Pseudonymous maker “Lame_Dave” has launched the supply code for a “Good Girder” venture, which provides an RGB LED show system to a structural girder to be able to show helpful data — together with practice occasions.
“It is loading knowledge from my MQTT server,” Lame_Dave explains of the eye-catching show, “which is a mixture of scripts and Residence Assistant. “Pleasingly all of it suits precisely contained in the girder working alongside the facet of my flat. If I transfer, the brand new place must have a girder.”

The show itself is made up of 4 RGB LED matrices, pushed by an Adafruit Matrix Portal. The place the Matrix Portal was designed to be used with CircuitPython, nevertheless, Lame_Dave took the venture in a unique route: “I couldn’t get it working reliably with CircuitPython regardless of spending weeks making an attempt,” he explains, “so it is all in Arduino.”
The Good Girder gives a variety of informational shows, one class to every of the 4 panels: Practice occasions pulled from the Transport for London (TFL) software programming interface (API); community data together with bandwidth utilization, variety of purchasers related, and knowledge utilization graphs; a Residence Assistant dashboard together with heating and temperature knowledge, air high quality, and automotive battery ranges, together with particulars on overhead flights and a monitoring system for when the automotive’s away from dwelling; and dwell climate with date and time show.

“After I began coding the [Matrix] Portals with CircuitPython probably the most I may get one to deal with was two panels,” Lame_Dave notes, “so I used to be planning to double up. However then I switched to Arduino code and ended up solely needing one to drive every little thing. Utilizing Python I might simply deplete all of the reminiscence doing easy seeming stuff with one panel.”
The supply code for the venture has been revealed to GitHub beneath an unspecified open-source license; extra particulars can be found in Lame_Dave’s Reddit thread.
