We’re probably all familiar with adding wood dust, hemp and carbon fibers to PLA filament, but there are so many other fillers one could add. During the completely unrelated recent heatwave in Germany, [Stefan] from CNCKitchen decided to give a new type of biodegradable filler type a shot by scooping some freshly dried cow patties […]
There was a time when all the cool kids had a 45 RPM record player. [RF Burns] picked up a 1950s-era player from RCA. However, it needed a lot of work. The good news? We get to see the teardown and the result in a two-part video series, which you can see below. If you […]
If you are looking for the perfect instrument to start a biological horror show in our age of AI, you have come to the right place. Researchers at Johns Hopkins University have successfully used AI-guided robotics to perform surgical procedures. So maybe a bit less dystopian, but the possibilities are endless. Pig parts are used […]
A man named [Jim Valvano] once said “There are 86,400 seconds in a day. It’s up to you to decide what to do with them.” — while we couldn’t tell you who [Jim Valvano] was without a google search*, his math checks out. The quote was sufficiently inspirational to inspire [danjovic] to create a clock […]
There’s something ominous about robots taking over jobs that humans are suited to do. Maybe you don’t want a job turning a wrench or pushing a broom, but someone does. But then there are the jobs no one wants to do or physically can’t do. Robots fighting fires, disarming bombs, or cleaning up nuclear reactors […]
It is virtually a rite of passage for C programmers to realize that they can write their own cooperative multitasking system. C is low-level enough, and there are several ways to approach the problem, so, like Jedi light sabers, each one is a little bit different. [Christoph Wolcher] took his turn, and not only is […]
It’s an unfortunate fact that when a scientist at MIT describes an exciting new piece of hardware as “low-cost,” it might not mean the same thing as if a hobbyist had said it. [Caden Kraft] encountered this disparity when he was building a SCARA arm and needed good actuators. An actuator like those on MIT’s […]
Sure, Apple’s Lisa wasn’t the first computer released with a graphical user interface — Xerox was years ahead with the Alto and the Star workstation — but Lisa was the first that came within the reach of mere mortals. Which doesn’t mean many mortals got their hands on one; with only about 10,000 sold, they […]
You are probably familiar with initiatives like Seti@Home, where you donate unused computer power to some science project that needs computer cycles. [Jeff Yoshimi] wants to borrow your most powerful computer: your brain. The reason: cancer research. [Jeff’s] recent book, Gaming Cancer, has three examples: Eterna, Foldit, and Nanocrafter. All three make games out of creating […]
