The article introduces DeskHop, a fast desktop switching project that allows users to switch between two computers using a keyboard shortcut or by moving the mouse pointer between monitors. The project is completely free and open source, with no noticeable delay when switching, and works with Linux, macOS, and Windows. The device acts as an intermediary between the keyboard/mouse and the computer, establishing and maintaining connections with both computers at once. The project also features a 3D printable snap-fit case and full Galvanic isolation between outputs.
