2015 was the year of the unofficial hardware badge at DEF CON 23. There were a ton of different hardware badges designed for the love of custom electronics and I tried to catch up with the designer of each different badge. Here is the collection of images, video demos, and build details for each one I saw this weekend.
Gorgeous text treatment on back of this badge is indicative of [True’s] mastery
[TrueControl] did a great job with his badge design this year for the Whiskey Pirate Crew. This is a great update from the badge he designed last year, keeping the skull and bones outline. It uses a PSOC4 chip to control a ton of LEDs. The eyes are RGB pixels which are each on their own PCB that is soldered onto the back of the badge, with openings for the LED to show through. Two AA batteries power the board which has a surface-mount LED matrix. The user controls are all capacitive touch. There is a spinner around one eye, and pads for select and back. The NRF24L01 radio operates at 2.4GHz. This badge is slave to commands from last year’s badge. When the two are in the same area the 2015 badges will scroll the nickname of the 2014 badge it “sees”. The piezo element also chirps many different sounds based on the interactions with different badges.
[True] makes design an art form. The matte black solder mask looks fantastic, and he took great care in use of font, size, alignment, and things like letting copper show through for a really stunning piece of hardware art.

DEFCON is huge. Last year attendance tipped at about 16k, and we’d wager this year will be even bigger. [Brian] and I will both be among those attending (more on that below) but I wanted to take this time to show you the right way to do a Hacker Conference.
Build Your Own Badge
We met a ton of people at DEFCON 22 last year, but the Whiskey Pirates made a lasting impression. I first ran across two of their crew walking the hallways of the con with this awesome badge. How can you not stop and strike up a conversation about that? Turns out this group of friends have been meeting up here for years. This year they went all out, designing one badge to rule them all. And like any good hacker project, they weren’t able to finish it before getting to the hotel.
Set Up Your Electronics Lab
Binoc microscope for rework
This badge’s LEDs changed to purple
Rack of equipment
Hot air and more
So, you didn’t stuff your boards before leaving home? For the Whiskey Pirates this is not even remotely a problem. They just brought the electronics lab to their suite in the Rio Hotel.
On the bathroom vanity you find the binocular microscope which was good for troubleshooting an LED swap on the official conference badge. An entire cart with hot-air, multiple solder stations, oscilloscopes, and more was on hand. I populated the surface mount LEDs on the badge the crew gave to me. When I was having trouble seeing my work they called the front desk for an additional lamp. You should have seen the look on the bellhop’s face when he walked in!
A bit of marathon assembly and everyone from the Whiskey Pirates (plus me) had a working badge, demonstrated in the video below. But this isn’t where the fun stops.
