Hackaday Podcast 233: Chandrayaan On The Moon, Cyberdecks, Hackerspaces Born At A German Computer Camp

August 25, 2023 by Kristina Panos 5 Comments

This week, Editor-in-Chief Elliot Williams and Kristina Panos experimented with the old adage that brevity is the soul of wit. That’s right; this week, they’re all Quick Hacks, and that’s to make room for a special series of interviews that Elliot recorded at CCCamp with the pillars of US hackerspace creation. This one’s really special, do have a listen.

We still made room for the news this week: India launched Chandrayaan-3, which combines an orbiter, lander, and rover all in one. Then it’s on to the What’s That Sound results show, and while Kristina did not get it right, she did correctly identify it as being used in Whitney Houston’s “I Wanna Dance With Somebody”, as did one of the guessers who identified it as the cowbell sound from a Roland 808.

Then it’s on to the (quick) hacks, where we alternated for once just to keep things interesting. This week, Elliot is into 3D printing a clay extruder and then printing pottery with that, z-direction conductive tape, and the humble dipole antenna. Kristina is more into cyberdecks for the young and old, a reusable plant monitor, and 3D printing some cool coasters.

2023 Cyberdeck Challenge: CyberTapeDeck

August 23, 2023 by Tom Nardi 9 Comments

There seem to be two schools of thought when it comes to picking an enclosure for your cyberdeck project: you either repurpose the carcass of some commercially produced gadget, or you build a new case yourself. The former can lead to some very impressive results, especially if your donor device is suitably vintage, but the latter is far more flexible as the design will be based on your specific parameters.

But for the CyberTapeDeck, [Matthew] decided to take a hybrid approach. The final product certainly looks like it’s built into a 1980s portable tape deck, but on closer inspection, you’ll note that the whole thing is actually 3D printed. The replica doesn’t just nail the aesthetics — it also includes the features you’d expect from the real thing, including an extendable handle and functional buttons which the internal Raspberry Pi 3 sees as a macropad thanks to an Arduino Pro Micro.

A seven inch LCD stands in for the tape door, and while it unfortunately doesn’t look like [Matthew] was able to replicate the opening mechanism to angle the display, you can at least stand the whole thing on its end to provide a more comfortable viewing experience.

[Matthew] says one of the intended purposes for this cyberdeck is to get his son excited about working with electronics and programming, so in a particularly nice touch, he’s mounted a terminal block over the “speaker” that ties into the Pi’s GPIO pins. This provides a convenient interface for experimenting on the go, without getting tangled up in exposed wiring.

We appreciate that [Matthew] has released the STL files for all of the printed parts, because even though it makes a great cyberdeck, the design is begging to house a faux-retro media player.

2023 Cyberdeck Challenge: Modular Cyberdeck Creation Kit

August 22, 2023 by Brian McEvoy 3 Comments

We were fortunate to run into [Sp4m] at DEFCON31 and see his Modular Cyberdeck Creation Kit in person. In fact, he was wearing it around the hallways like a rogue decker in search of fellow runners. Holding the unit feels like a serious tool because of its weight, mainly from the battery. Everything hangs from a single-point sling on a metal handle, probably from the cabinetry aisle, and we could move silently and comfortably. The sling is firearm-rated, which is appropriate since he has a printed Weaver rail on top. It just needs a flashlight/laser combo.

[Sp4m] aims to create printable parts that combine any on-hand materials into a usable cyberdeck. In this iteration, he uses a wired Apple keyboard and trackpad he found in the trash, so we have to assume he works in IT. Most of the trackpad is covered, but enough is accessible to scroll and maneuver the mouse, saving almost six inches. The Steam deck is the current head but is removable so that this hardware collection can work for many USB-C tablets without fuss.

The eye-catching white/orange is no accident and may earn it a top spot in the Icebreaker category of the 2023 Cyberdeck Contest. The judges are currently deliberating, so keep an eye out for an announcement about the winners shortly.

