I am attempting to hack this ebike motor to bypass all the proprietary stuff and what I'm seeing so far is encouraging

I've always wanted to make my own boards. Mainly because I'm a lot better with hands-on stuff than computer designing; drawing a board with a marker and copying it on my laser printer for transferring to copper clad board would be easier for me than making one on a computer program and having it made.
@kilroy_was_here @MLE_online That stuff is great and fun, provided that your design isn't too complicated. I grew up in the paint-on resist / resist pen / rub-on dry transfer methods of PCB generation. These days, I'll sit at my PC with a cup of coffee.

Nice scope there, lady.

How did you acquire the bike? Is there a “usual route” for these rapidly expiring companies’ products?

@MLE_online Love it, you did a great job

@tomjennings I think it would vary from design to design, but there are some general principles. This one actually turned out to be much simpler than I was expecting. It was just a matter of finding the hall effect sensor wires and the phase wires and getting them connected to the controller correctly.
@MLE_online @tomjennings if you can cope with fairly 'lumpy' running at low speed you don't even need to figure the halls out, just get a sensorless controller and try the phase wires in different configurations until it works.

I need to buy parts from AliExpress. The scotus ruling on tariffs came just in time
@MLE_online I didn't hear whats going on with US tariffs?

@RueNahcMohr the supreme court ruled he can't do all that tariff stuff the way he was doing it

@MLE_online Thats interesting, I thought the US president has willy-nilly I-say-so on tariffs?

@RueNahcMohr he thinks he does. The court just said he doesn't

@BenHM3 a friend's wife saw it for free on Facebook marketplace and told him to go get it. He didn't know what to do with it, so it sat in his garage for a year before he gave it to me

@Niall @tomjennings I have a 400w brushless motor from an electric lawnmower that has no hall sensors because they only ever meant it to spin the blades at a fixed speed. Something like that might be perfect for this motor

Even if this bike had worked, I probably would have done this anyway because this bike was designed to be controlled with an app on your phone and I'm not about having to use apps to use other things.
I am freeing this bike from the prison of surveillance capitalism
@MLE_online this is awesome. Do you have a GitHub or codeberg that you can post this on? If not, I def recommend!

@Ghostsheetz Oh, there's no code involved. I just removed the proprietary motor controller and swapped in a generic one.
The only real work was breaking out the hall effect sensor wires and the phase wires, and getting them connected in the right order
