Car bluetooth stereo on the cheap
I was tired of having to hook up my phone to the auxiliary cord in my car, so I decided to make a bluetooth receiver.
The main controller board cost me $3 on aliexpress (including shipping), I picked up a cigarette lighter socket to USB plug at the local gas station.
For an enclosure, I used the tin my raspberry pi zero came in.
I covered the bottom in insulation tape to avoid shorts.
And drilled a hole for the 3.5 jack.
Testing the connections.
Adding some bling.
