Here’s an automatic minder to keep your stairway alighted while you’re near to it. One presence sensor wired to a microcontroller scans its environs and automatically activates a light source when it sees an object. […]
If you build battery/usb powered electronics projects, often you’ll be in need of a high-voltage power supply. That is a power supply that has an output voltage higher than that catered by the battery. One […]
In this article, I’ll dig into everything you need to know when it comes to the build of your own minuscule wired/wireless spy camera system. Since the spy camera itself is one of the most […]
Here’s a simple and clever way to build a toggle switch with a quite popular, highly available, and cheap CMOS logic chip CD4049UB. Since the little electronic toggle switch presented here is an easy to […]
Aware that a particular circuit is needed to measure electrical conductivity (EC) of a liquid. Since the conduction of current through a water solution is mainly dependent on the concentration of dissolved ionic substances such […]
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 […]
