So I'm using a cheap BT audio module to recieve audio from my phone and feed it in to my cassette deck.
All this is built in to the insides of a cheap tape adapter that has a wire running from inside it for power.

How would /diy/ provide 3.6v and less than 55mA to a chip inside a cassette? Rechargable battery? Harness the cassette's spinning power with a motor?
