It’s not earth-shattering, but MAKE blog posted this cute USB key mod where someone stuffed a Sony MicroVault into an old cassette tape. What I’d really like to see is someone stick an iPod Shuffle into one of those a cassette tape adaptors so I can listen to tunes in my parent’s old Impala.
UPDATE – Thanks to all those who sent me a million links to Mobiblue and the like, but this is what I was really looking for. (Thanks, David!)
