Ink-Filled Machine Badges Score Respect For Your Gear

August 5, 2017 by Dan Maloney 26 Comments

Remember the good old days when machines had a stout metal badge instead of cheap vinyl decals, and nameplates on motors were engraved in metal rather than printed on a label with a QR code? Neither do we, but these raised brass labels with color filled backgrounds look great, they’re surprisingly easy to make, and just the thing your gear needs to demand respect as a cherished piece of gear.

The ‘easy’ part of this only comes if you have access to a machine shop like [John] at NYC CNC does. To be fair, the only key machine for making these plates is a laser cutter, and even a guy like [John] needed to farm that out. The process is very straightforward — a brass plate is cleaned and coated with lacquer, which is then removed by the laser in the areas that are to be etched. The plate is dipped in an electrolyte solution for etching, cleaned, and powder coated. After curing the powder coat with a heat gun rather than an oven — a tip worth the price of admission by itself — the paint is sanded off the raised areas, the metal is polished, and a clear coat applied to protect the badge.

Plates like these would look great for a little retro-flair on a new build like this Nixie power meter, or allow you to restore a vintage machine like this classic forge blower.

All The Hardware Badges Of DEF CON 25

August 4, 2017 by Mike Szczys 22 Comments

Hardware is the future. There is no better proof of this than the hardware clans that have grown up around DEF CON, which in recent years has become known as Badgelife. I was first drawn to the custom hardware badges of the Whiskey Pirates at DC22 back in 2014. Hardware badges were being made by several groups at that time but that was mainly happening in isolation while this year the badge makers are in constant contact with each other.

A slack channel just for those working on their own DEF CON badges sprung up. This served as tech support, social hour, and feature brainstorming for all on the channel. In the past badges were developed without much info getting out during the design process. This year, there was a huge leap forward thanks to a unified badgelife API: the badge makers colluded with each on a unified communcations protocol. In the multitude of images below you frequently see Rigado modules used. These, and some others using different hardware, adopted a unified API for command and control, both through makers’ “god mode” badges, and for wireless gaming between participant badges.

I was able to get into the badge makers meetup on Thursday of DEF CON. What follows is the result of a frantic few hours trying to get through the sheer volume of badges and people to share with you all the custom hardware on display. One thing is for sure — there were literally thousands of custom badges built and sold/distributed during DEF CON. I can’t wait to see what the artisanal hardware industry will look like in five years time.

Edge-lit Pendants Show Two Layers Are Better Than One

July 28, 2017 by Donald Papp 7 Comments

Engraved acrylic lights up nicely with LED lighting. Simply engrave clear acrylic with a laser engraver, then edge-light the acrylic and watch the engraving light up. This badge made by [Solarbotics] shows how they used this principle when creating some pendants for an event that performed particularly well in the dark.

The pendants they created have two engraved acrylic panels each, and that’s about it. Two LEDs and a CR2032 battery nestle into pre-cut holes, and the engraved sides are placed face-to-face, so the outer surfaces of the pendant are smooth. By using some color-cycling RGB LEDs on one panel and blue LEDs on the other panel, the effect is that of an edge-lit outer design with a central element that slowly changes color separately from the rest of the pendant.

The design stacks the LED leads and coin cells in such a way that a simple wrap of tape not only secures things physically, but also takes care of making a good electrical connection. No soldering or connectors of any kind required. [Solarbotics] found that CR2032 cells would last anywhere between a couple of days to a week, depending on the supplier.

This design is great for using a minimum of materials, but if that’s not a priority it’s possible to go much further with the concept. Multiple layers of edge-lit acrylic were used to make numeric 0-9 display modules as well as a full-color image.

Building A DEF CON Badge In Two Weeks

July 27, 2017 by Brian Benchoff 9 Comments

DEF CON is starting right now, and this is the year of #badgelife. For the last few years, independent hardware wizards have been creating and selling their own unofficial badges at DEF CON, but this year it’s off the charts. We’ve already taken a look at Bender Badges, BSD Puffer Fish, and the worst idea for a conference badge ever, and this is only scratching the surface.

This is also a banner year for the Hackaday / Tindie / Supplyframe family at DEF CON. We’re on the lookout for hardware. We’re sponsoring the IoT village, [Jasmine] — the high priestess of Tindie — and I will be spending some time in the Hardware Hacking Village, praising our overlords and saying the phrase, ‘like Etsy, but for electronics’ far too much. We’ll be showing people how to solder, fixing badges, and generally being helpful to the vast unwashed masses.

Obviously, this means we need our own unofficial DEF CON badge. We realized this on July 10th. That gave us barely more than two weeks to come up with an idea for a badge, design one, order all the parts, wait on a PCB order, and finally kit all the badges before lugging them out to DEF CON. Is this even possible? Surprisingly, yes. It’s almost easy, and there are zero excuses for anyone not to develop their own hardware badge for next year’s con.

DEF CON Badgelife: Someone Finally Did It

July 18, 2017 by Brian Benchoff 11 Comments

Badgelife is the celebration of electronic conference badges, a way of life that involves spending far too much time handling the logistics of electronics manufacturing, and an awesome hashtag on Twitter. Badgelife isn’t a new thing; it’s been around for a few years, but every summer we see a massive uptick in the lead up to Def Con.

