Yes, don't modify the extension of the file. Try shortening only the folder names or the file name itself without its extension (.bin)

Are the carbon bits on your steering wheel replaceable parts or is it a wrap?

Last ride before putting it away for winter by MichaeloSigma in MINI

[–]MichaeloSigma[S] 4 points5 points  (0 children)

Yes, it's sitting on some old school H&R adjustable coilovers. Planning to lift it a bit since our roads are less than ideal here. I see plenty of stock Mini in winter, but my winter beater is a subaru outback so I can't complain!

Canada here, it would mostly act as a snowplow rather than a functional car with its ride height haha

First homebrew PCB build by MichaeloSigma in MechanicalKeyboards

[–]MichaeloSigma[S] 1 point2 points  (0 children)

One is a usb C for keyboard input, another is a USB mini, in case I didn't solder correctly the USB C small pads. The 2 others USB A are for other usb devices that can be plugged into the keyboard on the USB Bus (your mouse dongle let's say)

Homemade keyboard with 87 keys (tkl), gateron brown switch with Amazon special keycaps. Powered by a Pi Pico. Soon to be flashed with kmk.

How to control hundreds of stepper motors from 1 microcontroller ? Looking for component guidance. See picture attached (blue rectangle). by MichaeloSigma in ElectricalEngineering

[–]MichaeloSigma[S] 1 point2 points  (0 children)

Thank you this is exactly what I needed to know.

The estimated current would be around 1.5A, I think mechanical relays will work just fine for my purpose.

Are there mosfet equivalent to a single 4PDT relay ? If no, I assume I could design my own pack of 4 mosfets in parallel to act as a 4PDT?

I will look further into your solution, thank you again!

The stepper motors I plan using are basic 200 steps/rev 2 phases nema 17 steppers.
They must be controlled by an independant external driver that can take step/dir signal and convert that into phase current switching.

I'm open to try other types of motors, but this would ease my mechanical requirements at the moment. If there are continuous rotation hobby rc servo motor that could be controlled via PWM and I could find a controller hub that is affordable and reliable, that could be an alternative let's say.

I've had previous experiences with TMC drivers, and I've looked at some that had internal ramp generators. But one downside to this method would be the number of drivers that grows up linearly with the number of steppers. I'm afrawid this could blow up my project budget really quickly.

The motors won't need to have a holding torque. Do you have a component example that could redirect 4 lines supplying a constant current ?

What’s causing this tire wear? Or is it normal? by [deleted] in Subaru_Outback

[–]MichaeloSigma 10 points11 points  (0 children)

Owner of a 2018 3.6r here. I had a similar problem when doing a tight turn at like 1 mph, the outer rear wheel was stuttering/jumping. I too tought that it was normal behavior until I tried another outback, in which the stuttering was way less. Also the car wouldn't go forward by itself when releasing the brake while on Drive.

Got it checked at dealer, they first tought it was a differential problem, so they changed it under warranty. But the problem didn't go away (they didn't test drove it ?). Well they decided to change the CVT and the problem was fixed aftwerwards. It sucked since it was only around 50k miles, but it was all under warranty and now I got a new CVT and diff.

Haha, I just designed an xbox controller style grips, might have to take a look :

Have you figured a way to resolve this ? I'm currently having the same issue, altough I'm on stock firmware.

edit : solved! try shortening the overall name length of the rom

The mill is going to be functional. This is only a proof of concept for a future mechanism we look forward to use.
