The Next HOPE Geiger Counter

Six of us went to HOPE this year. What a time we had. Very little sleep, lots of socializing, and even some hacking. Nathan made me bring our Wifi Geiger Counter to work on and show off. This turned into more of a hacking project than a fixing project. This years conference badge features an MSP430 and a Nordic nRF24L01+ radio. They could communicate with each other and a tracking network. After realizing the badges could be aware of other badges I came up with a plan! Now the Geiger Counter detects other HOPE badges!
