Hacking a RadioTape

After playing with the dc controller and a computer fan (which can move only to one direction – to it frizzed each time it moved to the other one) , I wanted to use the stepper controller but I had some problems, couldn't send to software to the controller

My Idea was to take an old radiotape and to control the Tape speed, when I open it and I thought that the motor has 4 pins I thought that it is a stepper motor, but when I tested it I became to know that it is a DC motor with controllers

therefor I hacked and plug the  controller some problems appear but at the end it worked,

the direction changes kill the tape casetes, so I made a new code but for a reason couldn't reupload the software any more

I know that you can't hear the voice changes the magnet of the speakers making the problems
