USB Foot Switch

This simple foot switch simulates a USB input device via a Raspberry Pico 2. Depending on the programming, it can be used to send a single letter, an entire text, or change the volume, for example. The possibilities here are almost limitless.For this project, I was satisfied with simulating a keystroke as on a keyboard (otherwise it would be cheating, unfortunately😅). Assembly is relatively simple:Insert the M3 threaded inserts on the side.Solder the Raspberry Pico to a Cherry switch. Please lay the wires beforehand!Secure the Raspberry with the four M2 screws in the lower part, then insert the Cherry switches and springs. Please note that 3D printing has its limitations!Connect the upper and lower parts of the foot switch with the M3 screws.Use the cutting template (printing plate 3) to cut the griptape and stick it onto the upper part. Whether you need one at the bottom depends on the surface on which you will later use the switch.Next, the Raspberry must be programmed:➡️Open the of
