Visualizations are an important part of a music player. They provide the user with something to feast their eyes on especially when the music has no video. For today’s tutorial, we will build a visualization device, capable of providing a visual representation for any kind of music fed into it. The goal of this project […]

Incandescent light bulbs at the nanoscale


https://www.electronics-lab.com/incandescent-light-bulbs-nanoscale/

Using tiny arrays of carbon nanotubes, a team of researchers at Rice University has designed nanoscale incandescent light source that could be tuned to precisely emit at specific wavelength, based on the materials’ configuration. The so-called nanoscale thermal emitters described in a paper titled “Non‐Hermitian Selective Thermal Emitters using Metal–Semiconductor Hybrid Resonators” published in the […]

Window Comparator – Window Detector with relay output


https://www.electronics-lab.com/window-comparator-window-detector-relay-output/

A window detector circuit, also called window comparator circuit or dual edge limit detector circuit is used to determine whether an unknown input is between two precise reference threshold voltages. It employs two comparators to detect over-voltage or under-voltage condition. This circuit utilizes two comparators in parallel to determine if a signal is between two […]

Class AB Amplifiers


https://www.electronics-lab.com/article/class-ab-amplifiers/

Introduction Class A amplifiers offer a very good linearity of the output, meaning that the signal is faithfully reproduced, however their efficiency is very low, around 20-30 % in most of the cases. On the other hand, class B amplifiers present a very high efficiency up to 78.5 % but cannot reproduce the output faithfully. […]
