PendulumBot SunSwinger Schematic

SunSwinger schmatic from

Circuit used: SunSwinger
Construction Notes:
This one is quite similar to the original PendululmBot. The only real difference is the form factor. The schematic is the same. 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' round neodymium magnet. I mounted my magnet on the end of a brass wire (with hot melt glue), 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.
