DeskHop is a desktop switching device to control two computers with a single keyboard/mouse. What's different about this project is the ability to seamlessly switch between the two computers, simply by dragging the mouse from one desktop to the other. It supports all three major operating systems, there is no software installed on either device and it's designed with security and safety in mind.
The circuit is based on two Raspberry Pi Pico boards, chosen because they are cheap and readily available. The Picos are connected using UART and separated by a dual-channel digital isolator, TI ISO7721DR.
The case is 3d printed, without any screws and relies on a snap-fit system to both hold the PCB firmly inside the case, and hold the lid tightly sealed.
All of the schematics, gerbers, case stl, source code, binaries and documentation can be found on the project's homepage (https://github.com/hrvach/deskhop)

Jargon buster

Plain-language definitions for the technical terms used above.

PCB
A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.
UART
UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
