Self-contained quick project for a desk stock summary page using a Pimoroni InkyWhat eInk display and Raspberry Pi Zero W. I got the eInk capable of drawing red.
Intended as a gift, so the project is intended to be done reasonably quickly and configuration after 'deployment' should be possible remotely and with minimal fuss.
Pretty standard setup:
-
Install latest minimal Raspbian and flash to a SD card with Etcher.
-
Setup the image with SSH enabled, and add WiFi credentials.
-
Configure a new hostname
stockticker.localin this case. -
Set a new password, etc.
-
Run
sudo apt update && sudo apt upgrade. -
I used Pimoroni's quick setup
curl https://get.pimoroni.com/inky | bashone-liner to get that side setup (its mostly doing things like installingpip,numpyand configuring SPI mode on the Pi). It takes a very long time to run. -
A reboot is required at this point.
-
Clone this repo into the home directory
git clone https://github.com/Scottapotamas/paperstonks.git -
Use
crontab -eto edit the cron jobs. Add*/5 * * * * /home/pi/paperstonks/refresh_stonks.shand@reboot /home/pi/paperstonks/refresh_stonks.shas new lines.
Before giving the display as a gift, setup the dispay to have a nice 'welcome' image. Run the prep_display program with python gift.py to draw a dithered image.
- Provide power and allow the system to boot.
- The eInk display should display content when ready (system assumes a valid wifi/network connection is present).
- Pulls stock info from Yahoo finance and formats the output for display on the eInk.
The Pi will pull this git repo periodically.
