Modular sign based on a RGB LED strip controlled by Arduino and encoder.

Hopefully this video will walk you through the build process:

NB to Bambu Lab folks:

Got several comments from Bambu Lab owners that the “V” groove tab don't fit. I just got a Bambu printer myself, and get same issue. I'm currently working on a new version, and will fix the issue there. For now, just break off the tab and it should fit.

General info:

- NOTE: I did not print all characters myself yet, so if you hit issues please let me know! - “Smart boxes” shall be used as first character, as it has space for the microcontroller. Encoder is optional, I have made files for both. - Build rest of the sign of “Regular boxes”. - Complete the sign by using a “DumbEndAngeled” . - General inside width of boxes are 30mm, those who differ from this has _XX in the name (like MM_35 and WW_38). Rear covers needs to reflect this. - I will update with more files and correction as I make them, so make sure you got latest and greatest set of files. - Code was updated and improved, get the latest and greatest from GitHub - You find wiring diagram with BOM among the pictures.

Good luck with the build - I would love to see the result!

Updates:

Update 18.09.24: Added another knob file, as I found encoders with 8mm (6mm flat) shaft. So no need for cutting it.

Update 23.09.24: Minor adjust on rear cover tabs

Update 24.09.24: Added some more symbols

Update 25.09.24: Added numbers and radio symbol

Update 27.09.24: Renamed files for Nordic letters, as names were messed up in zip downloads
