Cathedral Raspberry Pi Internet Radio

Details

This is my submission for the PiHackAda contest.

I used a Raspberry Pi A+, but there is no reason this wouldn't work for a Pi Zero and could probably be completed in a much smaller form factor with a Zero.

I’ve always loved the look of old cathedral radios and I decided to build my own and have it powered by a raspberry pi.

It has three modes
- Internet Radio (Raspberry Pi)
- Bluetooth In
- Aux Input

The stations I currently have programmed in are...

KSUA
KUAC
KRUA
Radio Free Brooklyn
WNYC
KCRW
WFMU
KEXP
KUTX
WICB
WMUA

These are the images for the specific stations I created. The file location on the Pi can be found inside the radio.py code.

Components

1 × Raspberry Pi I used the A+ because it was on hand, but I'm pretty sure any other model would work just fine.

1 × TFT LCD http://tinkersphere.com/raspberry-pi-compatible-components/760-raspberry-pi-22-tft-lcd-display-module-spi.html

2 × Buttons

1 × Bluetooth Module Got off amazon super cheap

1 × 3P3T Switch

thanks a lot Nick! Great project. I wish project could come with a ready list of components "basket" in websites such as adafruit...that would certainly make the life easier for a beginner like me :)

Can you tell what is the exact model of the Bluetooth module you used?

Thanks again!!

Great project. I love these old radios as well.

Not sure if you got to this snag yet but there is no audio jack on the PiZero. Lady Ada did up a video on how to get sound out of the PiZero direct https://learn.adafruit.com/adding-basic-audio-ouput-to-raspberry-pi-zero

Looks like you have plenty of room in the radio case so you could go with a USB Audio dongle. This is the solution I have used with the PiZero.

Are you sure? yes | no

Both very good options. I don't actually own a Zero at the moment, but I had an A+ on hand.

I also really like this Pimoroni option as well. - https://www.adafruit.com/products/3016
