I love it, nice work! I always knew it was possible to make a working Tesla coil from nothing but a microwave oven, I just never had the ambition to try it. The primary tank capacitor was the part that deterred me.

Details here including photos: https://plus.google.com/u/0/+PeterTerren/posts/FnGcdK5773d "This Tesla coil is made only from parts from a single microwave oven. It was part of a challenge to the 4HV community to see who could make one first. Here are the tech details. The microwave oven transformer supplies 2000VAC which is voltage doubled with the 140 nF capacitor and diode to around 3,500VDC. The primary winding came from the 6Volt heater winding from the main transformer. The very fine Tesla coil secondary wire came from the fan motor windings and is supported by the triangular wheel platter support. The spark gap was constructed from a stripped circuit board and some aluminium strips. So what about the capacitors here? The tricky part was to open the original 1uF oil filled capacitor and unroll windings then reconnect them to form a a 140nf 3.5kV capacitor for the doubler and the main Tesla tank cap of 1nF at perhaps 10kV. Plus the original cardboard former was taken out washed and used as the secondary former. It worked. The capacitors died fairly quickly but proof of principle was established." Even had some racing sparks._______________________________________________ Tesla mailing list Tesla@xxxxxxxxxxxxxxxxxx https://www.pupman.com/mailman/listinfo/tesla _______________________________________________ Tesla mailing list Tesla@xxxxxxxxxxxxxxxxxx https://www.pupman.com/mailman/listinfo/tesla
