The board is designed to plug right on top of the FlashLite PC, though it is a little bigger on all sides. It will look a little like the breadboard I/O (http://alias.flash.net/users/slugmusk/fleaboti.jpg) that I started on for the Fire Fighting Robot contest. The HCTL-1100 controllers are 40 pin DIPs, which eats a lot of room on the board. They are available as PLCC, but that's not really that much smaller. The application notes show one XOR and four NANDS to connect the PWM and direction outputs to the H-bridge. I think I could accomplish the same thing with fewer gates.

I am attempting (with better luck than before) to lay out a PCB for connection to the FlashLite controller. I think I have the Hewlett-Packard HCTL-1100 motor controller about 70% figured out. If it all comes together, FleaBot will have a really really good understanding of not only where he is, but where he's going. OK, OK, I admit it. I am green with envy over the navigation of Dave Anderson's 'bot and this is an attempt to implement a similar scheme for FleaBot. My question is, what value(s) of bypass capcitors should I use? So far, I have .1" spaced pads placed near Vcc of each gate, the Vdd pins of the controllers and the logic power pin of my H-bridge. What (if any) should be placed around the regulator or battery input or anywhere else? The controllers will probably be clocked at 2MHz derived from the V25, but as I read, that may make my lowest speed too fast. Will have to breadboard the thing to determine all that. The design will use a single 9.6V (maybe up to 12V) NiCad battery string for motor power with a low dropout 5V regulator (Thanks to Ed Koffman) supplying logic from the same battery. The board is designed to plug right on top of the FlashLite PC, though it is a little bigger on all sides. It will look a little like the breadboard I/O (http://alias.flash.net/users/slugmusk/fleaboti.jpg) that I started on for the Fire Fighting Robot contest. The motor controller has several modes and features such position and velocity control, trapezoid movement profiles, decelerated stop, multi-controller sync. It can commutate brushless DC motors or steppers, or control DC motors with either PWM or a DAC. The tricky bits are that I must interface it with my processor's bus and most of the values are passed to it as 2's complement data. I'm familiar with the general concept of 2's complement, but I will need to brush up on it a bit. Luckily, the appnotes have assembly examples for 8051 and 'HC11. The HCTL-1100 controllers are 40 pin DIPs, which eats a lot of room on the board. They are available as PLCC, but that's not really that much smaller. The application notes show one XOR and four NANDS to connect the PWM and direction outputs to the H-bridge. I think I could accomplish the same thing with fewer gates. I would do it by feeding the PWM to the H-bridge enables and the NANDs to the inputs, eliminating the XOR. Any thoughts on that? Something that has help TREMENDOUSLY with this is the set of Data CD-ROMs I got from TI.

I was looking through the documentation and wondering if I could pull the L293 chips from the controller that I'm now using (MIT 6.270 board), build a header to plug in there, and use the same control lines (and software!) to drive the 298? I have done this before to drive a pair of Polaroid sensors from the expansion board '293 socket, a quick and dirty way to get 6 output bits. The '293s on the main board are controlled by only 4 bits, 2 chips selects (motor enables) and two "direction" bits that are split into inverted/non-inverted pairs for the '293 direction A and B inputs. Might this work also for the L298? In an unrelated matter ... following a suggestion of Mark Sims of STB here in Dallas, I taped some red and green plastic film from a cheap pair of cardboard 3D glasses over two cadmium sulfide photo cells, attached to two A/D inputs of the HC11, and measured the ratio of the two when pointed at coke (red) and 7up (green) cans, to see'f I could tell the difference. Looks like it might actually work, such that a can collectiing robot might be instructed to collect only the red or green cans, or better yet, collect both and make two piles!

I think what you're referring to goes something like this: +-------- (lamp) ----------+ | | +------ (-battery+) -------+ gnd +1.5 +-------- (lamp) ----------+------- (lamp) ----------+ | | | +------ (-battery+) -------+------ (-battery+) ------+ - -1.5 gnd +1.5 or gnd 1.5 3v True ground should be zero volts, but frame ground (attached to the metal frame of your gizmo) may not be actually be zero volts - therefore ground would be relative. >Do you need to ground unused inputs/outputs of an Op Amp? I am currently >using a LM339 from Radio Shack if that helps. > >Are there any general 'rule of thumb' on using Op Amps? I suppose this is a little grey area for me. I think a normal opamp like a 741, if you left some of the pins at no-connect, you get a certain type of high gain, so I guess that's ok. Generally, on any chip, you want all of the pins tied to something unless the spec says otherwise. A 339 however, if memory serves me correct is not your normal general purpose opamp, it is a comparator. Basically, you set on one of the inputs your threshold voltage, and the other pin a varying voltage. When the varing voltage goes above your threshold voltage, the output turns on, and when it goes below, the output turns off. >Questions about Transistors: > >How can I know what type of transistor to use in a circuit?

At first grin, I'd say look at the spec to find the device you need. I'm not sure which device you are trying to operate, but if it's a motor, a transistor may not be the device you want to use. You may want to use a mosfet. General purpose transistors (2n2222, 3906) are more for signal level ttl stuff. You can turn on leds and such, but they probably can't take much more current than that. You can get more powerful transistors but transistors are a semiconducting device, that means resistance, and that means heat output. If you're going to get into something that requires a lot of current like a motor, switch to a mosfet. Mosfets can pull many amps (like 30 or 60 amps), and can handle the heat much better. There are two types of mosfets, just as there are two types of transistors. The N-Channel mosfet sinks power, and the P-Channel mosfet sources power. Sinking power: +12 | +---- ( motor ) ----+ | \ N-channel |-------- cpu Mosfet / | cpu Sourcing power: +12 | \ P-Channel mosfet |-------------------------- cpu / | +----- ( motor ) ----+ | gnd By the way, if you're going to control a motor, try looking up some chips that are already designed to that like an L298 an L293D, or LMD18200! They provide motor direction control by what is known as an h-bridge configuration. >Thank you in advance for your help. > >I've enjoyed your web site.

