# luniebox

lunibox is a RFID jukebox based on a Raspberry Pi. It is similar to the [Phoniebox](https://www.phoniebox.de) \[[https://github.com/MiczFlor/RPi-Jukebox-RFID](GitHub)\] and an upgrade of the [TonUINO (de)](https://www.voss.earth/tonuino/) 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/](https://www.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](#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`
