Heavyweight Cyberdeck Is In A Class Of Its Own

Inspired by other builds he’d seen online, [BlastoSupreme] decided to build his very own cyberdeck. There was only one problem: he’d never designed and assembled anything like this before. Wanting to avoid any problems down the line, he reasoned that the safest approach would be to make it so big that he wouldn’t struggle to fit everything inside. Some may say the resulting NX-Yamato, named for the most massive battleship ever constructed, ended up being too large. But that’s only because they are afraid.

A finish like the Yamato’s doesn’t come easy.

In his write-up on The Cyberdeck Cafe, a site dedicated to the community sprouting up around these futuristic personal computers, [BlastoSupreme] describes building this cyberdeck as something of a transformative experience. Looking at the incredible effort that went into this project, we can believe it. From the intricate CAD work to the absolutely phenomenal finish on the Yamato’s 3D printed frame, there’s not a cut corner in sight.

That’s right, nearly every component of this cyberdeck was conjured into existence by squirting out hot plastic. About two kilograms of it, to be precise. It was printed in vertical chunks which were then assembled with adhesive and screws. This modular construction technique allowed [BlastoSupreme] to build what he believes to be the largest cyberdeck ever made. Sounds a lot like a challenge to us.

Admittedly, the massive internal volume of the Yamato is largely unused; all that’s inside it right now is a Raspberry Pi 4 and a X705 power management board that allows the deck to run off of 18650 cells. Of course, all that space could easily be put to use with additional gear or even a larger and more powerful Single Board Computer (SBC) such as the Atomic Pi. There’s even a dedicated compartment in the side for snacks, so no worries there. As [BlastoSupreme] puts it, all that empty space inside is a feature, not a bug.

Plenty of room inside for whatever hardware you want to take with you into the Sprawl.

In the nearly two years that have passed since we first came across one of these Neuromancer inspired builds, we’ve been absolutely blown away by the increasing scale and complexity of these extremely personal computers. Since it seems there’s only a fairly loose idea of what a “proper” cyberdeck should look like in the canonical sense, these builds have been free to fill in the blanks with some pretty outlandish designs. Some of which have earned William Gibson’s personal seal of approval.

A Thermal Camera With A Vintage Twist

Nowadays we often value the superb design of vintage technology. It is, therefore, laudable when a broken piece of old electronics is given a new purpose. These types of builds are exactly [Martin Mander’s] cup of tea as he confirmed by turning a 1979 Apollo microwave monitor into a thermal camera (video embedded below).

Intrigued by its unique design, [Martin Mander] picked up the original microwave monitor at a secondhand sale, although the device was not exactly in mint condition. Supposedly this type of detector was used to monitor the exposure of personnel to microwave radiation in an industrial environment.

After removing all the guts, he replaced them with a Raspberry Pi Zero W, Adafruit thermal camera, 1.3″ TFT display, and a USB battery pack. It is especially nice that [Martin Mander] was able to mount all the components without relying on 3D prints but instead, he hand-carved some custom panels and brackets from waste plastic.

The software is based on Python and automatically uploads the captured images to an Adafruit.IO dashboard. With 8 x 8 pixels the resolution of the sensor is not great but by using bicubic interpolation he was able to convert it to a 32 x 32 image which was enough to take some interesting pictures of his cat and other household items.

It is also worthwhile to check out some of [Martin Manders] other retro-tech mods like his cassette Pi IoT scroller.

A Fantastic Raspberry Pi Handheld Just Got Better

Last year, we brought you word of the MutantC by [rahmanshaber]. The Raspberry Pi handheld was more than a little inspired by the classic T-Mobile Sidekick, with a sliding display and physical QWERTY keyboard. The design was a little rough around the edges and missing a few key features, but it was clear the project had a lot of potential.

Today, we’re happy to report that [rahmanshaber] has officially released MutantC_v2. It looks like the new version of this handheld, perhaps more properly categorized as a ultra-mobile PC (UMPC), successfully addresses a number of the shortcomings found in the original; so if you held off on building one last year, you might want to start warming up the 3D printer now.

The major improvement over the original is the inclusion of a battery, which makes the device truly mobile. This was something that we mentioned [rahmanshaber] was working on back when he released the first version, as it was easily the most requested feature from the community. We certainly wouldn’t say a miniature handheld computer is completely useless if it has to stay tethered, but there’s no arguing that being able to take it on the go is ideal.

This upgraded version of the design now officially supports the Raspberry Pi 4 as well, which previously [rahmanshaber] was advising against due to overheating concerns. Slotting in the latest-and-greatest edition of every hacker’s favorite Linux single board computer will definitely kick things up a notch, though we imagine the older and less power hungry iterations of the Pi will be plenty for the sort of tasks you’re likely to be doing on a gadget like this.

