I actually think this one is better for a first SSTC beacause it doesn't need mains power and the parts are simpler. As far as tried and tested, Steves mini is the way to go. I'll let you know how it works once I've built it, if someone doesn't build it first.

I have built the board and am wateing for FETs. It is a lot of work to go through for a measly 5" inches worth of spark so I am going to dubble up on the FETs IRFB3077PBF and input voltage in an efort to increase spark length. NB

I had a look at those FETs teravolt, and they look good, cheaper than the suggested ones too. I will also go with those ones, when I have time to build it. Kids suck time like you wouldn't believe!

Just wondering, Does anyone or can any tell\guess what those batteries that he is using are rated for current wise? I pulled up the palma battery website but the have about 50 batteries on their 12v line and they range anywhere from .7ah to 230ah.

Thanks for the input Uzzors. Looking over some of this plus Mikes post with the parts, I noticed while watching the vid on WMP L1 and L2 is just a single layer of IDe cable and every other wire is connected in parallel, I guess to increase coupling or something.

Well folks I managed to build the skori, And its pretty interesting (no photos yet). Suliman the zener, fet, and Bjt makes an interesting voltage regulator, if you run the coil at 12v it gives the 555 part of the circuit a 8.56v supply and it stays at about 3.5v difference, untill about 15v input then the circuit taps out at 11.25v even when the input hits the 30v which was the max voltage my borrowed power supply could put out. As for who ever if anyone, wanted to know how he got good arcs for 12-24v its cuz its using the massive current capable puma battery's, the power supply I was using could only pump out about 2A at 24v, and I could only get maybe 1-2 thin arcs drawn to a nail I had in my hand and it was over currenting the supply, it was even weak enough, I could draw the arc to my fingers and it just felt like a fly was walking on my finger, although...My resonant L4,C4 circuit was based on a calculated value. All in all even with the current limitations I noticed that the circuit at 24V 2A could produce a visible corona around the primary.

Woops, the fets were 110A 55V. Which of the circuits did you use, WhiteArc? ATX PSUs can supply from 12 - 30A on the 12V line, don't have any lying around?

Nope, the ONLY working Atx aside from the ones in working pcs is the the 12v source for my larger coils 12v and 5v electronics. I used Mini coil 2 Also I did take 2 vids of the low current arcs.
