Loving your battery install btw. Looks great there. Shame it couldn't flush mount. I think that's a good solution to most DIY EVers too. Don't plan for the perfect. Spend a little money, do it sooner. Get it to drive 30 miles at a time off a small pack that's fairly discretely installed. Spend extra...

I mean, how often are you going to get the chance to race TWO DIY EVs from the same year?

New motorsports league.

Not my first rodeo, I have "built" or ruined a half a dozen of cars in my life so this comes easy, In as much as strangers can observe and judge each other, I'd say you're not good at anything (I dunno, maybe you're an okay father), but you're pretty good at almost everything. And you're ...

For $500, that's a fantastic deal for someone who wants an EV. Just add batteries and go. Heck of a steal.

See? Here you were doubting me that you could convert at 1984 Rabbit in a weekend if you throw some money at it.

64 pulses per revolution. Change numimp to 64 I'm not sure that's actually what that's saying, it just quotes one possible encoder as having 64. But, that's a better guess than I have for any other number. If I disassemble the motor am I going to find an encoder with a number on it that I could loo...

You may require slightly different gains thanks to less than identical component layout? (Just guessing) I’d verify with a current clamp. Don't have a DC clamp meter. Might have a big DC shut and meter around somewhere. Accuracy of the current doesn't bug me unless it uses that to know how to turn ...

You sure about that? This is why SuperFastMatt says never to write down the actual list of stuff to do. Because as soon as you start writing it down you realize how much work it actually is. I'm cheating when I say stuff you could've bought. I kinda include all the design work you maybe technically...

could I convert it to electric in 100 days or less? I hate you. I'm on week #2 of trying to replace u-joints. Not even a part, it's a part of a part. Also, I mean, you can convert a vehicle in a weekend if you felt like it. 90% of what you've done has been stuff that could've been paid for instead ...

Some solutions, some new problems. - I got my encoder hooked up! - I got my temperature sensor hooked up! - I told it to graph IL1 and IL2 when spinning a few hz. Ta da: image.png What's odd is that one of them when "off" isn't at zero... ... Bigger problem, having the encoder plugged in s...

Ahh yes, the holy trinity of angel grinders.

... why would you use MG1?

It's weaker than MG2.

It's in the same housing as MG2.

It's in the same inverter case as MG2.

... You, did not.

And no worries. Just copy/paste the code into the page I linked above. It'll be done.

For safety of course you wouldn’t want to ever “push” the trailer more than the tow vehicle is pulling Ehn, there's been some back and forth about this. To my mind, it's no different than braking while the trailer pushes. To others, it's a catastrophe waiting to happen and the sky will fall if you ...

I'm not sure that cutting springs was the correct solution here. I'm fuzzy on it, but, IIRC cutting springs does 2 things: 1 - For the same weight on the spring, it starts lower. Obviously, as you cut a ring off. 2 - For the same weight on the spring, it's stiffer (17% stiffer in your case, because ...

Hmm, not sure if you intended to do this, but... You didn't use the page I created. You created a really long page called "Operating the buck/boost converter for a low voltage CCS charging application" And as a standalone article, it's not clear what "the" buck/boost converter is...

Well... First up, keep in mind that you're probably not losing slow speed acceleration. Even with low voltage you'll still have some pep there. You'll be losing your higher speed acceleration. 22kw is enough to maintain highway speed, but not enough to get to highway speed. ... For the same cost, ar...

I am not clear on 'where' I should document this. Well like many open source projects, the Wiki is a Do-Ocracy. Those willing to do the work decide how it should be done. I would create a... nevermind... Do-ocracy, I'll just do it rather than tell you how you should do it... This page... https://op...

Again, look at the amount of info you've shared, and put yourself in the shoes of someone troubleshooting for you. Could you have troubleshot a similar task with that small of information? I don't know how to solve your problem, but I can only imagine that the people able to do this, their first que...

When in doubt, when you want people to help you troubleshoot, info dump.

Take clear pictures of your setup.

Show your settings.

we are always on the lookout for a Lead Fabricator You're aware that I "machined" a coupler by spinning it up full speed on the motor, and then easing a 7" circular saw blade into it yes? Somewhere, deep down inside, you have standards. They're there, I know they are. And mine are lo...

Btw, what was pedal #2? I hacked my straight Prius pedal into almost exactly that shape because I didn't know there was something like that out there.

Redundancy?

Double their voltage handling?

@MattsAwesomeStuff - I promised to update wikis / share what I've been doing so I'm ready to that, such as it is. I don't want to go editing the wiki without some hand holding, I don't want to screw anything up ... 1 - Every edit is tracked and reversible. So no worries. 2 - You can "preview&q...
