How to: Wifi Signal Strength Light Painting
Wireless networks are everywhere these days, creating invisible layers that we cannot see. This unique light painting project seeks to change that by mapping the signal strength of Wifi networks in a variety of environments. The light painting is made using a WIFI signal strength detector and a bar of LED lights. They used a long exposure camera to capture the fluctuations in signal strength as they walked across a street, campus, etc.
The light painting is not about visual beauty alone; the project documentation shows full details on the electronics used during the build process.
