creating movement- pulsed coil magnet? other ideas? and how to accomplish? Answered
I'm wanting to swing a small pendulum around (randomly would be nice). I'm figuring something like is inside this candle would be the best method:
However, I don't know where to buy or how to make this (I can make a wire coil, but not program a chip to turn power to it on and off). The candles are too expensive to buy to take apart. Does anywhere happen to sell just that piece? It would be great if I could just buy it, hook it to my 3v power, and I'm all done.
Or does anyone have other ideas?