Message-ID: Ed Koffeman's video techniques are still quite intriguing... I spent some time yesterday browsing for frame grabber technology and it occurred to me that just about all is hi resolution RGB and for navigation as I see it, most video systems are monstrous overkill. What I think I want is something with about 64x64 pixel resolution at probably no more than 256 grays. That would yield an array of 4K bytes that even a fairly elementary C program could process that at an acceptable frame rate. What I would like to do is find some details on the RS-170 or NTSC or whatever standard monochrome security cameras adhere to. I have several of that type of camera, though none are especially small. If the output from these cameras is 525 lines, I could put together an ADC system that samples every 4th line of a field 64 pixels wide and puts the data in a 64x64 array for analysis. The second field could be ignored. The application could grab a frame (field) whenever it wanted one. To further clean this up, a dedicated micro could run the ADC and pass off the last frame it captured when requested by the controller. I think that this level of complexity could be managed by a smaller MCU than full bandwidth video and perhaps could fit on FleaBot (the driving force behind many of my off-the-wall miniaturization ideas) Robert - -- ------------------------------------------------- There are two rules for ultimate success in life: 1.

Wow. From the great Jim Brown's fingers. I like it! 8-) Here's a good selection of boards http://www.interlog.com/~techart/ They have a board with this cool uncertified chip that let's you hook up the 32k's in expanded mode, and has 8k's EEPROM on board. Price for normal board(minus external mem)? $39 pre-assembled. Don't bother buying the kit, too much for very FREE stuff. If you are feeling lucky, you can wrap your own. Either wire wrap or you could put it on a stripboard and solder each wire to other components. Someone mentioned using conventional wire wrap sockets for the PLCC sockets to wire wrap, which sounds good.

Oh oh, I feel another CPU war about to break out! Be easy on me! Realistically, though, HC11's are a nice chip, no doubt. I don't use them, because I'm already familiar with 8051 architecture. Probably many hc11 folks wouldn't *step down* to an 8051 or a pic because they are familiar with hc11 architecture. The two main reasons I don't like the HC11 is that it seems that the HC11 are more costly, and not always the best choice for every design. Someone who tries to use an HC11 for everything is just as bad as someone who tries to use an 8051 for everything. You wouldn't want to use an HC11 where an 8-pin pic would be better, and you wouldn't want to use a HC11 when you need 50mips. Also, why would I want to pay $12 to $25 a chip when I could pay $0.50 to $5 for a chip that I can make do what I need? There are 8051 variants that do all an hc11 can do and maybe cheaper, but hc11 diehards would never consider them, for whatever reason. If you plan to only make one of something, maybe $18 is not an issue for a chip, but if you wanted to make 5 or 10 or 100 or something, it seems that it could be a problem. For autos (it's biggest market), cost of the chip gets eaten up by the price of the car, but for most gizmos, price of the chip matters. Maybe that's why there's only 1 hc11 maker, and bunches of 8051 & pic type makers. So yeah, an HC11 is the better chip, but I'm cheap, that's why I go with the 8051 stuff. Yeah, I'll admit that. Burning vs. downloading is solved by using an eprom emulator. To me, anything grander than an 8051, you might as well step up to a PC based board like the one Robert was using. It's like in the old days every little computer tried to say how you could upgrade it to be like a PC but never was a PC and costs hunderds to upgrade. It seems that I always hear about people having problems with their hc11, and how to proto them. If they're so great for the prototyper, how come it's near impossible to prototype them. You end up buying a prefab board ($15 bucks) that's not necessarily what you want, or you have to design and build your own board and get charged a bundle. I guess what I'm saying, is that for the nice chip, it's like shooting yourself in the foot. If I wanted to pay $60 or $80 for a board, I might as well skip to a PC and do it right. Even with my piddly little 8051 board, I'm considering going to a PC. It's like the HC11 is too little too late. With as cheap as PC's are, it seems that HC11's are becomming as obsolete as the 8051. That doesn't mean I'll stop using my favorite chip, nor do I expect yall to stop using your favorite chip, but really, though, we should be stepping up to something better instead of bickering over these little piddley do dads. 8051s and hc11s will the the perifreal chips of the future, not the main brains, unless you want a piddley robot and everyone else surpass you. Let your 8051 or hc11 do motor control, and sensoring, and video, and whatever, but if you need real power, get your ram, mips, and disk space with a pc bot. - - - ____ - - - - - ___ - - - - - - - - - - - - - - - - - - - - - - - - - \/\_\@ ____ / /\ __ ___ ___ http://www.dprg.org (June20) / //\ / / /\ /--/ //\_\/\_/\ /\/\/\ /\_/\ jbrown@cyberramp.net /__/ // // / / //__/ // / /__/ //_/_/ // // /(972)519-2868, (972)495-3821 \__\/ \/ \/\/\/ \__\/ \/ \__\/ \_\_\/ \/ \/jgbrown@spdmail.spd.dsccc.com http://www.cyberramp.net/~jbrown www.geocities.com/TimesSquare/Castle/6818 My employer won't claim these opinions so I'm giving them away for free. ------------------------------ From jbrown at cyberramp.net Thu Jun 11 19:14:23 1998 From: jbrown at cyberramp.net (Jim Brown) Date: Thu Feb 15 16:50:52 2007 Subject: DPRG: dinsmore compass and sonars..

I'm not nearly as advanced in electronics as most of DPRG is. but I'm learning. :) There's 4 connections to make: Power, Ground, trigger, & echo. You turn on the power, then wait 5ms, then turn on the trigger, then wait for the echo to go high. To do another measurement, you have to turn off the power, wait 75ms, and then repeat the above steps. It comes with a schematic that shows using a regular 2n3906 transistor to turn the power off and on, and that it's possible to control the thing with just two i/o lines (1 for turning the power on and off, the other for both turning on the trigger and monitoring the echo line), however, I'll probably use 3 i/o lines to do it. There's not a header to solder to, you have to solder directly to a chip, but it doesn't look too hard.

