Just some test results .... for tube lit with one wire.

EDIT: It also works with 1.5 volt battery, but tube is not lit as bright.

Xee2:

Am I correct in thinking that you are using a virtual ground as Dr. Stiffler and Lidmotor, Jonnydavro, etc. are doing?  That is very cool.

Just for kicks I ran my Pirate tube light on 3 volts going into the Fuji and, the Fuji circuit handled it just fine and the tube (18") was really much brighter.  I may have to play around some more with 3 volts input.

I did stick a strong neo on the side of the transformer which made it even brighter and there was no squeal that I could hear. It must have raised the frequency as it did on the Jeanna Light.

I am not sure what they are doing. My circuit is closed by capacitive coupling between tube and can.

The can was inspired by jonnydavro pans.

N0. I only have one. But I think that might work.
