its a pancake coil with only 86 turns of phone wire 9,000 volt neon sign transformer primary 2 turns arc length about 2 inches the low performance problem is the due to the leyden jar im using im sure witha descent capacitor the spark length would dramatically increase the secondary coil was wound on top of a planters thing i used tack glue to hold the coil down while winding it or else it would have been impossible to wind it like that i would have had to use paper interleaves and i used elmers white glue to insulate it which works great

  • ill probally sell sell this coil with proper capacitance it gives out a nice 4 to 6 inch sparks

  • please make a how-to (if u havent already)

  • ok will do

  • at 1:00 ish you got the camera a little too close...

    if you'd have got it any closer you'd have killed the camera...

    other than that, nice work...

  • thanks but i only used the zoom

  • this was done at very low power levels witha leyden jar at 0.0005 mfd not nearly enough capacitance power source is an ignition coil driven by a light dimmer

  • testing my ability to reply to videos....this is only a test. If this was a real comment, information would follow an introductory sentence. I repeat this is only a test.

  • i use a neon sign transformer or some ignition coils to get the high voltage

  • AC?, how do you get the high voltage?
