Hardware Tribes Growing Up Around Artisanal Electronics

Consumer electronics are design beasts that must serve many masters. There’s a price point for the product itself, a ceiling for the feature set (lest it not be ‘user friendly’), and to take the risk of actually manufacturing something there needs to be proof of the market. A lot of great things make it through this process, but some really unique and special gear goes completely around it.

So is the story of this AND!XOR hardware badge being built for DEF CON 25. This is not the official conference badge, but the latest in a growing trend of hardware/firmware engineers and hackers who design their own custom gear for the conference, trying to one-up not just the official badge, but the other hardware tribes doing the same. This unique hardware excitement is a big reason that Hackaday has developed electronic badges for our conferences.

The new badge is a mashup of Bender from Futurama and Raoul Duke from Fear and Loathing in Las Vegas, presents something of monstrosity to hang around your neck. That has certainly never stopped us from having one of these bouncing around our necks as we pound the cattle paths from talk to talk (and the DC23 vinyl record was way more unwieldy anyway).

Bender’s forehead display has now been upgraded from a diminutive OLED to a generous color LCD display. The 433 MHz which used the spring antenna on the previous badge has given way to a Bluetooth Low Energy. The BLE is built into the Rigado BMD-300 SOC that is now in conrol of the badge. We can’t wait to see the shenanigans unlocked with this new hardware — they’re already showing of crazy animations, retro gaming, and teasing a huge multiplayer game with all the badges. Finally, the “Secret Component” at the bottom of their components list delivers the je ne sais quoi to the whole project.

Fans of AND!XOR have already thrown their weight behind it. Unofficial badges have been unavailable to a wider group or only offered in flash-sales that pop up during the con. Last year the team was met with a huge mob throwing money at their supply of 175 badges. Now the AND!XOR team has grown to five people toiling away to make the design, the easter-egg laden firmware, and the manufacturing process better than the amazing work of last year. They just launched a crowd funding campaign on Tuesday and immediately blew past their goal about five times over.

We’re hoping to get our mitts on one of these ahead of DEF CON to give you an early look at what these hardware artists have accomplished. If you’re part of another hardware tribe building custom electronics for the love of it, we’d really like to hear from you. This goes for any conference — we know of at least one other in progress.

A Real Star Trek Communicator Badge

Star Trek has never let technology get in the way of a good story. Gene Roddenberry and the writers of the show thought up some amazing gadgets, from transporters to replicators to the warp core itself. Star Trek: The Next Generation brought us the iconic communicator badge. In 1987, a long-range radio device which could fit in a pin was science fiction. [Joe] is bringing these badges a bit closer to the real world with his entry in the 2017 Hackaday Sci-Fi Contest.

trek-thumbThe first problem [Joe] dealt with was finding a radio which could run from watch batteries, and provide decently long-range operations. He chose the HopeRF RFM69HCW. Bringing fiction a bit closer to reality, this module has been used for orbital communications with low-cost satellites.

The Badge’s processor is a Teensy LC. [Joe] is rolling his own Teensy, which means using bootloader chips from PJRC, as well as the main microcontroller. Kicking the main micro into operation is where [Joe] is stuck right now. Somewhere between the breadboard and the first spin of the surface mount PCB things went a bit sideways. The oscillators are running, but there are no USB communications. [Joe] is trying another board spin. He made a few improvements and already has new boards on the way. Switching to a toaster oven or skillet paste and solder setup would definitely help him get the new badges up and running.

The Best Conference Badge Of 2017 Is A WiFi Lawn

It’s February, conference season hasn’t even started yet, and already there’s a winner of the best electronic badge of the year. For this year’s MAGfest, [CNLohr] and friends distributed 2,000 ESP8266-based swag badges.

These custom #badgelife badges aren’t. Apparently, MAGFest wouldn’t allow [CNLohr] to call these devices ‘badges’. Instead, these are ‘swadges’, a combination of swag and badges.  On board theses swadges is an ESP-12, a quartet of RGB LEDs, and buttons for up, down, left, right, A, B, Select, and Start. The swadge is powered by two AA batteries (sourced from Costco of all places), and by all accounts the badge was a complete success.

[CNLohr] is one of the great ESP8266 experts out there, and one of the design goals of this badge is to have all of these swadges communicate over raw WiFi frames. This turned out to be a great idea – using normal WiFi infrastructure with two thousand badges saturated the spectrum. The control system for was simply three badges, one per WiFi channel, that tells all the badges to change the color of the LEDs.

