::ABOUT
Simple walkman controller circuit, it can be used to DJ tapes but also to play a tune when you add a tape with just sounds or a pitch of some sound.
It can play back sound very slowly, at a very low speed it will start to stutter (meaning stop play stop play and so on). 
Sometimes the motor can be heard in the the sound.
The audio quality is not high, but at low speed the base is still present.
All audio is mono.
This version has extra features over the first version.
I was talking to hainbach about the first version and he gave me some tips to improve, so i thought lets give it a try. 
It took a while but i managed to get the motor sound in there and a sort of mute feature for the tape player, 
it was not possible to completely kill the sound without a huge click and this is also nice.
I also added a button to mix in the radio.

Controls:
- 1x Slide potmeter for playback speed.
- 1x Push button to Hold or Play the tape.
- 1x Slide switch to invert the function of the push button.
- 1x Button to cutt off the high frequencies of the tape player sound.
- 1x Button with volume pot to mix in the FM Radio that is build into the walkman.
- 1x Button with lowpass filter pot to mix in the magnetic fieled of the motor inside the walkman.

Power:
- 3v DC 
- 2x AA battery
