Software is coming along. The major building blocks have been written:

Still need to move the RFM69 code out of its test harness and into the main code. Of course to start testing this we will need to assemble another breadboarded badge to pass data back and forth.

One of my complaints with electronic badges has been management of firmware. It's inevitable that bugs will be discovered when your userbase goes from 1 to 5 to 500. It seems that every group is re-flashing badges with fixed software at the con and I have yet to see one with an indicator of the software version inside. We've added this to the badge. As of today we're tagging the software as v0.5.0. Hopefully this will reduce confusion should any firmware pushes be necessary at DEFCON.
