Always wanted to look at the electro-magnetic soup of signals sloshing around you. Tuomas made a device that let’s you watch these signals on your scope. It consists of an inductor that picks up the signals, and an amplifier that well amplifies them so you could watch them on your scope. Check out a video of Tuomas testing various equipment with his new toy below.
There’s something fascinating about electromagnetic fields. Thanks to the modern world and the prevalence of electronics and electricity, they’re all around us these days. But because of the extremely limited array of senses that we humans have, we spend most of the time completely oblivious of them. Wouldn’t it be cool to make something simple that could not just detect them, but would allow you look at the waveforms on an oscilloscope. An EMF probe in other words.
