My good friend and great guitarist Nzo needed a simple and heavy-duty footswitch midi controller…
This Hammond case I found on Ebay was a perfect fit for this project. 
I took to the Arduino to manage the Midi part. 
I found these great Single-pole Single-throw switches on Ebay as well. 
Just a led and a resistor, VCC/Gnd and signal wires on a strip of bakelite protoboard. 
Times five. 
Here’s for the final assembly. 
But first let’s punch holes. 
The hole on the back is for the Midi jack. 
I’m starting the wiring. 
Everything is in place. 
I soldered a cheap Nano clone on an Adafruit proto-perma board.
And here it is, back…
…and front.
