luniebox

lunibox is a RFID jukebox based on a Raspberry Pi. It is similar to the Phoniebox [https://github.com/MiczFlor/RPi-Jukebox-RFID] and an upgrade of the TonUINO (de) which both are DIY versions of the popular Toniebox©. The main focus for now is to play Spotify© content, playing local files or other sources will be integrated later.

Prerequisites

You need to be familiar with ssh (Putty on Windows). For the usage of Spotify© a premium account is required.

Hardware

• Raspberry Pi (tested with Raspberry Pi 3 Model B, Zero W, Zero 2 W) [starting at ~14€]
• power supply (5V ~2.5A) [starting at ~6€]
• Micro SD card (at least 4GB) [starting at ~4€]
• RC522 RFID Reader connected to [TODO] [starting at ~1.50€]
• RFID (MiFare) cards or chips [starting at ~2€]
• a Audio Card:
  • Pimoroni Audio Amp SHIM (3W Mono Amp) [starting at ~11€] with passive speaker [starting at ~5€]
  • Pimoroni Audio DAC SHIM [starting at ~14€] with active speaker
  • Adafruit Speaker Bonnet for Raspberry Pi
  • ...something else (use custom setup!)
• (optional) MPU9250 9-axis sensor [TODO] [starting at ~1.50€]
• (optional) Waveshare UPS HAT + 2x 18650 18650 Li battery [starting at ~30€]
• some wires or dupont connectors [starting at ~2€]
• case for all above
• depending on hardware: soldering equipment

A minimal setup (Raspberry Zero 2 W, power supply, Micro SD, RC522, Cards, Audio Amp) should be about ~40€ plus case materials.

Software

• latest Raspberry Pi OS blank installation on Micro SD card (Instructions: raspberrypi.com/software/)
• WiFi connection
• ssh enabled

Optional: Headless installation

If you're using a Raspberry Pi Zero or have missing peripherals to setup WiFi and ssh please perform the following steps:

• insert Micro SD card with Raspberry Pi OS into a computer
• place an empty file called ssh into /boot folder/partioon
• place a filed called wpa_supplicant.conf into /boot folder/partition with following content

country=$COUNTRY_CODE
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1

network={
    ssid="$WIFI_SSID"
    psk="$WIFI_PASSWORD"
}

• replace $COUNTRY_CODE with upper-case country code (eg. GB or DE) and $WIFI_SSID and $WIFI_PASSWORD with your WiFi credentials
• plug card back into your Pi and connect power supply

Setup

Establish a ssh connection to your Pi:

• the Pi should be reachable under raspberrypi or raspberrypi.local in your network, if not try to find out it's IP address from your router.
• default username is pi and default password is raspberry
• Example: ssh pi@raspberrypi.local or ssh pi@192.168.2.100

⚠️ Warning: you should change the default passwort by executing passwd after login

Automatic setup

⚠️ Warning: executing scripts from the internet without checking is bad. This is only done to get things done fast. In any doubts you can perform the Manual setup and execute all commands step-by-setop to understand what's going on.

• download and excecute setup script (you will be prompted to confirm certain steps beforehand anyway)

curl https://git.bstly.de/Lurkars/luniebox/raw/branch/main/luniebox.sh -o luniebox.sh

chmod +x luniebox.sh

./luniebox.sh
