I wanted to create a wireless lamp that more people would be able to print with smaller printers. This runs a motorcycle tail light (Sylvania 90, 12V, ~6W). I chose this bulb because of it's size and voltage requirement and I had some lying around. It would probably work better with a 6V bulb but I didn't have any.
Resonant Frequency: 6.5MHz Spiral Inductor: ~0.1uH. Overal Dimensions: 2.3" x 2.3" x 3"
