AND!XOR’s DEF CON 29 Electronic Badge is an Assembly Puzzle

Hackday editor Mike Szczys reviews the latest #badgelife masterpiece from AND!XOR:

For years I’ve looked forward to seeing each new unofficial hardware badge that comes out of the #Badgelife powerhouse known as AND!XOR. A mix of new and interesting components, alternate-reality game, and memes, you never know what they’re going to throw down.

A bubble pack landed on my desk on Thursday with the newest offering, the AND!XOR electronic badge built for DEF CON 29, happening this weekend as a hybrid in-person and online conference. While each previous year upped the ante on complexity and manufacturing magic tricks, it’s no surprise considering the uncertainty of both the global pandemic and global chip shortage that they took a different tack. What we have here is a badge hacking puzzle that challenges you to just figure out how to put the thing together!

The boards themselves are obviously the “After Dark” treatment of OSH Park (and sure enough, their logo is on the back of the board). The iconic treatment uses black substrate (the board itself), clear solder mask to let the copper traces show through, ENIG plating for golden pads, and white solder mask.

Fairy Dust mini PCB pin for RC3

We are excited to see the wonderful Thomas Flummer in Copenhagen has designed a neat PCB pin for the virtual Chaos Communication Congress next month:

Fairy Dust mini PCB pin for RC3

This is a small PCB pin badge, heavily inspired by the RC3 styleguide. It’s designed to be small, easy to assemble and hopefully many will manage to get some before the event, and be able to share a little bit of physical #badgelife, in this time of virtual events.

Making your own

If you want to make your own, I have included the gerbers, in case you don’t want to install the nightly version of KiCad.

There is also a shared projects at OSHPark, and this is designed for the standard purple PCBs. It’s designed to be exactly 2 square inches, so for USD 10 you get 3 pcs. shipped anywhere, though the standard shipping might take a bit to arrive.

The parts needed for this pin is simply 4 white 0603 LEDs, a series resistor, also 0603, to limit the current a bit (I’ll try with a 1K to begin with), a CR1220 coin cell holder (I’m planning on using a Q&J CR1220-2 from LCSC) and then a little round brooch clasp/tie tack pin (I got some on ebay, but a DIY/craft supply store might also have them).

Please share

If you decide to make this badge or a variant of it, please share images so we can all see it and get inspired. If sharing on social media, please use the #badgelife tag and please let me know, I would love to see what you have made!

Hackaday Remoticon: learn to solder surface mount in style!

The annual Hackaday Supercon is taking place as Remoticon this year on November 6th to 8th. The talented Thomas Flummer has design a PCB badge based on the SMD challenge that can be further customized in KiCad.

There is still time before November 6th to order the board from the shared project page in “After Dark”:

Mask up with OSHCat 2020

TwinkleTwinkie creates amazing PCB artwork. One project we have loved is the OSHCat which first debuted as a badge-on in 2018:

And the follow-up last year:

While there was no Defcon in Las Vegas this year, OSHCat has returned as an example of how to keep humans safe during the pandemic:

The design is available as a shared project:

Experimenting PCB rendering using KiCad, FreeCAD and Blender

Anool from Wyolum has published an exciting blog post about 3D renders:

Experimenting PCB rendering using KiCad, FreeCAD and Blender

I’ve been putting off using Blender since over 5 years, being intimidated by the complex UI and workflow, until this month when I mustered courage to go through Andrew Price’s Doughnut tutorials. My aim was to learn how to do photo-realistic renders of KiCad boards.

Flux Capacitor badge add-on

BTTF

We really like this “Back to the Future”-themed Flux Capacitor badge add-on (SAO) by Squaro Engineering made with our “After Dark” service (which features clear soldermask on black fiberglass substrate).

Trash Dove Badge by Angela Sheehan

Angela Sheehan has made a beautiful LED badge based on Syd Weiler’s Trash Dove sticker:

Trash Dove Badge

An LED badge I created as a Valentine gift for my partner. The artwork is a rendering of a sticker we often send each other in conversation on messenger.
I had fun using this project as a way to gain more practice in AutoDesk EAGLE.

The first thing I did was draw a simplified rendering of the artwork in Illustrator with a condensed palette. The original artwork uses a few different shades of color.

Luckily, OSHPark’s signature purple solder mask, ENIG, and white silk were already pretty good matches for the original sticker palette, so I just needed to make a few adjustments.

I decided on three tones of purple created by:

  • Mask over FR4 for the back bird (darkest purple)
  • Mask over copper for the front bird’s wing and head (lightest purple)
  • Mask over copper stripes for the front bird’s body (mid purple)

I used silk to define some details and for the back bird’s head, and exposed copper for the orange yellow parts of the original artwork.

The heart I left open to backlight with a red LED.
