    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.

    I just received 5PC pkg today. I'm just waiting on the giant book of resistors/caps to come in the mail next week.

      The tape has to move at a constant 4.76cm/s rate. Based off the protoype design it didn't include the tachometer to measure the linear speed.

      Im going to list 3 ways it may play correctly

      1. No tachometer, uses a microcomputer for reading the cassette tape and use software to stabilize the changing play speed
      2. Add a tachometer to read the 4,76cm/rate but the design becomes bulkier with extra parts.
      3. We discover a new way to play a cassette tape at the right speed somehow.

    Thanks to @Morning.Star for recommending a pre-amp for the Casette Tape Head. A Youtube video a google search later

    I ran out of 0805 cap SMDs just looking around for some assortment packs on ebay.

    So far I was looking for a Square Card reader in my room, since they use tape heads. I found a 1st gen Square card reader and a 5th gen square card reader (which broke into tiny pieces when i tried taking it apart ). Based off Google search this 1st gen tape head reads mono audio. The next part is to design and assemble an amplifier to play audio off the cassette.