If you like the idea of having a diminutive Linux computer within arm’s reach of your bench but aren’t necessarily committed enough to build something like the MutantC, there are certainly simpler designs you can get started with.

Warm Up To Cooking With A Recipe-Randomizing Toaster

Did you get a thermal printer when they were hot stuff, but then your interest cooled when you couldn’t decide what to do with it? Something similar happened to [Sunyecz22], and the poor printer sat unused until that magical day when the perfect use for it popped up — a random recipe receiver in the form of a toaster.

[Sunyecz22] was tired of searching for recipes every week before going to the grocery store. Between the millions of recipe options on the internet and the 1000-word essays that precede them all, the process was like a part-time job. Now all they have to do is push the little lever down and wait for a recipe to get toasted into some thermal paper. It doesn’t print the full recipe, only the essentials, and we love that. You get the name, the prep time, a rating, and a QR code that links to the recipe page.

This toaster runs on a Raspberry Pi Zero W that fetches recipes using the Spoonacular API and sends the deets to the printer. The lever makes use of some old pen springs to activate a limit switch and start the recipe-getting process. We think it would be extra cool if it stayed down until the recipe popped up. Butter your way past the break to see a short demo video.

We must say, this toaster is way more helpful than the talkie toaster from Red Dwarf.

Handheld 3D Scanning, Using Raspberry Pi 4 And Intel RealSense Camera

Raspberry Pi 4 (with USB 3.0) and Intel RealSense D415 depth sensing camera.

When the Raspberry Pi 4 came out, [Frank Zhao] saw the potential to make a realtime 3D scanner that was completely handheld and self-contained. The device has an Intel RealSense D415 depth-sensing camera as the main sensor, which uses two IR cameras and an RGB camera along with the Raspberry Pi 4. The Pi uses a piece of software called RTAB-Map — intended for robotic applications — to take care of using the data from the camera to map the environment in 3D and localize itself within that 3D space. Everything gets recorded in realtime.

This handheld device can act as a 3D scanner because the data gathered by RTAB-Map consists of a point cloud of an area as well as depth information. When combined with the origin of the sensing unit (i.e. the location of the camera within that area) it can export a point cloud into a mesh and even apply a texture derived from the camera footage. An example is shown below the break.

Rock Out While You Knock Out Germs

We don’t know about you, but we’re pretty tired of singing two rounds of “Happy Birthday” or counting Mississippi to 20 each time we wash our hands. It’s difficult to do it without thinking about the reason why, and that’s not good for positivity. If you’d rather have your spirits lifted every time you hit the sink, you need a better soundtrack.

[Deeplocal] made a soap dispenser that gathers one of your top 20 tunes from Spotify and plays it for 20 seconds while you lather. The best part is that the songs don’t start at 0:00 — the code is written to use the preview clip of each one, so you get the algorithmically-determined best part.

Scrubber is a pretty simple build that uses a Raspberry Pi Zero W and a speaker bonnet powered by a LiPo, but we dig it just the same. The switch is adaptable to pretty much any soap dispenser — just stick two pieces of copper tape where they’ll make contact when the pump is pushed down, and solder wires to them. Check out the demo after the break.

We’ve often wondered how much more water we’re using with all the increased hand-washing out there. Adjusting to this apocalypse is arduous for all of us, but the environment is still a concern, so try to remember to turn the water off while you’re not using it. Is anyone out there working on an easy way to adapt home faucets to add motion or foot control? Because that would be awesome right about now.

The nice thing about Scrubber is that you can focus on washing your hands and doing so properly. If you’d rather watch a digital hourglass to pass the time, light up your lockdown lavatory lifestyle with LEDs.

Launch Console Delivers Enjoyment To Software Deployment

Sometimes it feels as though all the good physical interactions with machines have disappeared. Given our current germ warfare situation, that is probably a good thing. But if fewer than ten people ever will be touching something, it’s probably okay to have a little fun and make your own interfaces for things.

Fun definitely seems to be some of the inspiration behind [sethvoltz]’s retro-style launch console. This two-factor authorization token-based system is responsible for an important task that usually receives no fanfare — deploying code to production.

The console is centered around a Yubikey, which is type of hardware dongle for 2FA. Flipping the guarded toggle switch will initiate the launch sequence, and then it’s time to insert the Yubikey into the 3D-printed lock cylinder and wait for authorization. If the Raspberry Pi decides all systems are go, then the key can be turned ninety degrees and the mushroom button mashed. You have our permission to peek at the declassified demo after the break. Stick around for a CAD view inside the lock cylinder.

Console culture was great, but the old full-size cabinets sure took up a lot of space. If you’re more of a hardware person, check out this mini-console for testing multiple servos.
