This is a fun and educational mini project for students and hobbyists interested in basic electronics. Concepts Covered: Transistor Switching […]
CD4047 Inverter, 100 watt Power, Also why its not good?
In this project, we will make CD4047 Inverter, and also we will discuss why they are not a good solution. An inverter is a device that converts DC voltage to AC. They are very important for power backup in a remote location like villages where there is a frequent power cut off problem also in […]
PWM controller for DC Motor using 555 timer IC
Pulse Width Modulation PWM controller. PWM is a technique in which the amount of current going in a circuit can be controlled by chopping the Direct current using a gate or transistor that is changing its duty cycle (on-off time) you should see this article flashing of LED using 555 IC. This article is about […]
How does metal detector works? fully explained
Introduction: A metal detector is a device that can detect metal which may not be seen directly. The simplest kind of metal detector can be made using an oscillator, two inductor coils, and a detector or indicator. Here we will talk about how does metal detector works its construction applications and the importance of metal […]
5G technology good or bad?
Introduction: 5G technology is the upcoming generation of mobile communication technology. It is the 5th generation of mobile communication technology after 4G. It is 20 times faster than 4G. 4G has a peak speed of 1Gbps whereas 5G can go to 20Gbps. Here we will see whether 5G is good or bad. Facts about 5G […]
