Introduction Hi guys, today we will be focusing on displaying mini graphics and texts on an 8×8 LED matrix using the MAX7219 (or MAX7221) LED driver and the Arduino Uno. The 8×8 LED matrix displays are usually used for the display of symbols, simple graphics and texts. Made of super bright LEDs, they produce low […]

Back in 2007 Apple released the first generation of iPhone which is considered as the first smartphone as those we use today. Before that, PDAs (Personal Digital Assistants) dominated the market and some even included network connectivity, the ability to send and receive calls, and password unlocking. The iPhone inherited the ability to be unlocked

Researchers led by Kourosh Kalantar-Zadeh, at RMIT University in Melbourne, Australia have developed the first intestinal gas-diagnosing pill to be tested in human. During the study, which was published on January 8 in Nature Electronics, the swallowable gas sensors were tested in seven healthy participants who ate low and high-fiber diets. This ‘smart’ capsule is capable of measuring levels of Oxygen,
Sorting candy by color is a classic problem that has its roots in the contract riders of rock stars who were just trying to make sure that more important contractual obligations were not being overlooked by concert venues. Through the years, candy sorting has become a classic problem for hobbyists to solve in various ways.

Today’s commercial aircraft are packed to the elevators with sensors, computers, and miles and miles of wiring. Inside the cockpit you’re more than likely to see banks of LCDs and push buttons than analog gauges. So what’s that mean for the intrepid home simulator builder? Modern problems require modern solutions, and this 3D printed simulator is

Have you made an infinity mirror yet? They’re pretty much a rite of passage project at this point. But unlike that DIY power supply, most of them serve no function beyond looking cool (not that there’s anything wrong with that). Might as well make it do something, right? [How Do You – DIY] has a built
IT’S ABOUT TIME WE SAW ANOTHER INFINITY MIRROR CLOCK Continue Reading
Delta robots are machines with three arms designed to move at high speeds and perform precise tasks. The three arms are connected to a universal join at the base, and the device uses parallelograms that restrict the movement avoiding rotation. As a result, they can move in x, y, and z plane and have high

The SFM4200 mass flow meter is a new star in the Sensirion range. Thanks to its high pressure resistance, it can be operated at pressures of up to 8 bar and measures flow rates up to 160 slm with a rapid signal processing time of 0.5 ms. It is particularly suitable for gas mixing in

A group of researchers led by Nick Vamivakas from the University of Rochester has successfully produced particles which have negative mass in an atomically thin semiconductor material. According to the researchers, they have created a device that can generate LASER light using a significantly small amount of energy. All made possible with the help of this so-called negative mass particles. Quantum physicist Nick
