    This must be the must frustrating project ever!

    So far i tried:
    2 secondary coils, a 812 turn in 30g wire and 25.4 cm long in a 3.3 cm of diameter pvc pipe, and the one in the picture is 316 turns in a 2.1 cm diameter pvc pipe and 10.9 cm long.

    3 primary coils, a spiral calculated in javatc and two cilindricals changing orientation for the turns, 4 and 6 turns, and NADA (nothing).
    I have the TIC31C transistor and there you have a schematics for my circuit, but i have read all i can just to replicate successful circuits and NADA, 47 Kohm resistor, LED, when i pull the transistor out the LED turns on, transistor never hot, like chilling, not working.
    I used to work on a protoboard clamping all with those color jaws with wire and NADA, so i placed the circuit in a Perforated coper plate and 2X9 Volt in parallel batteries B3A0E7C1-7452-4329-A2BF-5A63AC41E207.jpeg
    So i need help im going krazy.
    Thanks for your time.

    Ok, update, the led turned on! I placed a ceramic capacitor B3A7F2F7-1DC3-4846-AC18-18D02E65CA34.jpeg , a 392Z 2kv, i believe is a 3.9nF, parallel to the batteries and the spark is very tiny, i can see it just with lights off ifbabscrew driver is touching the wire or aluminium wrapped ping pong ball, and no fluoroscent light is excited to glow (if im do in it right choosing the right light).
    Also i tried with switching the primary coils and the one on the picture works if positive is connected to the wide part of the coil in a clockwise config, or a cilindrical coil in same direction, i tried a different power source, a 5v wall d-link hub transformer and the spark was even smaller, maybe is the capacitance, help!

    Hey it works!
    Ok so new batteries and just touched the bulb with the aluminum ball and suddenly in glowed, all in video, i almost sh** myself...
    So now i must keep improving the tuning and so on, maybe a plasma thing there.

    Get away from the 9V batteries, they aren't made for something like this. If you have to or need to use batteries use multiples of A, AA, C or D cells to get the voltage you want.

    Hi, thanks for the interest, and for quick reply i was thinking of using lithium batteries like the ones i got for the drone projects some years ago from hobby king, because maybe i can improve by a better power source, anyway, i have Enduro mtb and going away for the weekend and notice you next week ok!
