Video Review: AND!XOR DEF CON 26 Badge

July 30, 2018 by 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.

IHC Badge: It’s Not (Quite) A Nokia

July 22, 2018 by 16 Comments

Electronic conference badges are an integral part of our culture, and have featured many times here. The norm for a badge is an exquisitely designed printed circuit board with some kind of microcontroller circuit on it, often a display, and some LEDs.

This is not enough though for [Mastro Gippo], for he has given us an interesting alternative, the shell of a Nokia 3310 mobile phone fitted with a new motherboard holding an ESP32 module, and of course that classic display. It is to be the badge for IHC Camp, which initialism if you hadn’t guessed stands for Italian Hacker Camp, and which will run from the 2nd to the 5th of August 2018 in Padova, Italy. It’s worth reminding readers, at the time of writing IHC tickets are still available, so get ’em while they’re hot!

The board itself is a beautiful piece of work, and aside from the Nokia’s keyboard and display it holds the ESP module and an STM32F103 microcontroller that handles all the peripherals. There is no microphone, after all this is a badge rather than a phone, but there is space for a LoRa module. He’s done another fascinating post about the PCB design, including the on-board wireless antenna.

We have seen a lot about badges from the #BadgeLife scene surrounding the USA’s DEFCON courtesy of our colleague [Brian Benchoff], so it is particularly interesting to see badges from the opposite side of the Atlantic. This is an artform whose journey still has a way to go, and we’ll be along for the ride!

Belgrade Badge Hacks

July 20, 2018 by 6 Comments

We’re still coming off the Hackaday Belgrade conference right now. If you were there, you know it was the greatest hardware conference ever. If you weren’t there, you missed out. Sorry. (Make sure you get in on the Hackaday Superconference in November.)

One of the many highlights of the Belgrade conference was, of course, the badge. The 2018 Hackaday Belgrade Badge is a masterpiece of hardware with a 55-key keyboard, RGB TFT LED, speaker, and a BASIC interpreter.

This badge is a masterpiece of electronic design by Voja Antonic. Just to take one small example from the design, check out the placement of the buttons. Think the slightly rotated buttons that make up the keyboard is only a stylistic choice? It’s not; by carefully rotating each button, the legs of each switch can fit in between each other. It’s brilliant.

Starting hardware this good, adding amazing software by Jaromir Sukuba to bring it to life, and distributing a badge to each hacker through the door is the perfect recipe for some amazing hacks. What were the best badge hacking tricks we saw at the 2018 Hackaday Belgrade conference? Check out the video of the badge hacking ceremonies and then join us below for a few of our favorites.

Using Pad Printers To Add Color To Artistic PCBs

July 19, 2018 by 11 Comments

I’ve done a few experiments in adding color to printed circuit boards. These experiments used a process known as pad printing, and so far all indications are that pad printing is a viable process for truly multicolor artistic PCBs. For this year’s DEF CON, I’m stepping things up and taking them to their logical conclusion. I’m making true multicolor PCBs with orange and blue ink. This is, I believe, the first time this has ever been done with printed circuit board art, and it is certainly the first time it has ever been documented.

You may be wondering why I need more color on my boards. It’s that time of year again where PCB artisans all around the world are gearing up for badgecon DEF CON. For the last few years, independent badge makers have come together to form a demoscene of hardware creation. This year, add-ons for badges are a thing, and everyone is getting in on the game. Tindie is filled with amazing electronic badges and add-ons that will be found at this year’s DEF CON. There are badges featuring the Cromulon from Rick and Morty, baby Benders from Futurama, pikachus, and glowing tacos.

This is all about badge art, but when it comes to rendering an image in fiberglass and soldermask, everyone is working with a limited palette. Yes, you can get pink and orange soldermask, but I can’t find a place that will do it inexpensively. For any PCB, your choice of colors are only green, red, yellow, blue, purple, black, or white. No, you can’t mix them.

