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 made a little purchase in the midway of December, and there’s a nice packet waiting for me when I got home from Xmas holidays – A couple of AC230V/2000W light dimmer/speed regulator modules! The […]
Governing the speed of a motor is very important in many situations especially in mechatronics. By measuring the speed of a motor, we can then adjust the motor’s speed to exactly what we want. Along […]
I’ve a few mini pocket weight scales. What I love about the cheap device is that it uses a pretty little load cell. When a scale get worn out, perhaps you can reuse its 4-wire […]
A Gas sensor serves to detect and measure the concentration of gas in the environment. Nowadays you can find many different types of easy to use gas sensors, especially in MQ series. In this article, […]
Often you’ll need a simple pulse width modulation generator circuit to test or run small dc lamps and motors in your electronics projects. There’re ways of creating cheap and practical circuits at home, and today […]
Simple flame supervisor is nothing but a little flame status monitor. The theme of this play is to build a cheap device to provide an alert when the flame under supervision runs out unexpectedly. Admittedly […]
Very recently I wanted a couple of Hall-Effect Switches again for some random experiments, hence placed an order for a bunch of A3144 Hall-Effect Switch ICs. The online retailer quickly delivered the packet at my […]
If you’re an active electronics hobbyist or maker, sometimes you may get a request from your close friend or neighbor to build a very economical table lamp or bedroom lamp for him/her but with some […]
Tilt sensors come in umpteen flavors. The cheapest and most common flavor is the belittled SW-520D tilt sensor module you can find everywhere. Key component in the demoed module is one SW-520D ‘roll ball switch’ […]
With this article, I’m trying to share one simple idea on how to build a single-key touch pad sensor/switch using a quick and cheap Chinese module. We can easily build a simple touch sensor using […]
