Photo of my homebrew transformer:
The tank and the transformer:
The cover:
Winding process:
Me at the winding machine..
500 Bifilar Turns of 1,25 mm heavy duty magnet wire for primary 120.000 Turns (60.000 each winding) of 0.15 magnet wire
and finally 40 liter of Shell diala DX !!!
At least the photo of the arcs..
WOW! That is pretty freaking sweet! Do you know the voltage/current output? And is it limited? And watts? :P Homewound transformers always amaze me.
@LithiumLord: That first pic looks awesome! (i think it was the first pic, i saw it yesterday :P) Well, all of them look awesome, but the top is ma favorite.

here are a few pics you might enjoy, especially the bottom ones for those in line for the junk box! in this order: "Frankenstein Does Drugs!" "Imagination-Land Is Surrounded!" "Manufactured Art" (painting rendition, later used in sculpture awaiting photo) "Under the Eastern Stars" "Camera Graffiti" (OMG)"Monkey Tron" (guess the location. hint: it's not the Grand Canyon)
The last two are some pictures of the entire assembly from which my "larger" contribution to the junk box will come (being symmetric, independent board design, the rest of it will function hint) and take a guess what it is! - I posted one of the chips to help you out

I asked you to guess what that pic was, it's for the junk box!
and some pics are really high res and others aren't (change of cameras, but the main thing is that to make the file size proper, I cropped a VERY small sliver around some edges of the pics to make it fit under 2 megs, but I don't know if Vista expanded it to original size...

DaJJHman, it looks like some sort of optical equipment, so I would have guess a laser of some sort? Or perhaps a sweet camera... perhaps a high speed camera?

Blew stuff up with the cap bank. Is was 12.5uf and 2kv(7650 max voltage which is 365joules) which is 25 joules.
First one is all the transistor/mosfets i blew up(they where dead, don't worry). First is all of the semiconductors i blew, the second and third are HOT's(horizontal output transistors, in televisions) the fourth is a 20amp 500volt mosfet, the fifth and sixth are two semiconductors(idk what they are, they are freaking old, out of a tv) on a circuit board. In the fifth pic, the semiconductor on the left, the front is still intact, and the right one had all the black stuff blown off. They are the thinks with the 'tabs' that mount them to the heatsink. The sixth pic is the same semiconductors' back side. The last pic is the HOT in the third pic, next to a scr with the same exact package.

Before Daniel Uhrenholt left to his new job at Aalborg University Robot Lab, this was the last thing he made on the wire edm. machine at his old job: Cooling finns out of solid copper for the opto`s for the CCPS. Blowing up opto`s showed us, that the black spot was on the belly of the chip. So the heatsink is designed to suck heat out between the legs of the chip. They suck like a million dollar wh*re. The opto`s like it. Wouldn`t you?
