I've seen some very interesting videos recently using high voltage for doing wood burning. The techniques rely on using a microwave oven transformer or some called an oil burner transformer to step up the 115 VAC line voltage to several thousand and then use high voltage probes to electrify the wood and cause lightening like wood burns. Does anyone here have experience with this and if so, what equipment have you used? I'm thinking this might be a fun (albeit potentially dangerous) thung to try.
