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

March 4, 2023 by Dan Maloney 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.

The device has a large screen on the right hand side, a silver grate on the left, and a tray at the bottom for slotting in film.

Super 8 Film Editor Reborn As A YouTube Terminal

We love hacks that give new life to old gadgets, and [edwardianpug]’s YouTube Terminal certainly fits the bill by putting new hardware inside a Super 8 film editor.

[edwardianpug] could have relegated this classy-looking piece of A/V history to a shelf for display, but instead she decided to refresh its components so it could display any YouTube video instead of just one strip of film at a time. The Boost-Box keeps the retrofuturistic theme going by using the terminal to search for and play videos via Ytfzf.

The original screen has been replaced by an 800×600 LCD, and the yellow USB cord gives a nice splash of color to connect the ortholinear keyboard to the device. Lest you think that this “ruined” a working piece of retro-tech, [edwardianpug] says that 20 minutes would get this device back to watching old movies.

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.

Cyberdeck Contest 2022: Gibson Rev 001 Thinks Outside The Pelican Case

October 25, 2022 by Kristina Panos 5 Comments

As we’ve gushed previously in these pages, we saw an incredible turnout for our first-ever cyberdeck contest — so many cool ‘decks rolled in that it made judging them all quite the feat, and we would be remiss if we didn’t feature the favorites that, for whatever reason, didn’t make the cut. One of these is the aptly-named Gibson Rev 001 from [Gadjet].

This cyberdeck may be on the pocket-sized side of things, but don’t let that fool you, because it’s loaded with I/O and sensors galore. A Pimoroni Breakout Garden provides particle/smoke and pulse oximetry, temperature/pressure/altitude, an air quality sensor, and a UVA/UVB light sensor — plenty of feelers for judging conditions on the fly. As you might expect, the brains of the operation is a Raspi 4, which is running Twister OS.

We love the dual-display thing going on with the 7″ touchscreen and the color e-ink display — really gives it a cobbled-together-yet-polished, futuristic feel. May the rest of the post-apocalypse gadgetry have such clean lines and cheerful colors (if that’s what you’re into).

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.

2022 Cyberdeck Contest: A Wrist-Worn Deck With A Hybrid Interface

October 16, 2022 by Dan Maloney 4 Comments

You’d think that now that the 2022 Cyberdeck Contest is wrapped up, we’d stop writing about it. Sorry, but no — there were so many great entries that we just can’t help but keep focusing on them. And this wearable hybrid interface cyberdeck has a look we love so much that we can’t resist spotlighting it.

We wouldn’t go so far as to call the “hgDeck” a PipBoy, but [Igor Brkić]’s wrist-worn deck certainly bears some similarity with to the Fallout-famous terminal. In fact, the design for this one is based on his earlier hgTerm Raspberry Pi mini-laptop, which honestly would have made a great entry all by itself. But while the two version shares some similarities, the hgDeck puts a serious twist on the form factor. In the stowed configuration, the Pi Zero W puts the main display, a 3.5″ Waveshare TFT, to work using the resistive touchscreen interface. But with the flick of a finger, a motor flips the monitor up on a set of pantograph linkages, which exposes a compact Bluetooth keyboard. Another touch stows the screen and returns you to touchscreen-only operation.

There were a fair number of wrist-worn decks in the contest’s final results, and while this one didn’t win, [Igor]’s build has got to be one of the cooler designs we’ve seen, one that almost seems practical in the real world.
