Binary Keyboard Is The Purest Form Of Input Device

You may be a hardcore keyboard aficionado whose buckled-spring switches will be pried from your cold dead hands, but there is a new model on the street that relegates your blank-key Das Keyboard or your trusty IBM Model M to the toy chest.

The new challenger comes from Reddit user [duckythescientist], who has created a minimalist three-key binary keyboard. It features a 0 key, a 1 key, a return key, and nothing else. Characters are entered as ASCII or Unicode, and the device emulates either a QWERTY or Dvorak keyboard layout to the host computer’s USB interface. It couldn’t be a simpler layout to learn, though we’d concede that not everyone has the entire binary Unicode table memorised.

The keys are mounted in a custom 3D printed case, and the electronics come from the creator’s own “tinydev” board based on an ATtiny85. All the code is available in a GitHub repository, and there is a very short video of its Unicode ability below the break.

We’ve never had a binary keyboard here before, but we have ventured into the world of classic high quality keyboards several times. This feature on IBM capacitive keyboards for example, or a look at IBM terminal keyboards.
