PORTLAND, Ore.—Today Yole Development predicted that power transistors would radically shift from silicon wafers to silicon carbide (SiC) and gallium nitride (GaN) substrates—to achieve higher power in smaller spaces, according to its GaN and SiC Devices for Power Electronics Applications report. One of the big drivers behind the shift is the electric vehicle (EV) and […]

We are building another enjoyable weekend DIY project. This is an audio power amplifier based on LM1876 which can deliver up to 20W per channel into 4 or 8 ohm load and guarantees less than 0.1% THD + N (Total Harmonic Distortion + Noise). The amplifier is powered by -15 0 15 VAC symmetrical supply.

Oscilloscopes and Signal Generators are two essential electronics devices to create and test electronic circuits. Unfortunately, these devices are very expensives for students starting electronics, or makers who want use electronic circuits in their creations just once… The idea of my project is to rethink your smartphone as a portable, powerful and secured platform, able

Written by Rui Santos – Get free updates of new posts here In this project you’re going to make two ESP8266 talk with each other. How it works? You’re going to set one ESP as an Access Point (Server) and another ESP as a Station (Client). Then they’ll establish a wireless communication and the Client sends a message
