RGB Light Strip Controller Circuits
In this post we are going to see how we can construct an RGB LED light strip controller circuit for PC cabinets and also for general decoration purposes. In this post we will construct a couple of RGB light strip controller designs, one for a PC cabinets and one for general purpose which can be […]
Neon Tube Driver Circuit
The high-voltage neon tube driver circuit discussed in this article generates 500 volts of high-frequency AC (15 kHz). This circuit may be used to brightly illuminate all types of neon tubes. Neon ranks among the best when it comes to striking, eye-catching lighting displays. Virtually every industry, from pizza restaurants to clothes boutiques, uses neon […]
Darkness Activated PIR Lamp Circuit
A very simple darkness activated or night activated PIR lamp circuit project has been explained in the following article. Further in the article we also learn how to upgrade this circuit with an additional emergency lamp facility. This darkness activated PIR lamp will work as I have explained below: It will remain deactivated or disabled […]
Automatic Night Activated Wireless Light Circuit for Paintings
In this article I have explained a basic wireless LED light circuit that may be used to autonomously turn on LED lights to illuminate artworks at nighttime.
LM386 Amplifier Circuit [Working and Application Circuits]
The IC LM386 is a 8-pin tiny power amplifier chip, specially made for operating under relatively low voltage parameters, yet provide considerable amplification. IC LM386 amplifier circuit becomes suitable for applying in small low power audio gadgets like in FM radios, door bells, telephones etc. Let’s begin the IC LM386 amplifier explanation by studying its absolute maximum ratings […]
