This Binary Keyboard Is For ASCII Purists

So, you’re a keyboard enthusiast. The ‘board that came from Dell, HP, or whoever made your computer is just not for you. You have an ancient IBM, a decal-free Das Keyboard, or another similarly esoteric text input device. Your typing can be heard three blocks away as the unmistakable clack of bent-spring switches reverberates around you, but you don’t care because you’re in the Zone.

No keyboard can be as high-end as the one you already have, your position in the hierarchy of text entry is assured. But then along comes [Chris Johnston] with his project, and suddenly your desktop looks very cluttered. It’s a binary keypad with only a 0 key, a 1 key, and an OLED display. All input is as a series of binary bytes, so as a hardcore binary typist you’ll need to know your ASCII.

Behind the keys is an Arduino Pro Micro acting in USB HID mode, and running the code you can download from the GitHub link above. It’s a gloriously pointless input device, but we’re sure you’ll agree it has something of the 00110001 00110011 00110011 00110111 about it.

If you think you may have seen this before on Hackaday then you’re not quite right. We have had a binary keypad in the past, but that one had a return key and thus had three keys. This one’s a 2-key ‘board for binary purists.

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.
