This is a pulsed pendulum of a special kind. The magnetic weight hangs on a sharp needle. It can move near frictionless around with the magnet poles in horizontal direction. The pendulum spins around the coil and around it's own axis. A 3V solar panel feeds the 10 Farad, 3V supercapacitor. A simple 2 transistor circuit is firing the coil as a magnet passes by. This pulse then repels the magnet. The very low power circuit uses only 15 uA on average.
