Instead of building twelve SSTC's how about these pre built ones? All you need extra is the primary andsecondary coils and power supply. I doubt if you could build a small SSTC for less than the price of these.https://www.ebay.co.uk/itm/12v-SSTC-integrated-drive-board-finished-solid-state-Tesla-coil-of-the-first-TC/183419500594?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
It's hard to know what that unit is, exactly.. is it a 12V in device? or is that the power to the drive electronics, and the actual coil runs off line voltage (or higher). Seems like it would be low power if 12V.
And then there's stuff like this: https://www.ebay.co.uk/itm/miniSSTC-Integrated-Driver-Board-Integrated-Tesla-Coil-SSTC-Driver-Board/273234291283which at least (from the pictures) looks like it will drive something higher than 12V. Not much other info, but I suspect a google for miniSSTC will turn up the original design. (Dan from Eastern Voltage Research?)
and there's bunches of these kind of things: https://www.ebay.co.uk/itm/1800W-ZVS-Induction-Heating-Board-Module-Flyback-Driver-Heater-Tesla-Coil-Fan/253812671224 but again, not a huge amount of information.

I haven't built my first TC yet, but am on the verge. I was wondering if there might be a reliable design I can sort of mass produce for an art project I'm working on. I've been making various artinstallation contributions to Burning Man for a dozen years now, and I havethe prototype for what I call the Kosmik Kalliope (Kosmik Dust is my Burning Man theme camp, so please pardon the awful spelling abuse). The Kalliope currently is a flame effect piece; please see the prototype 13 second video here: https://www.youtube.com/watch?v=-8sDM2_J9J8&feature=youtu.beI have a custom microprocessor that receives MIDI and switches the solenoidvalves accordingly, 12 pipes for the 12 notes of the chromatic scale (it rolls over and plays regardless of the octave a la MOD 12 calc.). I've fashioned a custom igniter so I don't need pilot lights.I am licensed by the Nevada State Fire Marshal to operate flame effects aswell as a pyrotechnics license and I do commercial stuff but my true love is to take art to Burning Man. (o:I've been gathering parts for awhile now (NSTs, MMC and Terry Filter parts,etc.) and I know it is highly recommended to build a SGTC before tackling the solid state stuff, but I've also finished building several of Eric Goodchild's UD2.5 boards I've had laying around for awhile because sometimes I don't work linearly (o: My question: (Sorry for long windedness); I would like to build 12relatively small Tesla Coils (or 24), and was thinking they might be static spark gap units that could be displayed either above or alongside my KosmikKalliope pipes and switch them on and off reliably, like I do the flameeffects? Not looking for massive streamers (6-12"?), but I would like themnoticed by the audience.Is there an available design out there that might meet my intentions, or is this just a crazy idea, whereby the things will strike my stuff and blow up all my other electronics?? (o: They would of course be on stands far awayfrom audiences.I would like to switch them quickly but I'm not interested at this time inactually doing the MIDI modulation; just turn them on and off, as there's lots of other music playing already.I have ten Allanson NSTs (12K 30mA) that are unfortunately GFI and potted,but perhaps could use them the way a previous TCML contributor used them with that resistor network he described? I also have three other NSTs (nonGFI) larger and smaller. Or perhaps MOT TCs would be the way to go? Or a simpler solid state design whereby I could power them all off one large power supply? I have a modest machine shop with lathe, 2 hp CNC mill and 3D printer so I'm not afraid of fabricating. I've toyed with the thought of designing, but as a first-timer, I seem to get stumped with a chicken or the egg thing as far as where do I start? Thanks for all your ideas!
