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.
This 5V microcontroller power rail guard is a quite simple solution to add an overvoltage protection (OVP) mechanism between the 5VDC power source and your microcontroller board. In short, this little design uses a Zener […]
In this post, I will attempt to share the design idea of a doorbell sensor that can be build using just a handful of inexpensive and easily available electronics components. When cleverly integrated into your […]
Recently I have received a few messages from a follower who is interested in making a simple relay box that will help him operate some regular electrical devices using the control signal from a common […]
Every once in a while, I have found myself needing a quick circuit to blink a light emitting diode. It is quite easy to build simple microcontroller circuits which performs this task thru a few […]
The real inspiration for this post actually came from lots of lame designs seen on the web. The last drop was a reasonably great written article presenting a number of blueprints to build timer circuits […]
You do not need to read this post if you are willing to thoughtlessly throw away your hard-earned money to buy a car power probe that only has very cheap electronic circuitry inside. On the […]
This post explains how to build a Hyper LED Switch using a set of simple and inexpensive electronics components that are available everywhere, you can even find them in your junk box. So, what is […]
Once again, the design concept of an Eternal LED Blinker configured to operate from a DC supply in the 3V to 12V range and consisting of only a few components. Since its power consumption is […]
Solar powered novelty items such as an electronic candle have become very inexpensive and common place. Looking from the outside, it consists of a small solar panel to harvest power from daylight and some sort […]
The water activated LED marker is a great scuba diving or night diving accessory. Its bright marker light turns on when its sensor probes come into contact with water and turns off when the probes […]
