Car bluetooth stereo on the cheap

I was tired of having to hook up my phone to the aux^iliary 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.
