A small desk-calendar with the theme of a portal chamber info.
It displays the current date, the next few events in your calendar and whether a person in your contact list has a birthday (inc. their name).
Table of Contents
The finished project on my desk:
The pie is displayed when a person in your contacts has a birthday (along with the name below it). The other three icons are currently displayed randomly.
This repo includes the software (100% python) and the STLs of the frame.
I used the following hardware:
- Waveshare 800×480, 7.5inch E-Ink display (13505)
- Raspberry Pi 3b
(The Raspi is a bit overkill if you only want to update the calendar. But since it's powered on anyways, I use it to host many other things as well. If you only want to use it for the calendar, you should take a look at the Raspberry Pi Zero series)
The prerequisites are based on this waveshare instruction to get your rapi ready for the display:
- Enable the SPI interface on your raspi
sudo raspi-config # Choose Interfacing Options -> SPI -> Yes to enable SPI interface
- Install BCM2835 libraries
wget http://www.airspayce.com/mikem/bcm2835/bcm2835-1.60.tar.gz tar zxvf bcm2835-1.60.tar.gz cd bcm2835-1.60/ sudo ./configure sudo make sudo make check sudo make install
- Install wiringPi libraries
sudo apt-get install wiringpi #For Pi 4, you need to update it: cd /tmp wget https://project-downloads.drogon.net/wiringpi-latest.deb sudo dpkg -i wiringpi-latest.deb
-
Clone the repo
git clone https://github.com/13Bytes/eInkCalendar cd eInkCalendar
-
Install requirements
sudo apt-get update # requirements by waveshare sudo apt-get install python3-pip python3-pil python3-numpy RPi.GPIO spidev # requirements by this repo sudo python3 -m pip install -r requirements.txt
-
Create config-file
cp settings.py.sample settings.py
Now edit
settings.py
and set all your settings:LOCALE: "en_US"
Select your desired format and language. It needs to be installed on your device. (In 95% of cases it already is - as it's you system-langauge. If not, take a look at the Debian Wiki)WEBDAV_CALENDAR_URL = "webcal://p32-caldav.icloud.com/published/2/XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
The address of your shared wabdav calendar. (It needs to be publicly accessible by this URL)WEBDAV_IS_APPLE = True
Is the calendar hosted on icloud?CALDAV_CONTACT_USER = "louis"
Username for logging into your CALDAV contact-list.CALDAV_CONTACT_PWD = "secret"
Password for logging into your CALDAV contact-list.ROTATE_IMAGE = True
This will rotate the image 180° before printing it to the calendar.True
is required if you use my STL, as the dipay is mounted upside-down. -
Add the start-script to your boot-process:
(You might need to adapt the path/home/pi/ePaper/run_calendar.sh
acordingly)Make
run_calendar.sh
executablechmod +x /home/pi/ePaper/run_calendar.sh
and add it to crontab, as follows:
crontab -e
and add following line:
@reboot sleep 60 && /home/pi/ePaper/run_calendar.sh
\
The STLs of the frame can be found in hardware. It's designed for 3D-printing. The two parts can be screwed together in three of the four corners.
The raspi is held in place by threaded heat set inserts.
