Bluetooth cassette adapter

Today, with iPods that can hold entire music collections and cell phones that stream music from the Internet, the lowly cassette seems like an anachronism. [Matt] still has a cassette deck in his truck, but wanted Bluetooth connectivity for his stereo. The obvious solution was to stuff Bluetooth headphones into a cassette adapter.

Audio cassette adapters are dead-simple devices. They’re really just a tape head, stuffed into the shell of a cassette and a wire going out to a media player. To put Bluetooth into his adapter, [Matt] got a cheap pair of Bluetooth headphones and tore them apart. He was left with a circuit board, battery, and two earphones. [Matt] cut off the leads to the ear phones and wired them to the cassette adapter head. After a little bit of modifications to the case, [Matt] had a functional Bluetooth-cassette adapter.

While it’s true [Matt] could have gotten a ready-made Bluetooth cassette adapter shipped from China to his door for $10, there’s not much fun in just buying one. Kudos to [Matt] for going the home-brew route.
