Hey all,
We (oneTesla <http://onetesla.com/about>) have just launched a Kickstarter
campaign
<https://www.kickstarter.com/projects/onetesla/tinytesla-the-little-singing-tesla-coil-anyone-can>
for a pair of coil kits that might interest you - tinyTesla, a small MIDI
SSTC, and oneTeslaTS, a desktop DRSSTC.
There's a lot of info on the Kickstarter page, but here's a summary of the
cool features the coils have:
- Both kits are MIDI controlled; oneTeslaTS is controlled via the
traditional computer->MIDI Adapter->Interrupter pathway, while tinyTesla's
interrupter connects via USB and shows up as a USB-MIDI adapter. Both
interrupters are fiber-optically isolated.
- Zero tuning required. In particular, TS's secondaries are all
identical down to the last turn, and the primaries are spirals on a 4oz
PCB, so each and every coil should perform identically.
- Both coils are super-compact, mostly thanks to the fact that our
coil-winding partner can wind very high fill factor secondaries TS has a
6.5" secondary and 6"x1.5" topload that resonates at 250KHz, and tiny has a
3.5"x3" secondary that runs at around 450KHz unloaded.
- We tried hard to keep the primary current down on TS; it sits at
around 200A right now, which is not too hard on the 180A-rated IGBT's. This
should give a longer lasting coil.
Thanks in advance for your support, and feel free to ask questions!
