I'm hoping that tonight I will find out what the surprise is that MPaulHomes' wife and brother bought for him. The suspense is killing me.

And thanks ever so much for the "naked picture ahead" warning. I shall shield mine virgin eyes.

Paul is correct. It is done by rotating the entire assembly that holds the brushes.. on some motors you have to drill new holes to do this, some not.

I have 45 Thundersky LFP160AHA which will do a whopping 3200A for 5 seconds !!

Ok, so I have WAY more than 400 pages to go. That's ok though because this project fascinates me.

"copylefted" (from the quote above) is a broken link (I can't post links yet). It kills me that I'm missing out on seeing Ian's cool stuff. His site seems to be gone. Does anyone know his full name or the name of his project? Maybe I can track him down. (Not in a creepy internet stalker way).

I was sad to see that the secret gift was a plexiglass milling thing that was too flimsy. It's the thought that counts.

You guys are inspiring me. I may have to go find a junker and do an ev conversion.

My wife and I are currently looking for some property (10ish farming community acres) to put a house on. I want to sink a well and have solar power. Go "off the grid". Maybe I'll end up doing an open source solar power project.

When the zombie apocalypse comes you guys will be welcome at my place.

Check here, I think he reorganized things:
Zero Emission Vehicles Australia

LOL I forgot about the flimsy milling thing. That went straight to the garbage, after expressing great gratitude.

The boards just shipped. There are 10 of them. It was something like $350 + $175 ($175 for my screw up) lol including shipping, so if anyone wants one for $35.10, they can have one (slight profit margin). Man, I couldn't bring myself to figure out what $350 + $175 was. haha. It is both the control board and 3 drivers in one board. 4 layers. um.. and other stuff probably. I can solder the one surface mount component for anyone that needs help. I don't have any of the FOD8316, so you'd have to buy it though. I need to order me some of them, for real!

DHL Tracking number: 1077685674.

One interesting thing: If there is a voltage on the bus capacitor, the driver/desaturation detection chip (FOD8316) has a desaturation fault on startup. It doesn't mean that there was an actual desaturation event though. I used to think that was really a dumb flaw, but it's just being safe. There's no way that uncontrolled voltage can go through IGBTs that may or may not be opened, before the microcontroller has a chance to start doing its thing. It starts up in a disabled, fault state. Nice Job, FOD8316 people! That's using your noodle.
