The technique is called case modding. So you took a device and built it into a cool case.

What do you need?

  • soldering iron and stuff to solder
  • pliers and screwdrivers
  • a bluetooth board (I ordered this one)
  • a battery according to your needs (for me this ,one worked)

How does it work?

First you disassemble your old piece of tech and find the speaker. You need to disconnect the two wires that are coming from your speaker and solder them to your board to the speaker input solder pads.

Second try to find a good space for your battery. I was lucky and could reuse the old battery compartment.

Test it. Try to connect to your phone or computer via Bluetooth and play a song. The board I used has a SD card slot for mp3 and a microphone for Bluetooth headset mode. If you have a microphone you could just solder it to the microphone leads and the signal will be transmitted.
