The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
no I didnt get vids. not yet but im almost done with the full bridge and much larger MMC I should be able to put on a show by Monday. All I need to do is mount the heat sinks and build a place to mount everything, connect the cables,and slowly ramp up the power and tune it. Then I am done.
ok so here are some pics of my new H-bridge and larger MMC I will be soon mounting it all and have it running in a couple of days. The huge line filter is 40A 120V or 36A at 240V and I got it for $3.50 I have 6 more caps and I was thinking of putting them all on the mmc but I don't know what do you think?
I got the H-bridge working, now I am packaging it and should have it sparking by Tuesday night. thanks for all the help and I will be posting pics the problem was I had the 2 half bridges running in parrellel not switching.
I got it to work I have only brought it to 50% AC in and I am getting over 30" spray. the Indiana johns theme song was extreamly loud and clear! I will be posting pics tonight when you can see everything better I will also add more Tank capacitance to improve performance.
ok so I haven't had a chance to run it past 20% AC in but I made a video of it playing Indiana johns at 12% AC in inside I will be Posting one of it playing at full power soon.

Oh that is cool!! Sounds absolutely crap, but that's what you get with plasma as a speaker! Well done, Daniel, amazing to see how quick you got it up and going. Look forward to the big sparks.

If you would play with some audio filters you can get some better sound, I use an automatic gain controller to get a verry consistent audio signal so that al the peaks just stick out above logical level.
It's played on my small mosfet drsstc @ 30 volt dc input. Enjoy Ram Jam Black Betty ]1185531655_639_FT27335_low_powerdrsstc.avi[/file]