Lots of good stuff on the mail list this week. I just got through reading in the Xilinx data books a recommendation to use both 0.1 and 0.01 bypass caps on their cpld's. This has been my policy for about 7 years now. Both values of caps are required because the small lead inductance combined with the small capacitance forms a bandpass filter that limits the ability to absorb switching noise. I prefer to use monolithic ceramic caps mounted as close to the PCB as possible. I'm pretty shure rezolutions below 720 by 525 won't give my robot a clear outlook on life, but if you are going to subsample NTSC video I suggest passing it through a low pass filter before the ADC. If you don't, the image will have a poor "fill ratio" (pixels represent small image areas seperated by incogruent space) leaving sharp contrast steps between pixels. Low pass filtering will leave the image more pleasant to the eye and easier on (some) edge detection algorithums. Vertical axis filtering is computationally intensive and probably unnecessary with the LPF. P.S. There is no such thing as digital electronics, only the digital characterization of analog signals.

Message-ID: I just found a news tidbit, which may be of some interest to this list. Sony proposes open architecture for entertainment robots By Yoshiko Hara TOKYO — The folks who brought you the Walkman are readying what they hope will be the next big fad in personal entertainment: robots. Sony Corp. has proposed its freshly minted Open-R (Open Robot) architecture as an open platform for a market niche that does not yet exist. "Sony wants to create a very new entertainment robot market," said Toshi T. Doi, president of Sony's D21 Laboratory, which pursues digital technologies for the coming century. "We have developed the Open-R architecture and want to invite many companies to join the entertainment robot arena based on the format." Entertainment robots, as Sony defines them, are consumer products designed just for play. Sony researchers demonstrated robots scampering after a ball, kicking it and exhibiting other behaviors sophisticated enough to give people the illusion they were playing with a puppy or a kitten. The little tykes walked, sat, stood up, lay down and rolled over on their backs. The prototype robot is about the size of a very small puppy — roughly three pounds and 5 x 10 x 9 inches. It runs on a 64-bit MIPS RISC processor with 8 Mbytes of DRAM and a newly developed IC. This core system controls attached hardware modules such as head, legs, hands and tail, each with motors and a control chips of its own. A 180,000-pixel CCD sensor works as the robot's eye, and a microphone and speaker do duty as ear and voice. Application programs — in the demo they were pet behaviors — are implemented by way of PC cards. Tomorrow's toy Though Sony has not yet made a marketing plan, Doi said the company is aiming to have some form of robot product out before the end of this century. "We have no idea how big the market will be," he said. Built around Sony's proprietary Aperios real-time operating system, the Open-R architecture makes it possible to change a robot's body by exchanging hardware modules — substituting a wheel for the back legs, for example. The CPU communicates with each module through the 12-MHz, 12-Mbit/second Open-R bus, and makes an optimum setting based on the parameters stored in the module. Therefore, the modules support hot plug, sort of like an electronic Mr. Potato Head. "There are various applications available in PC card form, such as wireless LAN. Open-R robots can make use of them as is," said Doi. Sony developed a chip of about a half million gates that integrates a DSP and graphics-processing engine for signal and IF processing. Sony does not yet have a practical plan of how it will license the architecture or offer the chip, according to Doi. Sony will stage exhibition soccer games using the prototype robots at RoboCup '98, an academic conference on robot technology to be held in Paris July 4-8. Sony has provided robots to research groups at three universities — Carnegie-Mellon in Pittsburgh; Osaka University in Japan; and to a university in Paris — and the three teams are developing software. In the exhibition games, three robots on a single team will match with another group's robots independently, without any remote control. == Paul Jurczak _________________________________________________________ DO YOU YAHOO!?

However, lately, there are some real contenders in the embedded controller market that offer signficant performance but are still quite embedded. I'm thinking of using the SH1 from Hitachi for my controller stuff as it is cram packed with high performance peripherals and a GNU C++ compiler is available for it. I want to use a Pentium based PC as an image processor (machine vision) for the most part, but I haven't determined if my robot consciousness will reside on a powerful embedded controller, or on the PC, or Both! (if you're following the latest in distributed techniques). I partial to embedded control ... what's to bet that that's where my consciousness ends up! Knowledge based expert designers will of course want to take advantage of the PC for it's database and retrieval capabilities.... I'm not quite there yet. However, the PC is no embedded controller !!!! It will be difficult to make things happen using 1 millisecond timers on the PC. Plus, taking advantage of what the PC offers means that practically all of the on-board peripherals of a PC are off limits! This doesn't leave much resources for the huge demands of a complex robot. That's why I want to keep the PC down to doing big number crunching jobs, but very little real-time control stuff. It'll be interesting to see how it all works out. For those going full bore with a PC, remember that Windows is a completely different paradigm. Those wanting simple DOS should just stick to powerful embedded controllers, unless you take advantage of 32 bit DOS, which can be done using Watcom or other 32 bit compilers. Bill is still at it again ... attempting to take over the embedded world with Windows CE. That will be interesting too, as Microsoft has geared up to invade and dominate the embedded world!.

The contest is set for our September meeting (12th), but it's not really a "maze-solving" in the strictest sense. It's basically navigational. There are two contests actually. The first one is the easy one. You just have to go from one end of the course to the other end and back autonomously. The other one is similar, but it is T shaped (requiring just a little more navigational skill), and also, there is a bonus for picking up cans or tennis balls. You can see the rules for the last contest that was in March at: http://www.dprg.org/contest.html . September's contest rules will likely change only slightly.

I think they should carry water into space, and use this LASER propulsion to get into orbit. Once up there, extend solar panels and use electrolysis to make hydrogen and oxygen for fuel.

