You've always been an awesome beta tester.

I finally got around to reading the datasheet for the 6 igbts I have.

By the way, I only have 6, and my plan is to use 3 per controller. So, if I do 3 prototypes, I'm no mathematician, but that's 9. Here are some cheap ones that are from Tesseract, and I know for a fact are new and not bootleg from China:

I was thinking for prototypes, Duncan, jedsmd, and flores, do you guys want to split the cost of those 4 ways with me? I can't mix the igbts I have with the ones above, as they are different parts, and it would be asking for trouble. It would be around $99 each person (including shipping). Alternatively, we would need to figure out which 2 of the 3 beta testers get the free ones I already have, and which poor sucker gets to buy his own. hahaha. Note: Guy with golf cart, this controller will vaporize the golf cart motor. I don't think it's a good idea. I'm hoping for a peak of maybe 1500-1800 amps. If it actually works, you guys need to promise to take a video of a burnout, even if it has to be on ice or gravel. Ideally, dry cement, but wet pavement would also be acceptable.
