I bought this little AM radio a few years ago intending to turn it into a Bluetooth speaker. I think they are from the 1970's or 80's.
I used a super simple circuit, just a DW-CT14+ Bluetooth amp and a now discontinued SparkFun Power Cell. The batter can also be driven using this Icstation TP4056. I also 3D printed a little mount in there to keep the USB port steady.
