Paul & Sabrina's cheap DIY 144v motor controller

[jackbauer]

Thanks adam. Does the iphone not run osx?

edit: got something:

[Tweety]

Eh... Nope... It runs an entirely own OS... With it's own set of rules from Apple on what they allow you to do and not...

As said, they really don't want you to use the bluetooth or serial communication or any of the other fun stuff... So that's not in the Apple dev-kit...

Doesn't mean you can't get to it though... Just means you need the iPhone to be jailbroken to run the code...

I've been through all this with the mpguino, when apple starts paying me to deal with their crap I will consider it

[jackbauer]

ah ok my bad Don't have a problem with the jailbreak! I was never big on buying a product then being told what i can or can't do with it! Anyway back on message I built up another control board using bits i had myself and could source locally and seems to be ok with initial tests. Sadly the only part i could not source was the common mode input choke so i've linked it out for now. For anyone interested here is a list of stock numbers for some of the parts i used from Radionics (Welcome to Radionics On-line)

A probably stupid question but, why there is a vacancy in that 8 pin IC?
Is this Paul's second controller PCB version?

[jackbauer]

I think its the 2c version. I'm just waiting on the mosfet driver they were out of stock

Hello Adamj12b

I went to Wiki to copy and paste the version of software into AVRStudio, so when I compile I get a error complaining that the autocrc.h is missing.
I can not find it any where, am I doing something wrong here.

Cheers

Jeff

Paul,
Though my wife gave me some strange looks when I opened the box and syringes popped out, the parts were so beautiful and shiny that she asked me if I was going to put them under my pillow tonight.....and I just might
And, I got enough packing material to last me a decade!! AND, it was super, super fast!! YOU ROCK!!!!

[MPaulHolmes]

Sabrina packed it! She's really really thorough. hehe.

Hey! they have the mosfet driver in stock! Don't pin that one on me, man! hahaha.

A couple of days ago was our first big snow storm of the year.
It was only about 5 inches, but real heavy, wet stuff, which of course, all turned to ice.

It's also the first time I have driven my car in snow with the Re-Volt controller instead of the Curtis.

Most of the roads are pretty good, but there are still a few icy spots, including in my driveway, in town, and the middle of a few intersections.

I noticed the first time that my front tires lost traction with the road, that they spin up differently than they did with the Curtis.

Because of the "throttle-ramp-up" feature of the controller to limit amps on acceleration, the tires kinda spin funny. It's really hard to describe. I almost didn't realize what was happening at first.

Also, without a tachometer, or engine noise, it's pretty hard to notice that your motor just spun up really fast. Since the tires are just slipping, there's not much load to be reported by the ammeter either!.

Anyways, just wanted to let anyone else running around in the snow with the homebuilt controller to just to know about it.

I will try to give a better report next time I am out driving in the great white slippery-ness!
