An extremely common project for a control systems class is the inverted pendulum. Basically, it’s a robot mounted on a linear rail, a hinge, and a pendulum sticking straight up in the air. Get your algorithms right, and you have a pendulum that seemingly resists the inexorable pull of gravity and a great understanding of how Segways, balancing robots, and quadcopters work.
[zakowy] is taking this to the next level with his entry to The Hackaday Prize. It’s an inverted pendulum with two counter-rotating propellers in a gimballed fan, and the most unstable UAV design we’ve ever seen
There is a specter haunting America — the specter of the pumpkin spice latte, henceforth referred to as the PSL.
It’s like The Walking Dead up in here, but instead of zombies, every other person, bros and basics alike, is a Starbucks PSL drone. You can’t wear so much as a flannel scarf out of the house without fending off wild-eyed PSL lovers raving about the onset of autumn and the arrival of PSL season.
We used to call it football season, people. This used to be football season
If morning television is a particularly dense portrait of a culture, then the TV we watched before the planes struck, with its cheery anchors and shots of a beautiful fall morning, look like a time capsule from another era, another country even. In 2011, Motherboard’s video producer Chris O’Coin and I dipped into the Internet Archive and scanned through hours of footage from the far side of the 9/11 attacks. We weren’t interested so much in how the various networks covered the breaking story; there is seemingly no end to the early news footage that began around 8:46 in Lower Manhattan, first on CNN, then on NBC, and then on every news channel from Beijing to Baghdad.Instead, we had hoped to grasp a sense of how things felt back then, in that last hour before nothing would be quite the same again. What we found was stranger and more disorienting than we could have anticipated
A drone model from DJI comes with a camera, GPS positioning and other features meant for producing high-quality still images and video.
By far one of the craziest entries for The Hackaday Prize is [Peter McCloud]‘s Goliath, an enormous gas-powered quadcopter. It weighs about 240 pounds, is powered by a 30 horsepower v-twin lawnmower engine, is lifted into the air with homemade props milled on a CNC machine. It’s a frightening build even when the engine isn’t turning. When running, it’s an awesome display of power and technology.
Goliath has had a few setbacks of late, snapping two composite props in its first attempt at hovering
