Test run of rotary spark gap to make sure that the motor body doesn't liven up and to get the electrode gaps right. Turns out that this was a bad idea, because when i ran it unfiltered, the back E.M.F. in the primary caused the retic system to completely reset in my parents house. good thing i didn't do it at my place :-) P.S. Sorry dad...
I just finished my lively synchronous rotary spark gap, and it's now running with 8kV 50mA NST. It'll service in my 3kVA tesla coil, but then powered with six MOT stack. Motor itself is from old washing machine pump, 1-phase induction motor. It's converted to synchoronous (salient pole-)operation ...
it was my crappiest video yet.but im camera shy!:P.srry you couldnt hear me when i was scooting the camera.was i said about the rotary spark gap was its kinda a peice of crap.there is alot of stored energy in this capacitor.judging by what i have seen from a 14 nf capacitor this one must be around ...
Medium size 15Kv/60mA coil. This is the first test run, with rotary spark gap.
This is my mini tesla coil that is driven by a really small rotary spark gap. Here a 555 drives a 2n3055 that drives an ignition coil that charges a homemade cap made of aluminium foil inside and outside of a pvc pipe that the rotary spark gap discharges to the tesla coil's primary that couples to ...
