Hackster.io is hosting a BadgeLove meetup in San Francisco on Friday, October 18th:
Have you ever created a badge? Are you currently working on a badge? You are invited as a guest of honor to Hackster’s BadgeLove! Meetup. We want to take an evening to appreciate the hardware heroes who do the often thankless and frequently futile task of creating PCB artwork, shitty add-ons, and PCB badges.
Blinking electronic business card with NFC by Greg Steiert on Hackaday.io:
Reduce, Reuse, Recycle with this durable business card. Instead of filling landfills with dead trees, you can fill the bits in their contact folder by sharing your VCARD with a simple tap. The logo glows when the tag is read to acknowledge the transaction. There are also holes in the corners so that you can mount it, or wear it if you feel the need to join #badgelife.
This design uses the ST25DV04 to share contact information through NFC. It takes advantage of the energy harvesting function to light up the logo when the tag is read. The logo is lit by reverse mounted LEDs shining through the board from the back side.
The easiest way to configure the part is with one of the mobile apps provided by ST on their website. See the instructions for more details on configuration.
We are excited to announce this new contest with Hackster.io and Autodesk:

#BadgeLife is the new electronic graffiti. This form of art is in a league of its own, first popularized by DEFCON hackers, now boasts serious technical sophistication, a wicked artistic flair, peppered with political, cryptography, social, cultural and comical narratives, flashing LEDs and screens with add-ons galore.

Here is my brief overview of the badge on stage at the Summit:
OSH Park and Screaming Circuits produced an electronic conference badges for the 2018 Open Hardware Summit. Hardware design by Alex Camilo based on concept from ESP trINKet by Mike Rankin. Features for the OHS18 badge: ESP32 microcontroller with built-in WiFi; E-Paper to display the badge wearer’s name; badge wearer can update the displayed text from phone, tablet or laptops. Powered by 2x AA batteries.
This project was developed by a team of wonderful people that came together on Hackaday.io, in particular, this badge could not have happened without Alex Camilo and Michael Welling!
To use the interactive Python prompt (REPL), press the menu button on the badge and select Serial REPL from the Available Apps menu. The terminal emulator connected to the serial port should then display the interactive Python prompt (REPL). You can type in MicroPython code to experiment.
REPL stands for Read Evaluate Print Loop, and is the name given to the interactive MicroPython prompt that you can access on the ESP8266. Using the REPL is by far the easiest way to test out your code and run commands.
There is an USB-to-serial adapter board which be used to access the REPL on the badge via the serial port. However, a simpler option is to use the WebREPL:
Programming jig to flash 300 badges
Alex Camilo created this wonderful programming jig! Drew was able to use it to program all 300 badges and provision the names of the 150 people that pre-registered in time. Thanks so much to Artisan’s Asylum makerspace near Boston for giving us a space to work on the badges before the Summit!
Brian Benchoff writes on Hackaday:
The boards were made through OSH Park, and Screaming Circuits took care of the assembly. Anyone who has ever built a badge will tell you it isn’t the assembly that gets you — it’s the programming and provisioning. This is especially true since the Open Hardware Summit badge is distributed with the attendee’s names already preloaded. That’s a few hundred badges, all with unique firmware. This is a nightmare by any definition.
However, there’s always a good solution to a problem, and [Drew] from OSH Park showed me the best programming jig I’ve ever seen during the Summit pre-game at Artisan’s Asylum.
What you’re looking at is a 3D printed box loaded up with a touch-screen display, a Raspberry Pi Zero W, and a few pogo pins. This Raspberry Pi does all the heavy lifting by connecting to the Internet, pulling down the current version of the firmware, and loading that firmware onto the badge. There are a few more options thanks to the touch-screen interface, including provisioning all the badges with the names of the attendees — this can be done by reading a list of attendees and uploading the next one to the badge in the jig. All of this is wrapped up with a nice laser-cut cover that securely holds each badge exactly where it needs to be for the pogo pins to make contact.
This is, without question, the best programming jig I’ve seen. Any badge makers out there should take note: this is how you program a few hundred badges. The badge, itself, is great and just as this post is published there will be hundreds of eager hackers futzing about with this remarkable piece of hardware.

- Badges should have built-in USB port:
- USB connector makes it easy to multiple volunteers with laptops to flash firmware onto the badges in parallel, versus having just one programming jig
- USB connector makes it easier for people attending the Summit to experiment with modifying the firmware and developing their own functionality
- Pretend that the deadline is 1 month before the event
- We originally had the goal of being ready on September 1st for the September 27th conference, but we allowed ourselves to push the deadline for final firmware release to the day before the Summit. That meant staying up all night to flash the updated firmware on to the badges
- We should have identified the minimum feature set and simplified the functionality sooner in the design revision process
- We should have planned that we would have 3 hardware revisions and allowed for it in the schedule
Chicago game developers and hackers! Come on out to our first meeting at the DePaul University Idea Realization Lab. We’ll have a few short presentations from local developers on the platforms and controllers they’ve developed, followed by an open show-and-tell and gathering for people to talk about current, past, and future projects.
Short Presentations for our first meeting:
Rob Lockhart – Hi-5 Heroes, featured in GDC’s alt.ctrl (https://m.youtube.com/watch?v=fwRGkLwh_sk)
