A beamant is a phototrophic or photophobic bot that
can reverse away from obstacles.. Set up the
photodiodes and the touch sensors just like you would
a photopopper.
Basically that's it. Breadboard the circuit and test
it out for yourself and see what it does.

Ahh! Great idea Ian! Seven segment type numerical LCDs say from a broken digital clock or calculator. If you are lucky
and the letters of your name can be "expressed" in seven segments then you can use this display ( "W" is a problem!) .
Power consumption is virtually zero so it can be powered from 2 button cells for a couple of years. For a brighter but
power hungry display that requires no bicore you can use the LED seven segment displays but these do require resistors to
limit the current. (hey, laying a single seven seg display on it's side can display a "W" !) The attached shows a typical
seven segment display. Connect the common "backplane" and the unused segment terminals to one output of the bicore.
Connect the other segment terminals to the other bicore output. Make sure you connect all unused bicore chip input pins
to ground or you'll drain the battery. Just for starters : next let's use the HC240 tristate function pins to flash 2
different messages!

I just posted another video (in AVI and MOV format) to our website. A bit
large (+10meg), but is over a minute of Mark's latest Unibug BEAMants.
Worth a view.
Gone for the long thanksgiving weekend here in Canada (sorry didn't have
time to compress these files further). Back Tuesday.

Olympics? I can't find any future schedules or postings. I would love to
enter some bots into the competition, probably by proxy. I can't make the
trip, but I can ship the little buggers to someone who can go. If anyone out
there has any reliable info, let me know.
See ya,
Jim
