2022 Cyberdeck Contest: Cyberpack VR

Feeling confined by the “traditional” cyberdeck form factor, [adam] decided to build something a little bigger with his Cyberpack VR. If you’ve ever dreamed of being a WiFi-equipped porcupine, then this is the cyberdeck you’ve been waiting for.

Craving the upgradability and utility of a desktop in a more portable format, [adam] took an old commuter backpack and squeezed in a Windows 11 PC, Raspberry Pi, multiple wifi networks, an ergonomic keyboard, a Quest VR headset, and enough antennas to attract the attention of the FCC. The abundance of network hardware is due to [adam]’s “new interest: a deeper understanding of wifi, and control of my own home network even if my teenage kids become hackers.”

The Quest is setup to run multiple virtual displays via Immersed, and you can relax on the couch while leaving the bag on the floor nearby with the extra long umbilical. One of the neat details of this build is repurposing the bag’s external helmet mount to attach the terminal unit when not in use. Other details we love are the toggle switches and really integrated look of the antenna connectors and USB ports. The way these elements are integrated into the bag makes it feel borderline organic – all the better for your cyborg chic.

For more WiFi backpacking goodness you may be interested in the Pwnton Pack. We’ve also covered other non-traditional cyberdecks including the Steampunk Cyberdeck and the Galdeano. If you have your own cyberdeck, you have until September 30th to submit it to our 2022 Cyberdeck Contest!

Giving Environmental Readouts Some Personality

Air Quality Index for one’s region can be a handy thing to know, but it’s such a dry and humorless number, isn’t it? Well, all that changes with [Andrew Kleindolph]’s AQI Funnies: a visual representation of live AQI data presented by a friendly ghost character in a comic panel presentation. The background, mood, and messaging are all generated to match the current conditions, providing some variety (and random adjectives) to spruce things up.

We love the attention paid to the super clean presentation, and the e-paper screen looks fantastic. Inside the unit is a Raspberry Pi using Python to talk to the AirNow.gov API to get local conditions and update every four hours (AirNow also has a number of useful-looking widgets, for those interested.)

The enclosure is 3D printed, and [Andrew] uses a Witty Pi for power management and battery conservation. The display is a color e-paper display that not only looks great, but has the advantage of not needing power unless the display is updating. The Pi can be woken up to update the screen with new info when needed, but otherwise can spend its time asleep.

[Andrew] has a knack for friendly presentations of information with an underlying seriousness, as we saw with his friendly reminders about nasty product recalls.

Pi Pico W Does PCMCIA, Gets This IBM PC110 Online

Bringing modern connectivity to retro computers is an endearing field- with the simplicity of last-century hardware and software being a double-edged sword, often, you bring a powerful and tiny computer of modern age to help its great-grandparent interface with networks of today. [yyzkevin] shows us a PCMCIA WiFi card built using a Pi Pico W, talking PCI ISA. This card brings modern-day WiFi connectivity to his IBM PC110, without requiring a separate router set up for outdated standards that the typical PCMCIA WiFi cards are limited by.

The RP2040 is made to talk PCI ISA using, of course, the PIO engine. A CPLD helps with PCI ISA address decoding, some multiplexing, and level shifting between RP2040’s 3.3V and the PCI 5 V levels. The RP2040 software emulates a NE2000 network card, which means driver support is guaranteed on most OSes of old times, and the software integration seems seamless. The card already works for getting the PC110 online, and [yyzkevin] says he’d like to improve on it – shrink the design so that it resembles a typical PCMCIA WiFi card, tie some useful function into the Pico’s USB port, and perhaps integrate his PCMCIA SoundBlaster project into the whole package while at it.

This is a delightful project in how it achieves its goal, and a pleasant surprise for everyone who’s been observing RP2040’s PIO engine conquer interfaces typically unreachable for run-of-the-mill microcontrollers. We’ve seen Ethernet, CAN and DVI, along many others, and there’s undoubtedly more to come.

We thank [Misel] and [Arti] for sharing this with us!

Big 3D Printed BMO Is Also An OctoPrint Server

OctoPrint is a useful tool for 3D printers, providing remote access to essentially every 3D printer with a USB port. [Allie Katz] decided to build an OctoPrint server in the shape of a life-sized BMO from Adventure Time, and the results are cute as heck.

