Homebrew Stream Deck Pedal Emulates the Real Thing

Pedals are a great way to control your computer's functions. You rarely use your feet for anything else, so they can perform certain tasks, freeing up your hands. This Elgato Stream Deck Controller from [DDRBoxman] does just that.

[DDRBoxman] wanted to control Elgato Stream Deck much like the official pedal the company sells. So, a bit of hacking was in order. Using Wireshark with the Elgato pedal helped determine the actual hardware's communication method.

Once the protocol was defined, all that remained was to get the Raspberry Pi Pico to reproduce the same functionality. With the help of the tinyusb library, [DDRBoxman] was able to successfully emulate the real Elgato device. Coupled with a 3D printed pedal design from Adafruit, the project was functional and complete.

We've seen some great foot-operated devices over the years, ranging from a simple macro device to a super useful page turner for sheet music. If you've hacked your own nifty input devices, be sure to send us a message!
