Information display of the Guild of Physics

New version of the information display made to solve its predecessor problems with maintainability and perfomance. Made with React.

New features:

• intelligent pages: page visibility and duration on the screen is easily configured
• easier to maintain(?)

Removed features:

• less emphasis on animations
• a bit less lörinä

Usage

1. Clone repo, install bun and dependencies in root and telegram bot with bun install and pip install -r requirements.txt.
2. Create a .env file using the example .env.example
3. Create the bot config in file config.py using the example example-update.json
4. Copy example-update.json to update.json
5. After that start the server with bun run server.ts and bot with python infonayttobot.py and open http://localhost:3010 in browser.

Docker

The project can also be started as a Docker container using docker compose -f docker-compose.prod.yaml up -d.

Note about Raspberry Pi configuration

To make Chromium open automatically on startup, do the following:

1. Set up Raspbian to automatically log in to the user you want. This can be done with sudo raspi-config and select "Desktop Autologin Desktop GUI" from the System options -> Boot / Auto Login. Then, find all instances of the username of the user which was used to run raspi-config in the files /etc/lightdm/lightdm.conf and /etc/systemd/system/getty@tty1.service.d/autologin.conf, and replace them with the user name you want.
2. Add the line @chromium-browser --kiosk infonaytto.fyysikkokilta.fi to ~/.config/lxsession/LXDE-pi/autostart (note the @ at the beginning), with the user that will log in automatically.
3. To prevent the raspi from going to sleep, also add the following lines to autostart (instructions from here):

@xset s noblank
@xset s off
@xset -dpms

To automatically turn of the screen during certain time of day (e.g. between 12 AM and 7 AM): sudo crontab -e and add the lines

0  0 * * * DISPLAY=:0 xset dpms force off
0  7 * * * DISPLAY=:0 xset -dpms
