Printed Portable Computer Inspired By The Classics

These days, laptop computers are all more or less the same, at least externally. Some are thicker than others, they might come in different colors, or with a 360° hinge that lets you flip the screen around the back and use it as a tablet, but overall they’ve all got the same shape and proportions. The industry, and indeed the users, eventually agreed on the best way to make a computer portable and are now fully committed to it.

But that wasn’t always the case. In the 1980s there were a number of laptops from the likes of Toshiba, Tandy, and even IBM that took a slightly different approach to the clamshell design. These computers featured ultra-wide displays with a hinge located closer to the center of the computer, giving the machine a distinctive “trunk” in the back. It’s these classic machines that clearly inspired [Michael Mayer] to design the Portable Pi 84.

[Michael] says that the 3D printed enclosure was largely designed around the 40% ortholinear keyboard, which itself is based on the Happy-Keyboard from [Luis Alegría]. The rest apparently just fell into place, such as the fact that the 1600 x 600 Waveshare 9.3 inch display happens to be almost the perfect size to cover the keyboard below it.

Compared to many of the other custom computer builds we’ve covered, the rear compartment of the Portable Pi 84 provides ample free space for the various system components. That includes the Raspberry Pi 4 that runs the show, a UPS “hat” that powers the system via a pair of 21700 batteries, and even a set of amplified speakers. It looks like there’s still plenty of room in the back for additional gear, such as an RTL-SDR or perhaps even a cartridge slot.

A particularly nice feature of this build are the inset panels on the rear of the machine, which allow for the various ports and connectors to be reconfigured by the user without having to re-print the entire case — one could imagine a replacement panel that features a connector for an external WiFi antenna, for example. We also like the use of heat-set inserts throughout the case, which will not only make the build sturdier, but means the case can be opened and closed regularly without fear of stripping out the screw holes.

So is this a computer or a cyberdeck? It’s hard to say. We tend to think that a proper deck needs to have a more unique physical layout, and technically this form factor was actually fairly popular at one point. But whatever you want to call builds like this, we’re stoked to see them become more common and better documented. Long live the truly personal computer.

40% Keyboard Build Is 100% Open Source

[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.

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.
