40% Keyboard Build Is 100% Open Source

September 7, 2020 by Kristina Panos 21 Comments

[Blake]’s interest in building keyboards happened naturally enough — he was looking for a new project to work on and fell into the treasure chest that is the mechanical keyboard community. It sounds like he hasn’t built anything but keyboards since then, and we can absolutely relate.

This tidy 40% ortholinear is [Blake]’s third build, not including macro keebs. It’s based on an open source case and plate from Thingiverse, and uses an Arduino Pro Micro running the popular QMK firmware to read input from 47 Gateron blues and a rotary encoder.

We particularly like the double rainbow ribbon cable wiring method [Blake] used to connect each row and column to the controller. It looks beautiful, yes, but it’s also a great way to maintain sanity while programming and troubleshooting.

Keyboard builds can look daunting, even at 40% of standard size. But as [Blake] discovered, there are some really good guides out there with fantastic tips for hand-wiring in small spaces. And now there is another well-written guide with clear pictures to point to.

Looking to split from the standard rectangle form factor but don’t know what to go with? Divine your next clacker with this split keyboard finder.

Thanks for the tip, [jrdsgl]!

Lunchbox Cyberdeck Is A Tasty Build

June 9, 2020 by Kristina Panos 25 Comments

One of our favorite things about the cyberdeck concept has got to be the versatility of this mobile computing medium. Some cyberdecks lean toward making the user into a full-on Snow Crash gargoyle, and others are more fold-and-go like laptops. This discreet deck from [Andres Borray] looks as though it might have a PB&J and a bag of chips inside.

Instead, there’s a Gherkin. What? For the uninitiated, that’s a handmade ~~40%~~ 30% mechanical keyboard right there and it’s called the Gherkin. It has more keys than it appears, thanks to layers in the firmware. By long pressing any key on the bottom row, the entire map changes to access stuff like numbers and F keys.

This lunchbox is powered by a Raspberry Pi 4 and uses the official Pi display with the touch input enabled. Even so, there’s a baby trackball right there under the thumbs. [Andres] designed and printed panels for both sides to mount everything, and those files will be available soon along with a more detailed build log.

You can do anything you want with a cyberdeck build — it’s kind of the point. Want to program microcontrollers wherever? Get your feet wet with a cyberduck.
