This truly wireless desktop PC build will blow your mind

In a nutshell: It's not every day that you stumble across technology that truly impresses, but today might be an exception. In short, popular YouTube channel DIY Perks has demonstrated a truly wireless power delivery system capable of powering an array of devices using an "invisible dome of energy" at an impressive distance. To grasp the wizardry at play, it helps to have a general understanding of how wireless phone charging mats work. As the presenter explains, such chargers use a coil of wire to generate a magnetic field that flips in polarity thousands of times per second. Place a second wire coil in close proximity, and the continually changing magnetic field will create an electric current in the second coil – hence, wireless power delivery. The problem with conventional wireless charging pads is that the two coils need to be in close proximity to each other, and near-perfect alignment is also key. The system DIY Perks built, however, doesn't have these limitations. Its workin ... Read full article.
