Tesla coil - SSTC with Arduino

My 2nd tesla coil
Primary 7 turns
Secondary 1035 turns of 32AWG (0.21mm) enamelled wire on 7.5cm (3") diameter
3d printed toroid covered in foil tape.
~Runs at around 385 Khz
4 x IRFP460A (20 amp) mosfets - underpowered but you have to start somewhere...
~60V across the bridge
Based off Loneoceans SSTC2 but using a full bridge, and Arduino as interrupter. Note that the loneoceans schematic has a mistake in the feedback core section. You want to clamp the feedback after the 0.1uF capacitor or it won't work.

The interrupter allows you to put a lot more energy into driving the coil when its on (without overheating the mosfets), giving you much better sparks, as you can run a duty cycle of say ~5%.