I would like to know > what everybody thinks of these two options. Merlock, I use the Dallas 80C320 part, and it is very nice. The part is very fast, and can operate many peripherals at one time. My robot GeneSys-1 is powered entirely by this one processor, and so far there has been no problems with horse power. However, I'm big on C and C++, and thus my search for an MPU solution would very much hinge on availability of good compilers and development tools. I'm using an older Archimedes C compiler that works very well with the 80C320. I don't know who has got the best compiler product now. However, these things tend to cost quite a bit ! I recently did a full evaluation on the Philips XA CPU, which is very similar to the 8032 but has a 16 bit processor instead of an 8 bit processor. I found the CPU to be pretty nice, but it did have a couple of flaws. First of all, the Dallas has 6 external interrupts, and that's nice for robotics! The XA only kept the original two. The XA will only do16-bit reads and writes to even memory locations.... this may not be so bad for robotics, but was a nightmare for my day job applications of communications! After searching for compilers, we found the "Tasking" compiler to be best. The XA can run circles around the 80C320 when it comes to math (10x improvement) and memory moves (3x improvement). The 80C320 is still faster at I/O and bit operations. I heard Dallas is coming out with an 8032 like part that can access beyond 64K very soon. As I understand it, it's still an 8-bit part, but it has provisions for expanded memory architecture. You might want to look for the new part on their web pages.

Using the PLD's would also be great for sensor interface, signal conditioning, memory, Neural Networks or anything else you can think up. I ordered both boards for $249 with a student discount (I can buy a lot of Ramen noodles with the extra $).

It's not so hard to convert a simple lawnmower engine to run off water (it would use magnetrons to convert a small amount of water into steam, which would drive the pistons instead of a gasoline explosion). The problem with (conventional) electrolysis is that it takes a lot of current (several amps) to do anything usefull. And at that, the water has to have some kind of acid added. I did read about this thing called the Meyer cell, that supposedly uses only about 500mA of power and works best on pure water.. but I won't go into detail on this list. After all, it's for robots...

I did a little looking and found some info about Meyer's cell. The primary difference is that it works on high voltage rather than high current. The higher voltage basically ionizes the water and a very high "local" current flows and electrolyses the water. This way, you don't have to add chemicals to make the water conduct a high enough current to electrolyse. I can't think of any ways to generate high voltage except by methods which draw high current, so overall efficiency would still suffer. It's still very intriguing, though...

If you're making a robot that's trying to be human, you'll need to know these. Here's the URL: http://www.abcnews.com/sections/science/DailyNews/desires980616.html I once talked about making an AI using the want (or desire) principle. Someone went and did all the work to find out the different desires we humans have. I really doubt that this is a complete list like they claim. Curiosity: desire to learn Food: desire to eat Honor: (morality) desire to behave in accordance with a code of conduct Rejection: fear of social rejection Sex: desire for sexual behavior and fantasies Physical exercise: desire for physical activity Order: desired amount of organization in daily life Independence: desire to make own decisions Vengeance: desire to retaliate when offended Social contact: desire to be in the company of others Family: desire to spend time with own family Social prestige: desire for prestige and positive attention Aversive sensations: aversion to pain and anxiety Citizenship: desire for public service and social justice Power: desire to influence people Jim's additions: =============== Survival: desire to survive. (Can't believe they missed this one!) Dontawannawork: desire to play hookie as much as possible. WishIwereamillionaire: desire to have loads of money, cause I ain't got none. HomerSimpson: desire to have chocolate and doughnuts. ...mmmm chooocooolaaate. NotCriogenics: desire to live forever (yet not in a frozen state). (Maybe this should be called Fame: I wanna live forever!) IWannaSeeTheGrandKids: a desire that grows as you get older. NotInMixedCompany: desires that are better left unsaid. BetterThanJackInTheBox: desire to go to a fancy resturant once in a while. UggIshtarOrLeonardPartSeven: desire to pick a descent movie and be able to find a baby sitter once in a while. DontaWannaMow: desire to pay to let someone else mow the lawn, but wife insists I do it. Great Opportunity for a robotics project. Rhythm: desire to know when to tap your toe. I've got good looks, I've got rhythm... who can ask for anything more. Funny Bone: desire to tell a joke that people will find humorous. - - - ____ - - - - - - ___ - - - - - - - - - - - - - - - - - - - - - - - - - - \/\_\@ ____ / /\ __ ___ ___ http://www.dprg.org 06-20 / / /\ / / /\ /--/ //\_\/\_/\ /\/\/\ /\_/\ jbrown@cyberramp.net /__/ / / // / / / /__/ // / /__/ //_/_/ // // / (972)519-2868, (972)495-3821 \__\/ \/ \/\/\/ \__\/ \/ \__\/ \_\_\/ \/ \/ jgbrown@spdmail.spd.dsccc.com http://www.cyberramp.net/~jbrown www.geocities.com/TimesSquare/Castle/6818 ------------------------------ From paul at geeky1.ebtech.net Wed Jun 17 06:58:42 1998 From: paul at geeky1.ebtech.net (Paul Anderson) Date: Thu Feb 15 16:50:52 2007 Subject: DPRG: Ongoing search equals more dumb questions Message-ID: On Tue, 16 Jun 1998, Merlock Ambriousis wrote: > > I tried the link, it seemed to be down......will try it again later. > May have a place that is local to here that sells them.....they were > closed when I called them.....will try again tomorrow > Perhaps he meant www.questlink.com - --- Paul Anderson - Self-employed Megalomaniac paul@geeky1.ebtech.net "Mr. Checkov, are you aware of a radiation surge eminating from our ship?"

