Keebin’ With Kristina: The One With The Grabbity Gloves

I keep saying I need to stay away from auction sites, but then I wouldn’t have as much fodder for Hackaday, would I? As I write this, I’m waiting on a Dell AT101W, which will be my first keeb with Alps switches. Well, hopefully it has Alps SKCM salmon or black switches — according to Deskthority, it might have rubber domes. If it doesn’t keyboard, I will probably salvage the switches and build something more ergonomic. Either way, I’m thinking we need a post about Alps switches, because some people think they’re even better than Cherry MX switches.

A Better, Open Hardware Keyboard

A keyboard is the most important tool in the modern desk jockey’s arsenal but, despite this fact, millions of people suffer the $10 membrane keyboards that shipped with the computer they got a decade ago. It’s a terrible way to live your life, but for those of us who are enlightened, there’s another way: mechanical keyboards. [Mário] over at the Bit Bang Theory just built his own mechanical keyboard with his own homebrew firmware and a few interesting features that aren’t found in other open hardware keyboard projects.

The ‘from scratch’ aspect of this build is somewhat of a misnomer; the key switches used in this build were taken from a Monterey K108, and the key caps were taken from a keyboard with a Portuguese layout. Once the switches were in place and soldered up, it was time for the electronics.

While most homebrew keyboards these days use a Teensy 2 thanks to some amazing firmware and development tools that have grown up around this device, there’s not a Teensy to be found inside this keyboard. The keyboard controller is built around a PIC18F4550 and uses the USB available on the chip. Naturally, there are more than a few WS2812b RGB LEDs around the edge of the keyboard that “breathe”, run a KITT-style LED chaser, or simply display a single chosen color.

There are a few neat features in this keyboard controller that aren’t readily available with other open source keyboard firmwares. There’s a keylogger, macro recorder, and a toggle macro that will activate or deactivate a (secret) internal 8GB USB storage key. Settings are saved in the internal EEPROM.

It’s a great looking build, and something we don’t see enough of around here. In any event, it’s just one step further towards eliminating the menace of cheap keyboards, and something we hope to see more of soon.
