Light Painting Photos That Give a Visual Look at Wi-Fi Signals

Here’s one of the most creative examples of light painting and long-exposure photography we’ve seen — a few techie guys built a special 12-foot-long rod with 80 LED lights that light up depending on how strong a particular Wi-Fi signal is. By walking the stick around and capturing the lights in real time, they were able to photograph “light charts” showing how a particular Wi-Fi signal strength fluctuates in a particular area.

    Here is a similar story

    This project explores the invisible terrain of WiFi networks in urban spaces by light painting signal strength in long-exposure photographs. A four-metre tall measuring rod with 80 points of light reveals cross-sections through WiFi networks using a photographic technique called light-painting.

    Unfortunately, location isn’t the only variable here… time is at least as significant.

    Very nice video, I like the concept as it’s unique and innovative. Yet indeed time is very significant here
