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.
Back a few months I got one Boom Touch Wireless Portable Speaker from a friend abroad. Boom Touch is a compact speaker which amplifies audio signals without cables or Bluetooth. The Boom Touch uses inductive […]
Monitoring entry/exit doors on time is not always an easy task for everyone. Fortunately, with a handful of electronic parts you can build yourself an expansible door sensor that will not only give a timely […]
Nothing mattering to see a circuit turning light emitting diodes (LEDs) on and off. If for certain applications, brightness of the LEDs could be adjusted in a continuous manner, with a simple dimmer circuit you […]
Nowadays solid state relays (SSRs) can be found in almost every online electronics store, and SSRs are certainly the most ‘silent’ relays available. However, I would like to point out at first that SSRs are […]
The quick way to build an electromagnet based project is to buy one lifting electromagnet with enough lifting and holding power to fulfill the design requirements. Such compact and powerful lifting electromagnets in various shapes […]
Recently when I was developing a digital light controller project, I wanted to have the interface isolated from the common ground to avoid spurious noise and other issues. Since I didn’t have a quick solution […]
Here’s the simple circuit of an ultra-sensitive knock sensor for microcontroller-based electronics projects. It’s in fact a piezo knock sensor monitor based on a single transistor, and designed carefully to work with 5V (or 3.3V) […]
Audio signal injector is a must to have little tool for troubleshooting audio circuits. Connecting the audio signal injector to the circuit under test you should be able to hear its tone in the speaker […]
I have received numerous requests for a simple, cheap and entry-level ham radio world project and the result is this do-it-yourself Morse Code Practice Oscillator usually called simply as Code Practice Oscillator (CPO). This project […]
Aim of this article is to provide a simple circuit to drive EL (Electro Luminescent) components. The minuscule driver design you can find here will render decent power to lights up a few feet of […]
