Mapping WiFi Signals in 3 Dimensions

[Charles] is on a quest to complete ever more jaw-dropping hacks with the popular low-cost ESP8266 WiFi modules. This week’s project is plotting WiFi received signal strength in 3D space. While the ESP8266 is capable of providing a Received Signal Strength Indication (RSSI), [Charles] didn’t directly use it. He wrote a simple C program on […]

[Martin] decided that using the ESP8266 with an external microcontroller was overkill, and decided to implement his project entirely on the module with a built-in web server. [Martin] started out with the ESP8266 web server firmware developed […]
