2022 Cyberdeck Contest: Prototype Cyberdeck Is Anything But Questionable

October 26, 2022 by Jenny List 5 Comments

We see many projects here at Hackaday, about which their creators are unreasonably modest. We like a good cyberdeck, and we think [betaraybiff] is one of those creators from their project description for a Prototype Cyberdeck of Questionable Practical Use. It may be a prototype, but we think it could be quite a practical computer.

At its heart is the ubiquitous Raspberry Pi 4 paired with a PiSugar power supply and a minimalist mechanical keyboard. The case is the interesting part, because it’s well-designed to be 3D printed in sections with the HDMI display hinging up from above the keyboard. The Pi is open and visible on top of the deck, but this could easily be covered with another printed piece if desired.

So we disagree on the practicality, given a train journey and this cyberdeck we think we could easily crack out a Hackaday article or two. Never undersell your creations, like this one they’re almost certainly better than you think.

2022 Cyberdeck Contest: QAZ Personal Terminal

October 22, 2022 by Navarre Bartz 9 Comments

The slabtop form factor has had a resurgence in the cyberdeck community, and [Greg Leo] has designed the QAZ Personal Terminal to be about as small as a slabtop could be while still having full-sized keys.

Since the device is using a 35% QAZ keyboard as its primary input device, [Leo] has helpfully given a quick overview of how text is input in the video below. Coupled with that surprisingly popular 4:1 LCD screen we’ve seen elsewhere, this cyberdeck looks like a modern interpretation of a TRS-80 Model 100. The Banana Pi powering the QAZ Personal Terminal is running Debian with spectrwm, a tiling window manager making arranging windows a breeze with either a mouse or keyboard. The integrated mouse layer on the keyboard means you don’t need a separate mouse at all if you don’t want to spoil the 1980s mobile chic.

[Leo] has another video all about doing calculus on this cyberdeck with the math shortcuts integrated into the keyboard. Fractions, exponents, and common Greek letters are demonstrated. We can see this being a really great note-taking device for engineering and math courses if you wanted something more portable than a laptop.

It’s hard to get very far hacking without a little math. For more math-focused input devices, check out the Mathboard or the MCM/70.

2022 Cyberdeck Contest: Keezyboost40 Is A Cyberdeck Masquerading As A Keyboard

October 20, 2022 by Navarre Bartz 5 Comments

There’s something to be said for über-powerful cyberdecks, but there’s also a certain appeal to less powerful decks squeezed into a tiny form factor. [Christian Lo] has designed a cyberdeck that looks like a simple ortholinear keyboard but is running a more flexible environment.

There are games and animations you can play on QMK, but [Lo] felt that a different framework would give him more flexibility to really stretch the limits of what this Raspberry Pi Pico-powered deck could do. He decided to go with a Rust-based firmware with the keyberon library and says, “it felt like I was in control of the firmware.” While the board is using Rust for now, [Lo] says he’s open to conversations about other firmware options to achieve his goals, like a virtual pet game for the board.

The PCB is described as “bog standard” with the possible exception of placing the Pi in a cutout on the board to keep things as low profile as possible. The trade-off comes in the form of reduced board rigidity and potentially increased strain on the connections to the microcontroller.

Retro Speaker Becomes The Perfect Micro PC

October 5, 2022 by Jenny List 6 Comments

We’ve seen many cyberdecks and home built computers in our time here at Hackaday, but we’ve not seen many so tiny and so neatly built as this one from [Carter Hurd]. It takes the form of a tiny retro PC with a working display and keyboard, and we like it a lot.

The diminutive computer started life as a neat little retro themed Bluetooth speaker that a company bravely sent him for a project when he declined the chance to review it. Out came the speaker and electronics, and in went a USB Blackberry keyboard with a custom made bezel where the speaker’s keys had been.

The display is a 4″ LCD designed for a Raspberry Pi, and somewhat incredibly, he trimmed its corners to fit into the case. Making the curved CRT-style display front was achieved with vacuum form plastic, and a new display bezel was 3D printed.

A full-size Raspberry Pi fits in the base of the unit, and here he admits that it’s not the tidiest job. Perhaps a Pi Zero would have been more unobtrusive, but either way from the top and front it’s a really cute little machine. It may not be the only tiny cyberdeck we’ve seen, but it’s certainly a well-built one.

