How to connect old tech with speakers to bluetooth?
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)
- A charger for your batteries
How does it work?
First the vintage piece of technology has to be disassembled and the speaker must be located. Furthermore the two wires exiting the speaker need to be disconnected. Next, solder those wires directly to the speaker input solder pads on the Bluetooth board.
Finding a good place for the battery is essential, maybe you could reuse the old battery compartment. Test the Bluetooth board by connecting the battery, that allows the LED to flash.
As soon as the LED is lighting up, the Bluetooth board can be connected to a phone or computer in order to play a song chosen on your device.
The board I used has a microphone suitable for Bluetooth headset mode. In case you would additionally wish to add a microphone, you could simply solder it to the microphone leads and the signal will be transmitted.
