Knocker, a knock based access control system for your homelab

I had hoped this would allow me to use various patterns of knocking on my desk to perform system actions. Do the cut-and-a-hair-shave knock to log in, or taptaptaptap-wait-tap to lock the screen, etc. Maybe with two microphones you could even distinguish between left and right handed knocks.

...now I'll have to make this myself.

I was thinking exactly the same thing. Or maybe a knock on the door before you enter to set stuff in your room to a certain state.

>Cut-and-a-hair-shave knock

TIL that that has a name.[1] All I ever knew it as was "the knock from Roger Rabbit".
