DaySync

DaySync is a small e-ink display on your desk. It has only one purpose: show your upcoming events and meets from your Google Calendar.

Device

Any standard Wi-Fi enabled Raspberry Pi 40PIN GPIO (tested on 3B+) and the Waveshare 2.13 inch e-Paper Display Hat.

Getting Started

0. Clone the repo

git clone https://github.com/ArmanJR/DaySync
cd DaySync

1. Go to your Google cloud console and create a project
2. Enable Google Calendar API
3. Create OAuth Client
   • Application type: Web Application
   • Add http://localhost:8999 to Authorized JavaScript origins and Authorized redirect URIs
   • Download the token, save it as client_secret.json alongside this repo's main.py
4. Add your account as a test user on OAuth consent screen
5. Create a virtual env

python3 -m venv venv

6. Activate the env

source venv/bin/activate

7. Install the requirements

pip install -r requirements.txt

8. Modify main.py to your settings

   • Your timezone tz = pytz.timezone('America/Toronto')
   • The calendarID (more about calendars below)
   • updateInterval in seconds

9. Run the script to generate token

python main.py

A browser tab will open. Grant access to the app and close the browser after you did. A token.json file should exist now in the project directory.

10. Terminate the script (control+z) and run again via nohup

nohup python main.py > output.log 2>&1 &

If you want to terminate the script, just find the PID and kill

ps aux | grep main.py

user      12345  0.1  1.0  123456  12345 ?        S    10:00   0:00 python main.py
user      12346  0.0  0.0  123456   1234 pts/0    S+   10:00   0:00 grep --color=auto main.py

kill 12345

Calendars

By default, your main calendar is called primary. You may want to import calendars from other accounts or sources. To do so, share your calendar and replace calendarID with the one you added.

Bugs & Issues

If you have any problems running the code, please open an issue.

Improvements

• Replace nohup with a proper script execution
