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.
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).
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!
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.
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.
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).
