Badgelife, The Hardware Demoscene Documentary

August 20, 2018 by Brian Benchoff 19 Comments

Last week, tens of thousands of people headed home from Vegas, fresh out of this year’s DEF CON. This was a great year for DEF CON, especially when it comes to hardware. This was the year independent badges took over, thanks to a small community of people dedicated to creating small-run hardware, puzzles, and PCB art for thousands of conference-goers. This is badgelife, a demoscene of hardware, and this is just the beginning. It’s only going to get bigger from here on out.

We were lucky enough to sit down with a few of the creators behind the badges of this year’s DEF CON and the interviews were fantastic. Right here is a lesson on electronic design, manufacturing, and logistics. If you’ve ever wanted to be an engineer that ships a product instead of a lowly maker that ships a product, this is the greatest classroom in the world.

Hackaday Links: August 19, 2018

August 19, 2018 by Brian Benchoff 20 Comments

If you want to creep everyone out, [Hunter Irving] has your back. He found a weird, creepy knock-off Thomas the Tank Engine toy and mounted a servo to it. This animatronic face is really, really creepy and has the aesthetic of a pastel plastic hell of the forgotten toys destroyed in a day care in 1991. It probably smells like a thrift shop. This rosy-cheeked locomotive shall derail your soul. It sings karaoke.

Like badges? Sure you do. Ph0xx is the badge for the upcoming Fri3d Camp, a family hacker, maker, and DIY camp in Belgium with 600 attendees. The badge features an ESP-32, two 5×7 LED arrays, accelerometer, an 18650 battery with protection and a charger, expansion headers, and this badge is compatible with Lego Technic. Oh yes, they went there.

We’re filing this under ‘but why’. It’s a custom Mercedes-Benz motorcycle, with a sidecar, that looks like an early 80s Benz convertible. [Maarten] stumbled upon a few pics of this, but the google-fu is weak in trying to get some information about this build. Who built it? Why? Does it run?

Here’s something near and dear to my heart: my greatest contribution to humanity so far. The Shitty Add-On spec for this year’s batch of Def Con badges is the reason badges now have their own badges. Now it’s time for a slight upgrade to the standard, and I need your help. The SAO standard 1.1bis will retain the VCC/GND/SDA/SCL layout of the first revision, but to increase mechanical stability and decrease the complexity of populating the headers, we’re adding two pins. Here’s the question: what should these two extra pins do? The current options are adding TX and RX to the standard, or two GPIOs that are undefined, but able to be utilized by each badge team for their own purposes. Those are the two options, but I’m looking for your input in the comments. Hurry up, because we have Superconference badges to build.

You should know the Primitive Technology channel on YouTube. This week he made another step towards the iron age. The basic idea behind this channel is a guy in Australia playing Minecraft in real life, building everything he can, starting with the technology of punching trees. The latest video shows his process for smelting iron. The iron comes from iron-bearing bacterial sludge found in a creek. The geologic disadvantages of northeastern Australia notwithstanding, he’s doing everything else right. He’s making charcoal, and turning that sludge into something that could be a bloom of iron.

Teardown: Queercon 15 Badge (and The Game Hidden Within)

August 11, 2018 by Mike Szczys 15 Comments

Queercon is a conference within a conference. Taking place within DEF CON, Queercon is a social network of LGBT hackers that gathers each year to host events, talks, and a kickin’ pool party. Since 2012 they have also been building electronic badges as part of the fun and I can vouch that they’re contenders for most creative badge design every single year.

A total of 450 electronic badges were made this year, and the aesthetic is as close to a polished consumer product as I have ever seen in a badge, yet they also retain the charm and feel of unique electronics built for hardware geeks. With wireless communication that delivers a complex and clever game to the badges, the designers are encouraging interaction between people (not just between badges). I had the chance to do a teardown of one of these glorious badges, and also gathered quite a bit of info on the puzzles within during Friday’s badge talk in the QC suite.

Join me after the break as I tear down the Queercon 15 hardware badge. If you haven’t yet looked over my review of the official DC26 badge, check that out as well!

First Look At DEF CON 26 Official Badge

August 9, 2018 by Mike Szczys 25 Comments

To the delight of everyone, this year’s official DEF CON badge is an electronic badge chock full of entertainment. Of course there is blinky, the board is artistic, and everyone hopefully maybe gets one (it’s rumored 27,000+ were manufactured) if they don’t run out. But the badge contest at DEF CON is legendary — solve all the puzzles you are awarded the coveted black badge.

