by Lucky @ elektormagazine.com build a LED display clock able to display temperature, humidity and air pressure. He writes: What do you do when you want to design ‘something’ with a vintage or modern display? A clock of course, and this is our first design with RGBDigits:...

In this easy Arduino Tutorial educ8s.tv is going to show us how to create a Menu on a Nokia 5110 LCD display. This is the project we are going to build. In the display a simple menu appears, and with the help of three buttons I can navigate up, or down and select a menu item. Let’s...

The LM3886 is a high-performance audio power amplifier capable of delivering 68W of continuous average power to a 4Ω load and 38W into 8Ω with 0.1% THD+N from 20Hz–20kHz. The performance of the LM3886, utilizing its Self Peak Instantaneous Temperature (°Ke) (SPiKe) protection...

SiFive, the first fabless provider of customized, open-source-enabled semiconductors, had recently announced the availability of its Freedom Everywhere 310 (FE310) system on a chip (SoC), the industry’s first commercially available SoC based on the free and open RISC-V instruction set...

Creating a smartphone application for your embedded products may be a high-cost process that consumes time and efforts. ImageCraft, a producer of high quality low cost embedded system tools, had developed “Smatr.IO” as a very cheap alternative solution that allows you to add a...

A detailed die photos and reverse engineering of the 74181 ALU chip by Ken Shirriff: What’s inside a TTL chip? To find out, I opened up a 74181 ALU chip, took high-resolution die photos, and reverse-engineered the chip.1 Inside I found several types of gates, implemented with...

LTC3897 is a multiphase synchronous boost DC/DC controller with input surge stopper and ideal-diode controller. The boost controller drives two N-channel power MOSFET stages out-of-phase to reduce input and output capacitor requirements, enabling the use of smaller inductors versus...

T A Babu @ edn.com discuss about a protection circuit for boost converters. Boost converters are particularly susceptible to output shorts as there is a DC path from input to output. Usually a fuse, resettable or non-resettable, protects the system, but it is not always accurate or...
