A text only portable communication device designed for an apocolypse. This project was a competition entry for Raspberry Pi Pioneers.
Our project ended up winning 'Best Explaination'. Check out the announcement blog post (archive.org) for the other winning projects.
The repository as of when the competition was taking place can be seen on the
finaltag.
talalib.py is a Python module to interact with most of the sensors in the Tala project. You can read the documentation for this module here.
Wiring for modules may not be as they show in this diagram! We bought 2 OLED screens and the pinouts on both are different. Be careful!

- Start by flashing the latest Raspbian Lite onto an SD card.
- After it has booted type
sudo raspi-configto bring up a configuration window, selectInterfacing Options->I2C->Yes, thenInterfacing Options->Serial->No->Yes. Rebooting now is not required as we will do it in the 4th step. - Setup a Wi-Fi connection (you can skip this if you are using ethernet) by
editing this file with the command:
sudo nano /etc/wpa_supplicant/wpa_supplicant.conf. Then adding this block of code (changing the placeholders to your network) to the bottom of the file:
network={
ssid="YOUR NETWORK NAME HERE INSIDE THE QUOTES"
psk="YOUR NETWORK PASSWORD HERE INSIDE THE QUOTES"
}
- Reboot using the command
sudo reboot. - Start the automatic install script with this command
curl -sSL https://goo.gl/xPTBjq | sudo bash. - Et volia!
