Those little transformers are really bunch of high voltage fun, and people seem to have done many interesting things with them. So I decided to put up a little "contest". Actually not a contest, just a thread where people can show off their projects. No prize or anything, this is just for fun wink

The only rule is the camera transformer(s) must be the only hv supply on the device.

All kinds of projects are welcome, including tesla coils, CWs, marx gens, coilguns... you name it!

Here are my *entries*:

A SGTC using two of these transformers:

Well, here's my toy from way back: Link2

I haven't messed with cameras in a long time now but, hey, you never know. I got a job in a camera shop the other day. (Photographic lab technician.)

My Candybox HV gives a 1 inch spark. It uses a Camera supply driving a 2.2uF cap which gets charged to 250V before a SIDAC dumps the charge into 14 turns around a flyback.
The camera circuit has a mod to keep it turned on and the main transistor was changed to a BD140.
