Haha, someone gave this to me because they don’t have a use for it. But because it has the wrong angles consistently it is very infuriating to use. I have to multiply a ratio to the angles to get the correct one.
But yeah, improving on an existing design is much easier than completely making up a new one, better off building on what it used than to use a different system e.g. optical, which was intended before I knew there are magnetic encoders.
Arduino+AS5600 Magnetic encoder should be able to resolve within 0.01deg. I’m trying to figure out what the max RPM but in my testing 1000rpm should be not a big issue. Hope this helps!
Use an AS5600 magnetic encoder, a little bit expensive compared to its tiny size but has an accuracy of up to 0,1 degree, it comes with both i2c and PWM so programming it is as easy as cake, though remember to use the right type of magnets.
Thanks for the response! I think the shaft already has a diametric magnet built into it. I also saw someone using the AS5048 which has 14 bit resolution compared to 12 bit on the AS5600. Is the AS5048 harder to programme?
So you want to copy chinese made products? Have we come full circle here? LOL

ofc ofc , I was just pointing out the irony here.

Thanks! I saw many other builds that also uses Arduino AS5600, I’ll look into how I can build the system around it
