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

@MLE_online I've been holding off on designing/ordering PCBs for the same reason.

@JohnS_AZ @MLE_online

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.

[johns_az@mastodon.social]

@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.

@MLE_online

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

[geojeff@mastodon.social]

@MLE_online Love it, you did a great job

[niall@mastodon.nz]

@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.

@MLE_online I didn't hear whats going on with US tariffs?

[ruenahcmohr@infosec.exchange]

@MLE_online !!???
- you dont ahve "hills"
or
- thats a geared motor but it doesn't look like it?

[mle_online@social.afront.org]

@RueNahcMohr there are gears inside. I think they're planetary

[mle_online@social.afront.org]

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

[ruenahcmohr@infosec.exchange]

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

[mle_online@social.afront.org]

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

[mle_online@social.afront.org]

@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

@MLE_online 🥳

@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

[ghostsheetz@alaskan.social]

@MLE_online this is awesome. Do you have a GitHub or codeberg that you can post this on? If not, I def recommend!

[mle_online@social.afront.org]

@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
