The BEAM Circuits Collection is a
Miscellaneous BEAM Circuits
What didn't fit
This section contains odd and interesting circuits I've run
across along the way.
- Charge pumps -- a charge
pump uses arrays of capacitors to increase voltage in a
circuit. In this way, you can drive higher voltage
loads from logic voltages of 3 - 5 volts.
- Battery chargers --
handy for non-solar BEAMbots
(particularly ones that use rechargeable batteries in
"non-standard" shapes and sizes)
- Sound generators -- if
makes sounds, it's a multi-sensory experience!
- Remote control -- a
more-direct way to make your BEAMbot
do what you want
- Radio frequency transmit /
recieve -- another way to communicate with your
(or enable groups of them to talk together)
- Solar cell simulators
-- mighty useful in testing and designing your 'bots
- Op-amp based Nv nets
-- a more complex, but more flexible way of implementing
bicores and quadcores and such.
And then, what doesn't even fit here:

Chiu-Yuan Fang maintains Rigter's
NuPages, an archive of articles by Wilf Rigter
(distinct from Wilf's own pages, the NuWEB).
Heretics (now defunct) used to have a lot of
good discussions on BEAM topics; also another
collection of Wilf Rigter's circuits (hopefully
both will return some day).
There's a British electronics club called 4QD
that has a good circuit archive here.
