Subject: [alt-beam] Feed Back

I was just looking at BENDER a 1DOF light seeking head and I got an idea!!
We use IR. detectors to make our bots photo tropic right? And we tend to u=
se visible light emitting diode to indicate the direction of the light sour=
ce for our own amusement. So what if we positioned an IR emitter @ 90=B0 t=
o the receiver and place a first surface mirror (polished metal) at 45=B0 b=
etween the two and wired it to a) Positively feed back into itself or
b) Negatively feed back into itself
Recently there was a thread on how to add feed back to a walker circuit, th=
is would work it would, however ad a level of complexity that may be undesi=
rable. =
Maybe one of you speed builders out there could tryout and let me know what=
happens!! Today I am busily trying to finish the construction of a 17foot=
long canoe that was started last Oct!! I want to get it ready for Canada =
day.