I've been doing quite a lot of passive research and semi-active PCB designing. I've put three dedicated motion control chips in three different designs. So far, the National LM629 is my favorite, largely because they are relatively cheap. My big question marks have been issues dealing with interfacing two such chips to the data and address buses of my controller. JKMicro (the controller manufacturer) has provided some kinda generic help, but anybody's input here would be way cool. In my research, I found that STMicroelectronics (formerly SGS-Thompson), has a BUNCH of microcontrollers with various "application specific" I/O configurations, including a 32 bit part with about a dozen PWM outputs (for video monitors), a dedicated GPS processor, and dozens of parts geared towards automotive applications (door locks, engine control, air conditioning control, etc). Many of the automotive control parts had inputs that debounce contacts for you, ADCs, 2A H-bridge outputs and EEPROM. It was fun research and I could not stop coming up with ideas! I ordered data book CDs from Texas Instruments. That has helped a lot in doing pinouts of various chips. I've downloaded about 30MB of .pdf files, mostly for Hewlett-Packard, STMicroelectronics and National Semiconductor motion controllers and support chips, applications notes, etc. >From Microchip, I found a servo motor controller implemented on a PIC17C42. It is a pretty serious servo (the application "note" is 142 pages!) with PWM, incremental encoders, trapazoidal movement profiles, etc, and there is still some I/O and processing power left over for another application! All operational theory is revealed with nice clear explanations, so the concepts may be applied elsewhere. It might be time to roll my own... As for actually getting ready for the contest, I have begun clearing the workbench at home. That room gets used for storage a lot and I've been working on various PC projects, so there is no room to work on the bot, and this simply will not do! I need to make sure the 'bot's batteries are up and running. They haven't been charged in a while. Even after all this research, I still don't have any kind of proximity detection. At least short term, I think I will try the ultrasonic using a hacked Sharp IR detector. Parts count is real low and software should be "easy". We'll see.....

I don't want to hurt anybody's feelings, but it is clear from your rhetoric that your brain has been overloaded while in college and you no longer can grasp reality. This is another example of university space and time being wasted. Some mentalities just can't handle that much education. I guess it's ok to dream, but NOT ON THIS LIST PLEASE! Too many degrees, not enough common sense! We are Robot Builders NOT dreamers, although we dream ahead a little at a time. If we spent our time dreaming as far ahead as you do, we would be merely wispy energy nodes (CORE processors?) floating through the galaxy blown by the ion winds of whatever star happened to be near. - -- _ _ / || \ Regards, Alan Bredon / || \ My views & opinions do not represent my employer. /. .||. .\ "PC means Personal Computer, Political Correctness /-|-||||-|-\ will not be tolerated." _|_|__|_|_ http://www.imagin.net/~abredon/robot.htm | . . . . | And always remember to ESCHEW OBFUSCATION! |__________| ------------------------------ From ditto at getonthe.net Wed Jun 17 21:32:02 1998 From: ditto at getonthe.net (Jeffrey T.

Compared to the time and energy involved in writing the code, and the cost of the other components for the robots, the processor cost seems to be in the noise. I will probably end up going with something I can wire fast. I can do a lot of stuff at work for ARM and 8032 and have some ASICs that would be cool for robotics based on these cores. The ARM core is probably a bit ambitious for September. I have found Forths for every processor I am considering. I have always liked Forth as a bring-up tool and hope to have something working soon.

I should have worded my statement a little more clearly. I was speaking not of whether it can be done but the efficiency, or of more interest to my needs, the size at which it can be done. The site covering the Meyer cell indicated that they were using 10,000 volts at "milliamp" levels. Since they were a little vague, I'll assume we need 10mA. Unless my math is off by an order or two of magnitude, to generate 10,000 volts at 10mA (100 watts) from a 9 volt battery requires over 11A at 100% efficiency, which is not really achievable. Off the cuff, I'd say that one would have to plan on providing 16A, assuming about 70% efficiency (reasonable for a hobbyist). Where the Meyer cell concept begins to shine is when you have a readily available high voltage supply. Even running a 10KV 10mA generator from USA mains gets the current draw down to very managable 1.6A or so. A really efficient rectifier running on three phase power could probably get the requirements down around 1.2A, though at a substantial cost. Of course, the cost of extracting natural gas, conversion loss from natural gas to electric power, transmission loss getting it to the premises, more conversion loss in the transformer on the pole and in the power supply before electrolysing the water (still not a 100% efficient process), fuel loss in the recovery process and conversion losses when burning the generated fuel, even in a fuel cell, all add up to make one wonder why they should even try! :) Robert (the overly verbose sometimes) ------------------------------ From jkoenig at netgazer.net Sat Jun 20 19:33:12 1998 From: jkoenig at netgazer.net (Jeff Koenig) Date: Thu Feb 15 16:50:52 2007 Subject: DPRG: Anyone missing anything?

It would be better if we could do this more often. Also, some people can't attend meetings and miss this very important part of each meeting. We also have out-of-town members who miss it. I would like to propose the following solution: MPUT - Member Project Update Text Members could go to dprg.org and login to the MPUT form where they could enter their membercode and a short chunck of text updating the rest of us on their project. This would include info such as problems, part suppliers, ideas, etc. The form would have 3 fields: membercode, subject, text. When submitted, the form information would be added to the top of the members MPUT web page. A link on the DPRGs home page would allow everyone to access the MPUT pages by selecting a member name. Along side of each member name would be the subject field of the last entered submission. Information in the MPUT system would accumulate allowing future robot builders to browse for hints.

Micro Farads is really uFd where the "u" is a greek micro (hard to make for email). We also use mFd for it's sound and pFd for pico Farads. Some meters read out in nano Farads, (which I avoid).

It's part of my encoded modified servo. http://alias.flash.net/users/slugmusk/servo.htm Hewlett-Packard makes a clear 8 pin chip (HEDR-8000) for reflective encoding that outputs a nice TTL quadrature, but it requires a code wheel with a minimum of about 60% specular reflectivity. I am thinking of turning one from aluminum, polishing it then placing the stripes on it, or printing the stripes on tranparency and affixing that to the polished wheel. I may also turn one from a discarded CD (that AOL distribution should do nicely) and apply the transparancy to that.

