I love the shaking idea, and I bet it would work great but I'm worried about the optics getting misaligned. Also our sphere is only 3.25 inches internal (with most being optics) and I'm not sure if we would have the room for that (but I might just try it out for fun). Back to my limits on inductive ...

Well I tried many different ratio's and everytime I needed to put the coils very close together to get any worth while signal out. I will then need to rectify the signal to get a DC and go through another diode to prevent the batteries from charging the solar cells. So in all I will have to waste at...

I'm using halogen lights to charge the batteries. The solar cells are at the bottom of the camera, and we are unable to point the camera upwards because it is self-righting. The best charging rate occurs when the lights are close to the solar cells so they get hot not because of the power being prod...

charging a battery without electrical connections

I'm working on a charging system inside an enclosed 4 inch sphere and wanted to get some feedback on some other ideas to test out. I tried inductive charging but it did not work too well and I believe requires the two coils to be very close together like the electric toothbrushes. I have used flexib...
