My mum wanted to play some music from my desktop computer on her stereo(which doesnt have usb support but has stereo jack audio input) - and I was looking for reasons to hack stuff.
so i took old broken bluetooth headset (that my ex broke...bla bla ) and hacked it to include a stereo jack - and now she just plugs it in and plays the tunes(audio streaming) :)
1. Write a computer program to include voice control so she can just change music or switch of the computer off from her room using a voice command.
2.Hack the stereo to charge the bluetooth headset without unpluging it. (she probably wont let me do that lol )
Step 1: Schematic
This is the circuit diagram
Step 2: Items needed
You are going to need:
1. Bluetooth headset
3.Soldering iron and wire
5.Hot glue gun
5.General tools - e.g wire stripper
Step 3: Process
Take the cover off and be carefull with the small wires inside
Step 4: ...
strip of the casing of the stereo jack if needed to
Step 6: ...
Solder two wires to the stereo jack
- bridging the top 2 connections for left and right(black wire ) - then ground wire on third connection (white wire)
This is because the bluetooth headset has only two wires(mono output instead off stereo left and right )
*You might also want to snip off the microphone wires for privacy - but I didn't because I actually need that microphone for future hacks
Step 7: ...
Make a small hole on the headset cover and insert the stereo jack then glue it on with hot glue
Step 8: ...
Solder the wires from the stereo jack to the headset wires
be very careful because you might end up pulling the wires off like I did
Step 9: ...
Put the cover back and you have a finished product - tadaa!
Step 10: Finaly
Plug in your headset to the input(female stereo jack) of the stereo
Turn it on and pair it to your computer
Play some music
