box

A raspberry pi based streamer box

Get Started!

PI OS

Our Raspberry Pi Setup Guide walks you through setting up your pi to attach to a wireless network and start streaming ARTxFM!

Optional code to do cool stuff

"checkin -- Run periodically to report status and turn LED on/off. checkin.py

"voulmed" -- Program to monitor the volume pot and adjust the audio output level. See VOLD

"ledctl" -- Program that can turn our awesome LED on and off. See LED

Admin/Web Interface

The boxes we are building at ARTxFM are designed to checkin with a server.

See boxmaster

Features of hypothetical ARTxFM box

1. Connects to local wifi and streams ARTxFM.
2. Audio output through 3.5mm stereo jack
3. Standard 2 prong plug for power.
4. Has LED that lights up when some sort of ARTxFM special event is going on.
5. Periodically checks in with a web service to find out if it should update itself or turn on/off its special event LED.
6. Basic web UI that lists all the known boxes with their check in history.

Originally we had a volume control knob, but in practice this is not useful. Just having the pi on max volume is fine for hookup to all the amplifiers that we have tried.