2023 Cyberdeck Contest: A Toddler’s Cyberdeck

August 17, 2023 by Dave Rowntree 5 Comments

[Josh] has a child and what do children like more than stuffing random things into their mouths? Pushing buttons, twiddling knobs, and yanking things of course! So [Josh] did what any self-respecting hacker would do and built his little man a custom cyberdeck.

The build follows the usual route of some electronics wedged into a pelican-style waterproof case — which is a good choice for this particular owner — a repurposed all-in-one LCD video player in the lid and a bunch of switches in the base. The player is apparently a V100-base SBC the likes of which are used in shops for those annoying looping promotional videos, but it doesn’t really matter if all it’s doing is being a focus point.

There is no connection from the base to the ‘display’ but that doesn’t matter here. The base is the fun part, with lots of old-school toggle switches and rotary knobs to play with and a load of LEDs to flash in mysterious ways. The guts of this are controlled via an Arduino Mega 2560, with copious amounts of hot glue on display in true hacker style. On the coding side of things, [Josh] used ChatGPT to produce the code from his prompting and Wokwi to simulate it before deployment to the hardware.

2023 Cyberdeck Contest: Cyberdeck Red Is Ready For Action

August 17, 2023 by Dan Maloney 8 Comments

What exactly constitutes a cyberdeck is up for debate, but for us, one thing is clear: A cyberdeck needs to look like it’s ready to go to battle. When the machines finally rise up and try to wipe us all out, someone toting around a machine like Cyberdeck Red is probably going to be a sight for sore eyes; clearly, such a person would be equipped to help us fight back the robotic scourge.

If this cyberdeck looks familiar, it’s for a good reason — it’s [Gabriel]’s second stab at this build. We thought the original was pretty keen, enough so that it won second prize in the 2022 contest. But like many cyberdeck builders, good enough isn’t good enough, and so rather than rest on his laurels, he set about improving a few things. The most visible of the changes are the spiffy new case, which is far less utilitarian than version one, and the new custom-made split keyboard. Things are a little different under the hood too; gone is the Raspberry Pi 4, which was replaced by Latte Panda 3 Delta running Windows. And like the original, version two is absolutely stuffed with sensors and diagnostic gear — a Hack RF SDR for radio work, plus an Analog Discovery 2 which provides everything from an oscilloscope and signal generator to a spectrum analyzer and an impedance tester.

But possibly the most useful feature of Cyberdeck Red is the onboard HDMI projector. The palm-sized, short-throw projector would be perfect for an impromptu combat briefing in an improvised command post, or just watching Netflix. If the machines will allow it, of course.

The 2023 Cyberdeck Contest wraps up August 15, so it looks like [Gabriel] just squeaked this one in on time. We wish him and all the other entrants the best of luck!

2023 Cyberdeck Challenge: A Ham Radio Cyberdeck

August 15, 2023 by Lewin Day 27 Comments

Cyberdecks rock because their homebrewed nature lets them feature all kinds of nifty additional functionality. [Kaushlesh] has built his deck with an eye to ham radio use, and it’s a rugged and impressive thing.

The deck is built into a weatherproof enclosure, with various 3D-printed parts helping to integrate the components into the clamshell enclosure. It runs on a Raspberry Pi 4, with [Kaushlesh] springing for the hefty model with 8GB of RAM. It has a 10-inch LCD screen and a rechargable battery pack with an impressive 20 hour battery life, and is intended for use when [Kaushlesh] is out camping or participating in ham radio field days. To that end, it’s equipped with a USB software-defined radio module and a BNC connector for hooking up an external antenna. It also has a game controller that mounts inside, just in case he desires playing a few games on Retropie while he’s out and about. It’s even got storage for a mouse and rocks a decent-sized keyboard inside.

We’d love to tote this to a hamfest for a bit of hacking on the side. It’s not the first ham-themed cyberdeck we’ve seen, either. Now we just need one built for prosciutto. Video after the break.

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.
