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.
I have a great collection of cheapo Chinese DC-DC stepdown converter modules that I use for everyday purposes in my lab. Most are the good old but still popular LM2596S modules available under $1 from […]
After some successful experiments recently, I was convinced that measuring current with a WCS series current sensor is easy and straightforward. It’s a cakewalk – after connecting the WCS current sensor’s pins in series with […]
In this post, you can see the design of a little low-voltage universal LED flasher. The flasher is in fact a standalone module but it can also be used with most 3.3V (or 5V) microcontrollers […]
It’s only been three weeks since I put together an Arduino Night Light for the kids, and it already made my neighbour’s kids curious! Anyway, long story short, once I had finalized my design thought, […]
I had to develop a quick design to cook up a simple anti-rape alarm/personal alarm, but using only a handful of inexpensive and readily available electronic components. I came up with this solution. I am […]
I’ve recently completed the basic design of a general-purpose analog constant current generator employing easily available electronics components. This is a simple circuit that is easy and cheap to build and is very useful especially […]
Making a micro-LED strobe is much simple than you think. You can simply use a couple of common transistors to build your own LED strobes. I know, there’re countless ICs in front to help you […]
Recently I have been experimenting with a Chinese solder fume extractor and was interested in using a commonly available BLDC cooling fan to build a close replica of that pretty cute gizmo. Since I have […]
An audio-light modulator is a funny device that controls the intensity of one or more electric lamps in response to the audio signal input. Such a device is ideal to give the rhythm to any […]
Why use an inground uplighter (buried uplight)? The answer is simple – when lighting a static object with a buried uplight its visual impact can be stunning, whilst no one pays attention to that minuscule […]
