Created a first prototype rendering for the Raspberry Pi version of the project the other day. It's funny how doing one part of a task can inform elements of another.

Initially, I was in favor of using individual inputs from the control units into the base, but now I'm not so sure. It would make the actual creation of controllers more approachable for the users, but a straight I2C approach would be much cleaner. The main issue with going that route that I am still struggling with is the added complexity and expense of needing some sort of microcontroller in the control device to conduct the I2C communication.

Also, looking at it in 3D, the header location/count will very likely change, but it will work for testing purposes as is.

Work goes on though, with the initial prototype done, next step will be to print a copy to see how it will come out.

Wish me luck!
