js50

js50 is a collection of tools to create an interactive light installation controlled by a Telegram bot.

Setup

These setup instructions are written for the Raspberry Pi OS Lite and tested with a Adafruit RGB matrix bonnet.

After the system is flashed, login as pi over ssh. Ensure that the system is up to date.

sudo apt update
sudo apt upgrade

The different parts of the toolkit require a variety of packages to be installed.

sudo apt install git cmake libczmq-dev python3-venv python3-dev npm chromium-browser ffmpeg
sudo apt install libatlas-base-dev  libproj-dev proj-data proj-bin libfreetype6-dev
sudo apt install libgeos-dev libopenjp2-7-dev libtiff-dev libasound2-dev
sudo apt install portaudio19-dev libportaudio2 libportaudiocpp0 xvfb libwebp-dev

Next the needed sources are downloaded in the pi home folder.

cd /home/pi
mkdir lamp_data
cd lamp_data
git clone https://github.com/nathan-diodan/js50.git
git clone https://github.com/hzeller/rpi-rgb-led-matrix.git

Compiling Henner Zeller's matrix library

cd rpi-rgb-led-matrix/lib
make

and then the C interface for the python code.

cd /home/pi/lamp_data/js50/js50c
cmake -DCMAKE_BUILD_TYPE=Release ./
make
sudo cp js50/js50c/lamp_pusher /usr/local/sbin/

Preparing the python environment. The requirements are split in three parts.

cd /home/pi/lamp_data/
python3 -m 'venv' venv_lamp
. venv_lamp/bin/activate
pip install -r js50/js50py/requirements.txt 
pip install -r js50/js50py/requirements_2.txt 
pip install -r js50/js50py/requirements_3.txt

Set up the autostart with systemd.

chmod +x js50/system/auto_lamp_*
sudo cp js50/system/auto_lamp_pusher.sh /usr/local/sbin/
sudo cp js50/system/auto_lamp_player.sh /usr/local/bin
sudo cp js50/system/auto_lamp_bot.sh /usr/local/bin
sudo cp js50/system/*.service /etc/systemd/system/

sudo systemctl daemon-reload
sudo systemctl enable lamp_bot.service
sudo systemctl enable lamp_player.service
sudo systemctl enable lamp_pusher.service

Deactivate sound dtparam=audio=off in /boot/config.txt. Prepare for the first lunch:

python /home/pi/lamp_data/js50/js50py/setup.py

It will ask for the some information like your telegram bot token to create the settings.json.

Add weather icons

git clone --depth 1 --filter=blob:none --no-checkout https://github.com/erikflowers/weather-icons
