Tiny Mechanical Keyboard, Powered By Pi Pico

For some applications, smaller is better and that is precisely the thinking behind a diminutive keyboard like the PiPi Gherkin, which is designed to use the Raspberry Pi Pico as its controller. This keyboard may have only 30 keys in total, but they are full-sized for comfort and don’t let the scant layout mislead you. It has more functionality than it would seem to at first glance; the entire bottom row acts as dual function tap/hold keys, allowing the keyboard to shift layers on the fly.

This keyboard definitely has a a thoughtful layout, and we’re not just talking about the tap/shift functionality. We especially like the way the Pi Pico is tucked neatly underneath the main PCB, taking up very little room while exposing its USB connector between two standoffs for easy access without requiring an adapter, or wiring a separate plug.

If the Gherkin sounds familiar, we’ve seen it before as part of this lunchbox cyberdeck build, where the small size allowed it to take up impressively little room. The shifting might take a little getting used to, but it’s a clean design that uses full sized keys, so when it comes to small keyboards one could certainly do worse.

Lunchbox Cyberdeck Is A Tasty Build

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.
