Hey everyone, I took a different approach to the cassette tape speed and I found an alternative motor for driving cassette tape. I did simulations to play the cassette tape and the rpm varies between 20-50 rpm. The motor is small which is good becauseit keeps the small form factor.
Ok i'm just ordering parts for measuring RPM from EMF. Based off the overall project I think only an arduino pro mini or teensy might be used. Thats good because the cost to build this thing will dramatically decrease.
Quick question, how are you going to keep wow and flutter in check with only one spindle.