For the last few years, the designers and engineers deep into Badgelife have had the same conversation dozens of times. One person says, “you know, someone should build a badge that’s a quadcopter.” Another person replies, “Can you imagine how annoying that would be? You’d be putting ten thousand people in a room during the closing ceremonies at DefCon, and a few dozen people would have quadcopters. It would be horrible” Yes, there have been plans to build a quadcopter badge for the last few years, but cooler heads prevailed.

Someone finally did it. The wearable electronic conference badge that’s also a quadcopter is finally here. It’s the work of [b1un7], and it’s going to be exactly as annoying as you would expect.

This badge is actually two PCBs, the first being the quadcopter itself, the second being the joystick/controller. The quad is shaped like the familiar jolly roger found in most Whiskey Pirate badges ([b1un7] hangs with that crew), and the controller is a pirate’s treasure map loaded up with joysticks, buttons, and radios. The motors for this quad appear to be brushed, not brushless, and it looks like the arms of the quad have some space for obnoxiously bright LEDs.

This is an awesome badge but it’s still [b1un7]’s first attempt at making a badge. Right now, there’s still a bit of work to do — there’s only one week until Defcon — but with any luck [b1un7] will have 25 of these wearable electronic conference badges buzzing around. It’s a terrible idea and we love it.

Friday Hack Chat: BadgeLife

July 12, 2017 by Brian Benchoff 2 Comments

For the last few years at DEF CON, we’ve seen the emergence of an entire community of badge creators. These aren’t official badges — good news, since the official DEF CON badge will probably be an unpuzzling piece of laser cut acrylic this year. Lucky for us this is the biggest year yet for independent electronic badges. This is BadgeLife, the fine art of designing and building hundreds of badges for eager conference goers.

This Friday, we’ll be hosting a Hack Chat with a few of the folks tapped into BadgeLife. [Whitney Merrill], lawyer, hacker, and overseer of the Crypto & Privacy village will be joining us talking about this year’s badge, the puzzle she designed, and what BadgeLife really means. Also joining us will be [Karl Koscher], research scientist and co-organizer of the Crypto and Privacy village.

Also on deck will be the creators of this year’s Bender Badge. Last year, AND!XOR created one of the most popular electronic conference badges in recent memory. This year, the Bender Badge is getting an upgrade with Blast Processing, a quart of tequila, and two dozen amyls.

We’re proud to note that Hackaday.io has become an unofficial repository for all the best badges from the BadgeLife community. The Hunter S. Rodriguez badge is on there, as is the Ides of DEF CON. As the creator of the most innovative and desirable badge this year, I will also be attending this Hack Chat discussing the trials and tribulations of developing and shipping hardware on a very condensed schedule.

While the focus of this BadgeLife Hack Chat is developing electronic conference badges for DEF CON, it could have easily been called ‘Electronic Design’. There’s a massive amount of work that goes into each of these badges from design to production, and all of it is highly relevant to any hardware developer.

Here’s How To Take Part:

Our Hack Chats are live community events on the Hackaday.io Hack Chat group messaging. This Hack Chat will take place at noon Pacific time on Friday, July 14th. Confused about where and when ‘noon’ is? Here’s a time and date converter!

Log into Hackaday.io, visit that page, and look for the ‘Join this Project’ Button. Once you’re part of the project, the button will change to ‘Team Messaging’, which takes you directly to the Hack Chat.

You don’t have to wait until Friday; join whenever you want and you can see what the community is talking about.

DEF CON BadgeLife: Blinky Bling

July 10, 2017 by Brian Benchoff 6 Comments

This is the biggest year yet for unofficial electronic conference badges. We’re calling it the year of Badgelife, and for the next few weeks, we’re going to be taking a look at the unofficial conference badges being deployed at this year’s DEF CON.

[Mr Blinky Bling] a.k.a. [Benn Hibben] has created his own badge for this year’s con. On board is a bunch of LEDs, WiFi, and capacitive buttons. It’s a WiFi badge for all your AP scanning and deauth needs. The electronics for this badge are a bit more complicated than simply throwing an ESP8266 on a board and calling the design done. The capacitive touch functionality is being handled by an ATTiny88, the OLED display is handled by an ATMega32U4, wireless functions are done with an ESP8266, and there are a few bits and bobs for a LiPo battery.

This WiFi Badge is the focus of an astonishingly successful Kickstarter (ending in just a few hours), and [Mr Blinky Badge] already has enough backers to move 200 badges. This is really a spectacular amount of work; it’s one thing to build a single prototype for an electronic conference badge, but it’s another matter entirely to put a badge into production, source all the parts, handle the assembly, and finally ship all these badges to Kickstarter backers and conference attendees.

If the challenge of building and deploying hundreds of electronic conference badges sounds like fun, you’re in luck. This Friday, we’ll be hosting a Hack Chat with some of the creators of this year’s unofficial DEF CON badge creators. There’s a lot you can learn from these folks, and a lot of very cool badges that will make an appearance at this year’s Def Con.
