2023 Cyberdeck Challenge: Crosberry Pi Loves Lo-Fi Hip Hop

July 22, 2023 by Kristina Panos 1 Comment

As far as we can tell, the only real selling point that any portable record player offered was, well, its portability. To be clear, the sound is never that great. But perhaps a selling point for this crowd is that they usually come in hinged cases with handles, and you know what that means — cyberdeck that thing!

[Mx. Jack Nelson] started gutting this Crosley CR40 record player to make a Raspberry Pi housing, but it quickly turned into a cyberdeck project with the addition of a 10.1″ portable monitor, a Planck ortholinear keyboard, and a gutted trackball mouse.

We love that [Mx. Jack Nelson] made use of the Crosley’s original speakers — this was the wife’s idea! — as well as the volume and tone knobs. But our favorite part has to be the clear acrylic top that both protects the electronics and provides a platform for the keyboard and mouse buttons. Be sure to check out the demo video after the break.

Bringing A Baofeng Into The Cyberpunk 2077 Universe

July 14, 2023 by Dan Maloney 10 Comments

You’ve got to love the aesthetics of dystopian cyberpunk video games, where all the technology looks like it’s cobbled together from cast-off bits of the old world’s remains. Kudos go to those who attempt to recreate these virtual props and bring them into the real world, but our highest praise goes to those who not only make a game-realistic version of a prop, but make it actually work.

Take the Nokota Manufacturing radio from Cyberpunk 2077, for instance. [Taylor] took one look at that and knew it would be the perfect vessel for a Baofeng UV-5R, the dual-band transceiver that amateur radio operators love to hate. The idea is to strip the PCB out of a Baofeng — no worries, the things cost like $25 — and install it in a game-accurate 3D printed case. But this is far from just a case mod, since [Taylor]’s goal is to replace the radio’s original controls with something closer to what’s in the game.

To that end, [Taylor] is spinning up an interface to the stock radio’s keypad using some 7400-series bilateral analog switches. Hooked to the keypad contacts and controlled by a Mini MEGA 2560 microcontroller, the interface is able to send macros that imitate the keypresses necessary to change frequencies and control the radio’s settings, plus display the results on the yellow OLED screen that seems a dead-ringer for the in-game display. The video below shows some early testing of the interface.

While very much still a work in progress, we’ve been following [Taylor]’s project for a week or so and he’s really gaining some ground. We’ve encouraged him to enter this one in the Cyberdeck Challenge we’ve got going on now; it might not have much “deck” going for it, but it sure does have a lot of “cyber.”

2023 Cyberdeck Challenge: YAHRC Takes Its Power Seriously

July 9, 2023 by Donald Papp 5 Comments

Cyberdecks are all about custom builds, and [f4drj]’s YAHRC (Yet Another Ham Radio Cyberdeck) takes its ruggedization and power seriously. There are some great power management features, and the enclosure even has a layer of RF shielding.

YAHRC is a Raspberry Pi-based build with a generously-sized screen that tucks a small Bluetooth keyboard into a storage area for input in a pinch. Everything is secured behind custom panels, and behind those panels are some really great build details. There’s active cooling via fans, an SSD for data, and [f4drj] even made a custom riser for the GPIO header by soldering together a couple of headers to act as an extender. This exposes the GPIO header right beside a clear area for prototyping, with easy access to USB ports next to the screen in the top panel.

2023 Cyberdeck Challenge: Reviving The First Notebook Computer

July 4, 2023 by Jenny List 7 Comments

At first sight upon seeing [Don]’s HX2023 cyberdeck project one might be sad at the destruction of a retrocomputer, but in fact its classic Epson shell comes from a pile of spare parts left after restoring many other of the classic HX20 notebook computers to working order. The result stays true to the original but gives us so much more in the shape of a Raspberry Pi, and it’s worth cracking it open to see what components make this happen.

The first impression from the pictures is how tidy it all is, with the various USB-based boards contained on a large piece of perfboard spanning the whole case. As well as a USB hub and UPS board there’s an M.2 SSD interface and an audio board, and a DSI color TFT screen neatly fitted in place of the original monochrome item. Finally, there’s an Adafruit keyboard matrix interface board, allowing the use of the Epson’s original keys.

We like this conversion, because it manages to preserve a lot of what the original Epson had that made it great. We’re reminded of a cyberdeck inspired by the other great 8-bit notebook, the TRS-80 model 100.

Jack In, The 2023 Cyberdeck Challenge Starts Now

June 20, 2023 by Tom Nardi 17 Comments

The modern laptop is truly a masterpiece of engineering, craming an incredible amount of processing power into a thin and lightweight package that can run for hours on its internal batteries, all for just a few hundred bucks. Combine that with the ubiquitous smartphone, and it’s safe to say that the state of mobile computing has never been better.

