Let’s think of the last time you sent data without wires. We’re not talking WiFi here, but plain optical signals. Free-space optical communication, or FSO, is an interesting and easy way to transmit signals through light beams. Forget expensive lasers or commercial-grade equipment; this video by [W1VLF] offers a simple and cheap entry point for […]
At the risk of stating the obvious, building big things can be difficult. Sure, parts that fit on the bed of a 3D printer are easy to make, if not particularly fast, and scaling up from there is possible. But if you need a long beam or structural element, printing makes little sense; better to […]
Normal people throw away stuff when it breaks. But not people like us. Or, apparently, [NanoRobotGeek]. A cheap robotic dragonfly died, and he cannibalized it for robot parts. But he kept the gearbox hoping to build a new dragonfly and, using some brass rod, he did just that. The dragonfly’s circuitry uses a solar panel […]
A word of warning: Google for the definition of the word “pummer” at your own risk. Rest assured that this beautiful solar-powered circuit sculpture fits the only definition of pummer that we care to deal with. For the unfamiliar, a pummer is a device from the BEAM style of robotics, a sort of cyborg plant […]
