Self contained flyback

A 1 hour build. Finally put a flyback transformer and driver on a single PCB for easier moving
around. Up to now the transformer has been loose, not attached to a driver PCB.

Note, this is another supply, in addition to my portable supply.

Input: 5 to 15 volts.
Output: 25,000 volts (depending on input).

Bracket with banana socket serves as ground, screw terminals for supply voltage. Arcs are easily 2-3cm, as visible in the photo. Driver is standard 555 + MOSFET. Flyback has primary I wound myself (red wire in the photo).
