NodeConf EU Hackable Badge

During conferences, a name-tag is one of the first things people look at when bumping in to others – mentally trying to keep track of faces and names. But gone are the days when your name tag was a post-it stuck on your arm. Over the years, conference badges have become increasingly interesting and complex. Hackable electronic badges are becoming the norm, and not just at hardware cons. For the recently concluded NodeConfEU conference in Ireland, [Gordon Williams], of Espruino fame, designed a JavaScript centric hackable badge.

NodeConf EU is the key Node.js event in Europe, providing a forum for the Node.js community. So when they brain-stormed ideas for a conference badge, they obviously gravitated towards a design that could run JS. [Gordon]’s Puck.js fit the requirements perfectly, and he was tasked with creating a new design based on the Puck.js. The feature list included BlueTooth Low Energy, low power consumption so it could run off a CR2032 battery, a high contrast LCD, some buttons, NFC, and a prototyping area – all packaged in a beautiful hexagonal shaped PCB (obviously) to resemble the Node.js logo. The badges were programmed with attendee names, but the fun, juicy part could be accessed by pressing buttons in the Konami code sequence.

Easy to follow, detailed documentation helped hackers quickly get started with code examples. They were also presented several challenges to work through allowing them to get familiar with the badge. Hacked badges were entered for a Grand Challenge with a chance to win a free ticket to next years conference. The badge hardware and firmware are open source and source files are hosted in a Github repository. Check out a short overview of the badge in the video after the break.

Thanks to [Conor] from nearForm for letting us know about this awesome badge.
