The lightbox in my office could benefit from a geeky gadget decoration. The perpetual pendulum combines two things: a Random Oscillating Magnetic Pendulum (ROMP) and a solar engine.
With the solar engine, light strikes a solar cell, feeding voltage into a capacitor. Once the capacitor climbs to a certain voltage, a voltage trigger releases current into a cassette motor. The motor turns a striker that pushes the pendulum rod, pushing the ROMP into a swinging motion. Magnets at the bottom of the ROMP can be arranged to adjust the chaotic motion.
