Forget science t-shirts and obscure math formula tattoos; there is now a more fashionable way to get your geek on. Upcycling old circuit boards, the folks at Circuit Breaker Labs handcraft unique pieces of jewelry that show the miniature beauty of a PCB. If you ever take the time to look closely at a circuit board, you might notice that the mass of electrical parts, in addition to running your devices, looks like a digitized miniature city. The conductive tracks resemble roads, while the capacitors, resistors, and other soldered components serve as the city’s structures. This imagination and sense of creativity are what Amanda Preske wants to bring out in her…

As someone in my early thirties, my knowledge of the money-making process is as follows: you go to work, get paid, end of the story. I have yet to wade through the vast ocean that is the stock market. I heard it’s also a good way of making money, provided you know which companies to invest in. It never hurts to get an early start on this stock market thing. But with so many numbers to look out for, it seems like a daunting task to keep afloat in it. So, is there any way to at least ensure your success here? https://www.youtube.com/watch?v=RlNv1kYmQas&ab_channel=TickrMeter The TickrMeter is a piece of equipment…

You might have seen a gun equipped with a silencer in your favorite movie, show, or video game before. With a long, metal tube attached to the barrel of a firearm, you would hear the iconic *tfft* of muted bullets as they whiz towards their targets. But fiction is rarely anything like real life, and silencers cannot completely eliminate the sound of a gunshot emanating from a gun. There’s a lot of sciencey stuff behind it but to make things more digestible, gun silencers create a chamber for high-pressure gas to dissipate. Firing a gun requires gunpowder, and the air pressure generated from firing a bullet is massive (around 3,000…

When Apple released its object-finding AirTags back in April, it probably expected us to snap them on some expensive belongings. You know: wallets, keys, those sorts of things. I mean, you’re paying $29 for a single AirTag; might as well keep it on something valuable. But in the case of Matty Benedetto, creator and product designer at Unnecessary Inventions, his prized possession just happens to be a pair of very white and suspiciously new-looking socks. https://www.youtube.com/watch?v=EUtxrXc7dX4&ab_channel=UnnecessaryInventions I’m not one to judge but there are two glaring issues when it comes to sticking AirTags onto socks. One: socks are usually made of thin fabrics and there is no natural way they…

Owning a pet means a boatload of responsibilities. This is why getting a short break from all those tasks (or at least making them easier to manage) feels like a huge relief. We already saw it with the auto-filling litterbox on Kickstarter. Nonetheless, our pet’s doo-doo isn’t the only thing we need to mind when we’re not at home. They need to drink, too! Well, this is where Drinkie comes into action. https://www.youtube.com/watch?v=vMdPIyRuC00&ab_channel=DrinkiebyCheerble Drinkie is an automated drinker that streamlines the grueling, arduous tasks of constantly filling and cleaning your pet’s drinking bowl. Instead of refilling a normal bowl multiple times a day, Drinkie will just require you to do…

You might not notice it because of how fast it leaves your hands, but paper bills have some neat tricks up their sleeves. Everyone knows about serial numbers and security ribbons, but did you know certain national banknotes (US Dollars included) have a layer of invisible ink that makes them even harder to counterfeit? That’s right! Just pop a dollar bill under a UV light and watch parts of it glow! Some banknotes have invisible ink designs which are flashier than others. The 100 Brazilian Real note, for example, has a numeric “100” printed on its left-hand side. Another one is the 5,000 Hungarian Forint note that has a very…
