Paul & Sabrina's cheap DIY 144v motor controller

[flores]

Yeah!!! Mail..

Oh wait.. it's real small for a controller.. oh.. only tape and a wire..

Good news is that the controller can't be far behind..

[MPaulHolmes]

Weird. The tape was supposed to be the slow shipping way.

[flores]

Oh oh..

[MPaulHolmes]

I think it was supposed to be slower than 10 business days. I think it's been maybe 6 or 7 business days. It was greased lightning!

[flores]

btw.. where is the tape supposed to go?

[MPaulHolmes]

Oh ya, minor details. I took a picture. Let me find it.

You'll have to remove the capacitor and add the tape like this:


The holes are about 5/8 inch diameter. Without the kapton tape (that tape can withstand around 15000 volts), the metal things on the capacitor will almost be touching the B+ copper sheet. I forgot to include that when I put yours "sort of together".

You also have to drill the 4 holes to connect the capacitor to the enclosure, and also the 4 holes for the dc-dc that gets mounted to the inside top of the controller. What can I say, I was in a rush to mail it! haha.

Haha.. I see.. no problem..

So I guess it hasn't been tested ..

[flores]

I hope it will be here for the weekend...

Probably customs are calculating how much they gonna screw me for right now..

[MPaulHolmes]

I'm fairly certain the control board has been tested a couple months ago. Well, I do know I tested Duncan's, and yours is identical. And since my soldering skills are crazy mad good, the probability is within epsilon of zero that it will not work, where epsilon is very small indeed. lol

I think the value was $45. I can't remember, but that feels familiar. I feel that the probability that I wrote $45 is close to 1. Definitely within 1 unit of zero. So, the probability is between 0 and 1. haha.

Oh.. by the way.. that 1000A current sensor I bought on ebay.. it measures till 1999A amps..

If it wasn't a DOA.. but I fixed that with some mad good soldering skills also.. crappy chinese electronics.

Anyway.. gonna mount it in the dash.. so I can tell when burnouts should occur..

You maxed it at 2000A right? or 1200?
