YouTube user Invisibules recreated Minsky and Shannon's "Most Useless Machine" (a box with a switch on it; switch it on and a hand emerges from the box and flips the switch to off) using Lego: 'The hardest part was probably getting the flap to operate easily and smoothly, and to open and close at the correct parts of the cycle.

The BBC reports on backers who pledged nearly $2m and are about to experience disappointment. Ash Hall, who reviews drones, published a damning video opinion piece on YouTube. He was fiercely critical not just of the […]
There are few things more satisfying than the clickety-clack of an old keyboard. So old, in fact, that it’s really more of a typewriter sound and feel than that of a keyboard. But if you want to enjoy the benefits of both, check out this Rymek Retro Bluetooth 3.0 Mechanical Keyboard. Bringing you an impressive […]
There are plenty of productive ways to spend time while stuck indoors. While it’s undoubtedly fun to binge all 15 seasons of Supernatural or sink days of playtime into an Overwatch campaign, learning something new is definitely a more meaningful and long-term beneficial use of open hours. And if you’re going to invest time in […]
If you’ve ever had any musical aspirations — or even if your talent extends no further than turning on the radio — you’ve probably dreamed the “impossible” dream. You dream that maybe you could record some of your songs at home, post them online, build an armada of fan support, attract major label attention and […]
