BUILD THE NYSTERY SOLAR POWERED PENDULUM

摘要

Powered using the energy of the sun, this solar pendulum does not require batteries or an electrical outlet to operate. So, how does the solar energy make the pendulum swing with no visible connections? It will have your family and friends guessing until you reveal the secrets of the electromagnetic coil and circuit hidden in the base. This device is a wonderful demonstration of clean, green solar power and is based on BEAM technology. It was inspired by the Magbot pendulum project in Dave Hrynkiw's book titled, junkbots, Bugbots & Bots On Wheels. When the solar cell is exposed to the sun or any bright light source, the pendulum will start to swing - almost magically.
