With only an old keyboard, a couple of buttons, a rubbermaid container and a few bits of scavenged wire you too can make your very own binary keyboard! All you need to do is open up the keyboard to gain access to the PCB and then use a piece of wire to touch each IC pin to each other IC pin until you find the ones that output the numbers 1 and 0.
Then with a bit of rewiring and some homebrew assembly you can complete your simple two-button keyboard. You might be asking yourself why someone would actually want a binary keyboard but when you think about it having to memorize the location of 2 keys instead of 102 is just a lot easier.
