I stole my wifes sewing machine foot-pedal for a similar project recently https://github.com/tessi/programming_paddle (code there is hacky, don't jude ;))

It's an interesting and easy project to start soldering/arduino-fiddling. Parts can be purchased with approx. $25.

In comparison to the pedal used in the vim clutch, the sewing machine pedal has the advantage of not only having an on/off state, but returning the pedal-pressure (so half-ressed and all sorts of combos are possible).

Currently, I use it for sublime-text shortcuts (cmp+p on half-press and cmd+shift+p on deep-press) or for debugging (ctrl+d to continue code execution).
