Invisible Networks

Three Norwegian guys decided to show radio waves, taking for example the WiFi network.
Using photographic equipment called “Freezelight”, the authors of the project tried to depict the power of the Wi-Fi signal, which is impossible to see in person.



The technique of obtaining such photographs is quite simple: one person walks around the city with a four-meter mast, in which a microcontroller, a WiFi receiver and 80 light bulbs are embedded. Another person records this process with a camera, with a long exposure, thanks to which the man himself with the mast in the frame will not have time to light up, and only a trace of light bulbs remains:

By the way, Richard Feynman, already explained to his viewers the amazing properties of the waves, and of course he did this very figuratively and vividly, drawing in his mind the rather informative pictures that allow him to better understand how this world works.



However, one thing to describe in words, and quite another - to show live. And thanks to the guys for portraying this on video.
