Hello

This is my first 'real' project so to speak, and i didnt really want anything else than some easy, fast, electricial discharges in a slightly oversized light bulb, hence i didnt do any calculations on the number of windings, tank capacitor and so forth, i basicly just build it. So in short, its not a very effecient, but it works.

It is basicly a SGTC with a light bulb instead of the usual top load.

Specs:

200turns on secondary (roughly, didnt really count)
16turns primary
15-20kV suplied from a flyback transformer
3.3nF tank capacitor (mmc)
topload is a light bulb

The spark gap is just two steel nuts on bolts, not very effecient at all, but it works, and im happy about the results.

The flyback and its driver circuit is in the metal PSU box, the green box above contains the spark gab and tank capacitor. Rest is pretty obivous i supose, coils and light bubl.

I'll be trying to shoot a video of it but my camera is not very good, all ive got at the moment is this picture: Link2

edit: heres the video i promised yesterday, its very low quality video but i guess its better then nothing.. Link2 confused


best regards gl00d

That turned out very nice! I still havent got by that lampstore and bought a lamp myself, but it looks so nice that i really should :)

You really should check your setup with JAVATC and get it tuned, well worth the time.

Did you shortcircuit the filament and ground of the bulb, read somewhere it should increase plasmaglobe performance.

We should get together and start the Odense Tesla Coil Syndicate :D

Haha Odense Tesla Coil Syndicate , i like the sound of that :D

I just took both of the wires from the lamp socket and soldered them to one of wires from the Secondary, and put the other wire from Secondary into the earth outside my house.