But I want both orange and blue, on the same board, cheaply and easily — here’s how I did it.

A Sneak Preview Of The Hacker Warehouse Badge

July 6, 2018 by 5 Comments

We were lucky enough to get our hands on a hand-soldered prototype of the new Hacker Warehouse badge, and boy is this one a treat. It’s fashionable, it’s blinky, and most impressively, it’s a very useful tool. This badge can replace the Google Authenticator two factor authentication app on your phone, and it’s a USB Rubber Ducky. It’s also a badge. Is this the year badges become useful? Check out the video below to find out more.

This is the time of year when hardware hackers from all across North America are busy working on the demoscene of hardware and manufacturing. This is badgelife, the celebration of manufacturing custom wearable electronics for one special weekend in Las Vegas. In just about a month from now, there will be thousands of independent badges flooding Caesar’s Palace in Vegas, complete with blinkies, custom chips, innovative manufacturing processes, and so many memes rendered in fiberglass and soldermask.

This Year, Badges Get Blockchains

June 28, 2018 by 11 Comments

This year’s hottest new advance in electronics comes through wearable badges. You can’t have failed to notice another technology that’s getting really hot. It’s the blockchain. What is a blockchain? It’s a linked list where every item in the list contains a cryptographic hash of the previous item in the list. What is a blockchain in English? It’s the most revolutionary technology that’s going to solve every problem on the planet, somehow. It’s the basis for crypto (no not that one, the other one). The blockchain is how you add more Lamborghinis to your Lamborghini account. Even though we’re still trying to figure out how it solves a single problem, one thing is certain: blockchains solve every problem. We were born too late to explore the Earth, born too early to explore the Universe, but just in time for blockchain.

Independent badges are always looking at the latest technology, and perhaps this was inevitable. It’s a badge built on the blockchain. It’s a wearable sneakernet of mining. It’s a game with collaborative proof of work.

The blockchain badge from [Mr Blinky Bling] is an independent badge for this year’s Defcon, and like most independent badges it’s loaded up with RGB LEDs, microcontrollers, and exquisitely crafted FR4. What makes this badge different is the add-ons, or ‘blocks’ that attach to the main badge through 1/8″ phono jacks. These blocks form the basis of the social game, where two badge holders trade blocks for a while, allow their badges to perform a proof of work on each block, and finally, each block is hashed and the score increased. Yes, this is a blockchain, but it’s more of a block-tree, and it runs on sneakernet instead of the Internet.

Yes, this does indeed all sound like a joke. Make no mistake, though: this is real. This is a hardware game built on blockchain technology, that some lucky badge holders will be playing at this year’s Defcon. It’s filled with blinky and blockchain. It’s awesome.

[Mr. Blinky Bling] has already started a project for this badge over on hackaday.io, and right now they’re running a Kickstarter campaign for this badge with delivery at Defcon. This is one of the more interesting badges that will be floating around the con this year, and it has blockchain. This really isn’t one to miss.

This Is The Year Conference Badges Get Their Own Badges

June 21, 2018 by 17 Comments

Over the last few years, the art and artistry of printed circuit boards has moved from business cards to the most desirable of all disposable electronics. I speak, of course, of badgelife. This is the community built on creating and distributing independent electronic conference badges at the various tech and security conferences around the globe.

Until now, badgelife has been a loose confederation of badgemakers and distributors outdoing themselves each year with ever more impressive boards, techniques, and always more blinky bling. The field is advancing so fast there is no comparison to what was being done in years past; where a simple PCB and blinking LED would have sufficed a decade ago, now we have customized microcontrollers direct from the factory, fancy new chips, and the greatest art you’ve ever seen.

Now we have reached a threshold. The badgelife community has gotten so big, the badges are getting their own badges. This is the year of the badge add-on. We’re all building tiny trinkets for our badges, and this time, they’ll all work together. We’re exactly one year away from a sweet Voltron robot made of badges.
