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.
