This video shows how I built a mechanical inverter/transformer, which can take 3V DC from a pair of AA Batteries and turn it into 700V. A long time ago before I knew how to build a solid state inverter circuit, I was curious about building a device like this as an alternative to generate AC from DC. It isn't really practical, but it's a really interesting toy to build/play with.
I use 16 6mm x 4mm neodymium magnets for the rotor with alternating N-S-N-S polarity and 16 coils made from #6 screws wound with about 1,300 turns of 32 gauge magnet wire. The rotor is driven by a 3V motor that turns at about 2,800 RPM.
The multiplier circuit uses 100 nF film capacitors with 1N4006 diodes.
