i used just twisted pair and it worked out fine. but if youd like im sure it cant hurt to use shielding. I just use shielded cable for transferring of my interrupter signal. I got an RCA cable and split open the insulation and connected the shielding in the cable to the mesh shield i have going aronud the base of my coil. Anyways keep up the awesome work!

I built the heat sink. Didn't come out very pretty so i might change it.
However i tested it. I clamped a heater to it and let a 500 W trough it. After 10 minutes the copper piece was cold and aluminum part was warm (without installed fan). With fan this will be a great heat sink, it just does not look pretty, i think

Hello,
i decided to change the heat sink again, because that one was ugly
I searched for hours until i found a shop which has old Sempron heat sinks. Bought two and made it like on photos. I made the primary supports. If all will go successfully i will wind the primary this weekend and wire it up.

So i winded the primary and still have 3 more critical points to do:
Get a MMC caps ( HELP ) Finish the interrupter Order the spun toroid
And let it run at full power...
But until then i had to try it, just little to feed addiction for sparks. I made a MMC from some small crappy caps, made a interrupter on test board and added a sphere as top load.
Here is what i got with 100 VDC in.:
Completly untuned, completly unsuitable MMC, completly bad alligator test wiring. Not bad . I played couple of minutes and everything was ice cold and working fine. Except the over temp light goes on as soon i turn on the coil. I will need to investigate what is happening.
Cant wait to finish it and let the full power in, i cant !