A Raspberry Pi 4 is the heart of the build, with [Allie] selecting a 8 GB model for the job. It’s paired with a Raspberry Pi touchscreen that serves as BMO’s face. The Pi is also given a stereo audio output board, and hooked up to a custom PCB that runs all of BMO’s buttons. Printing BMO itself was fairly straightforward, but requires some experience working with larger PETG parts. A useful note for those playing along at home is that Polymaker PolyLite PETG in teal is just about a perfect dupe for BMO’s authentic body color.

A bit of Python code animates BMO’s face and delivers funny quips at the press of a button. When it’s time to work, though, the touchscreen serves as a straightforward interface for OctoPrint. The resulting build is both fun and functional, and a great example of what 3D printing really can achieve. It’s a cute figurine and a functional print all in one, something we don’t see everyday!

Simple Internet Radio Transplant

While we have a definite sweet spot in our hearts for analog radio, there are times that just call for a digital upgrade. One of the downsides that can come with this upgrade is complexity. For example, the more software-minded among us might base their build on the Music Player Daemon, and use a web interface for control. But that’s not everyone’s idea of a good time, and particularly an older user of your gizmos might really appreciate a simple, tactile user interface. That’s the situation [Blake Hannaford] was in, while building an Internet powered radio for someone else.

The solution was to take a familiar analog radio, the Tivoli Audio Model One, and give it a digital makeover. Now before you get worked up about wrecking the purity of a classic radio, note that the Model One is a faux-classic, made in 2000. No antiques were harmed in the making of this hack, and the exterior is essentially left stock — the only visible modification being the taped-on tuner label.

Inside it’s a Raspberry Pi Zero, the Adafruit Audio Bonnet, and a 3D printed bracket to tie a variable potentiometer to the tuning knob. The original volume knob and speaker are re-used. As [Blake] says, sometimes all you need is tuning and volume. Plus, re-using the speaker means that the whole unit still sounds great. Sometimes simple really is best.

It’s Pi All The Way Down With This Pi-Powered Pi-Picking Robot

While most of us live in a world where the once ubiquitous Raspberry Pi is now as rare as hens’ teeth, there’s a magical place where they’ve got so many Pis that they needed to build a robotic dispenser to pick Pi orders. And to add insult to injury, they even built this magical machine using a Raspberry Pi. The horror.

This magical place? Australia, of course. There’s no date posted on the Pi Australia article linked above, but it does mention that there’s a Pi 4 Model B running the show, so that makes it at least recent-ish. Stock is stored in an array of tilted bins that a shuttle mechanism accesses via an X-Y gantry. The shuttle docks in front of a bin and uses a stepper-controlled finger to flip a box over the lip holding them in its bin. Once in the shuttle, the order is transported to an array of output bins, where a servo operates a flap to unceremoniously dump the product out for packing and shipping. There’s a video of a full cycle below, but a word of warning — the stepper motors on the X-Y gantry really scream, so you might want to lower the volume.

The article goes into more detail on not only the construction of “Bishop” — named after the heroic synthetic organism from Aliens — but also the challenges faced during construction. It turns out that even when you try to use gravity to simplify a system like this, things can go awry very easily. There’s also a fair bit of detail on the software, which surprisingly centers around LinuxCNC. And there are plans to take this further, with another bot to do the packing, sealing, and labeling of the order. If they need all that automation down there, we guess we found all the missing Pis.

Raspberry Pi Grants Remote Access Via PCIe (Sort Of)

[Jeff] found a Raspberry Pi — well, the compute module version, anyway — in an odd place: on a PCI Express card. Why would you plug a Raspberry Pi into a PC? Well, you aren’t exactly. The card uses the PCI Express connector as a way to mount in the computer and connect to the PC’s ground. The Pi exposes its own network cable and is powered by PoE or a USB C cable. So what does it do? It offers remote keyboard, video, and mouse (KVM) services. The trick is you can then get to the PC remotely even if you need to access, say, the BIOS setup screen or troubleshoot an OS that won’t boot.

This isn’t a new idea. In fact, we’ve seen the underlying Pi-KVM software before, so if you don’t mind figuring out your mounting options for a Raspberry Pi, you probably don’t need this board. Good thing too. Judging by the comments, they are hard to actually buy — perhaps, due to the chip shortage.
