Hello, Halloween Hackfest!

September 19, 2023 by Elliot Williams 1 Comment

Halloween is possibly the hackiest of holidays. Think about it: when else do you get to add animatronic eyes to everyday objects, or break out the CNC machine to cut into squashes? Labor day? Nope. Proximity-sensing jump-scare devices for Christmas? We think not. But for Halloween, you can let your imagination run wild!

We’re happy to announce that DigiKey and Arduino have teamed up for this year’s Hackaday Halloween Contest. Bring us your best costume, your scariest spook, your insane home decorations, your wildest pumpkin, or your most kid-pleasing feat!

We’ll be rewarding the top three with a $150 gift certificate courtesy of DigiKey, plus some Arduino Halloween treats if you use a product from the Arduino Pro line to make your hair-raising fantasy happen.

We’ve also got five honorable mention categories to inspire you to further feats of fancy.

Costume: Halloween is primarily about getting into outrageous costumes and scoring candy. We don’t want to see the candy.
Pumpkin: Pumpkin carving could be as simple as taking a knife to a gourd, but that’s not what we’re after. Show us the most insane carving method, or the pumpkin so loaded with electronics that it makes Akihabara look empty in comparison.
Kid-Pleaser: Because a costume that makes a kid smile is what Halloween is really all about. But games or elaborate candy dispensers, or anything else that helps the little ones have a good time is fair game here.
Hallowed Home: Do people come to your neighborhood just to see your haunted house? Do you spend more on light effects than on licorice? Then show us your masterpiece!
Spooky: If your halloween build is simply scary, it belongs here.

Head on over to Hackaday.io for the full details. And get working on your haunts, costumes, and Rube Goldberg treat dispensers today.

2023 Cyberdeck Challenge: The Best Decks On The Net

September 7, 2023 by Tom Nardi 2 Comments

It was an easy decision to run a Cyberdeck Challenge in 2023 — after all, it was far and away one of our most popular contests from last year. But what was much harder was sorting out the incredible array of bespoke computers that readers have been sending in for the last few months.

Our judges have painstakingly whittled down the list of entries to get our top three winners, each of which will be awarded $150 in credit from the good folks over at DigiKey. But there were simply too many fantastic custom computers in the running to let everyone else go home empty-handed, so we’ve decided to also break out some $50 Tindie gift cards for the decks that best exemplified this year’s special categories.

Without further ado, let’s take a tour through the judge’s top picks for this year’s Cyberdeck Challenge!

Hackaday Prize 2023: The Gearing Up Challenge Finalists

September 5, 2023 by Dan Maloney 3 Comments

If there’s more to life than just a workshop full of tools, it’s probably a workshop full of tools that you’ve built yourself. At least that was the thinking behind the recently concluded “Gearing Up” challenge of the 2023 Hackaday Prize, which unsurprisingly generated quite a list of entries for our judges to review and whittle down to their top ten favorite tools, jigs, fixtures, and general labor-savers.

Having piqued the interest of our crack team of judges, these ten projects have not only earned a spot in the 2023 Hackaday Prize Finals, but they’ll also get a $500 cash prize to boot. But the heat is really on now; like all the finalists from the previous rounds, they’ve only got until October to get their projects as far along as they can before the final round. The grand prize is grand indeed — $50,000 in cash and a residency at the Supplyframe Design Lab in Pasadena!

We’re really getting down to the wire here, but it’s worth taking a little time out to look at some of the Gearing Up challenge winners, and what they came up with to make life in the shop a little easier. And don’t forget — the one who dies with the most tools wins!

2023 Cyberdeck Challenge: KOAT0 Portable Terminal

August 26, 2023 by Jenny List 16 Comments

We’ve had cyberdecks as part of the scenery for long enough now that there are a series of common elements that appear across many different builds. The Raspberry Pi, for instance, or the mechanical keyboard, with a 3D printed body. [RobsonCuto]’s KOAT0 Portable Terminal has some of those in a particularly slim and neat design. The orange and grey color scheme is great really pops. Where this deck really shines though, is the display. He’s eschewed LCDs or OLEDs, even CRTs, and gone for an unusual choice in a dot-matrix VFD.

The VFD in question is commonly available on AliExpress where it appears to be used for displaying Chinese characters. It’s not an obvious choice for a cyberdeck, so once the tidy-looking case is complete the real challenge in this project becomes how to drive it from the Pi. To that end, he appears to have some kind of text output working but still needs to complete a framebuffer driver. We applaud the effort and we really like the display. We’re curious as to how its meager resolution might best be used in a Linux device.

All in all, this is a ‘deck we’d be happy to use ourselves if it were an option. We particularly like the on-the-arm style of use, and we’re pretty sure it’s the first time we’ve seen one of these displays on these pages.

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.
