In this section you will learn and build simple electronic circuits projects. You will make interesting analog electronic circuits useful in daily life. Moreover, you will know electronic circuit design using circuit elements.
The circuits include home made electronic circuits, hobbyist circuits and prototypes.
Thermo fans are an important part of thermal management for high-power electronics because when the temperature increases, performance can suffer, and beyond the point where performance degradation begins, excessive temperature causes catastrophic damage to delicate […]
You cannot prevent the power grid from going down and up, but you can take steps to ensure that an electrical disturbance does not take your sensitive electronics devices down with it. When power is […]
The power sequence is the sequence in which the power is applied and shut down between steps in a sequence. A power sequence is used when there are devices with different power supply voltages mixed […]
In many posts, we saw how to use a common transistor as an electronic switch to drive power loads of voltage and current mightier than those we could deliver with the I/Os of a standard […]
Most commercial model rocket launch controllers available to buy are either expensive or do not have desired features. After a lot of Googling, I found nothing that fits my little budget. Actually, I wanted a […]
This is the concluding part of the LED strobe article published last year (https://www.codrey.com/electronic-circuits/led-strobe-primer-part-1/). During this long period (sorry for the inadvertent delay) I have already shared several strobe light ideas. But the sequel to […]
Welcome to the lovely sound of analog electronics! Now I’m building some white noise and pink noise generators for an upcoming amateur audio project. In this article, you can see a few basic design ideas […]
Even though I have a large collection of TP4056 modules for charging lithium-ion cells, I recently found a pretty small charger module – TP5100 – capable of charging a single lithium-ion cell or two lithium-ion […]
This guide details how to build a simple sawtooth wave generator using the venerable 555 timer chip that can be used to test some of your homemade circuits and projects. Got any questions? I’m happy […]
Peephole proximity sensor presented here is an inexpensive nearness detector for hobby electronics projects and home automation applications, where we need to sense the presence of a person (or object) in front of an entry […]
