TRS-80 Model 100 Inspires Cool Cyberdeck Build, 40 Years Down The Line

March 4, 2023 by 19 Comments

The TRS-80 Model 100 was a strange beast. When it debuted in 1983, it resembled nothing that was available at the time, and filled a gap between desktop computers and the mostly-not-invented-yet laptop segment of the market. Collectors covet these machines, but they’re getting harder to find four decades later. So, if you want one, you just might have to roll your own.

Honestly, it doesn’t appear [Roberto Alsina]’s purpose here we to recreate the Model 100 per se, but rather to take inspiration from its oddball form factor and experiment with the latest components. The design elements from the original that [Roberto]’s creation most strongly echo are the screen with the extreme landscape aspect ratio and the somewhat compressed keyboard. The latter is based on the cheapest mechanical 65% keyboard available, while the former is a 1920×480 LCD display intended for automotive applications. The display seems like it put up a fight, between its need for a custom HDMI cable to connect it to the Radxa Zero SBC under the hood as well as the custom kernel needed to support it.

Along with a USB hub for IO and some 18650s for power, everything went into a 3D printed case with considerably sleeker lines than the Model 100. It’s worth pointing out that [Roberto] didn’t have much experience with design or 3D printing when he kicked off this project. We love to see people stretching their skills like that, and we think the results are great in this case. We’ve seen a lot of Model 100 retrofits and brain transplants, but this may be the first time we’ve seen a build quite like this.

Retro Computer Enclosure Without The Sacrifice

January 30, 2023 by 29 Comments

The unique look of early desktop computer systems remains popular with a certain segment of geekdom, so it’s no great surprise when we occasionally see a modern hacker or maker unceremoniously chuck 40+ year old electronics from a vintage machine just to reuse its plastic carcass. We try not to pass judgement, but it does sting to see literal museum pieces turned into glorified Raspberry Pi enclosures.

But with a little luck, perhaps the Retro Wedge Computer case designed by [AndyMt] will be able to save a few of those veteran computers from an unnecessary lobotomy. As the name implies, this 3D printable model is designed to resemble “wedge” desktop computers such as the Atari ST, TI-994A, and Commodore 128. But don’t be put off by its considerable size — the model has been chopped up so no piece is larger than what can fit on a fairly standard 230 x 230 mm print bed.

2022 Cyberdeck Contest: Prototype Cyberdeck Is Anything But Questionable

October 26, 2022 by 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 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 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 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 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.
