Flickering Torch Bulb
What is the simplest circuit you can think of for building a flickering torch bulb or torch bulb flasher/blinker? How many components do you need? This little circuit uses only a few common components, no […]
Tutorials on electronics for beginners, hobbyist, and experienced geeks. Electronics is a vast area that covers analog and digital systems. Codrey explains how to build your own analog circuits and transforming them into digital blocks.

After seeing an old LM324 chip-based thermostat kit in my attic, I decided it was time to whip up a quick refresher on the far-famed LM324 quad operational amplifier IC. I hope it can be […]
This post shares the design idea of a simple and cheap door status display panel with tristate indicators. The tristate visual indication features three independent modes viz. steady red (busy indicator), steady green (free indicator), […]
The Household 9V Battery Tester presented here is not very accurate and is probably better as an estimating tool than a precise battery tester. I still highly recommend building this little project as it is […]
Like many other Chinese funny gadgets, liquid-activated light up ice cubes are now flooding our markets. We can easily buy many of them for a few bucks, but what about making similar beautiful cubes ourselves? […]
I have been experimenting with wireless charging for a few years now, including building some fun projects with readymade Qi wireless chargers and wireless charging modules! I think you also know that it is pretty […]
So here is an out-of-warranty Pigeon Multipurpose LED Flashlight that just suddenly stopped working so I figured why not take a crack at it. I bought it on discount sale from an Indian online store […]
After seeing an inspiring post on a website about making a simple automatic pet feeder using a cheap stepper motor, I decided to re-do some trivial experiments with it. For that I chose the very […]
In this short post we will again take a nimble look at electromagnetic relays and the electronics associated with them. As we all know, an electromagnetic relay is a simple electromechanical switching device that uses […]
I have already outlined many times here how to build very simple noise makers or noise generators. Also, there are many more outside this space, here is a randomly picked project example Arduino White Noise. […]
