Make a cassette loop for about 6 seconds

Instructables has instructions on how to make a tape cassette that loops.

6 second cassette tape loop instructions

I just dusted off an old tapedeck I was going to sell and decided against it (since it didn’t look like it’d make more than 10 bucks or something) so I will try to find some time to make one of these cassette loops.
