Music on Blocks

The Music on Blocks Project creats a nice wooden remote to control your sonos music system. The Project idea is heavely based on this project: https://github.com/shawnrk/songblocks and uses some stuff for the nfc reader from adafruit: https://learn.adafruit.com/adafruit-nfc-rfid-on-raspberry-pi?view=all Furthermore the Project uses SoCo: https://github.com/SoCo/SoCo and Flask.

Setting it all up

You'll need a raspberry pi with some linux on it. I always use a raspbian image, but it also should work on other images. After installing the raspbian, I recommend to change the default password and the hostname.

Scematics

The whole box consists of a raspbery pi with a couple of different components connected to it:

• a rfid reader
  • connected over spi or uart
  • like RFID-RC522 (spi) or ...
• a rotary switch and two extra switches
• a led

RFID Reader

I used the RFID-RC522 reader. It is very cheap an works, but the antenna is not very strong.

To use it we have to enable SPI Interface in the rasperry pi settings:

sudo raspi-config
in "Advanced Options"  enable "SPI"

Installation SPI-Py (as root)

apt install python-dev
apt install gcc
git clone https://github.com/lthiery/SPI-Py
cd SPI-Py
python setup.py install

Install the LED stuff

The LED needs pigpio to correct fading. Pigpio: http://abyz.co.uk/rpi/pigpio/download.html

wget https://github.com/joan2937/pigpio/archive/master.zip
unzip master.zip
cd pigpio-master
make -j4
sudo make install

Install Music on Blocks

Download the source: (perhaps you'll have to install git, python and python-pip)

git clone https://github.com/clemenstyp/music-on-blocks.git

change into the application folder

cd music-on-blocks

The Application depends on several external libraries. The easiest way to install everything is by running the following command (perhaps you'll have to run the command with sudo):

pip install -r requirements.txt --upgrade

Once all dependanices have been installed, rename settings.py.example to settings.py and edit the file.

Basic Usage

Run python startBlocks.py to start the application. Then open up a web browser and visit http://raspberryPi:8080.

You can also use the startScript.sh, or call it from /etc/rc.local

Todo:

im rotary habe ich bei mir den pull up auf ein pull down geändert (oder andersrum - daher funktioniert der rotery nicht richtig) - den rotary konfigurierbar machen, damit der auch beim johannes läuft.
