Instructables user [bkovac] was sick of clicking the terminal icon on his desktop whenever he wanted to launch a terminal window. Keyboard shortcuts aside, he figured the easiest way to take the tedium out of the process would be to launch terminal windows with a foot pedal.

He grabbed a pedal that he had sitting around in his workshop and took it apart to ensure the switch contacts were configured for his particular use. The wires were run to an Arduino which talks to the computer over serial using a Python script.

While the setup works just fine, it’s definitely not the most efficient or simplest way of getting the job done. In fact, we have seen other methods that are quite a bit simpler, though they lack the potential versatility of this particular modification.

Rather than simply loading a terminal window on his computer, we would love to see this pedal enhanced to perform multiple functions – at which point the Arduino would be a pretty decent choice. We would probably start out by swapping out the full-sized Arduino for a Teensy, mounting it inside the pedal. Multiple foot presses could be used to trigger different events, based upon the number of presses that occur within a given time period. It could be made even more useful by using it to trigger gesture-based events, similar to those seen in plug-ins for Chrome and Firefox.

How would you enhance [bkovac’s] pedal interface? Let us know in the comments.
