We are designing a badge to help our visitors and volunteers navigate the camp. It will feature an e-paper display for visibility in bright daylight, as well as a powerful ESP32 module for wireless development.
Why make a badge?
We would like to distribute badges to every SHA visitor for 2 main reasons
Augment the event
Name badges are nice, but a display can do much more than static text. With the onboard Wi-Fi and Bluetooth connectivity we can deliver for example weather information and timetables right to visitors. And what if you could have live subtitles of the talk that you are watching around your neck?
Be a development platform
As most hackers like ourselves like to tinker with hardware and software, the badge will be an open platform to experiment on. All the basics for a great development platform are on board, including handy inputs and outputs. We designed the badge to be accessible, and easily programmable by MicroPython in an online environment. We strive to use new and cutting-edge hardware on the badge to demo modern IC's and modules.
What is on the badge
First and foremost, the badge will have a 2.9" e-paper display (296x128pixels). This is a 1-bit monochrome display which supports partial refresh, and with some firmware hacking we are able to emulate a larger bit depth and increase its responsiveness.
Footprints for six SK6812 or pin-compatible addressable LEDs are placed above the display. These were chosen to match the official SHA2017 design, which includes a freedom flag consisting of six RGB colours based on the SHA1 hash of some text or data. Using the ESP32's hardware SHA1 unit we may be able to display the colours corresponding to for example the name on the badge.
Any interactive badge needs input. To keep the badge a single-sided load for production, we opted for eight touch buttons (up, down, left, right, a, b, start, and select). The battery will be decently sized, and should be able to last for at least a day when used interactively. The battery life will of course be better when only used as a badge, thanks to the e-paper display :)
How far is the badge?
The hardware design is nearly finished, and we are very satisfied with it.
SHA is dedicating its income towards organising an awesome event. Of course the badge is part of that, but its parts and manufacturing cannot be covered by the ticket sales. Nearly everything will need to come from generous sponsors, and we still need a lot of those.
I want to help your badge!
Awesome! Please contact Team badge! We are currently in need of your help! Parts or funds in any way would help us a lot.
What can you offer in return?
We can display your logo on the badge's screen, as well as the SHA2017 website. Of course, you will receive a thankful mention in our presentation during SHA2017.
We need your support in building the badge. In return, we are offering a spot for your logo on the website, the info booklet, lanyard and on the badge itself. Additionally, we would like to challenge you to write an awesome app for the badge to interact with our visitors.
There are two main routes to sponsorship which will be particularly helpful:
- Goods and services
We need a number of electronic components as well as PCB manufacture and assembly. If you have facilities to supply such goods and services, or if you have preferential pricing with your suppliers, this is the most efficient route.
- Cash donation via invoice
Your sponsorship would be tied to specific goods and services, but we would source them directly and provide you with an invoice. This is the simplest route.
Would you like to support the badge?
Please send us a message through firstname.lastname@example.org or call +31 85 888 3001.
Always wanted to sponsor a component? Want to be part of this amazing badge? Now is your chance! Whatever your budget, we will be able to handle your crowdfunding craves! In return we promise to send you extra love and sign your badge during the event!
Crowd-funded donations can be transferred to NL88BUNQ2290596736, account holder "SHA2017 BADGE". Please put your name in the description so we can thank you appropriately.
We would like to thank the following crowd-funders for their generous donations:
- Sebastius (SHA2017 Orga)
- Boekenwuurm (SHA2017 Orga)
- initfour websolutions
- mr_seeker (SHA2017 PL)
- Anne Jan Brouwer
- R. Labudda

We've begun gathering and writing the documentation you'll need to get started on the Badge. It's an immense project, like the badge itself.
Here is where you find the docs!
