The following instructions detail how to build a Solar Power Smart Head version 3. The Head will seek light and when it finds the brightest source it will go into a low current standby mode. This version also comes with an low power FLED circuit to indicate when the head is active.
Wot?!? New gear motors?

October 31, 2008
Hey, how about that! We've got some new gear motors to complement the popular Mini Metal Gear Motors (the GM11a, GM12a, GM13a, GM14a, GM18 and yes, even the mutant GM19).
What's particularly new is that they have sealed cylindrical gearboxes! Same sort of gearing, but no funky rectangular shape - just a nice, sleek, clean enclosed gearbox. And these new motors aren't just sealed-versions of their brethren - they actually bring new performance characteristics to the party. Particularly torque. We're talking some finger-breaking torque in a tiny package (ok - if they don't break your finger, they'll cause considerable discomfort...). Sooo, your actuating-enjoyment, we present to you the:
GM20 - Sealed gear box, with performance between the GM11a and GM12a
GM21 - A longer, sealed gear motor, but a real torquemeister (yes, I said torquemeister), with over 100in*oz of torque @ 6V
GM22 - Another sealed gear motor, with more torque than a GM14. Good Turbot tumbling robot type motor!
We love little precision gear motors. They're just so cool...