As it is, it's already functioning as well as it ran in the last contest in March. I plan to rewrite the software a little to make it navigate more reliably. Maybe it will finish on the first run this time??? If time permits, I may try to make a gripper mechanism, but I'm not pushing for this yet. Actually, with this robot, I keep telling my wife I'll put a vacuum cleaner on it and make it vacuum the living room, so I may have it attached for the contest (not that it'll matter). I may change the motor driver control from two mosfets to our l298 board. Baby Bot II: This was the robot based on the richochet racer chassis. As it is, it would not take much to get this robot running as well as it did in the May 97 contest. I may try to get this robot actually be able to complete the course this time. It will likely have a sonar on it this time. Baby Bot III: This was the walker/dragger robot that couldn't walk backward well. It was constructed with very much hotglue. One day I left it in the back seat of my car, and it melted and fell apart. :-( (Barry will love that one I'm sure). Anyway, I have the technology, I can rebuild him - that's the real beauty of hotglue. I plan on removing the head, and reusing the servo for sonar directioning. It still won't be able to walk backward very well, but I'm hoping it can make a turn well enough to avoid the walls, and walk back on it's own. I will likely replace the plastic resin parts with something else, probably wood. If I can get these three robots upgraded and working satisfactorily, I may try to build some new bots. Premie Bot: This robot will be using the modified micro servos. I don't know what it will look like yet except that I hope it will be small (3" cube or 4" cube). Rockin Robin (name may change): I'm thinking of making a biped walker robot that will make use of 4 servos. It will have two parallelagram legs each controlled by one servo. Then it will have a weight mechanism for x & y weight for throwing the weight forward and backward, and left and right. It will basically throw it's weight to the left to rock over to the left left. Throw the right leg forward, then rock over to the right leg. It will also need to rock forward and backward for this to work. If I feel confident enough about the weight balancing movement, I may try to add some sort of tilt sensors (mercury at first?) and try to make this more of a balancing robot like a mushroom or inverted broom stick with two legs. I may put a sonar on this one too and add another servo to direct it (I'm very pleased with the sonar on the Darth robot). Some other Slow Bots (I've got the parts, if only I had the time): Some other cheezy bots using some cheap 30rpm motors I bought. I may forego these and try to build a gripper for one of the other bots. I guess I really don't care if I place in the top 3 of the contest with the best time, I'm just shooting for robots that can _complete_ the contest. If I can have more than one robot ready to compete that's all the more thrill I will have. I'm trying to have a variety so that I can try out many different designs. So far I've been having lots of joy from building them. - - - ____ - - - - - ___ - - - - - - - - - - - - - - - - - - - - - - - - - \/\_\@ ____ / /\ __ ___ ___ http://www.dprg.org (July18) / //\ / / /\ /--/ //\_\/\_/\ /\/\/\ /\_/\ jbrown@cyberramp.net /__/ // // / / //__/ // / /__/ //_/_/ // // /(972)519-2868, (972)495-3821 \__\/ \/ \/\/\/ \__\/ \/ \__\/ \_\_\/ \/ \/jgbrown@spdmail.spd.dsccc.com http://www.cyberramp.net/~jbrown www.geocities.com/TimesSquare/Castle/6818 My employer won't claim these opinions so I'm giving them away for free. ------------------------------ From barry_jordan at email.msn.com Mon Jun 22 12:34:05 1998 From: barry_jordan at email.msn.com (barry jordan) Date: Thu Feb 15 16:50:52 2007 Subject: DPRG: Encoder wheels Message-ID: Bill James wrote: I was wondering if anyone has made encoder wheels that are used in conjuction with a u shaped ir emitter reciever pair.

Nope, but I think it's probably ok. I was thinking of trying to get it into easytrax and doing the easytrax2ps program so that we know it's right. It's hard to design something knowing you have to reverse it and flip it, and do it backward and hoping the pins are all on the right side. I'll try to do it and get it to you in the next couple of days.

I hope you are doing well. Stepper motors depend on the driver circuitry that you are using. There are a couple of ways to hook up a stepper motor: UCN5804, or ULN2804. The 5804 uses step and direction, whereas the 2804 is just a darlington array where you just sequence the 4 lines. Here is some sample 8051 code: ; ÚÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄ¿ ; ³ turn_motor1(a) ³ rotate the first motor ; ÀÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÄÙ ; example: ; mov a,#200 ; 200 steps ; acall turn_motor1 tm1: push acc tm1_top: push acc mov a, mot1 ; select next pin rl a and a, #15 jnz tm1_noreset ; do we need to select pin 1 again mov a, #1 tm1_noreset: mov mot1, a ; echo changes to p1 not a mov p1, a pop acc push acc ; sleep for a tick mov a, speed acall pause pop acc djnz acc,tm1_top ; loop clr a ; stop all motors not a mov p1, a pop acc ret ; return - - - ____ - - - - - - ___ - - - - - - - - - - - - - - - - - - - - - - - - - - \/\_\@ ____ / /\ __ ___ ___ http://www.dprg.org 06-20 / / /\ / / /\ /--/ //\_\/\_/\ /\/\/\ /\_/\ jbrown@cyberramp.net /__/ / / // / / / /__/ // / /__/ //_/_/ // // / (972)519-2868, (972)495-3821 \__\/ \/ \/\/\/ \__\/ \/ \__\/ \_\_\/ \/ \/ jgbrown@spdmail.spd.dsccc.com http://www.cyberramp.net/~jbrown www.geocities.com/TimesSquare/Castle/6818 ------------------------------ From jbrown at cyberramp.net Mon Jun 22 21:30:55 1998 From: jbrown at cyberramp.net (Jim Brown) Date: Thu Feb 15 16:50:53 2007 Subject: DPRG: Re: DPRG Meeting Message-ID: At 08:49 PM 6/19/98 -0700, you wrote: >Hi... > >When is the next DPRG meeting at the Infomart?

