(Video, embedded below.) While some might take this as yet another sign of the end times, here it is simply a sign that the electromagnetic system […]
There are five general senses: touch for feels, taste for food, smell for avoiding trash, hearing for sounds, and, of course, eyesight for visualizing the very waves making up that sound. [PlasmatronX] drives that last point home with his camera for sound waves, that’s even able to capture constructive and destructive interference. (Video, embedded below.) […]
[Geeksmithing] and [When Geeks Craft] recently came together for a glowing collaboration. They wanted to build ever more attractive lanterns for a local parade event. They recently discovered a fantastic material that can really improve the look of whatever project you might be building with LEDs. The material is commonly referred to as “Black LED […]
Gaming is a wonderful thing. Unfortunately for many of us, work takes up our valuable time, which should be allocated to our gaming. What if there was a better way?
