It’s been a while since I’ve built any BEAM robots, but some wet weather prompted me to get back to the soldering iron and make a new bot. This is another solar powered “power-smart” head, built around a 74AC240 chip. The circuit is the Solar Power Smart Head circuit. The motor is a nice geared 141:1 MicroMo motor I got off Ebay. It has a cog attached to the spindle, which allowed me to mount it in a drilled-out hard drive part for the base. This guy fires every few seconds under bright light, and almost continuously in daylight, rotating quite quickly, and smoothly to point towards the brightest part of the environment. I’m pleased with it. permalink | robots | 2009.01.25-17:20.00 The Symet use one of the simplest BEAM circuits. The solar cell charges the capacitors (one or more in parallel). A solar engine circuit monitors the voltage, and when it trips power is dumped through the motor. Symets rest on their motor spindle, and scoot long the ground when the motor spins. When they hit
