Hands-On: Internet Of Batteries Quantum Badge Brings Badgelife Add-Ons The Power And Internet They Crave

Our friends in the Whiskey Pirates crew sent me the unofficial DEF CON badge they built this year. The Internet of Batteries QUANTUM provides power and connectivity to the all-important add-on badges of DC28. The front of the badge is absolutely gorgeous to the point I don’t really want to solder on my add-on headers and disrupt that aesthetic.

The gold-plated copper makes for a uniformed and reflective contrast to the red solder mask which occupies the majority of the front. Here we see the great attention to detail that [TrueControl] includes in his badges. The white stripe of silk screen separating the two colors is covered by some black detailing tape that looks much better than the white.

The antenna of the ESP32 module poking out the underside of the gold cover end of the badge gets its own rectangle of the holographic sticker material, the same as the sheet of stickers that was included in the box. Both decals are small details that make a huge difference to your eye.

The line of nine RGB LEDs have black bezels which goes along with the black stripe motif and underscores the typography of the badge name. These lights are hosted on a daughter board soldered to the underside of the badge with a slot for the LEDs to pass through. They are addressed in a 2×15 matrix that is scanned on the low side by the PSoC5 that drives the badge. This low-res image shows that daughter board before the lithium cell is placed.

Hackaday Links: April 7, 2019

It’s April, which means all the people responsible for doubling the number of badges at DEF CON are hard at work getting their prototypes ready and trying to fund the entire thing. The first one out of the gate is Da Bomb, by [netik] and his crew. This is the same team that brought you the Ides of DEF CON badge, a blinky wearable multiplayer game that’s SPQR AF. Da Bomb is now a Kickstarter campaign to get the funding for the run of 500, and you’re getting a wearable badge filled with puzzles, Easter eggs, and a radio-based sea battle game that obviously can’t be called Battleship, because the navy doesn’t have battleships anymore.

Speaking of badges and various badge paraphernalia, there’s a new standard for add-ons this year. The Shitty Add-On V.1.69bis standard adds two pins and a very secure shrouded connector that solves all the problems of last year’s standard. [AND!XOR] just released a Shitty Brooch that powers all Shitty Add-Ons with a CR2032 battery. All the files are up on the Gits, so have fun.

You can 3D print anything if you don’t mind dealing with supports. But how to remove supports? For that [CCecil] has a great tip: use Chap stick. This is a print that used supports and it’s perfectly clean, right off the bed. By inserting a suspend (M600) command at the z-height of the top of the interface layer, then adding Chap stick on the top layer, everything comes off clean. Neat.

Speaking of 3D printing, here’s a project for anyone with the patience to do some serious modeling. It’s a pocket Soviet record player, although I think it’s more properly called a gramophone. It’s crank powered, so there’s a spring in there somewhere, and it’s entirely acoustic with zero electronics. Yes, you’re going to need a needle, but I’d be very interested in seeing somebody remake this using modern tools and construction materials.

Introducing The Shitty Add-On V1.69bis Standard

The last few years have seen a rise of artistic PCBs. Whether these are one-off projects with a little graphic on the silkscreen or the art of manufacturing and supply chains, these fancy PCBs are here to stay. Nowhere is this more apparent than the loose confederation of Badgelife enthusiasts, a hardware collective dedicated to making expressive and impressive electronic baubles for various hacker conferences. Here, hundreds of different hardware badges are created every year. It’s electronic art, supported by a community.

Some of these badges aren’t technically badges, but rather small, blinky add-ons meant to connect to a main badge, and these add-ons are all backed by a community-derived standard. The Shitty Add-On Standard is how you put smaller PCBs onto bigger PCBs. It is supported by tens of thousands of badges, and all of the people who are spending their free time designing electronic conference badges are using this standard.

It’s been more than a year since the Shitty Add-On standard was created, and in that time the people behind the work have seen the shortcomings of the first edition of the standard. Mechanically, it’s not really that strong, and it would be neat if there were a few more pins to drive RGB LEDs. This has led to the creation of the latest revision of the Shitty Add-On Standard, V.1.69bis. Now, for the first time, this standard is ready for the world to see.

Ah, crap. We lost a good one, people. [Samm Sheperd] passed away last month. We’ve seen his stuff before, from a plane with a squirrel cage fan, to completely owning a bunch of engineering students by auditing a class. The obit is available as a Google Doc, and there’s a Samm Sheperd Memorial Fund for the Big Lake Youth Camp in Gladstone, Oregon.

FranLab is closing down! Fran is one of the hardware greats, and she’s being evicted. If you’ve got 2000sqft of workshop space in Philly you’d like to spare, you know who to talk to. There will, probably, be a crowdfunding thing going up shortly, and we’ll post a link when it’s up.

