oneTesla

2/3 of power, freq/pulsewidth is 1/2 of knobs turns--not sure what this does, untuned so far, I measured primary res freq of 250.5kHZ and secondary 293.2hHz (may not be 100% accurate) using the function generator method described in stegu's pdf, toroid to ground is about 255ohms.

sweet home alabama:


At first I couldn't get my coil running, everything measured good and passed troubleshooting steps. Turned out to be IEC not plugged all the way in! Took me 2.5 hours to figure it out.

This thing is very loud, my ears were ringing after being done with the runs. Overall this coil performs awesome out of the box, this is my first time building such a device or hearing it in person, it is hell of a experience, thanks to oneTesla for this great kit.

looks pretty good!... i watched the video without sound (i am at work) but is it also storming outside??? what are the other flashes i keep seeing??

Yes it was raining outside .

Don't you think it could have reduced the performance?
Static charges are spreading less in a humid air.

Oddly, in playing with a large (750KV) Van de Graaf generator, I've found that humid air actually leads to longer sparks for some reason, as does running the generator with a large wooden bookcase a few feet away. Static electricity is weird stuff (not that the Tesla secondary discharge has anything to do with static electricity.)
