This repo is for the Levitating Light project. With the aid of a couple of magnets, you can create a light that floats in the air without any wires connected to it.
Levitation Tips:
- Build the levitation circuit first and get that system stable before starting wireless power transfer.
- Use the potentiometer to adjust the levitation set point.
- Secure the hall effect sensor between the magnets you want to levitate and the inductor.
- Adding mass to the levitated object will dampen the oscillations induced by the comparator.
Wireless Power Transfer Tips:
- Use a square wave generator to drive the N-Channel FET.
- Find the resonant frequency by sweeping through the frequencies (mine was around 200 kHz).
- Keep the magnetwire turns tight together to maximize efficiency.
