Introduction: Homemade High Voltage Pulse Transformer Video

I made this by winding lots of 40AWG wire around a 15mm PVC pipe and then covering it in electrical tape. I then used some 2.5mm2 house wiring as a primary coil and pulsed 1.2kV DC using one of those hand-held bug zappers through a spark gap and a timing capacitor of 0.047uF and the result is a high voltage spark on the output.
