Ah! Glediator, wish that was open-source.
Really cool project BTW, I’m inspired enough to try and replicate your work. Couple of questions:
How did you solve the “serial maintenance” issue? Did you use connectors between strips so you have to replace a strip if one LED in it fail? Or are you using connectors between any two LEDs?
How does RS485 solve the signal-line distance problem? does your LED controller board connect to several short data lines instead of 1 really long one? How do you clock sync between several data lines?
