Rpi3 with salvaged lcd from an old 3d printer acts as "server". the case was ment for another screen (2.8" touch, it was broken though) so i'll have to print a new case eventually...
i have it setup so that it loads a payload automatically when the switch is connected. on the case there are 3 buttons mounted on the back, up, down and select...
i can see and select any payload i want to use, using the buttons and the lcd. payloads are uploaded to a folder on the pi using samba for ease of use
the jig is a simple model found on thingiverse, bend basically any wire (i used a resistor, seems to short it enough to trigger anyway) into a u-shape and insert into the jig.
P.S.
I call it "The ReSwitchEr"
