The article discusses research by physicists Changhyun Ryu and Malcolm Boshier, reported on the research website Arxiv.org, on the use of lasers to create a stable circuit board out of Bose-Einstein condensate rubidium atoms by using the lasers as optical tweezers, and possible uses of the ...
A relay transistor driver circuit can be considered a great example of a boost converter circuit. The flyback diode connected across the relay is introduced to short circuit the reverse back EMFs from the relay coil and to protect the transistor whenever it switches OFF. If this diode is remov...
Step 1: Create Or Find A Circuit Diagram Before you start drawing wires and stuff, you need to know what circuit you want to build. So you need a circuit diagram. You can either find one that someone else has made, or you can design your own from scratch. I recommend starting with s...
So you see how the transistor allows a circuit to be an LED driver. Without it, there wouldn't be enough power to drive it. The point of this circuit is that if you have insufficient current output, you can create a driving, or amplifying, so that you can have sufficient current. LED...
In this circuit, we will show how to build a voltage sensor circuit. A voltage sensor circuit is a circuit that can sense the voltage input into it. If the voltage reaches a certain threshold, then an indicator, such as an LED, will turn on. ...
In this tutorial, you’ll learn how to build an automatic night light circuit that turns on when it gets dark. It’s a simple circuit that you can build on a breadboard. This circuit shows you how to do it with an LED. But you can use the same principle to turn on bigger and bri...
These components are both passive andactive components. The circuit schematic comprises the arrangement of these components in a readable format. Also, a schematic enables viewers to know the connectivity among several components. With this, it is easy for designers to understand the arrangement of ...
LED flashlight circuit with an inverter IC is an effective way to convert low-voltage DC power from batteries into high-voltage AC energy for powering LED lights.
Before diving in, I needed to grasp what a PCB actually is. What Exactly Is a PCB? A Printed Circuit Board (PCB) is a board made from a non-conductive material that supports and connects electronic components using conductive pathways, known as traces. Essentially, it's a platform that or...
A simple circuit may be constructed with the aid of a battery, alligator clips and a component load. It is a straightforward project and requires few materials. Learn how to create a simple circuit using a mini-lamp.
