Curl the end of a wire into a hook

 

 

 

 

 

 

 

Hook it under the inside edge of the desired pogo pin

 

 

 

 

 

 

 

Force the wire between the pin and the side rail

 

 

 

 

 

 

 

Tada!  Pretty sturdy, relatively decent solution if you don’t want to order printed circuit boards to fit against the pogos and/or would prefer to avoid the headache of setting up USB control (albeit it’s probably pretty easy now that folks have made Arduino libraries and such)
