I have been doing some BEAM bot work on the side. Nothing exciting but I wanted to keep making them to get some practice/experience for future projects with solar circuits. This is basically a replica of the solar spinner thats postedÂ here. It uses a Miller Solar Engine with a little modification.
Update: Added a timing capacitor (10uF) between pin 2 and 3 of the voltage trigger. Seems to work a lot better now.
