I just released FW16-BatteryMatrix — a little tray app that turns your Framework 16’s LED matrix into a beautiful real-time battery display.
Features:
-
Shows exact battery percentage on the 9×34 matrix
-
If WMI works on your system, you also get a smooth scrolling pulse line that moves up (charging) or down (discharging) — speed reacts to your actual charge/discharge rate
-
Right-click the tray icon to:
-
Change COM port (defaults to COM3)
-
Adjust brightness (±10)
-
-
Runs completely silently in the background (no console window)
-
Want debug output? Just add --console to a shortcut or run it from PowerShell/CMD
I’ve included both:
-
A compiled .exe (ready to run on Windows 11)
-
Full source code (batt4.py) if you want to compile it yourself or modify it
Would love a few people to test it on their machines and let me know how it goes — especially if you’re on different Windows versions, have WMI quirks, or use a different COM port.
This is my first real public application, so any feedback, suggestions, or bug reports are super welcome!
