I need to buy parts from AliExpress. The scotus ruling on tariffs came just in time
@MLE_online I've been holding off on designing/ordering PCBs for the same reason.

@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.

Promising signals from the hall effect sensor wires
Nice scope there, lady.

How did you acquire the bike? Is there a āusual routeā for these rapidly expiring companiesā 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.

@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

I did it!! I hacked the e-bike motor!
It's only running off of 36 volts here rather than the 48 it's designed for because i don't have a generic 48v controller, so it's going slower than it should, but it works.
Now that I know this is possible, I will go ahead and order a 48 volt controller and a 48v BMS for rebuilding the battery pack
