Archived: started refactoring for better architecture, full test coverage, and improving the mechanical and electrical design. However, I can’t quite make a polished exterior that I am happy with. For now, I’ve decided to archive this project with the hope that I might revisit it in the future

PiAlarm

Raspberry Pi Smart Alarm Clock. RGB light strip, buzzer, character LCD display, and web app

Tech

• Integrations
  • Plotly/Dash application to handle UI, basic HTML authentication, and managing a TInyDB instance
  • If This Then That (IFTTT)/generic HTML requests to toggle alarm on/off. Allows me to modify the alarm when not home and will automatically disable the alarm if I leave the general vicinity of my home until I return
• Electronics
  • RGB Light Strip
  • Buzzer
  • 7-Segment Display for time
  • Character LCD - shows weather and other quick information
  • (Used to also have a motorized bed shaker, but that got banned, haha)
• Box
  • Pretty janky, but easy to open and work on as a prototype. Will probably try to make something that looks nicer down the road

Initial Prototype

Prototype v2 with Box

Local Development

FIXME: Update documentation for quick start. This is probably ~32% right

git clone https://github.com/KyleKing/pialarm.git
cd pialarm
poetry install
poetry shell
python pialarm.py

First, check the pins.ini file in the Python/ directory, then proceed the test of each hardware before booting the web application for the first time.

Initialization

You will need a secret.ini file in the Python/ directory:

[IFTTT]
key = <>
[WU]
info = Weather Underground API
apikey = <>
lat = <>
lon = <>

Python packages and other libraries installed, see the script ./Python/requirements.sh

There are likely other bugs, so open an issue if you run into any trouble. This app really isn’t built for distribution and is only a personal side-project.

Hardware Test: TM1637 7-Digit Display

cd PiAlarm/Python
python .archive-python/modules/TM1637.py
# There should be a few statements printed and you can press enter to confirm each test
