The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
Oh no, sorry this thread should go to the ** Add your Tesla coil here ** topic , can someone fix this? thanks. - obsolete
Modified Steve's mini sstc design scheme: secondary:23x11cm half-bridge: HGTG30N60B3D's or IRFP460's for lower preformace sparks length: about 50cm this coil is interrupted drsstc with half-wave rectifier max streamers lenght is archived on interrupter ON and OFF time limits(almost like a CW) in this mode maximum power in is 2300W I recommand to watch this video ..enjoy
Hi, Thanks With 460's preformace is litlle bit smaller but more safer and stable, power input is max 1400W and streamers are about 45cm long, but 460 get more hotter than igbts on bigger power..:) also i have a video with these 460's on youtube called 'drsstc brutal' ;)

Nice coil!! Very nice! You can only have 2-3 photos for the "Add your Tesla coil" thread, so you might want to do it again rather than having this one moved.

hey mmt,
I really thought you had a different modulator because the "Bangs" wont snycro with the 555 "ticks"... so that is HOW it should sound with a DR.. nice!!
pretty much different from an SSTC w/c the "bangs" are the same with the 555 "ticks"...
btw, Im making my SSTC into a DR, but 1st im rebuilding the driver board.. I have the osc/driver up and running (Im using the minibrute schema).. but Im using a single 555 for the modulator (for now) since its still an SSTC im using a "remote" interruptor and coupled to the interruptor input with opto-coupler...
will post post new pics of it once Im done rebuilding the half-bridge IRFP450 (for SSTC)
DR will happen when I get IRFP460 (lack of money for now)
Those bangs may sounds differrent and irregular because I have there a half-wave rectified bridge, so i get spark only when meets 50Hz from mains and pulses from 555 interruper. I concludes this combination however makes irregular freqence of sparks but decreases the input power and temperature on heatsinks. But mostly how sparks sounds affect on the interrupter and toroid.

That's very nice. I have a few questions, what frequency does it run at, and how do you adjust the primary tuning? Also, I see it uses antenna feedback, that is pretty unusual and interesting.
It runs at 188kHz, i didnt make any special primary tunning, just some bacis calculations for CAP witch currently have 62nF. Yeah it has a antena feedback i tried CT, VCO, PLL, TTL but this antena shows best.
