Michael created a dog-shirt equipped with persistence-of-vision LEDs controlled by a LilyPad soft Arduino, and programmed it to output the text of my novel Makers as his pooch ran gleefully around the park at night. Then he photographed it and sent it to me, and my head exploded with delight.
Mounting 5 LEDs on a moving object creates one of the cheapest and largest displays: Persistence of Vision. It's been done on bicycle wheels, fans and other rotating objects.
In this project i am sewing a Lilypad wearable Arduino board and five LEDs with conductive thread on my dog's shirt. She's a Miniature Pinscher running very fast for fun. In curves fast enough for Persitence of Vision. And she likes running in large circles in the park! Light writing.
In this footage, a supercomputer’s CPU cores — nearly 900 of them — are neatly lined up in the Task Manager. The Doom logo appears, generated by code that targets each core. Then Doom itself plays, each “pixel” generated by thrashing a core with just the right amount of busy work. Max Holt: Finally got […]
The UK government today ordered domestic companies to stop buying equipment from Chinese vendor Huawei and to stop using its kit entirely by 2027. Huawei is suspected to be an arm of the Chinese government, breaking into western markets (and maybe its networks) by selling impossibly cheap equipment. The UK only recently approved more Huawei […]
Every company needs to have a firm grasp on their bottom line. But while every company used to have their official ledger books or one of those old-school physical world accountings of a company’s every asset and expenditure, many firms don’t work that way anymore. Oh, they all still balance their “books” (if they want […]
For all its downsides, you have to admit all this extra time spent at home has to have boosted your creativity. More time to sit and think means more time to develop new original ideas. Trust us, you wouldn’t be the first to find that a global emergency has fueled the need to start a […]
Back in the old days of the 20th century, practicality was the biggest reason most people wore a watch. If you didn’t have a clock face right on your wrist, how else would you know the time? Of course, in the age of smartphones and even smartwatches, the time is available virtually everywhere at any […]
