 Initial proof of concept with breadboard, everything works perfectly.

+Then perfboard implementation. A first for me, quite the hassle, I probably didn't go the easiest way with the solder traces and then the cables on the back. A multimeter with continuity mode is a must have to ensure there's no short between traces.
 Next time, solder traces are not worth the time and headache and cables should just be soldered through holes with a single solder joint to the next hole.
