A DIY customizable public transit arrivals board displaying real-time transit information. Built using the open-source Transit Tracker project by Eastside Urbanism.
How to interact with it at dma.space:

http://10.20.100.80:3000/feeds- http://trans-it.local/ (http://10.20.100.80) has a page for you to view the health of the service(s) running on the Pi.
- Configure the display: Use the web configurator to customize which routes and stops are shown
The board shows arrival times for local transit agencies and updates automatically. Perfect for checking your commute before heading out!
TRMNL E-Ink Dashboard
A 7.5“ e-ink display dashboard that serves as a distraction-free information display. TRMNL uses a privacy-focused design where the device polls for updates rather than allowing external access to the local network.

- What it shows: Customizable layouts featuring calendar, weather, news, stocks, and 794+ other plugins
- Updates: The display refreshes only when new information is available, preserving battery life (6+ months on a charge)
- Plugin ecosystem: Supports integrations with Google Calendar, Home Assistant, weather stations, and community-created plugins
- Developer friendly: Create custom plugins using HTML/JSON in under 5 minutes
