Manufacturing engineer and maker Hrvoje Čavrak has constructed a instrument that goals to interchange often-unreliable software program keyboard-and-mouse sharing instruments with a extra sturdy {hardware} resolution, powered by a pair of Raspberry Pi Pico microcontroller boards: the DeskHop.
“Did you ever discover how, within the loopy world of tech, there’s at all times that one quirky little mission attempting to resolve an issue so area of interest that its solely opponents is perhaps a left-handed screwdriver and a self-hiding alarm clock,” Čavrak writes in regards to the origin of his system.
“All I wished was a means to make use of a keyboard shortcut to rapidly swap outputs, paired with the power to do the identical by magically transferring the mouse pointer between screens. This mission allows you to do each, even when your computer systems run totally different working methods!”

DeskHop is impressed each by conventional keyboard-mouse-and-video (KVM) gadgets and software-based enter sharing instruments like Barrier, Enter Leap, or Synergy. The concept is straightforward: having two computer systems with two unbiased screens however one keyboard and mouse, they assist you to swap the enter gadgets between the 2 — within the case of Synergy and comparable, as simply as transferring your mouse pointer to the sting of 1 monitor and seeing it flip onto the opposite.
Instruments like Synergy, although, depend on cooperation from the working system — and, on the earth of Linux, the transfer to Wayland has rendered many software-based options ineffective. Enter DeskHop: a completely machine-independent {hardware} resolution, nearer to a standard KVM however tailor-made for the Synergy-style use-case — and, like Synergy, activated as rapidly as transferring the mouse pointer from the sting of 1 show onto the opposite.
“The system acts as an middleman between your keyboard/mouse and the pc, establishing and sustaining connections with each computer systems without delay,” Čavrak explains. “Then it chooses the place to ahead your mouse and keystrokes to, relying in your choice. Keyboard follows the mouse and vice versa, so simply dragging the mouse to the opposite desktop will swap each.”
If it took a button-push to activate, the system could be no higher than a USB swap — however DeskHop is smarter: when the mouse cursor hits the far fringe of the primary machine’s monitor it routinely switches to the second machine, even matching the vertical place between machines.
The {hardware} could not be less complicated: a single-sided provider board carries two Raspberry Pi Pico microcontroller boards, one for the keyboard and one for the mouse. As all the things occurs in {hardware}, it is operating-system agnostic: in case your machines can take USB keyboards and mice, they’re going to work with DeskHop.
Čavrak has launched the DeskHop beneath the reciprocal GNU Common Public License; design recordsdata, supply code, and a 3D-printable case can be found on the DeskHop GitHub repository.
