About: I am a chemical engineer from Germany especially interested in computational fluid dynamics. To balance all the theoretical work, I like to make stuff in my free time

In this instructable I am going to show you how to house a MP3 player in a cassette tape. I had the idea to build this quite some time ago, but while I was still waiting for the parts to arrive, instructable member lonesoulsurfer posted his version here.

So I decided to concentrate on other stuff and somehow forgot about it. After moving recently, the parts fell into my hands and decided to give this project an other shot, since my approach is quite different from lonesoulsurfers. My idea was to actually use the cassette tape wheels as buttons to select the songs and adjust the volume.

The cassette I used for this was broken and I decided to give it a new, more modern life.

Btw. I know that you can buy cassette MP3 players e.g. here or here , but I wanted to build one that looks completely like a normal cassette.
