Hackaday Links: August 11, 2019

By the time this goes to press, DEFCON 27 will pretty much be history. But badgelife continues, and it’d be nice to have a way of keeping track of all the badges offered. Martin Lebel stepped up to the challenge with a DEF CON 27 badgelife tracker. He’s been tracking the scene since March, and there are currently more than 170 badges, tokens, and shitty add-ons listed. Gotta catch ’em all!

Nice tease, Reuters. We spotted this story about the FAA signing off on beyond-visual-line-of-sight, or BVLOS, operation of a UAV. The article was accompanied by the familiar smiling Amazon logo, leading readers to believe that fleets of Amazon Prime Air drones would surely soon darken the skies with cargoes of Huggies and Tide Pods across the US. It turns out that the test reported was conducted by the University of Alaska Fairbanks along an oil pipeline in the Last Frontier state, and was intended to explore medical deliveries and pipeline surveillance for the oil industry. The only mention of Amazon was that the company reported they’d start drone deliveries in the US “in months.” Yep.

Ever wonder what it takes to get your widget into the market? Between all the testing and compliance requirements, it can be a real chore. Nathaniel tipped us off to a handy guide written by his friend Skippy that goes through the alphabet soup of agencies and regulations needed to get a product to market – CE, RoHS, WEEE, LVD, RED, CE for EMC. Take care of all that paperwork and you’ll eventually get a DoC and be A-OK.

A French daredevil inventor made the first crossing of the English Channel on a hoverboard on Sunday. Yes, we know it’s not an “actual” hoverboard, but it’s as close as we’re going to get with the physics we have access to right now, and being a stand-upon jet engine powered by a backpack full of fuel, it qualifies as pretty awesome. The report says it took him a mere 20 minutes to make the 22-mile (35-km) crossing.


We had a grand time last week around the Hackaday writing crew’s secret underground lair with this delightful Hackaday-Dilbert mashup-inator. Scroll down to the second item on the page and you’ll see what appears to be a standard three-panel Dilbert strip; closer inspection reveals that the text has been replaced by random phrases scraped from a single Hackaday article. It looks just like a Dilbert strip, and sometimes the text even makes sense with what’s going on in the art. We’d love to see the code behind this little gem. The strip updates at each page load, so have fun.

And of course, the aforementioned secret headquarters is exactly what you’d picture – a dark room with rows of monitors scrolling green text, each with a black hoodie-wearing writer furiously documenting the black arts of hacking. OpenIDEO, the “open innovation practice” of global design company IDEO, has issued a challenge to “reimagine a more compelling and relatable visual language for cybersecurity.” In other words, no more scrolling random code and no more hoodies. Do you have kinder, gentler visual metaphors for cybersecurity? You might win some pretty decent prizes for your effort to “represent different terms and ideas in the cybersecurity space in an accessible and compelling way.”

DEF CON 27: The Badge Talk; Or That One Time Joe Grand Sourced 30,000 Gemstones

Yesterday we published a first look at the hardware found on the DEF CON 27 badge. Sporting a magnetically coupled wireless communications scheme rather than an RF-based one, and an interesting way to attach the lanyard both caught my attention right away. But the gemstone faceplate and LED diffuser has its own incredible backstory you don’t want to miss.

This morning Joe Grand — badge maker for this year and many of the glory years of hardware badges up through DC18 — took the stage to share his story of conceptualizing, prototyping, and shepherding the manufacturing process for 28,500 badges. Imagine the pressure of delivering a delightful concept, on-time, and on budget… well, almost on budget. During the talk he spilled the beans on the quartz crystal hanging off the front side of every PCB.

Hands-On: AND!XOR DEF CON 27 Badge Ditches Bender, Adopts Light Pipes

The newest offering from the AND!XOR team is out and it delivered exactly what hardware badges were missing: light pipes. No joke, the DEF CON 27 edition AND!XOR badge will be most recognizable because of two arcs of light pipe material blinging RGB goodness in three dimensions. But if you can peel your eyes away from that oddity there’s a lot to love about the new design.

CampZone 2019 Badge Is Begging To Become A Huge Billboard

What has 256 full-colour LEDs, everyone’s favorite Lithium battery form factor, wireless connectivity, and hangs around your neck? It’s the CampZone 2019 badge that turns all attendees into a really fun billboard — but can the attendees hack themselves into one massive display?

One of Europe’s larger events for the gaming community,  CampZone is hosted in Netherlands and runs from July 26th to August 5th. It’s a typical large summer camp, and caters for those who intersect gaming and hacking with HackZone, a decent sized hacker camp within a camp. I’ve been fortunate enough to get my hands on a CampZone 2019 badge, dubbed the I-Pane, let’s take a look at what they managed to pack into this electronic conference badge.

Hunting Replicants With The 2019 LayerOne Badge

Blade Runner showed us a dystopian megatropolis vision of Los Angeles in the far-off future. What was a distant dream for the 1982 theater-goes (2019) is now our everyday. We know Los Angeles is not perpetually overcast, flying cars are not cruising those skies, and replicants are not hiding among the population. Or… are they?

