When the second band had played its last encore, before the legendary DJ took the stage, a cadre of hardware hackers climbed three steps with a twinkle in their eyes and glowing electronics in their hands. I’m surprised and relieved that the nugget of excitement that first led me to twiddle a byte in a microcontroller is still alive, and this moment — this crossroads of hacker family — stirred that molten hot center of adventure in everyone.
The badge hacking demoscene is a welcoming one. No blinking pixel is too simple, and no half-implemented idea falls short of impressing everyone because they prove the creativity, effort, and courage of each who got up to share their creation. How could we ever get together as a community and not do this?
It was after midnight before we began the demoparty. I somehow managed to come to the Hackaday | Belgrade conference without a USB webcam to use as a top-down camera. I also didn’t line up someone to record with a camera until minutes before. Please forgive our technical difficulties — we first tried to use a laptop webcam to project to the bigscreen. When that failed, focusing on the badges because tough for our ad-hoc camera operator. This video is a hack, but I think it’s worth looking past its tech problems.
The crowd gathered as close to the stage as possible and there was electricity in the audience as the wiles of the day were explained. Join me after the break for a brief rundown of each demo, along with a timestamp to find it in the video.

We have an amazing line-up of talks for Hackaday | Belgrade, Saturday April 9, in Belgrade, Serbia. The talks have been sold out for weeks. You can still get a ticket to the night’s concerts if you’re in the area. Either way, the big news this morning is that we will stream all of the talks live!
Live-stream links will be posted on the conference page as soon as we get them. You should also join the chat over on the Hackaday | Belgrade project page. Just click the “request to join this project” button in the upper right. Do that right now.
There are a ton of great speakers, check the poster below. I’m excited to hear Mike Harrison (mikeselectricstuff) speak about his journey down the rabbit hole of video projection tech, Phoenix Perry’s talk on Forward Futures, Voja Anotic’s talk about the hardware badge, Peter Philip’s talk about reinventing VHDL, and pretty much all of the rest too! From the Hackaday crew you can watch Sophi Kravitz give a talk on her shutter glass project, Chris Gammell will be talking Top Down Electronics, and I will end the 8-versus-32 argument once and for all (yeah right!).
While you’re listening to the talks, why not try your hand at badge hacking. You don’t need any hardware, you can use the emulator to try out your hacked code right now your own computer. We’ll be sending out prizes for the best entries and there are only a handful so far.
You do not want to miss these talks! If you don’t believe me, check out the talks from SuperCon last November and you’ll be convinced — Hackaday conferences provide the best collection of hardware talks anywhere.

As with any proper hardware con, the Hackaday Supercon needed a badge, and preferably one that was electronic. This conference centered around hardware creation, and the badge was no exception.
Designed on a tight timeline, it was possible to deliver a PCB badge for the attendees but it didn’t include microcontrollers, FPGAs, or software defined radios. This blank slate was the foundation for a completely unconstrained freestyle electronics soldering session.
The front of the badge includes a matte black solder mask with Truchet tiles of traces. Put multiple badges edge-to-edge and the pattern continues indefinitely. Inside of each curved trace is a through-hole via and those makes up a grid of holes on the back of the badge. On that back side there are also two rectangular grids that presented a nice area to which hackers soldered their components.
More than a few people took up the challenge of hacking their badge, and despite a strange pitch for the through holes (0.230″), and traces that didn’t go anywhere, there were some amazing builds. I would go so far to say that the badge hacking at the Supercon was the best I’ve ever seen, and this includes DEFCON and CCC.

