Hackaday Podcast 067: Winking Out Of IoT, Seas Of LEDs, Stuffing PCBs, And Vectrex Is Awesome

Hackaday editors Mike Szczys and Elliot Williams explore the coolest hacks of the past 168 hours. The big news this week: will Wink customers pony up $5 a month to turn their lights on and off? There’s a new open source design for a pick and place machine. You may not have a Vectrex gaming console, but there’s a scratch-built board that can turn you oscilloscope into one. And you just can’t miss this LED sign technology that programs every pixel using projection mapping.

The United States Air Force Would Like You To Hack Into Their Satellite

The Air Force is again holding its annual “Space Security Challenge” where they invite you to hack into a satellite to test their cybersecurity measures. There are actually two events. In the first one, $150,000 is up for grabs in ten prizes and the final event offers a $100,000 purse divided among the three top participants (first place takes $50,000).

Before you get too excited, you or your team has to first qualify online. The qualification event will be over two days starting May 22. The qualifying event is set up a bit like the TV show Jeopardy. There is a board with categories. When a team solves a challenge in a category it receives a flag that is worth points as well as getting to unlock the next challenge. Once a challenge is unlocked however, any team could potentially work on it. There are more rules, but that’s the gist of it. At the end of the event, the judges will contact the top 10 teams who will then each have to submit a technical paper.

Pictorial Guide To The Unofficial Electronic Badges Of DEF CON 27

DEF CON has become the de facto showplace of the #Badgelife movement. It’s a pageant for clever tricks that transform traditional green rectangular circuit boards into something beautiful, unique, and often times hacky.

Today I’ve gathered up about three dozen badge designs seen at DC27. It’s a hint of what you’ll see in the hallways and meetups of the conference. From hot-glue light pipes and smartphone terminal debugging consoles to block printing effects and time of flight sensors, this is a great place to get inspiration if you’re thinking of trying your hand at unofficial badge design.

If you didn’t catch “The Badgies” you’ll want to go back and read that article too as it rounds up the designs I found to be the craziest and most interesting including the Car Hacking Village, Space Force, SecKC, DC503, and Frankenbadge. Do swing by the Hands-On articles for the AND!XOR badge and for [Joe Grand’s] official DC27 badge. There was also a lot of non-badge hardware on display during Hackaday’s Breakfast at DEF CON so check out that article as well.

Enough preamble, let’s get to the badges!

After The Con: Da Bomb Badge Post Mortem

We’ve reported on the world of electronic badges here at Hackaday since their earliest origins in [Joe Grand]’s work for DEF CON 14 in 2006. In that time we’ve seen an astonishing variety of creations, covering everything from abstract artwork to pure functionality in a wearable device. But it’s not been quite so often that we’ve looked at the other side of the BadgeLife coin, so it’s fascinating to read [John Adams]’ account of the work that went into the production of this year’s 500-piece run of the Da Bomb DEF CON indie badge.

In it, [John] goes over scheduling worries, component sourcing issues, PCB assembly delays, and an in-depth look into the finances of such a project. In case anyone is tempted to look at Badgelife as the route to millions, it rapidly becomes apparent that simply not losing too much money is sometimes the best that can be hoped for. There were a few design problems, one of them being that the SAO I2C bus was shared with the LED controller, resulting in some SAOs compatibility issues. In particular the AND!XOR DOOM SAO had its EEPROM erased, creating something of a headache for the team.

A surprise comes in the distribution: obviously shipping is expensive, so you’d think badge pick-ups at the con would be straightforward alternative. Unfortunately, they became something of a millstone in practice, and organising them was a Herculean task. Astoundingly, some paying customers didn’t bother turn up for their badges. Which was especially infuriating since the team lost valuable conference time waiting for them.

Some of you are BadgeLife creators and will nod sagely at this. Still more of you will wish you were BadgeLife creators and find it a useful primer. For everyone else it’s a fascinating read, and maybe makes us appreciate our badges a bit more.

The images may have departed, but just to return to the origins of BadgeLife, here’s our coverage of that first [Joe Grand] badge.

The Badgies: Clever, Crazy, And Creative Ideas In Electronic Design

Engineering creativity comes to life when you have to design around a set of constraints. We can do just about anything with enough time, talent, and treasure, but what can you do when shackled with limitations? Some of the most creative electronic manufacturing tricks spring to life when designing conference badges, as the ability to built multiples, to come in under budget, and most importantly to have the production finished in time are all in play.

This happens at conferences throughout the year and all over the globe, but the highest concentration I’ve seen for these unique pieces of art is at DEF CON every year. I loved seeing dozens of interesting projects this year, and have picked a handful of the coolest features on a badge to show off in this article. I still love all the rest, and have a badge supercut article on the way, but until then let’s take a look at an RC car badge, a different kind of blinky bling, and a few other flourishes of brilliance.

NFC Business Cards To FPGA Cubes, Skull Badges To Bandoliers, Here’s The Hardware From Breakfast At DEF CON

We had our biggest Breakfast at DEF CON ever on Sunday. So big, in fact, that the carefully laid plans went awry immediately.

This is the fifth year we’ve hosted the event, which kicks off the final day of DEF CON with some hardware show-and-tell. We really thought we had it all figured out, since this time we actually booked a space in Paris hotel. For the first three years we were just banditing the space — asking everyone to show up at this place and it’ll become an event. Last year we planned to have it in the Hardware Hacking Village, but the casino stopped us from bringing in pastries that morning and we ended up camping out in a dining area that wasn’t open until the afternoon.

Last weekend we had a cafe booked, with pastries and coffee on order. The only problem is that you are all too awesome. We had a couple hundred people show up and the cafe didn’t want us standing, which limited our space to the number of booth seats available. No worries, as is the tradition we spilled out into a lounge area on the casino floor and enjoyed ourselves!

Here’s some of the hardware that showed up at this gathering.

Hands-On: Queercon 16 Hardware Badge Shows Off Custom Membrane Keyboard

Year over year, the Queercon badge is consistently impressive. I think what’s most impressive about these badges is that they seemingly throw out all design ideas from the previous year and start anew, yet manage to discover a unique and addictive aesthetic every single time.

This year, there are two hardware badges produced by the team composed of Evan Mackay, George Louthan, Tara Scape, and Subterfuge. The one shown here is nicknamed the “Q” badge for its resemblance to the letter. Both get you into the conference, both are electronically interactive, but this one is like a control panel for an alternate reality game (ARG) that encourages interactivity and meaningful conversations. The other badge is the “C” badge. It’s more passive, yet acts as a key in the ARG — you cannot progress by interacting with only one type of badge, you must work with people sporting both badge types so that Queercon attendees who didn’t purchase the Q badge still get in on the fun.

The most striking feature on this badge is a custom membrane keyboard tailored to playing the interactive game across all badges at the conference. But I find that the eInk screen, RJ12 jack for connectivity, and the LED and bezel arrangements all came together for a perfect balance of function and art. Join me after the break for a closer look at what makes this hardware so special.
