Badges unveiled

A project that’s been going on at W88 for the past four or five months went public yesterday. We’ve been designing, prototyping and programming a PC board to be used as a conference badge at Thotcon 0×4, Chicago’s hacking conference. Yesterday around seven hundred badges were passed out to conference attendees, each badge having an Atmel processor, LED array, and 2.4 GHz transceiver. The badges were able to process location checkins from beacons throughout the room, display messages from the organizers, and report their own id to the network. Since the board includes the Atmel ATMega128RFA1 processor and an Arduino compatible form factor, the badges can be reused for many Arduino projects.
This was a big project for us, requiring a lot of late nights and a lot of learning. For the team, It’s the first W88 production board, the first experience with 2.4GHz networking, first double sided prototype, first time using a QFN processor package (with luck, also the last), first reflow rework experience – though we thought it could be done, there were many challenges. Not only did we get it done on time within planned cost, we had a lot of fun doing it.
