What does Wi-Fi look like?

Why guess where the source of the Wi-Fi signal is located, if one can see its location in color? The scientist-programmer has found a way of constructing colored 3d-cards, displaying the strength of the Wi-Fi signal. All that is needed is a color LED flashlight, a laptop and a coordinate machine.

Dominic Taibout, a professor at Smith College, ran into this discovery when he secured the LED-LED to a battery and a computer chip designed to measure the power of Wi-Fi. Taking the resulting gizmo in his hands, the professor moved from room to room, and at each point the chip sent data to the laptop about the quality of the Wi-Fi signal, as well as the color corresponding to it. Red zones are marked with weak signal zones, blue and green show high-quality Wi-Fi.

The researcher drew attention to the fact that when moving, the colors change strongly, even at adjacent points, which are close to each other. Then he took the trajectory of his movement and signal strength onto the digital camera, and found a huge number of places for poor reception of Wi-Fi.

After that, Taibout attached his installation to the tooth of a woodworking coordinate machine capable of moving in three dimensions (with the help of such an installation it is possible to create intricate bends, getting the most incredible psychedelic products). As the machine moved, the attached sensor with color coding moved around the room, drawing a map with the appropriate signal level.
