PendulumBot SunSwinger Schematic

SunSwinger schmatic from

Circuit used: SunSwinger
Construction Notes:
I built this pretty much to the schematic. I purchased the magbot coil from I free-formed the circuit and used brass tube for the frame. The bar magnet is a 1/8' x 1/4" neodymium magnet. I mounted my magnet on the end of a brass wire, but you could have just as easily used a piece of fishing line. One thing to note is that the LED is reverse biased in the schematic. This is correct. You could replace the LED with a diode and a high-voltage capacitor and put the back-EMF to work. I would suggest downloading the PDF from or ordering the kit.
