New-ish to electronics and very new to DIY electronic instrument construction! I'm designing an axo enclosure currently and I'm thinking I want to take any spare GPIO leftover and connect them to some kind of socket. This would allow me to play around and experiment with different external expressive inputs whilst still having a complete device. for example I'm picturing adding an accelerator/gyro to an existing instrument that is then run through the axo as an effects patch, or attaching an additional light/distance sensor for certain patches etc.
The socket and cable will need to be cheap, easy to connect and wire, and be able to cope with some mechanical movement. A 1/4" TRS obviously works if the GPIO's are limited to two but I'm hoping to have more than two wires. I was thinking a Cat5 port/cable could work? I could then run a +/- power plus six other connections, but I have never tried anything like this.
Anyone with more experience than myself out there tried to do something similar? or have any suggestions regarding an appropriate socket and cable combo? Much obliged!
