Wireless power with a slayer/exciter circuit

I spent a good couple of hours wrapping the secondary winding for this transformer with 30 AWG magnet wire, and used a slayer/exciter circuit to get kV level voltages. This lets me make small arcs, as well as light up LEDs and flourescent bulbs if brought close.

The next step is to beef up the circuit using high-power MOSFETs to get larger arcs, and the solid state design (as opposed to the old-school spark gap method) will allow me to superimpose audio from a headphone jack on the arcs.

Here's some info on the slayer/exciter circuit, explained my Mehdi.

Combined my love of running and electrons

Used a conventional 20x4 LCD and a Real-Time Clock module connected to an Arduino microcontroller to calculate how much time I have to train for my first marathon.
