Inspired by the Ice Bulb published on Instructables, we decided to create our own version. Ice bulb suggests that we use a balloon to shape the ice and before it freezes, add an LED so that it can glow. Since we decided to use a whole bunch of LEDs (on a string), we opted to […]
Cool project
Dave Hrynkiw
January 12, 2003
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!
