The Binary Keyboard is a 2% keyboard that is able to replace all of the functionality of a fullsize keyboard. This repo contains the custom firmware and some schematics that can be used to construct your own Binary Keyboard.

A two-button backlit mechanical keyboard that types ASCII values, one bit at a time.

Jul 20, 2016 · 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.

Apr 17, 2017 · 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.

Taking that idea and running with it, hacker Chris Johnston came up with a keyboard with only two keys. In his setup, an Arduino Pro Micro clone takes binary input from these keys, displaying “1s” and “0s” on an OLED display as they are typed.

Jun 11, 2020 · It’s a 2 key keyboard for the most tedious typing experience ever. Basically you type in 8 bits on once you hit the 8th one it will take the value of the byte and put the corresponding ascii code and output it to the connected computer.

In a fit of inspiration, I threw this together in an evening. It is a small keyboard with three keys: 0, 1, and enter/submit. Unicode support happened a separate day. The 0 key types a "0". The 1 key types a "1". The enter/submit key types the enter key. This is the true binary mode.

Aug 14, 2021 · Using a 2-button macro-keyboard and some Arduino code, you can tap in binary and have the keyboard enter ASCII characters. View on YouTube.

Jun 26, 2016 · File for the case, PCB, and code here. The keyboard has two modes: Mode 0: the keys are '0', '1', and enter. Mode 1: press 8 bits then hit submit to type a single ASCII character. It also does Dvorak. Switches are Gateron Blues. Keycaps are from a grab bag.
