The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
I worked on a small SGTC and I finished it but the performance isn't that great. here are some pics its driven by a fly back transformer.
Never mind I got a 1/2" sparks to the air from the brake out point I just needed 2 more windings Ill post pics tonight when the lighting is better also what is the best way to take pictures so faint sparks?

Looks cool. What are its dimensions and the size of its tank cap? Depending on the size I bet you could get a lot more out of it. Here's one I made. http://www.youtube.com/watch?v=JEuv6GAEnVE Its secondary is about an inch in dia. by around 8-9 inches tall. (not that great of an aspect ratio) It puts out streamers from a break out point that are around 5-6 inches and with more power sent to the flyback I can get upto about 8. But anyways, do you have any other specs on it?

It probably just needs tuning. Also when the sparks are wimpy and long like that the spark gap is too wide. I found I had to use tight coupling and high BPS to get good streamers from my tiny coil.
ok so I totaly screwed up and now I fixed it the coil will pout out 6" long streamers (as long as the coil) but you can only see 3" on the camera. here are some pics this coil is defently a keeper.

Looks great! Your spark length, at least spark lenght to coil size, is beating my mini coil. ;)
I got some questions for ya too. :)
What driver do you have running the flyback? If it's ZVS what voltage/amperage(if you have a way of metering it) are you putting into the flyback? Also are you running a DC flyback or an AC one? Also what guage wire are you using?
BTW: For taking pictures you can try first making sure that the camera's flash is off, the shutter rate (ISO) is set low, and that your room lighting is also low. Usually camera's have a manual mode that allows you to change these options.
ok so I am using a ZVS PSU and I am running it at 47V at 6A and I have 7 turns on each leg so 14 total. The flyback is a DC flyback but I thought it was an AC one because it didnt have a filter cap so only one I hoocked it up I realized how good this one was. I will build a new deiver with this center taped because I have 4 of them and I can buy 40 of them for $4 each at the stor I go to. the wite I was using was 16AWG and everything was getting hot espeacially the IGBTs but when I added a fan I cooled everything down verry well. Last thing is tha this is verry cool it defently is a huge improvement and I added 3 more turns and the spark length increased even more.
