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 […]
There are different types of pulse width modulation (PWM) circuits out there online, but for the purposes of sharing a new post, I am showing you an Arduino Universal PWM Driver project at this time! […]
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 […]
Thermo fans are an important part of thermal management for high-power electronics because when the temperature increases, performance can suffer, and beyond the point where performance degradation begins, excessive temperature causes catastrophic damage to delicate […]
What is sound energy and how does it interact with a non-Newtonian fluid (https://en.wikipedia.org/wiki/Non-Newtonian_fluid)? This is just an attempt to get a variety of non-Newtonian materials “dancing” on a subwoofer using sound waves. Inspiration – […]
Nowadays you can see many dc power supply modules equipped with an additional remote-controlled shutdown (or on/off) feature. It allows you to control the power supply output with a signal switch or transistor. Some time […]
You cannot prevent the power grid from going down and up, but you can take steps to ensure that an electrical disturbance does not take your sensitive electronics devices down with it. When power is […]