Chemicals. The 600 series board worked great and the two 500 series boards didn't. M.G. Chemicals webpage (www.mgchemicals.com) shows that the 500 series boards are plain copper, but I had called tech support and they said that some older boards in the 500 series were presensitize. The boards in the 500 series that we purchased were in black plastic bags just like the 600 series, in fact, someone had taken a pen and marked-up the 509 number to read 609, and on all of the stock/inventory stickers they had 609 written on them. The type of photoresist on the 509 boards was a brownish-transparent film which requires perfect timing and handling to develop and etch. The 600 series boards have a dark green opaque photoresist which is covered by a piece of white plastic that has to be peeled off before exposure. We used Ammonium Persulfate for etching, and it took forever. I believe it took so long because we didn't heat it up. Also, I've heard that Ammonium Persulfate quits working when it gets saturated; one minute its working, the next its not. Ferric Chloride is the other chemical used for etching. It is dark brown (Ammonium Persulfate is clear), so you can't see the board while it is etching, but its etching capability dies down gradually. Both etchants can be stored and reused again.

Maybe someone else could answer them better. > On the subject of PC board etching, I have a few questions: > > 1. What effect, if any, is there if the board is over exposed and how > severely? Light seeps through the black toner at a certain rate. What you want to do is expose it enough so that the clear part is exposed all the way, but the black traces are not exposed enough to matter when the developer hits it. What will happen is too much exposure will let enough light through the black traces to expose the black part too so that all of the board is exposed and all would get eaten away by the developer. Some people double the design (two copies of the design on top of each other) to get a better black (less light gets through). However, after 20 minutes or so of exposure, there's probably no significant difference in the effectiveness of the now _un-sensitized_ board. :-) At some point, overexposure has a limit in that your light bulb would sooner or later burn out. :-) I suppose you could always buy another bulb and continue to overexpose the board. :-) > 2. Does the non-point-source nature of a flourescent tube cause the traces > to be narrower than they should be? yes. You want to get the design as close to the board as possible to minimize the light getting under the design. Get the light away from the board, though, and it takes longer to expose it, or get it too close, and more light gets under the design. 6" to 12" is probably ok. > 3.

Ammoniapersulfate or Ferric Chloride is ok. > 5. If I wanted to do this on my own, what items would I need to have? Light source, non-UV-reflective glass to hold down the design, presensitized boards, a design on transparency, developer, etchant, tray for dipping the board in the developer, tray for dipping the board in the etchant, and optionally Tinnit to tin the traces.

Then more of the "unexposed" sensitizer gets exposed thru the black art and will be partially or completely removed by the developer which results in "swiss cheese" copper or no copper. > 2. Does the non-point-source nature of a flourescent tube cause the traces > to be narrower than they should be? The art is exposed emulsion-side down (face down) directly contacting the PCB and when tightly held in a print frame, the effects of the light diffusion becomes less significant. The important thing is to maintain an even amount of light over the entire panel to provide even exposure. > 3. Could timed exposure to sunlight also transfer a pattern? Yes, BUT: HOT, variable, windy, DUSTY, bugs, etc. > 4. Are different etchants used for different photo sensitizing methods? Most are compatible with the Ammonium (or is it Aluminum?) Persulfate and Ferric Chloride. The different sensitizers may need different developers, although I'm only familiar with one for hobby. It should be noted that there are sensitizers for Negative art and for Positive art. The Positive art is where the traces are black and the spaces are clear, and is the most common for hobbyists. > 5. If I wanted to do this on my own, what items would I need to have? Pre-sensitized PCB, Artwork, Print Frame, Exposure light, some way to mount the light a specified distance from the print frame, Developing tray, Developer, Etching tray, Etchant, Tongs, Drill press, Drill bits, Fine steel wool (optional), "Tinnit" Electroless tinning kit (optional), hot water, timer, Exacto-knife, scissors.

They can be scraped off the art with an Exacto-knife. > 8. How tough is it to align traces for a double sided board? Cut the art accurately along the crop marks. Verify the top and bottom art registers to each other. Mark the protective film on one side of the PCB to show which end is the top. Do not remove this film yet. Remove the film from the other side of the PCB. Apply the solder-side art to the PCB, face down, aligning the top corner of the art with the top corner of the PCB. Expose. Remove the film from the remaining side of the PCB keeping track of the TOP. Apply the component-side art to the PCB, face down, aligning the top corner of the art with the top corner of the PCB.

The MG Chemicals site did not really go into much detail in the differences between these two. From what I can see, you might have better luck in the long run with ferric chloride because it seems friendlier to the user, being premixed and with a long life. I wonder how the prices compare? They also say that you can indeed expose your boards with sunlight or maybe even regular flourescent bulbs, but without a photometer with a UV filter on it, you are in total WAG land as for exposure times.

MSWord98 will generate a new phrase: "In need of Viagra" For those who don't have Word, what has happened here is that the thesaurus (Shift F7) generates phrases as suggestions when it doesn't find a match. In this case, 'unable to follow directions' generated the phrase 'unable to have an erection' Before everyone jumps off and assumes that some turd at Microsoft is trying to be mischievous, there is a logical explanation. If you do a little more digging, you will find that 'sexually inadequate' is the thesaurus entry that contains 'unable to have an erection'. Word used the key phrase 'unable to' to find all other matches. The other choices are 'unable to hear' and 'unable to distinguish sound'.

