tinyticker 0.1.8

A tiny Raspberry Pi powered ePaper ticker.

🚀 tinyticker 🚀

size doesn't matter

tinyticker uses a Raspberry Pi zero W and a small ePaper display to periodically display a stock or crypto chart.

A flask web interface is created to set the ticker options and control the Raspberry Pi.

tinyticker uses the cryptocompare API to query the crypto price information, you'll need to get yourself a free API key. As well as the yfinance package to get the stock financial data.

Hardware

Shopping list:

• Raspberry Pi Zero WH
• One of these ePaper displays:
  • Waveshare ePaper 2.13in Black & White
  • Waveshare ePaper 2.13in Black, White & Red
  • Waveshare ePaper 2.13in Black, White & Yellow
• A micro sd card

Recommended setup

I highly recommend using comitup to setup the networking on your RPi.

• Write the comitup image to your sd card
• Boot up the RPi and setup the networking
• ssh into your RPi, you'll probably want to change the password while you're at it
• Enable the SPI interface
• (Optional) rename the hostname of your RPi by editing the /etc/hostname and /etc/hosts file
• (Optional) rename the Wifi AP name by editing the /etc/comitup.conf file
• Install the BCM2835 driver:

  curl http://www.airspayce.com/mikem/bcm2835/bcm2835-1.60.tar.gz | tar xzv
  cd bcm2835-1.60/
  ./configure
  make
  make install
  

• Install pipx depdencies:

  sudo apt install python3-pip python3-venv
  

• Install pipx:

  python3 -m pip install --user pipx
  

• Install dependency requirements:

  sudo apt install libatlas-base-dev libopenjp2-7 libtiff5 libxml2-dev libxslt1-dev
  

• Install tinyticker (the CFLAGS variable is required for RPi.GPIO to install):

  FCLAGS=-fcommon pipx install tinyticker
  

• Setup tinyticker to start on boot:

  tinyticker --start-on-boot -vv
  

  • This will write and enable 3 systemd unit files tinyticker.service, tinyticker-qrcode.service and tinyticker-web.service.
  • On boot, a qrcode linking to the flask app will be flashed on the display
• Leave a star, reboot and HODL !

Note: the Raspberry Pi zero isn't very fast so be patient :)