The swadge was a complete success, but with a few hundred blinkey glowey WiFi devices, you know [CNLohr] is going to come up with something cool. This time, he turned his lawn into a rave. About 175 swadges were laid out on the lawn, all controlled by a single controller swadge. The color of the LEDs on each swadge in the yard changes in response to the WiFi signal strength. By swinging the controller badge around his head, [CNLohr] turned his yard into a disco floor of swirling blinkieness. It looks awesome, although it might not visualize WiFi signals as well as some of [CNLohr]’s other ESP hacks.

This is a fantastic build and was well received by everyone at MAGFest. Be sure to check out the videos below, they truly show off the capabilities of this really cool piece of wearable hardware.

Hackaday Links: January 8, 2017

What do you get when mindless automatons with no capacity for reason or logic converse? While you discuss that in the comments, here are two chatbots on Twitch. The highlights? A few hours ago they were doing the cutesy couple, “‘I love you more!’, ‘No, I love you more!'” thing. This was ended by, “Error, cannot connect to server.” Even robot love is not eternal.

3D printer nozzles wear out. Put a few hundred hours on a brass nozzle, and you’re not going to get the same print quality as when you started. This has led to stainless and silly-con carbide nozzles. Now there’s a ruby nozzle. It’s designed by [Anders Olsson], the same guy who’s using an Ultimaker to print neutron shielding. This guy is a nuclear engineer, and he knows his stuff. This is a nozzle designed to not grind contaminants into extruded plastic, and it looks cool, too.

This is the eighth day of the year, but the guild of independent badge makers of DEF CON are already hard at work. AND!XOR is working on the DC25 badge, that promises to be bigger, badder, and more Bender. I’m loving the Hunter S. Bender theme.

Anyone can design a PCB, but how do you panelize multiple PCBs? There’s a lot to consider – routing, mouse bites, and traces for programming the board while still panelized. This is the best solution we’ve seen. It’s a GUI that allows you to organize Gerbers on a panel, rotate them, add routes and cutouts, and generally do everything a board house does. It’s all Open Source and everything is available on GitHub.

[ducksauz] found a very old ‘computer trainer’ on eBay. It’s a DEC H-500, built to explain the basics of digital electronics and semiconductors to a room full of engineering students. It is an exceptionally beautiful piece of equipment with lovely hand-drawn traces and ‘surface mounted’ 7400 chips mounted on the back side.

Solving Hackaday’s Crypto Challenge

Although I’ve been to several DEF CONs over the past few years, I’ve never found time to devote to solving the badge. The legendary status of all the puzzles within are somewhat daunting to me. Likewise, I haven’t yet given DefCon DarkNet a try either — a real shame as the solder-your-own-badge nature of that challenge is right up my alley.

But finally, at the Hackaday SuperCon I finally got my feet wet with the crypto challenge created by [Voja Antonic]. He developed a secondary firmware which anyone could easily flash to their conference badge (it enumerates as a USB thumb drive so just copy it over). This turned it into a five-puzzle challenge meant to take two days to solve, and it worked perfectly.

If you were at the con and didn’t try it out, now’s the time (you won’t be the only one late to the game). But even if you weren’t there’s still fun to be had.

Thar’ be spoilers below. I won’t explicitly spill the answers, but I will be discussing how each puzzle is presented and the different methods people were using to finish the quest. Choose now if you want to continue or wait until you’ve solved the challenge on your own.

The Hacks And Puzzles Of The Hackaday SuperCon Badge

The greatest hardware conference is right around the corner. We would be remiss if the Hackaday SuperConference badge wasn’t the greatest electronic badge in history, and we think we have something special here. We’ve already taken a look at the hardware behind this year’s badge, and now it’s time to take a look at the challenges for this year’s Hackaday SuperCon.

The Puzzles

A conference badge isn’t good unless there are a few puzzles to solve, and the 2016 Hackaday SuperCon badge doesn’t come up short. Hidden behind an accelerometer-based gravity simulation, a moving message display, a Tetris clone, and an infrared communications protocol are a series of five challenges. The first SuperCon attendee to beat the challenge will be awarded a fantastic cash prize of $256 and win the respect of their peers.
