Resistor color codes are great, because they make it easy to identify a resistor’s value by referencing a simple chart (or memorizing that chart). But resistors are also very small and their color bands are hard for many of us to see clearly. Instead of buying a magnifying glass, J built the Great Resistor lamp […]
Revolutionary new technologies tend to require small, incremental developments. For example, physicist Julius Edgar Lilienfeld filed a patent for a transistor way back in 1925. But it wasn’t possible to actually build transistors until semiconductor production caught up in 1947 — something that took decades of “boring” materials research. Such research may seem trivial, but […]
Arduino Make Your UNO Kit is finally here The first Arduino UNO was launched back in 2005, with a clear purpose to allow everyone who had an idea to make it possible through a simple and open interface. Many years have passed, technology has evolved, but we never forgot that initial thrill that came from […]
As the frequency and intensity of droughts around the world continues to increase, being able to reduce our water usage is vital for maintaining already strained freshwater resources. And according to the EPA, leaving a faucet running, whether intentionally or by accident for just five minutes can consume over ten gallons of water. However, Naveen Kumar has […]
A beautiful, lush garden is a wonderful thing. Not only does it look good year-round and impress the neighbours, but it’s also a great place to spend time in the summer months and entertain guests. However, a good garden is not an easy thing to maintain. It takes many hours of hard work and toil […]
Long before Nicolas Cage ever portrayed the character on the silver screen, Ghost Rider appealed to an edgier subsect of Marvel’s audience. We won’t do a deep dive into the character(s) and their Faustian deals, but suffice it to say that Ghost Rider is a human man who turns into a flaming skeleton that rides […]
Some Halloween costumes are creepy, others are racy, and a few, like this one, are just plain cool. LEDs have been common since the 1960s, but they can still stand out when done well. As it turns out, one way to achieve that is by arranging 378 of them around a big globe and wearing […]
Inspired by a remote-controlled Radio Flyer tricycle in which Kermit pedaled around at Maker Faire New York 2018, Donald Bell wanted to create his own version that could bring similar magic to people who interact with it. It began with the same Radio Flyer tricycle as in the original video, except this one was modified a bit differently. An […]
You’re probably already familiar with the game Wordle — it was a hit in 2021 and then took the world by storm when The New York Times purchased it in 2022. The gameplay is simple to understand, but still challenging. Players have to identify a word through trial and error by making guesses to identify matching […]
The new Andor TV show, set in the Star Wars universe prior to the events of Rogue One, is already a hit and a big part of that is thanks to the B2EMO droid. Like many of the other droids in the Star Wars franchise, B2EMO manages to be very expressive despite being cold, hard steel. It conveys emotions and expressions through […]
