Hah...that could easily have been MY backpack.
When I'm at DEFCON, I bring a fun little device. It's an ESP8266 that constantly listens for WiFi probes coming from people's mobile devices. It then displays the SSID (the network name) on a scrolling LED text display. I keep it plugged into one of those Anker battery banks. 10,000 mAh will power it for ~16 hours, so it lasts the entire day.
