Hands-On: Internet Of Batteries Quantum Badge Brings Badgelife Add-Ons The Power And Internet They Crave

August 9, 2020 by 13 Comments

Our friends in the Whiskey Pirates crew sent me the unofficial DEF CON badge they built this year. The Internet of Batteries QUANTUM provides power and connectivity to the all-important add-on badges of DC28. The front of the badge is absolutely gorgeous to the point I don’t really want to solder on my add-on headers and disrupt that aesthetic.

The gold-plated copper makes for a uniformed and reflective contrast to the red solder mask which occupies the majority of the front. Here we see the great attention to detail that [TrueControl] includes in his badges. The white stripe of silk screen separating the two colors is covered by some black detailing tape that looks much better than the white.

The antenna of the ESP32 module poking out the underside of the gold cover end of the badge gets its own rectangle of the holographic sticker material, the same as the sheet of stickers that was included in the box. Both decals are small details that make a huge difference to your eye.

The line of nine RGB LEDs have black bezels which goes along with the black stripe motif and underscores the typography of the badge name. These lights are hosted on a daughter board soldered to the underside of the badge with a slot for the LEDs to pass through. They are addressed in a 2×15 matrix that is scanned on the low side by the PSoC5 that drives the badge. This low-res image shows that daughter board before the lithium cell is placed.

Hands-On: AND!XOR Unofficial DC28 Badge Embraces The Acrylic Stackup

August 7, 2020 by 1 Comment

Still hot from the solder party, a new AND!XOR badge just landed on my desk courtesy of the hacking crew that has been living the #badgelife for the past five years. Originally based on the Futurama character Bender, the design has morphed to the point that it’s no longer recognizable as a descendant of that belligerent robot. Instead we have a skeletal midget whose face is half covered by a gear-themed mask.

CampZone 2020 Badge Literally Speaks To Us

July 31, 2020 by 5 Comments

The pandemic has left my usual calendar of events in shambles this year. Where I’d have expected to have spent a significant portion of my summer mingling with our wonderful and diverse community worldwide, instead I’m sitting at home cracking open a solitary Club-Mate and listening to muffled techno music while trying to imagine myself in a field somewhere alongside several thousand hackers.

As a knock-on effect of the event cancellations there’s another thing missing this summer, the explosion of creativity in the world of electronic conference badges has faltered. Badges are thin on the ground this year, so the few that have made it to production are to be treasured as reminders that life goes on and there will be another golden summer of hacker camps in the future. This year, the CampZone 2020 badge was given its own voice and perform neat tricks like presenting a programming interface via WebUSB!

The Hacker Hotel 2020 Badge

March 12, 2020 by 1 Comment

The art of the electronic conference badge has evolved over the last decade or more, such that for an individual example to be of note it now has to include some exceptional features. Perhaps a function that might previously have been considered impossible in a badge, or maybe an unusually beautiful design, an entertaining and compelling functionality, or it simply pushes the capabilities of an otherwise limited device in an unusually ingenious way. The badge from the recent Hacker Hotel 2020 comes from the same badge team that created the software platform derived from the SHA 2017 badge, and it ticks many of these boxes by combining a genuine work of art with a set of delightfully intricate puzzles at enough levels to interest all participants in the event.

Watch Linux Boot On Your Hackaday Superconference Badge

February 29, 2020 by 4 Comments

Last year’s Hackaday Superconference badge was an electronic tour de force, packing an ECP5 FPGA shoehorned into a Game Boy-like form factor and shipping with a RISC-V core installed that together gave an almost infinite badge hacking potential. It did not however run Linux, and that’s something [Greg Davill] has addressed, as he’s not only running Linux on his badge, but also a framebuffer that allows him to use the badge screen as the Linux terminal screen. Finally you can watch Linux boot on your Superconference badge itself, rather than over its serial port.

He’s achieved this by changing essentially everything: from the new VexRiscv CPU core, to new video drivers and a VGA terminal courtesy of Frank Buss, now part of the LiteVideo project. It’s not quite a fully fledged Linux powerhouse yet, but you can find it in a GitHub repository should you have a mind to try it yourself. Paging back through his Twitter feed reveals the effort he’s put into this work over the last few months, and shows that it’s been no easy task.

For those keeping score at home, this is an open hardware design, running an open CPU core, with community-designed open-source peripherals, compiled by an open-source toolchain, running an open-source operating system. And it’s simply a fantastic demo for the badge, showing off how flexible the entire system is. One of the best parts of writing for Hackaday is that our community is capable of a huge breadth of amazing pieces of work, and this is an exemplar of that energy. We can’t wait to see what Greg and any other readers tempted to try it will come up with.

If you’d like to refresh your memory over the 2019 Supercon badge, here’s our write-up at the time.

Developing Retro Games For Conference Badges With Kate Morris

February 26, 2020 by No comments

PCB badges have exploded in popularity in recent years. Starting out as a fun token of entry to a conference, they’re now being developed by all manner of independent groups, with DEFCON serving as the heart of the #badgelife movement. After DEFCON 26, Kate Morris and associates decided to undertake the development of their own badge, to celebrate the 50th anniversary of the Apollo landing. Kate’s talk at the 2019 Hackaday Superconference serves to tell the tale of creating a retro game to run on a badge platform.

The CarolinaCon 16 Badge Slithers Into Life

February 19, 2020 by 2 Comments

It’s something of an unwritten rule at this point that you can’t hold a hacking conference without providing a badge with at least a few LEDs on it. Not only can they be a great way to learn electronics for the attendees that tinker with them, but they’re a keepsake to commemorate the event. As a perfect example, [Matt Agius] recently wrote in to tell us about the badge he’s made for the upcoming CarolinaCon 16.

As [Matt] explains, the idea with this badge was to make it as easy as possible for attendees to assemble. In the final version there are only going to be three components that need to be soldered, so even if they’ve never touched SMD components before, they should still be able to get their badge lit up.

The badge largely makes up for its simplistic electronics with some fantastic board art on the flip side. The two red LEDs illuminate the eyes of a rather sinister looking octopus that’s ensnaring the unsuspecting state of North Carolina in its tentacled grip. The art was originally done by [Katie Dorn], with [Matt] spearheading its conversion into something that could be sent out for PCB fabrication.

Anyone looking to add this latest entry to their growing collection of badges will need to attend CarolinaCon on April 10th and 11th, where you’ll be able to catch a talk [Matt] is giving on the subject called “How to design Printed Circuit Boards for Hacking and for Art”.
