My coils are mostly described at

My first coil was powered by a 250VA OBIT. With 1.5" diameter 1 foot tall black PVC secondary giving 3" sparks. My second coil, which was never completed :( It had four 9kv 30ma NSTs connected in parrellel which is fed to a sucker gap system. The secondary was about 1.5-2 foot high and 3" in diameter. My latest coils where mini ones that I had built early this year.

Videos of the micro coils can be found on my Youtube account.

As a Tv engineer, i was naturally drawn to the SSTC,
my first coil being a replica of Richie Burnett, about six years ago.
I then made a copy of the driver electronics of a guy named 'Chester'
i went on to make copies of SSTC's from 'Justin And Arrons' site.
But as i then saw the experiments of Steve Ward on the DRSSTC,
i went on to build four DRSSTC's of variable sizes which are still
functioning today, so i guess i'm just a good copier of other peoples coils!.......lol

Heh, well

...
My first coil was powered with 12V by a self oscillating relay pulsing a small mains transformer (10V/230V) which stepped the voltage upwards up to some 6kv. That charged a small leyden jar (made of a film can). Spark gap was two pieces of wire. Secondary coil had propably 100 turns of 0.3 mm wire wound on a 3/4" PVC wire... Believe it or not, it worked!! Although the corona could be seen only in a very dark room. Biggest strike was ~5mm

My latest coil is here, and now I'm working on a coil like Derek's EnyWeenies.

mh, ive been workin on teslacoils since 2003 i think and build several types, from sgtc to vttc over sstc and drsstc. made some experiments about using scrs as sparkgap replacement etc.
so ive build 3 vttcs, one with a pl519 tube which was very small and gave around 5cm streamers, a vttc with a russian gu50 tube which gave around 5-6cm streamers, and my new 13,5mhz bottom feed vttc which blows over 800watts rf power into the air, resultiing in a nearly 8cm high cw plasma flame :P.

i started with a small obit powered sgtc, but the results were not promising so i scrapped the idea soon and was dissapointed. after i got several nsts i gave it a try and build my sgtc3 which worked very well. 7,5kv 50mA transformer. i brought this sgtc to my old school for several demos etc in 2005.

between my sgtc work i had time to go deeper and started to build my first sstc, which was very small and worked bad, but this was my start into electronic teslacoils in all variations. soon after that i build my mini sstc2 which is very popular here in my forum in germany, cause it is simple to build and much forgiving

after that i started to build much more complicated things like drsstcs whit overcurrent detection and modulators with realtime 7segment displays, without using microcontrollers etc.
i build 7 drsstcs until now. many of them worked really great.
more infos and pics on my website or on my forum, for those who can understand a bit of german its not too complicated to get on the right place ..

Haha... Tesla Coils... I made one a few years back that basically consisted of a flyback outputting 15kV charging a single 1.2kV .047uF capacitor that discharged via a spark gap to a primary made of 22 gauge wire and a secondary that was an 8" PVC pipe wound with deflection coil wire. I got 1" streamers out of it before the capacitor obviously died. I'd like to try this setup again with a larger bank of 12 630V .1uF capacitors and a taller secondary.

I've set up a photo gallery on my server. Here's the link to the Tesla coil page:

It's not all the coils I've built, just the ones that lasted long enough to take a picture of before they exploded/caught on fire/or was disassembled to make a different one.

i used to work with coil guns than i found the coilgun on tesladownunder.com and after looking at his site i have been in love with tesla coils ever sence