Despite this, over the last several years we’ve watched cyberdecks go from a few one-off examples to a vibrant community of truly personal computing devices. While there are some exceptions, most of them are larger, more expensive, and less portable than what’s available on the commercial market. But that’s not the point — a cyberdeck should be a reflection of the hacker that built it, not the product of a faceless megacorp.

Which is why we’re excited to officially announce the 2023 Cyberdeck Challenge, starting now and running all summer through to August 15th.

Whether it’s a ridiculously over the top wearable that wouldn’t look out of place in a cyberpunk anime or a pocket-sized gadget that you operate with a handful of unlabeled buttons, we want to see it. All we ask is that it be a functional device capable of some useful amount of computing, anything beyond that is up to you. Turn in one of the top three designs, and you’ll earn a $150 USD DigiKey shopping spree, just what you need to pack a few extra bells and whistles into your rig.

A Parts Bin Cyberdeck Built For Satellite Hacking

March 12, 2023 by Tom Nardi 10 Comments

While there’s little in the way of hard rules dictating what constitutes a cyberdeck, one popular opinion is that it should be a piecemeal affair — a custom rig built up of whatever high-tech detritus the intrepid hacker can get their hands on, whether it be through trades or the time-honored tradition of dumpster diving. It should also be functional, and ideally, capable of some feats which would be difficult to accomplish with a garden variety laptop.

If you’re looking for an example that embraces these concepts to the fullest, look no further than the Spacedeck built by [saveitforparts]. Combining a touch screen all-in-one computer pulled from a police cruiser in the early 2000s, an RTL-SDR, and the contents of several parts bins, the rig is designed to work in conjunction with his growing collection of motorized satellite dishes to sniff out signals from space.

As you can see in the build video below, the design for this mobile satellite hacking station was originally very different, featuring considerably more modern hardware with all the buzzword interfaces and protocols you’d expect. But [saveitforparts] couldn’t get all the parts talking satisfactorily, so he went in the closet and dug out one of the surplus police terminals he’d picked up a while back.

He didn’t have the appropriate connector to power the machine up, but by cracking open the case and tracing out the wires, he figured out where he needed to inject the 12 V to get it spun up. From there he installed a new Mini PCI WiFi adapter, loaded up an era-appropriate build of Linux, and got the standard software-defined radio tools up and running.

What really sets this build apart are the two custom panels. The top one offers access to the various ports on the computer, as well as provides a sort of switchboard that connects the RTL-SDR to various onboard filters. The lower panel includes the hardware and controls necessary to aim different styles of motorized satellite dishes, as well as a USB hub and connector that leads into a commercial satellite meter tucked into the case.

At the end of the video [saveitforparts] demonstrates the various capabilities of the Spacedeck, such as the ability to pull in imagery from weather satellites. Considering the sort of satellite sniffing we’ve seen him pull off in the past, we have no doubt this machine is going to be listening in on some interesting transmissions before too long.

Low Power Challenge: The PotatoP Runs Lisp For Months Without Recharging

March 6, 2023 by Robin Kearey 53 Comments

A common complaint among laptop users is that while battery technology has vastly improved over the past decades, a simulltaneous shrink in form factors has meant that a typical laptop today doesn’t last much longer on a battery charge than one from the early 2000s. But it doesn’t have to be that way, as [Andreas Eriksen] demonstrates with his entry for the Low Power Challenge. The PotatoP is a portable computer that should be able to run for about two years on a single battery charge, and can be topped up through an integrated solar panel.

Granted, it doesn’t have the processing power of even the cheapest laptop you can buy today, but it’s perfectly fine for [Andreas]’s use case. He’s a Lisp hacker, and a Sparkfun RedBoard Artemis can run uLisp just fine on its 48 MHz Cortex-M4F processor. The operating environment is very basic though, even requiring [Andreas] to write his own text editor, called Typo, to give him editing luxuries like backspace functionality and a movable cursor.

The Artemis board is very power-efficient by itself – typical power consumption is less than 1 mA. [Andreas] added a simple monochrome black-and-white LCD screen capable of displaying 53 columns of text, plus an SD card reader for data storage, and designed a sleek 3D-printed case to hold everything together. When running a typical piece of code, the entire system uses around 2.5 mA, which translates to about 125 days of continuous run-time on the beefy 12000 mAh lithium battery. Add a bit of solar power, plus a more realistic eight-hour working day, and the two year runtime estimated by [Andreas] appears entirely reasonable.

This has to be one of the most power-efficient portables we’ve ever seen, and one running Lisp at that. Despite its age, Lisp keeps popping up in interesting custom computers like the Lisperati1000 cyberdeck and The Lisp Badge.