The creators of this badge are no strangers to the Hackaday community. Displayed proudly on the board and in the firmware, we discover that The Toymakers are the ones who have put it all on this line this year. Kudos to the dynamic hardware collective from Minnesota. There is no larger pressure cooker in the world of badges than this, and they pulled it off marvelously. Let’s take a look at all the goodies inside.

Most importantly, become a team member of the Hackaday.io DC26 badge solving project page to help discover all that’s involved in this badge. Okay, now let’s dive in!

Programmable Badge Uses E-Ink And ESP8266

August 8, 2018 by Tom Nardi 34 Comments

You’ve probably noticed that the hacker world is somewhat enamored with overly complex electronic event badges. Somewhere along the line, we went from using a piece of laminated paper on a lanyard to custom designed gadgets that pack in enough hardware that they could have passed for PDAs not that long ago. But what if there was a way to combine this love for weighing down one’s neck with silicon jewelry and the old school “Hello my name is…” stickers?

[Squaro Engineering] might have the solution with Badgy, their multi-function e-ink name…well, badge. Compatible with the Arduino SDK, it can serve as anything from a weather display to a remote for your smart home. Oh, and we suppose in an absolute emergency it could be used to avoid having to awkwardly introduce yourself to strangers.

Powered by an ESP-12F, Badgy features a 2.9″ 296×128 E-Ink display and a five-way tactical switch for user input. The default firmware includes support for WiFiManager and OTA updates to make uploading your own binaries as easy as possible, and a number of example Sketches are provided to show you the ropes. Powered by a LIR2450 3.6 V lithium-ion rechargeable coin cell, it can run for up to 35 days in deep sleep or around 5 hours of heavy usage.

Schematics, source code, and a Bill of Materials are all available under the MIT license if you want to try your hand at building your own, and assembled badges are available on Tindie. While it might not be as impressive as a retro computer hanging around your neck, it definitely looks like an interesting platform to hack on.

Unofficial Badges Get Official Recognition At DEF CON: Badge Life Contest

August 3, 2018 by Mike Szczys 3 Comments

Badge·Life (noun): the art of spending too much time, energy, money, and creativity to design and produce amazing custom electronics and get them into the hands of those who appreciate incredible craftsmanship.

Brand new to DEF CON 26 is the Badge Life Contest to celebrate the creativity and ingenuity that gets poured into a custom badge.

For years, #BadgeLife has been flying under the radar at DEF CON. A growing movement of creative designers have put in late nights, emptied pocket books, and agonized over production, shipping, lanyards, boxes, batteries, programming woes, and every other kind of problem you can image to bring hundreds of unofficial badges to the conference. These aren’t a secret, the whole point is to wear blinky badges, often loaded with cryptographic puzzles and wireless interactivity, around your neck. For many, acquiring an awesome badge is a must-do to make their con a successful one. But DEF CON hasn’t officially recognized BadgeLife, until now.

If you’re a badge creator, you should show off your badge as part of the contest. It’s an opportunity to let more people see all the details that make each badge a work of art. During the con, most people will only see badges as they walk past them in the hallway. For the contest, all badges will be on display in the Hardware Hacking Village during the weekend to provide a close look for everyone.

The judging panel for this is an incredible slate of talented and well-known people from the hardware community. It doesn’t look like those names have been made public yet, but I’m honored and humbled to be among them. Help kick this inaugural year of the Badge Life Contest off right. You can submit your badge information now and deliver one badge (which will be returned to you) for display by 5 pm PDT on Friday 8/10.

Video Review: AND!XOR DEF CON 26 Badge

July 30, 2018 by Mike Szczys 9 Comments

The AND!XOR team have somehow managed to outdo themselves once again this year. Their newest unofficial hardware badge for DEF CON 26 just arrived. It’s a delightful creation in hardware, software, and the interactive challenges built into both.

They call this the “Wild West of IoT”, a name that draws from the aesthetic as well as the badge-to-badge communications features. Built on the ESP32-WROVER module which brings both WiFi and Bluetooth to the party, the badges are designed to form a wireless botnet at the conference. Anyone with a badge can work to advance their level and take more and more control of the botnet as they do.

Check out the video overview and then join me below for a deeper dive into all this badge has to offer.
