Working from home means two computers fighting over the same desk. KVM switches are not very affordable if you’re using anything more than VGA for your displays, but there are a bunch of cheap devices that will just switch your USB input devices and that is good enough for me. The only drawback is that most have the physical switch on the box itself, which means you need to have a whole bunch of USB cords sticking out of the thing in all directions within reach on your desk. I fixed this with some wire, a switch, two LEDs, and a piece of steel.

This works pretty well on the desk, and the block is nice and heavy so it stays put.
