Lots of new stuff coming on the wiki! ya! Also, don't pay for overnighting anything when the next day is Saturday. It's really really expensive.

Hopefully I will finish my (very crude and feature-free) controller in a few weeks. Anybody got the equipment to test it up to 1200 amps? I don't have a motor or battery pack for testing. (P.S. - Disclaimer: Not responsible for accidents).

This looks interesting - look at 4:

"Case 2 shows the remote control of the air-conditioning in the car. Because charged power is very precious, user can cool down the room before leaving the car during summer season. Case3 is the example of data synchronization between entertainment devices such as TV, DVR both the home and Electric Vehicle. Case 4 shows the convenient application for self-diagnostics of the car. When the EV detect problems in the car it sends the maintenance data to the service station of the car dealer through the internet. Case 5 is the feature of messaging service when the charging has been completed."

I might have to spend $50 and stick a powerline ethernet adapter on the charger then connect it to the car somehow. The controller and charger would be the first things to get connected for me, climate control and music sync would have to come later.

I would be happy to put your controller in my car and do burn-outs in fifth gear!
I'll just need to order a kilo-amp fuse and it will work great!

I've been looking for the same fuse myself. Can't seem to find them at Wal-mart.

Princeton, Ben will kill your controller and then dance on the ashes, I'm warning you.

Well, I think I need a new oscilloscope, or new oscilloscope leads. It just shows a dot on the screen when I try to see of the fully assembled AC controller's 6 pwms are working like they should. Makes me mad. Now, technically, it's my fault because I plugged the leads in the wrong holes in the power outlet over the summer at the school. It took them 2 months to reset the fuse in the class. hahaha. We had to go without a clock or pretty much anything for the whole summer, and it melted the ground lead on the oscilloscope probe. So maybe that's why it's not working. haha.

Just a shot in the dark but have you got the timebase set to x-y mode?

[MPaulHolmes]

That could be. But every other setting just had a blank screen. It's a piece of junk. $129 new. haha.

If Ben decides to pass up the opportunity I have a car with a 9 inch motor and 132 volts in it that has a dead curtis 1231c in it. I promise that when I kill it I won't dance on the ashes .