The LayerOne conference takes place in greater Los Angeles and this year it adopted a Blade Runner theme in honor of that landmark film. My favorite part of the theme was the conference badge modeled after a Voight-Kampff machine. These were used in the film to distinguish replicants from humans, and that’s exactly what this badge does too. In the movies, replicants are tested by asking questions and monitoring their eyes for a reaction — this badge has an optional eye-recognition camera to deliver this effect. Let’s take a look!

The Multi Pass Def Con Indie Badge Has A European Flavour

It has been fascinating to watch the rise of the #BadgeLife community in North America, and a little sad when viewed from a European perspective that their creative vibrancy has not quite fully made it across the Atlantic. It’s pleasing therefore to report on something traveling in the opposite direction. We’ve found a #BadgeLife creation that’s as American as they come, but which hides a bit of European flavor under its shell.

The DC27 Multi Pass is a Def Con indie badge themed as a prop from the film The Fifth Element. That is not its only trick though, because under the hood it runs the ESP32-based badge.team, the badge software platform created by the team from the Netherlands who brought us the SHA 2017 and Hacker Hotel 2019 badges. Like those two it sports an e-ink screen and a set of touch buttons, which they’ve very neatly incorporated into the Multi Pass design. The badge.team ecosystem brings with it a fully-functional and stable hackable badge platform with MicroPython apps and an app library (We won’t call it a store, it’s all free!) referred to as the hatchery. There is even a Hackaday logo nickname, should you have one of these badges and wish to identify yourself as a reader.

The launch of a new #BadgeLife badge is always cool, but with the best will in the world it is not in itself news. Where this one does, however, get interesting is that it proves that badge.team is a viable route to getting full event badge functionality into an indie badge without the heartache of creating a software platform. It also serves as a fascinating perspective on why the USA has spawned its artistic badge scene while Europe has less diversity. The whole Def Con experience is extremely expensive, while European hacker camps are relatively not so. There is no need for a European hacker to finance their trip to EMF Camp by selling badges, so for many people, the impetus to create finds its outlet in other directions. It would be nice to think that European badge scene will in time evolve as far as the US one, but meanwhile, it’s good to see the Netherlands community supplying their platform to what we think will be a very interesting Def Con indie badge.

Hackaday Superconference: Pushing The Boundaries Of PCB Artwork With Brian Benchoff

The artistic elite exists in a stratum above we hoi polloi, a world of achingly trendy galleries, well-heeled collectors, and art critics who act as gatekeepers to what is considered the pinnacle du jour of culture. Artistic movements that evolve outside this bubble may be derided or ignored as naive and unsophisticated, even in complete denial of their raw creative edge. When they are discovered by the establishment a few of their artists are selected and anointed, while inevitably the crucible in which they were formed is forgotten. On the streets of Bristol the incredible work of far more graffiti artists can be seen than just that of Banksy.

Our community has an art form all of its own, in the guise of PCB artwork and the #BadgeLife community. One day you will see electronic badges from darlings of the art world behind glass in those trendy galleries, but for now they live in glorious abundance in the wild. Here at Hackaday we are lucky enough to have in Brian Benchoff a colleague who is pushing the boundaries of PCB art, and at the Hackaday Superconference he took us through one of his more recent pieces of work.

Brian's pad printer.
Brian’s pad printer.

The colour palette of a typical printed circuit board is limited by the combination of fibreglass, copper, soldermask, plating, and silkscreen its designer selects. Thus while the variety of soldermask colours and plating materials can make for an eye-catching work, they have remained a colour-tinted near monochrome. The Holy Grail of the PCB artist has been to step into the world of full colour, and Brian has been pursuing that goal by exploring pad printing to produce extra colours beyond the sodermask..

It’s a subject he’s written about here in the past, and he introduces it in the talk with a look at existing badge artwork and a mention of an expensive commercial inkjet process before considering the type of printing you see daily on the sides of promotional pens. Those company titles are deposited on pens using pad printing, an offset process in which ink is first deposited upon a photo-etched metal plate before being picked up on a silicone rubber pad for transfer to the object to be printed. It’s not the panacea for all coloured-PCB tasks, but for adding relatively small blocks of pigment to an otherwise monochromatic board it can be very successful.

The eye-catching Kiss -themed Tindie badges.
The eye-catching Kiss -themed Tindie badges.

Brian’s examples are a panelised set of Tindie badges as a homage to the rock band Kiss, and his Tide pod addon containing a serial number in an EEPROM that was part of a Blockchain-inspired game. The Kiss Tindie badges use black soldermask with extensive white silkscreen and a modest area of red pad printing for the stage makeup, while the Tide addon makes clever use of the same swoosh printed in alternate colours at 180 degrees to each other.

In both cases there is some labour involved in creating the prints, and as his detailed write-up of printing the Tide pods reminds us, the process of creating the printing plate is not exactly an easy one. But it remains the best way yet to add extra colours to a board without paying a small fortune for the inkjet process, and if you’d like to put your own designs at the bleeding edge of PCB art you might wish to read his writeups and watch the video below the break.

This is just one example of the kind of manufacturing techniques, and electronic design principles on display at the Hackaday Superconference. There’s another Supercon just around the corner, so grab your ticket and send in your own talk proposal right away!
