I was thinking of calling it "The Stinky Diaper", because it's inappropriate and unprofessional, and I change a lot of diapers. If that sounds like a bad idea, I'm open to suggestions. haha. I'm horrible at coming up with names.

There is one capacitor that needs to be added to the board (grr), but it's easy enough to include it by soldering it to 2 caps that are already on the board. Boy that was annoying. Also, I would probably dump 2 of the 3 current sensors and just depend on the DESAT detection on those instead of the extra hardware overcurrent protection. I don't know though. Redundancy is good, but it also adds cost.

I still have like 5 or 6 boards which are just biodegrading in my shop. haha. It has a single surface mount part which is a SOIC16 wide. It's not too bad to solder. The ring capacitor is now only $150 directly from SBE in quantity 1. But the 3 IGBTs aren't cheap anymore. There are some Littelfuse igbts that are rated for 400amp and are fairly cheap from Mouser ($150 each). The 600amp powerex modules are $257 each. dang it.