When you bring the trigger high, it sends out a ping and activates listining on the echo line. When it receives an echo, you can twiddle a line to reset echo (BLNK) to continue listening again. I suppose you could use that ability to listen for pings from other sonars and continue to do that forever. So, I guess the procedure could be something like this: Lets say you have two sonars, one for transmit pinging, and one for listening. 1. trigger listening sonar for a dummy ping to get it in echo listening mode (INIT). 2. after a time raise the line on the listening sonar that resets the echo to listen mode again (BLNK). 3. Ping the transmit sonar (INIT), and wait for the echo to go high on the other listening sonar (ECHO). (at this point, you have a distance/time measurement). 4. Wait a while for echos to go away (100ms?). 5. Reset the transmit sonar (INIT), but on the listening sonar, just reset the echo line again (BLNK). 6. goto step 3. - - - ____ - - - - - ___ - - - - - - - - - - - - - - - - - - - - - - - - - \/\_\@ ____ / /\ __ ___ ___ http://www.dprg.org (July18) / //\ / / /\ /--/ //\_\/\_/\ /\/\/\ /\_/\ jbrown@cyberramp.net /__/ // // / / //__/ // / /__/ //_/_/ // // /(972)519-2868, (972)495-3821 \__\/ \/ \/\/\/ \__\/ \/ \__\/ \_\_\/ \/ \/jgbrown@spdmail.spd.dsccc.com http://www.cyberramp.net/~jbrown www.geocities.com/TimesSquare/Castle/6818 My employer won't claim these opinions so I'm giving them away for free. ------------------------------ From droid at bellatlantic.net Tue Jun 23 22:13:54 1998 From: droid at bellatlantic.net (Cyborg) Date: Thu Feb 15 16:50:53 2007 Subject: DPRG: 8051/ 8031 Message-ID: As I'm looking at the posts from this year, I have realized that this group is 8051 / 8031 microcontroller oriented.

It has 128 bytes of internal ram. It can access 64k external EPROM AND 64k external RAM for a total of 128k. It has 2 16bit timers, and can be configured to split one of the 16bit timers to two 8bit timers giving you 3 timers. 8051 is the original. It has 4k of ROM. It can only be mask programmed at the factory. If you find one, you can tie line 7 low so that it will ignore the ROM and access external memory (effectively turning it into an 8031). 8052/8032 is the same, but has another timer and has 256 bytes of internal ram. 8751 is the EPROM version (87xx) of the 8051 (don't tie line 7 low). 89C2051 is Atmel's Flash (89xx) 20pin version. You can go to the Philips' site, and order a data book of all of their variants, they have loads of varients!!! 20 pin devices, some with A/D, some with more timers, some with many pins of I/O (something like 5 or 6 ports, ie: 40 or 48 bits of i/o or more) etc etc. - - - ____ - - - - - - ___ - - - - - - - - - - - - - - - - - - - - - - - - - - \/\_\@ ____ / /\ __ ___ ___ http://www.dprg.org 07-18 / / /\ / / /\ /--/ //\_\/\_/\ /\/\/\ /\_/\ jbrown@cyberramp.net /__/ / / // / / / /__/ // / /__/ //_/_/ // // / (972)519-2868, (972)495-3821 \__\/ \/ \/\/\/ \__\/ \/ \__\/ \_\_\/ \/ \/ jgbrown@spdmail.spd.dsccc.com http://www.cyberramp.net/~jbrown www.geocities.com/TimesSquare/Castle/6818 ------------------------------ From w-james2 at ti.com Wed Jun 24 10:18:14 1998 From: w-james2 at ti.com (Bill James) Date: Thu Feb 15 16:50:53 2007 Subject: DPRG: Thanks Barry Message-ID: I just wanted to thank Barry publicly for his help and use of the tools last night.

For us there is no difference between the 8031 and 8051 because we can not use the ROM memory, and we do not have the volume to justify the factory programming the ROM. Later the chips were upgraded to CMOS and they added the C in the middle of the number e.g. 80C51 and 80C31.

And have fun exploring! > Try searching for the microcontroller faq for starters. > I will tend to disagree that the group is 8051 oriented. I know Jim and I are big 8051 users. And since we post a lot, you may get that impression. But I think there are more 68HC11 users in the club. At the last meeting there were more PIC users than I have ever seen in one place. I think three or four of the new members were going to use PICs. A couple guys were planning to use the Atmel RISC processor. I think Wade was using a Motorola MC68332. Finally, a number of us are looking at using old PC boards for our next versions. The only reason I am using the 8051 is that like me, it is an old chip. :) And I just knew more about it. I used it at TI, and NewMicros sold a working board for $39-$49 with an assembler and C compiler. (I have purchased 3.) It also has more varients, like the 80C51FA with PWM built in. The newer processors are often faster. But for most of what I need to do this is fast enough. If it is not, I can switch to something else, and in my case, this will probably be something PC based. The other thing to consider, if you don't already have a preference, is what are other people using? A benefit of the club is that if there are other people using the same processor or board, you have someone to talk to if you have a problem. If you choose to use the Hatachi RISC processor, for example, I don't think anyone in the club can help you if you have a processor specific problem. ------------------------------ From rten at polaris.nstar.net Wed Jun 24 09:03:28 1998 From: rten at polaris.nstar.net (Ralph Tenny) Date: Thu Feb 15 16:50:53 2007 Subject: DPRG: 8051/ 8031 Message-ID: Kip: Also please be aware that the 80C52AH is also available with a very good industrial BASIC on-chip.

Judging from your post, it sounds a little like you have never been to tanners. Let me tell you, It's a playground for us types there. You will find 95% of the parts you need to build just about anything. Forget parts numbers though. Most of the items are surplus. They will have data sheets you can borrow and run get copied next door for such things as Sharp detectors and LCD, etc.. BTY, Thanks for the Aluminum and Sunglasses.

Did yall make the latest H-Bridge board, or the one yall made for me? If it's the old one, the trick is that everything needs to be put on the copper side. It's a little tricky. :-( I've soldered the components on my, but I haven't had time to test it out yet. I still have to solder on a terminal block that hasn't come in the mail yet. Was th
