Man Maps Home Wi-Fi Signal in 3D
Ashley Allen / 2 years ago
YouTuber CNLohr has developed a low-tech device for creating a 3D map of a Wi-Fi network signal, and has posted the firmware and software he used to GitHub.
CNLohr used a battery-powered ESP8266 chip that he moved around his house to track his Wi-Fi signal strength. The Device has an LED attached that changes colour depending on the quality of the signal. All the data collected was then used to create a 3D model, showing all the hotspots and blackspots around his home.
