WiFi Jumper
A matchbox-sized ESP8266 that hops from one open WiFi network to the next and phones home the network details and a GPS fix each time it gets online.

A wardriving rig with no laptop, no tether and no operator: an ESP8266 board that scans for unencrypted WiFi, connects to anything open, and — if that network has a route out — POSTs the SSID, BSSID and a GPS location back to a logging backend before disconnecting and moving on. It keeps a list of networks it has already used so it does not loop, and runs off a battery. AVR C/C++ for the ESP8266-12H, MIT licensed; the PHP/MySQL backend is left as an exercise. Hardware project, still at the breadboard-and-TODO-list stage.
