#324: Cassette case

I’m driving around in a car so old that it only has a cassette player (Surely I can’t be alone in thinking that CDs and cars never worked well together?)

Anyway, I’d like to be able to play my MP3 music via my ancient car hifi (but without paying a few hundred pounds to fit a whole new system in a car that will probably only last another year).

Today’s invention would enable that, by providing a cassette-shaped module into which any MP3 player could be fitted.

The module would then be inserted into any tape deck as normal. This would be engineered to pass MP3 output signals by electrical contact with the wires leading from the (now redundant) tape reading heads. It could also act as a case to accommodate the (detached) earplugs and spare batteries.
