Solar Head
This is my third attempt at a solar head, again using a Nihon gear motor like my second one. I was trying to improve the aesthetic, as well as experimenting with the Power Smart Head Version 3 circuit. I couldn’t get the latching SE to work very well in that circuit, so I modified the circuit to use a standard Miller solar engine, and was thus able to use the spare inverters to help drive the motor.
Unfortunately, this beast needs very bright light to work well, so it needs direct sunlight to perform at its best. I might try it with a lower voltage trigger at some point.
