<DIV><FONT face=Arial color=#0000ff size=2><SPAN class=068225315-11072008>I have
been working on and off (mostly off) on hacking a Stanly Fat Max laser range
finder (got it from Home Depot for $99). The laser range finder module is
from Leica and is attached via ribbon to a pcb with a microcontroller of some
sort that takes care of button presses, area calcs, LCD display and interraction
with the range finding module. I have not been able to find the
interface documentation anywhere and calls to Leica came up empty. Anyway,
I am making a small pcb that allows me to connect the laser module with a
MEGA128. Meanwhile, I have monitored and documented all of signals on the
connector to the module during operation and have SOME idea what SOME of it
means. Once I complete my board, I will be able to figure out the rest.
I'll post a complete project on the SHARPBots site.</SPAN></FONT></DIV>

Wow, time of flight of a photon, that is pretty fast electronics. Why
not get a fancier laser that really emits in one wavelength and one phase and
fire it continiously. Look for the phase shift as the indication of
distance rather then trying to time the flight of a photon. The tradeoff
is you will need a fancier laser that has controlled phase. This is the
idea behind the laser bugs. They shine a laser on a window and monitor
the small movements of the window caused by talking by monitoring the phase
shift of the reflected signal.<BR><BR> Just another high dollar complex
project to implement. :)<BR><BR>John Drummond<BR><BR><BR>-----Original

you I am not aware of any commercial-off-the-shelf logic device that operates
at 1 GHz (1 picosecond period). <BR> <BR>In the realm of
programmable logic, the (fastest, I think) Altera Stratix has a 600 MHz core
clock. <BR> <BR>The closest thing I can think of is a specialized
high-speed processor, like the PowerPC 460GT from AMCC. However, I don't see
any Timer peripherals, either some serious hacking is in order; or it may not
even be possible with this device. <BR> <BR>These guys make laser
range finders: <BR><A href="http://www.opti-logic.com/"

says: "Less expensive models around 100$/ˆ are emerging from Bosch with the

Ray <BR>> <BR>> <BR>> Dean,Good point on Ray's
project. <BR>> <BR>> I guess the question is to find out what
you are trying to do, Ray. <BR>> <BR>> <BR>> That is,

talking an advanced project where specialized hardware/ > knowledge might
be needed. <BR>> <BR>> <BR>> Reference designs are a
good place to start. <BR>> <BR>> <BR>> Yeah,
breadboarding in this range would be
out. <BR>> <BR>> <BR>> Might suggest playing with
sonar first. You will learn a good deal > and sound's propagation rate is 1
millionth the speed of light. > Master that first. Just Me
