E-Paper Badge is a Hint at Great Things to Come
Friend of Hackaday, Drew Fustini, came to our Breakfast at DEF CON meetup sporting a name badge of his own design. The E-Paper Badge uses a Teensy LC to drive a 2.15″ E-Paper display. The row of capacitive touch buttons to the left allow the image to be changed, and he just happened to have the Jolly Wrencher in the gallery of choices for this picture.
This badge gets me really excited for this year’s Open Hardware Summit which is at MIT on September 27th. This year’s badge is a collaborative effort between a group on Hackaday.io! It’s basically Drew’s badge on steroids, and he told me the experience of working with a team has been really positive. It seems each time the group hits a hard problem or a pile of work that needs to be done, someone on the team grabs it and runs with it. It’s a great example of both certified open hardware and team development.
I tried my best to see every badge and speak with every badge maker at DEF CON 26. One thing’s for sure, seeing them all was absolutely impossible this year, but I came close. Check out the great badges shown off in volume 1 and in volume 2 of this series. The game is afoot…
Last week, tens of thousands of people headed home from Vegas, fresh out of this year’s DEF CON. This was a great year for DEF CON, especially when it comes to hardware. This was the year independent badges took over, thanks to a small community of people dedicated to creating small-run hardware, puzzles, and PCB art for thousands of conference-goers. This is badgelife, a demoscene of hardware, and this is just the beginning. It’s only going to get bigger from here on out.
We were lucky enough to sit down with a few of the creators behind the badges of this year’s DEF CON and the interviews were fantastic. Right here is a lesson on electronic design, manufacturing, and logistics. If you’ve ever wanted to be an engineer that ships a product instead of a lowly maker that ships a product, this is the greatest classroom in the world.
Although badgelife may seem like a bunch of hardware engineers sitting behind a pick and place machine for a weekend’s worth of lulz, this is a masterclass of product design and manufacturing. Badgelife is product development, and unlike many other hardware design jobs, the ship date will not slip for any reason. The hardware must be done on time, and if you’re not shipping all the features you promised everyone will be upset. Badgelife is the best experience you’ll ever get in engineering for production, product design, and manufacturing.
Meanwhile at Ctrl-H PDX hackerspace:
Anyone in the hackerspace lately may have noticed our @DC503 #badgelife projects taking shape. If you’re headed to @defcon and want to get your hands on this one, or get one of these around your hands, check out http://503.party . See you in Vegas!
OSH Park is producing electronic conference badges for the 2018 Open Hardware Summit. The hardware has been designed Alex Camilo, based on concepts from the ESP trINKet by Mike Rankin. The badge features an ESP32 microcontroller and a 2.13″ E-Paper display.
OSH Park shared project for the Rev 3 by Alex Camilo :
We expect this to be the final revision.
It is ordered on Super Swift today and should be validated next weekend. This will allow us to order the full quantity PCB panels in August 13th. Assembly is estimated to be 10 business days from the day when all components and PCBs are received.
Rev 2 photos:
And for those interested, here is a link to a gallery:
Terminal output on Rev 2 prototypes:
The Rev 2 prototypes have NodeMCU boards soldered on to the back to serve as a USB to serial adapter.
One of the Rev 2 prototype boards that Alex sent me has the default e-paper demo:
The other has MicroPython installed! 🙂

We’re still coming off the Hackaday Belgrade conference right now. If you were there, you know it was the greatest hardware conference ever. If you weren’t there, you missed out. Sorry. (Make sure you get in on the Hackaday Superconference in November.)
One of the many highlights of the Belgrade conference was, of course, the badge. The 2018 Hackaday Belgrade Badge is a masterpiece of hardware with a 55-key keyboard, RGB TFT LED, speaker, and a BASIC interpreter.
This badge is a masterpiece of electronic design by Voja Antonic. Just to take one small example from the design, check out the placement of the buttons. Think the slightly rotated buttons that make up the keyboard is only a stylistic choice? It’s not; by carefully rotating each button, the legs of each switch can fit in between each other. It’s brilliant.