This Computer Is Definitely Not A Toy

September 30, 2022 by Jenny List 6 Comments

If you’ve ever eyed up a kids laptop and wondered whether it could take an upgrade with a single board computer, you’re not alone. [Labz] have taken a couple of Brazilian Max Steel toy computers from a decade or more ago, and made them into usable if unconventional portable computers (Brazilian Portuguese, but YouTube’s subtitle translation is your friend).

The computers are similar to the ones you may be familiar with from the likes of VTech, a QWERTY keyboard and fairly conventional form factor but with a tiny monochrome LCD and a few built-in games. In the video below the break we see both the laptop and desktop variants butchered with a rotary tool to receive new larger screens, with the laptop getting a Raspberry Pi and the desktop getting a small form factor PC. The laptop needed a 3D printed extension to make extra space, while the desktop received a PCI Express extension cable for a video card. Finally, an Arduino took care of the keyboard.

The cherry on the cake for this video comes at the end, when they find the now-grown-up kid from the original advert. Meanwhile, kids computers have featured here before a few times.

2022 Cyberdeck Contest: The Hosaka MK I Connects You To Cyberspace, Neuromancer Style

September 19, 2022 by Robin Kearey 17 Comments

It’s hard to pin down exactly what a cyberdeck is, as we’ve seen through the huge variety of designs submitted to our 2022 Cyberdeck Contest. The most basic requirement is that it is a type of portable computer, typically with a futuristic, cyberpunk-style design, but beyond that, anything goes. The original concept was introduced in William Gibson’s novel Neuromancer, where it refers to portable devices used to connect to cyberspace. The design of the ‘decks is not described in detail, but we do know that Case, the protagonist, uses a Hosaka computer which is supposedly “next year’s most expensive model”.

Inspired by Gibson’s novel, [Chris] designed and built the Hosaka MK I “Sprawl Edition” as he imagined it would have looked in the Sprawl universe. The result is an impressive piece of retro-futuristic hardware with lots of chunky tumbler switches, exposed metal screws, and even a shoulder strap. Processing power is supplied by a Raspberry Pi, with input and output happening through a 7″ touchscreen. There’s also an ESP32, which controls a set of RGB LEDs on the back as well as an FM radio module.

The Hosaka’s functionality can even be extended by adding modules to the side, which will snap into place thanks to a set of neodymium magnets integrated into the housing. The whole case is 3D printed, and a full set of .stl files is available for download, although [Chris] warns that the larger parts might be too big for some 3D printers: the whole thing barely fits inside his Prusa MK3s.

We’ve seen several cyberdeck creators that aimed to recreate Gibson’s vision: the XMT-19 Cutlass is one example, as is the massive NX-Yamato. If you’ve designed your own, be sure to submit it to this year’s contest.

Keebin’ With Kristina: The One With The Hexagonal Keyboard

September 15, 2022 by Kristina Panos 16 Comments

Well, I didn’t mean to take the whole summer off from Keebin’, it just kind of happened that way. You’d think it would have been #13 that tripped me up, but we ain’t even there yet — this is only the twelfth edition. I kept thinking I should write one and it just wasn’t happening, until I got a tip from [s.ol bekic] about their stunning hexagonal keycaps and the journey toward making an open-source 12-key macropad featuring same.

But let’s back up a bit. Originally, [s.ol] designed a totally sick hybrid MIDI-and-typing keyboard from scratch, which you can see in this short video. It glows, it splits in half, and it snaps back together again quite satisfyingly. And you probably noticed the hexagonal keycaps that look like they might be printed or milled, or perhaps even printed and then milled.

In actuality, [s.ol] threw all the processes at this keycap project — milling, molding and casting, and 3D printing. None of them worked well enough to get much past the prototype stage, but in the end, [s.ol] joined forces with fkcaps.com to create and offer an injection-molded version that I’d really, really like to rock my fingertips around in. Good thing I can pick some up for cheap.

Of course, the real process was all the learning [s.ol] did along the way — both in the early days of making the hybrid keyboard, and after teaming up with fkcaps to make the keycaps and the accompanying macropad into real products. And that was after all the design work it took to get this newfangled honeycomb configuration right.

In case you’re wondering, these are meant for only Kailh chocs, but no matter the switch, the spacing is really important because of all the possible points of friction introduced by the design. Be sure to check out the keycap docs page, macropad docs page, and this gallery of keycaps and macropads.
