Hackinator Ian sent in a link to some pics and 'structs on his iPod shuffle + Cassette Adapter project. He writes:
it didn't come out quite as nice, but its also not quite done.
I need to mess with it some more to see how much farther down in the tape I can get it without it rubbing against the posts in the tape deck, ya know? I already killed one of the tape players on my stereo (luckily it has two) by putting too much pressure on it and keeping it from rotating while it was playing.
More after the jump. Link (.mac)
