Not long ago, we published an article related to this topic. This time the prime aim of this revised article is to serve as inspiration for electronics hobbyists who are making projects which involve driving […]
What should you do when you hear a midnight door knock? Although there’s no quick answer to this question, you must keep in mind that you and your locked door may be the only obstruction […]
This prefatory article focuses on Avalanche pulse generators commonly used to generate fast rise time pulses. Often fast pulses are required when measuring slew rate or propagation delay, and for sampling. Fortunately, avalanche breakdown of […]
The Digispark Attiny85 development board is not only for novices – it’s also a tiny but great microcontroller development board for matured electronicists. Sure, the Digispark board offers almost everything you need i.e. digital I/Os […]
A family party or a small get together, we all need some stunning music there to lighten up the festive mood. Well, today I’m going to talk about a simple do-it-yourself project that will give […]
I volunteered to design a simple and inexpensive isolated power mosfet switch to control some electric loads by a ‘pulsed’ low-voltage input signal. There are of course superb solid state relays (SSRs) that we could […]
This article introduces a laser receiver sensor module available on the web. The module, named “Laser Receiver Module Non-modulator Tube Laser Sensor Module”, comes as a cheap module usually without a user guide. So it […]
There seems to be a lot of confusion among electronics hobbyists about how a rotary encoder (knob) works and how to use it with electronics projects. Today, we’ll be examining a very cheap and easily […]
In this article you can see an ultra simple circuit of a lightweight, truly portable, and compact anti-snatch alarm. This trembler alarm is battery operated and features a tone generator capable of drawing quick attention […]
One issue that has caught quite a few electronics hobbyists out when they build simple projects on a breadboard is the selection of a right power supply source. The most popular MB-102 breadboard comes with […]
