Woop, PCBs have arrived! I got a stack of 10 in a nice red colour:
My next course of action is to order the components for it and solder up a few boards!
There's also still a bit of work to be done on both the firmware and software. If you're interested follow my github projects:
The firmware & software is what will make this project special; it will use advanced colour models that will allow accurate colour reproduction and animation. It will also be able to respond to audio and external triggers!
Looking back on my design now I kind of wished I added room for an RGB colour sensor, so it could automatically calibrate the colour models. Alas I'll probably have to implement some sort of separate module to do this, or rely on dodgy chinese datasheets!
