Paul & Sabrina's cheap DIY 144v motor controller

[MPaulHolmes]

They do need a special driver, but I did my own homemade driver that has desaturation detection, and everything, but is way cheaper than the vla500-01, and is homemade, and is cheaper, and also, it's homemade! haha. It's based around this:

FOD8316 Fairchild Semiconductor | Mouser

What's that you say? That part can only do 2.5amp of drive current? Ya, took care of that, and preserved the desat soft turnoff as well. Pure instinct. The number I was thinking of is (-1 - sqrt(2))^(-3). As no one guessed that, if Duncan doesn't mind joining in the splitting, we'll do that 4 ways. I only need 3 more igbts (for a total of 9), but I'll get 6 out of that deal, so I figured I should help too. Plus, it makes me feel better if something blows up, that some of the money that was set on fire was my own.

There is only one hour left on the auction!

Oh crap! Whoever wants to order them, we can arrange to pay that person back. I'm broke until tomorrow. haha. Flores, if you want to order them and ship to my house, that sounds good.

Poor duncan is on the other side of the earth sleeping right now, not knowing that we are planning his financial future. LOL

Hi Paul
I'm in - tell me how much to pay and when

I'm also with Flores on this
I'm in.. but why are we splitting by four and not three? You don't get anything

Anyway - whatever - tell me how much and how to pay and we will work from there

On that we have a system here (NZ) -
I can use the internet to pay into any bank account - its dead simple and everybody does it -
do you guys have that in the USA?

[flores]

Ha.. I was too late.. but all is fine I see.

So I pay 133$ to Jerald for the IGBT's
And how much do we pay Paul then?

And is Paul gonna assemble everthing or are we gonna do that ourselves?

Shouldn't we include some shipping costs? My stuff has to go to europe..

[flores]

Oh thought of something.. i'm in San Francisco in two weeks.. maybe I can pick some stuff up?
