DC-DC 12V-1kV
@Nard: I don't notice any problems with my core, I think it's fine for this purpose. 150VAC is low voltage :) Anyway, an update: 0) yesterday i measured ~300Vp-p with a lot of...

Good point about the cathode voltage, I didn't think about this.

DC-DC 12V-1kV
Yeah, I was looking at the same figure, Nard and it was worrying me. So I'm going to get some that have "Maximum Reverse Recovery Time: 200nS". I hope those will perform well. Oh...

DC-DC 12V-1kV
As I'm moving on to the next step and trying to make the current design repeatable. Any hints on reducing the transients without dramatic redesign efforts? For the reference,...

Update: bifilar-rewound the primary. Running at 80kHz now, both transistors are lukewarm. Awesome! Thanks ossi for the bifilar idea.

The symmetry indeed appears to be an issue. I now have a pair of good old IRF630Ns pushpulling my rather nasty looking coil. Here it is so you could have a laugh: The primary is...

I'm carrying on with the project slowly. So here's the pushpull transformer driver: https://www.circuitlab.com/circu... Yesterday I tried it in real life. It worked nicely, up to...

Searching for USB solution
I think FAT could be faked for such application.

Searching for USB solution
I know that there is a V-USB based mass storage implementation, although it's not mentioned on their official page. But don't expect it to be fast. You're probably looking for...

Calibration of internal oscillator
V-USB code has a very nice calibration routine. It uses USB clock as reference signal, of course.

make a bffer with variable buffersize
Actually, in C99 you are allowed to declare arrays of variable lengths. void foo(int n) { char boo[n]; } Is valid code, unless you're living in the ages of K&R C. It...
