In a demonstration of how to improve productivity when using a computer, Jan Herman uses foot pedals as an alternative to keyboard keys, enabling the user to plug a foot pedal into the various keys they might need when undertaking different tasks.
Rather than using a USB interface chip, he opts for a more traditional approach, removing the components from a standard USB keyboard and wiring them up to 3.5 mm jack connectors, before placing them in a metal project box.
Herman’s choice of using 3.5 mm jacks enables the user to easily change and adapt the foot pedals to suit different applications, with the project being easily configurable.
This simple but effective method can help improve ergonomics and efficiency when working at a computer for long periods.
