Paul & Sabrina's cheap DIY 144v motor controller

[MPaulHolmes]

The current sensor boards arrived yesterday or thursday I think, and I got all the boards and what nots all shipped out yesterday USPS priority. Well, Sabrina did. haha. ya! I got one current sensor board soldered and attached to the first of 4 1000amp controllers. It's basically done, other than an enclosure. I need to test it, but it's been finals week, and I have no time whatsoever! I'll be gone next week, but I'll get those dang things done a lot quicker now that I know how it all fits together. It takes forever when you are making it up as you go and trying different things.

oh boy! this means my boards are gonna be on the way soon i shall have to get my other components ordered right away... lookin forward to soldering them together!

*edit* Got all of the components ordered for the control board and the driver board. only place i was able to find 1000V ultra-fast diodes was on-semiconductors, and they have a minimum order of something like 5000. but i requested a free sample, so i should have about six extras if anyone is needing them. this is for the igbt driver board.

mrbigh: i got my vla chips today. thanks! box was a little rough when it got here, but they should be fine...if they can't handle a little shipping they're gonna cry when they see what i have in mind for them.

also got my igbt's today. 300 amp, 600 volt, single modules. i have four of them, and they're brand new. if anyone wants them, i'd sell them cheap (paid 25 each for them, i'd sell them for less)

horatio (MRBIGH) had some, and i believe he has a couple more. he sold them to me for roughly 45 dollars each. i think this was about what he paid for them.
