high voltage current source (mirror)

[coppercone2]

if anyone knows of a higher voltage BJT... I will probobly try it.

But I did also get a shit load of 2sc's for experimenting with 'ladder mirrors' . I am happy that they appear at least somewhat hard to really 'break' in a classical sense

shame though, with the age of this part, I figured we would be at 30kV "enhanced package to-220" transistors with teflon pants

and I would be happy to try any 2SC ladder type circuits that anyone wants to come up with, I might even have a crappy 5kV power source from some air purifier, maybe

The AOE has something, I think its derived from this



I spent some time looking at AOE circuit, and I am not sure if you need to do that with BJT. It looks like you would actually need to test the configurations to look for the bumps they describe.

this might be a reason to buy a decade or two of E values of some high voltage resistors for experimenting on.


And my idea for securing the transistor is now to solder a solid wire to the top of the can and solder it to the negative banana terminal on the chassis, it should stop it dangling like it is in the picture, or just secure it to a nylon bolt if it is better ungrounded.


This might be a good technique for complex dead bug circuits, to solder a thicker wire to the top of a can and secure it to a insulating post. Though I guess it acts like a bit of an antenna.

Lol, or to solder a loop to the top of it, and 'bolt' it to a long, possibly heat-bended nylon or other bolt LOL. All the slow mechanical BS is getting on my nerves. There has to be a way other then trying to make god damn circuit boards for everything. Though, as far as easy to engineer, soldering loops to the top of transistors and bending plastic bolts into shape might not be such a terrible choice.

I am gonna get some extra long 8-32 nylon threaded rod to find out if it can work! I don't see many easy techniques for high voltage durable prototyping. If you have a laser cutter I guess you can make acrylic cuttings, but this might just work.
