This tutorial provides a guide on how to set up an Arduino to measure the capacitance of a capacitor. This can be useful if the capacitor is unlabeled or if it is self-built. Capacitance is an object’s ability to store an electric charge. Reasonably, this object is referred to as a capacitor. A capacitor that […]

An alliance led by IBM Research, together with New York academic institution SUNY Polytech and with Samsung and GlobalFoundries, has produced 7nm (nanometer) node test chips with functioning transistors. Continuing semiconductor scaling down to feature sizes of 7 nm is expected to yield further gains in performance, and lower power levels, but in IBM’s words,

Pleasant actuation characteristics and reliable features of a push button switch Marquardt series 1840 make it attractive for all applications where you require control by a push. Classic push-button switches are favorite for many decades, maybe also because they´re well known already from the beginnings of electronics. Probably, a nostalgia is not the only reason

So recently I got a Raspberry pi and a 16×2 character LCD screen , I thought , lets make a simple game that can be played on the lcd. my first instinct was to code directly for the lcd on the pi , but as I started coding I realized that the clutter of having

If sensitive analog systems are run from one supply without the sufficient bypassing to eliminate noise, undesired degradation in a system’s performance will result. This application note provides insight into suitable techniques to overcome this roadblock. For more detail: App note: Eliminate noise through proper supply bypass filtering

Following simple programmed rules, autonomous robots arrange themselves into vast, complex shapes Cambridge, Mass. – August 14, 2014 – The first thousand-robot flash mob has assembled at Harvard University. “Form a sea star shape,” directs a computer scientist, sending the command to 1,024 little bots simultaneously via an infrared light. The robots begin to blink

Menlo Park, Calif. — In a study that could improve the safety of next-generation batteries, researchers discovered that adding two chemicals to the electrolyte of a lithium metal battery prevents the formation of dendrites – “fingers” of lithium that pierce the barrier between the battery’s halves, causing it to short out, overheat and sometimes burst

Embedded modules may surprise you by their contribution and an overall costs savings. As we know „embedded module“ is a quite wide term and it can represent a powerful microcomputer with OS, but it can also be a significantly simpler module with a microcontroller and peripherals, still able to add considerable functionality to a target
