DC-DC 12V-1kV
@Ross, I'm using SM4937, they are rated to 600V and have 200nS recovery time. The caps are 0.1µF/1kV. Here's a closeup, sorry for the excess of flux :)

DC-DC 12V-1kV
I don't know, this thing is so unstable. The only thing it doesn't react to is me blinking the eyes, everything else is instantly displayed and in the most unpredictable manner....

DC-DC 12V-1kV
Okay, so I have advanced a bit. I have all the high voltages, adjustable and everything in HV is like I expected (full span is -450..+300). However 6.3V is giving me trouble. As...

What's your experience so far, is V-USB fast/reliable enough to handle all those furious button presses in Metal Slug?

Synth ADSR Envelope Generation
Can you use Bresenham's integer line algorithm for ADSR? It's very simple and fast.

Okay that's cool! I wouldn't say that when one of the ends is grounded there's nothing to isolate either. A picture due from the last night Those little square thingies on the...

Mmm one another: I tinkered a lot in the circuitlab and came up with this layout: So far I only tried the top part of it and it appears to work...
