LED Star Circuit
This circuit can be used like a tree ornament, however the LED star circuit explained here has a variation; it’s completely electronic and it provides the impression of an exploding […]
Cube Light Circuits
In this post we learn how to make simple yet fascinating cube light circuits, in which LEDs are connected inside a plastic cube to produce interesting illuminating effects. All the […]
Line Laser Controlled Motor Alignment Circuit
The post explains a simple line laser controlled motor driver circuit, which works by responding to a precision horizontal laser line, generated from a line laser level device, and automatically […]
Simple FET Circuits and Projects
The Field-Effect Transistor or the FET is a 3 terminal semiconductor device which is used for switching high power DC loads through negligible power inputs. The FET comes with some […]
Ultrasonic Hand Sanitizer Circuit
The ultrasonic hand sanitizer circuit detects the presence of human hand through reflected ultrasonic waves, and triggers a relay solenoid pump momentarily for dispensing the sanitizing liquid on the hands […]