The Parallax Propeller is probably one of the most architecturally interesting microcontrollers out there. It’s somewhat famous for being a multi-core chip, and is commonly used in VGA generation, reading keyboards, and other tasks where you need to do multiple real-time operations simultaneously. The Parallax Propeller 2, the next version of this chip, is in the works, and now there’s real silicon. Everything is working as expected, and we might see this out in the wild real soon.

Thought artistic PCBs were just a con thing? Not anymore, I guess. There has been a lot of activity on Tindie with the Shitty Add-Ons with [TwinkleTwinkie] and [Potato Nightmare] releasing a host of very cool badges for your badges. Most of these are Shitty Add-Ons, and there will be an update to the Shitty Add-On spec shortly. It’s going to be backwards-comparable, so don’t worry.

Unnecessary drama!?! In my 3D printing community?!? Yes, it’s true, there was a small tiff over the Midwest RepRap Festival this week. Here’s what went down. You got three guys. John, Sonny, and Steve. Steve owns SeeMeCNC, based in Goshen, Indiana. John worked for SeeMeCNC until this year, and has been the ‘community manager’ for MRRF along with Sonny. Seeing as how the RepRap Festival is the only thing that ever happens in Goshen, Steve wanted to get the ball rolling for next year’s MRRF, so he sent out an email, sending the community into chaos. No, there’s not some gigantic fracture in the 3D printing community, John and Sonny, ‘were just slacking’ (it’s five months out, dudes. plenty of time.), and Steve wanted to get everything rolling. No problem here, just a bunch of unnecessary drama in the 3D printing community. As usual.

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.

This Is The Year Conference Badges Get Their Own Badges

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.

SiFive raised $50 Million in funding. SiFive is a semiconductor working on two fronts: they want to democratize silicon prototyping, and they’re the people making the HiFive series of microcontrollers and SoCs. The HiFives are built on the RISC-V instruction set, a Big-O Open instruction set for everything from tiny microcontrollers to server CPUs. With RISC-V, you’re not tied to licensing from ARM or their ilk. Recently SiFive introduced an SoC capable of running Linux, and the HiFive 1 is a very fast, very capable microcontroller that’s making inroads with Nvidia and Western Digital. The new round of funding is great news for anyone who wants Open Source hardware, and the silicon prototyping aspect of it is exceptionally interesting. Great news for SiFive.

Guess what’s in just a few weekends? The Vintage Computer Festival Southeast. The VCFSE is Hotlanta’s own vintage computer festival, with a whole host of speakers, exhibits, and consignment to tickle those vintage dopamine receptors. On deck for the speakers is [Michael Tomczyk], one of the people responsible for the VIC-20, and [Scott Adams], no the other [Scott Adams], creator of adventure-style games for personal computers but not that adventure-style game. The exhibits will include Japanese retro computers, simulating an ENIAC and a mechanical keyboard meetup. If you’re around Georgia, this is an event worth attending.

Conference season is just around the corner, and you know what that means. It’s time to start ramping up for #badgelife. What is badgelife? It’s a hardware demoscene of electronic conference badges. This year, the badgelife scene has stumbled upon something everyone can get in on. Add-ons! They’re electronic hats (or shields, or capes) for all the badges. Physically, it’s a 2×2 pin header. Electronically, it’s power, ground and I2C. Want to prototype your own add-on? Good news, there’s a development board.

The Titius-Bode law states the semi-major axes of planets follow a geometric progression. The (simplified, incorrect) demonstration of this law states Mercury orbits at 0.25 AU, Venus at 0.5 AU, Earth at 1 AU, Mars at 2 AU, and continues to the outer planets. The Titius-Bode law is heavily discredited in the planetary science community, and any paper, talk, or manuscript is rejected by scientific editors out of hand. The Titius-Bode law is the planetary science equivalent of flat Earth conspiracy theories and Nazi moon bases; giving any consideration to the idea confirms you’re a moron. This week, some consulting firm posted something that is the Titius-Bode law on their blog. Why? So it could be submitted to Hacker News for that sweet SEO. This submission was upvoted to the top position, and is a wonderful springboard to argue an interesting point on media literacy. I posit the rise of news aggregators (facebook, twitter, digg, reddit, and HN), is the driving force behind ‘fake news’ as lay people become the gatekeepers. Prove me wrong.

The Department of Homeland Security has confirmed there are cell-site simulators (Stingrays, IMSI-catchers, or otherwise known as your own private cell phone base station) around Washington DC. It’s unknown who is operating these simulators, or even where they are. There are two things to read between the lines with this information: Duh, there are rogue Stingrays in DC. Holy crap duh. I bet there are also some around midtown Manhattan. You can buy the stuff to do this on eBay. Personally, I’ve found half a dozen Stingrays or other rogue cell stations this year (guess where?). Second, why is this a news item now? Is this a signal that the DHS will start clamping down on stuff you can buy on eBay? Hop to it, people; cellular hardware is a great way to make a liquid nitrogen generator.
