Light dimmer: 1000w. 2 bucks (dollar)
Neon sign transformer: input 220 vac, 50-60 Hz. Output 8000 vac, 10 mA, 31 kHz. 5bucks.
L2=464.72cm (These are calculation from D2), D2=9.25cm (3" PVC), N2=16 turns
=> L1=1/4 L2=116.2cm, D1=6.75cm (2" PVC), N1=5.48 turns
Depend on how big wire diameter. Dia. of pipe plus dia. of wire.
L1 cap.
Qty. 5 (all the same), value: 0.066 MD, 1600 vdc
I would say the reason those caps set up that way, because positive go to negative. The 3 parallel caps absorb return better. You can feel faster sparks for setup this way.
L2 caps.
Qty. 3 (all the same), value: 0.022 MD, 1600 vdc
If you use double coil on L2, then I recommend you will have caps for additional coil for better resonance. You should use ac caps for this L2 coils.
Does it work as Don said in the video ?
I would say it is agreeable, and decision is all yours.
Can you make it forever working setup like never discharge battery powered device?
Possible and Frankly, I only have the system working up to here, which is power output from L2. Due to the lack of HV diodes and equipments I can not go on, but I see a very good helping info from Peterae. However, I hope to see more results from all up here, because I see some of you have very excellence equipments and setups, which are voltmeter, frequency meter, oscilloscope, hv diodes, caps, etc. Make me drooling. My measure equip, voltmeter with limit option from china costs about 2 usd.
Spark gap, I would say you adjust your gap farther until you get resonance. I say it is about 2-3 mm or more. Use larger spark contact to ease power transfer.