The 23rd DEFCON — the Western Hemisphere’s largest hacker conference — doesn’t start until tomorrow but Thursday has become the de facto start for regulars. [Brian] and I rolled into town this afternoon and are working on gathering as much information as possible about the badge challenge.
This year the badge is a 7″ vinyl record. Traditionally the badge alternates years of electronic badges and ones that aren’t. Spend your weekend pulling your hair our trying to solve the puzzles. Check out all the pictures and information (updated as we gather it) and work together collaboratively for a solution by requesting to join the crew on the Badge Hacking page.
Hackaday Breakfast on Sunday
If you’re in town Sunday morning, come nurse your hangover with [Brian], [Eric], and me. We’re headed to Va Bene Caffè at 10:30am on 8/9/15. It’s just across the street in the Cosmopolitan. Request to join this event and I’ll send you a reminder so you don’t forget. You can also hit me up on Twitter for a reminder. See you then (and don’t forget to bring hardware to show off if you have some!).
PS- The Hackaday WiFi Hat is in play. Anyone have the chops to hack it this year?
LayerOne, the first level of security. [Brian Benchoff] and I are excited to take part in our first LayerOne conference this Saturday and Sunday in Monrovia California.
Anyone in the Los Angeles area this weekend needs to get out of whatever they have planned and try out this conference that has a soul. Get the idea of a mega-con out of your head and envision a concord of highly skilled and fascinating hackers gathering to talk all things computer security. Speakers will cover topics like researching 0day exploits, copying keys from pictures taken in public, ddos attacks, social engineering, and more.
It’s not just talks, there is a ton of hands-on at LayerOne as well. I plan to finally try my hand at lock picking. Yep, I’ve covered it multiple times and we’ve even had a session led by [Datagram] at the Hackaday 10th Anniversary but I’ve never found time to give it a roll. Of course electronics are my game and [Brian] and I will both be spending a fair amount of time in the hardware hacking village. We’ll have a bunch of dev boards along with us if you want to try out an architecture with which you’re unfamiliar. This year’s LayerOne badges are sponsored by Supplyframe; we’ll have something in store for the best badge hacks we see during the weekend.
See you there!
By far the most desirable booth for the crowds at SXSW Create was the Sparkfun quadrant. We call it a quadrant because they had a huge footprint approaching 1/4 the tented area, but it was well used. They brought a number of staff down to Austin in order to give away a legit electronic badge project they call BadgerHack.
We love badge hacking. LOVE IT! But South-by isn’t purely a hardware conference so the badges aren’t made of PCBs (for shame). Add to that, free entry to Create scores you a wristband but no badge.
This is the answer to that, a badge giveaway and build-off aimed at kids but cool enough to make me feel only slightly awful for accepting one when I pretty much knew they were going to run out before the final day was done.
The USB stick PCB is, as you guessed it, an Arduino compatible loaded up with an FTDI chip and an ATmega328p which they call the BadgerStick. Accompanying this is a multiplexed 8×7 LED matrix board. Solder the three pin headers and the battery holder leads, connect to the plastic badge using the supplied double-stick tape, and you have a badge that scrolls a message in LEDs.
What an awesome giveaway. I really like it that they didn’t cut corners here. First off, the kids will value the badge much more because they had to actually assemble it rather than just being handed a finished widget. Secondly, there is the USB to serial chip and USB footprint that means they can reprogram it without any extra equipment. And an LED matrix… come on that’s just a gateway drug to learning Wiring. Bravo Sparkfun and Atmel for going this route with your marketing bucks.
The badge activity rounded out with some hardware interfacing. There’s a 3-pin socket that attendees could plug into 4 different stations around the booth. Once done they received a coupon code for Sparkfun that scrolls whenever the badge is booted up. For some at-home fun, the writeup (linked at the top) for the BadgerHack firmware is quite good. It offers advice on changing what is displayed on the badge and outlines how to build a game of Breakout with just a bit of added hardware.
Here’s a pair of LayerOne Badge hacks that actually included the RC as intended by the badge designers.
First up, we have the autonomous RC car built by [Arko]. He calls it Stanley Jr. as an homage to the Stanford DARPA Grand Challenge vehicle. It uses an Arduino shield to add a servo with an ultrasonic rangefinder on it. The lets the vehicle drive a bit, stop and scan the horizon, then drive some more. The hope is the rangefinder will keep it from running into anything. There’s a quick test run embedded after the break.
On the right is the badge hack which [Zjpahle] finished up after the contest was already over. He also chose to go with an Arduino shield, this time it’s an IMU board. But he added a standalone Arduino board to the vehicle which drives some EL wire (ground effects) and adds IR sensors to the front of the car. The IR sensors are for obstacle avoidance, and the IMU lets him tilt his badge for direction control.
We looked at the winner of the badge hacking competition on Wednesday. That hack didn’t involve the car, but used the badge as a Morse Code beacon.
