Hey RBNO Folks,
I will have some chili cooked up for this evenings RBNO.
I've got a IR LED Modulator that Dale built and some tuned sensors. Maybe we
can play with detecting beacon(s) on cones for upcoming spring conetest.
It appears the I must have wired up a receiver to filter pulse output from
sensors using simple RC circuits for use with analog input on microcontroller.
We should be able to hook it up to a scope and see what is going on.
I have some extra sensors and LEDs. Should have some Tiny13s laying around
somewhere.
Not sure if crystals would be needed. I see Dale put one on his modulator
which uses a tiny11. Was thinking could at least get a donkey to synthesize a
variable frequency pulse for LEDs (I know a 555 could do the same thing --
but where is the fun in that?)
The deal with using a microcontroller is to possible blink out unique
sequence for each cone.
I do also have some Sharp IR Distance sensors we could play with -- maybe
that would be better way for folks to go.
Ron
