question: make a video on how to mount the 14 bit encoder #16

Hello AustinOwens i love your plan using a hoverboard motor. in our communit where doing something different using that motor making a forcefeedback steering wheel. this is doable and there are people using this already also with odrive. what im interested in is how your planning on mounting your 14 bit encoder. this would be very usefull where all exploring here i also saw https://discourse.odriverobotics.com/t/hoverboard-motor-with-built-in-encoder/790 this solution. can you share more?

Hi @vospascal, sorry for the late reply. I do plan on making a video on how I am doing this, but that probably won't be out in time to be helpful for you on your project. I did see that forum post awhile ago and that convinced me to get some shielded wire for the signals, but the encoder in that forum is just an incremental encoder, whereas I am trying to set up an absolute encoder with the hoverboard motors.

I don't have anything set in stone yet, but was sketching up some ideas that involve boring out a cylinder in the hoverboard motor enclosure inline with the shaft. Because the shaft is stationary, you can mount the encoder on it while the hoverboard motor enclosure spins around it. Obviously there needs to be space for the wires to route through the hoverboard. I'm looking into how feasible it is to pipe the encoder wires through the shaft like the other signals. Noise will be an issue which is why I am hoping an independent shielded wire for the encoder will help.
