WiFi Signals Vizualized

Luis Hernan uses long exposure photography and an instrument called a Kirlian Device. WiFi Signals Vizualized all around us are picturised using this technique. On his project website Digital Ethereal, Hernan explains:

The Kirlian Device is an instrument designed to reveal qualities of wireless networks. The device is named after Semyon Davidovich Kirlian, who discovered and perfected a photographic technique to capture electrical coronal discharges.

Inside, the device is powered by an Arduino UNO board connected to a Arduino WiFi Shield. Both components process and map the RSSI values of a previously specified SSID network into colour using a heatmap colour scheme. The mapped colours are then passed to a Pololu LED strip. The operation is possible by the use of two 5V lithium batteries.
