Mark Rober is bad at darts, but he still gets perfect scores, because he's good at engineering.
I fulfilled a 3 year long dream to create a dartboard where you get a bullseye every time thanks to some engineering. Basically, you throw a dart and then a Vicon motion capture system tracks the dart in the air. We use those x,y,z positions in matlab to predict where the dart will land using some regression analysis. Once we know where it will land, we move the board to the right spot using 6 stepper motors that attach to the back of the board using fishing line. All of this happens in 400ms or so. Then we took it to a bar to see what people would think of it
Université de Sherbrooke engineers demonstrated a wearable robotic third arm that weighs about the same as a human arm. According to Evan Ackerman writing in IEEE Spectrum, waist-worn hydraulic limb “is gentle enough to pick fruit but powerful enough to punch through a wall.” From his interview with project lead Catherine Véronneau: IEEE Spectrum: Can […]
The best solutions are sometimes the simplest ones: “I’ve been topping off a leaky tire for weeks and staring at my garden hose wondering if I could use it instead of my compressor. The answer is YES!!!”
Maybe after four months, you’re finally getting tired of staring at that less-than-brilliant home computer monitor. Or maybe you really need to create your own dual-monitor configuration in your home office like the one back on your desk at work. Or maybe that 15-inch screen just isn’t doing it for you anymore and you need […]
Unlike the unquestioned effectiveness of a solid strip of duct tape, you never quite know what you’re going to get when you try to repair something with glue, do you? Whether it’s the material itself that you’re gluing or how much glue you apply or how long you let it sit before testing, there’s always […]
Now that we’re past July 4th, we’re truly turning smack into the sharpened teeth of the summer heatwave season. As temperatures and humidity spike, it just makes all the rest of the nation’s current problems that just tiniest bit more irritating, doesn’t it? Hey, we’re all in this together. So if we can help chill […]
