[Dragonfly DIY] ZVS induction heater

I've been looking at these little $40 induction heaters, thinking it would allow me to do most of the small metal bending I need to do (rods, bolts, etc) without having to buy an oxy-acetylene torch.

I finally ordered one and decided to have a quick go this evening. Obviously it needs proper mounting, water cooling, etc but this is just to prove it works.

This was attached to two 12V wheelchair SLA batteries for 24 volts input. It will run from 12 to 48 volts. At 24 volts it's probably only putting out about 350 watts (guessing). The higher the voltage, the more amps it draws.
