Are you planning on judging the last contest anytime soon? Istill very interested to see all the contestants (the robots, that is - I don't care about the people! ;-)

You'll get no flames from me... I like the idea...

OK, now there are 5 different ideas. From Richard Caudle, the 5th one (I
should have known this would come up):
Circuit-on-a-chip: A common beam Nervous Net, completely contained
on a small circuit board. PURPOSE: build prototype robots that
use a standard configuration. Allows builder to experiment on
mechanics without spending a lot of time assembly basic circuitry.

I had intended this term more for the fundamental component blocks (e.g.
a single Nv block, a single driver block, etc) rather than for a
complete circuit that happens to fit in a block. Ah well, it wouldn't be
BEAM if we didn't blur the lines in all our definitions :)

a 1F cap charged by a 5.5v solarbotics cell. 1n4148 diode. 74HC14 (i tried
it will the HCT too). and the led is hooked up to V+ and the output from
second inverter. after charging to 4v last night I set it solar cell face
down and it glowed for over an hour but very very dimmly. Any thoughts

nudge) and some stuff to make it with.
