Cool project. I made one as well but for VR, with buttons of different shapes. All in a printed case and with custom PCB.
Works great but I want to redo one, this time with more knobs. They are such a pain to turn. Maybe just 6 knobs arranged in a line.
BTW, what microcontroller are you using? And what software?
This prototype is with a Arduino Uno, but i/o ports are all used now. I’m waiting for a Mega 2560 Pro Mini to arrive. Programming it with Mobiflight!
Can you use multiplexers? I am using 5 shift registers and MMjoy to get 40 ports.
That was my initial plan, until I found out about the 2560 pro mini with all those ports available out of the box - for only $9,- …
That is an impressive amount of I/O indeed!
Looks great, and a lot like my first button box experiments. Are you using MobiFlight on the Arduino?
How it started:
How mine finished. I want to redo it though and add dual rotary encoders like yours instead of the two potentiometer knobs I have now.
Nice! Thanks for showing 😀 Yes with Mobiflight, that makes it all very doable
