Here's a tip submitted by Rick Steenblik regarding hacking our SCC3733 for less voltage, but more current: After using your SCC3733 solar cells for a couple of bots I noticed that they can be altered to provide about 3.3v at 80ma (in full sun) by cutting the bus connector on the back to electrically separate […]
Cool project

Neil Sandstrom from the BEAM mailing list recently posted a notice about his "ShokHead" circuit built from our tutorial. What makes this project a bit different is that he mounted it on a VPM motor, so it's all self-contained. Here's what he says about it:
Just finished!!! Check it out it is really small!! http://groups.yahoo.com/group/beam/files/Psyclesam/ Uses all smd parts except Main Cap and PDs. Parts 1 x SB VPM vibrating disk motor 2 x SFH203PFA Photodiodes 1 x 74AC240 (SOIC) 2 x .22uF 16 Volt smd cap Miller SE... 1 x Panasonic BP2422 Solar Cell 1 x MN1382-J (smd) 1 x ZN2106G (SOT223) 1 x SB Small 1000uf cap 1 x TMMBAT42 (smd schottky diode) 1 x .22uF 16 Volt smd cap It turns a small amount but it does function well. Maybe a bigger cap like 3300uF in the next one. I temporarily gave up on Fled and Fred heads and opted for the very low part count and easy freeformability of the Solarbotics ShokPhoto Head Circuit. https://www.solarbotics.com/beam/circuits.asp Thanks SB!!!
He's also posted links to the videos of it here.
Due to bandwidth constrictions on his present server, we're mirroring the large video file here.
Nice job, Neil!

Small batteries!
We've come across a variety of small batteries that are splendid for the small types of robots we're used to building! A variety of 3.6V and 4.8V packs ranging from 50mA to 300mA capacity means we have something ideal for almost any battery-powered BEAM bot. Check them out in the "New Items" link under "Products", […]

We're still undergoing website bug-stomping. You may have noticed some changed news items and the like. One of the edits crashed the page, so we had to reload an older backup. The SCPD photodiodes are now officially sold out! KaPUT! Gone! Until we can find a reasonably priced replacement, we won't be restocking these items […]
