The fluorescent with reactive power compensation As ballast is an inductive load. It needs to consume some reactive power, causing the power factor of fluorescent lamp decreases. It affects the ability of full-powered devices, and reduces the voltage of.... -
We can use UBA2021 for 600 V lamp controller and half-bridge driver IC for high-power. The UBA2021 is a long-life CFL/TL applications. It`s equipped with.... -
The UBA2024 is a half-bridge IC and 550 V lamp controller. This device is equipped with 9 ohm switches that espouses standard CFL applications up to 15 W. The.... -
A 40 watt fluorescent (tube lamp, TL) or two 20-watt tubes in series will be driven by this circuit. The transformer is wound on a ferrite rod 10mm dia and 8cm.... -
A 40 watt fluorescent tube lamp or two 20-watt tubes in series will be driven by this circuit but this circuit will produce less brightness than usual, since.... -
This circuit shows a solid-state fluorescent-lamp starter that uses a SIDAC. In this circuit, the ballast is identical to that used with a conventional glow-tube starter. .. -
CCFLs are often used to backlight the LCD displays of portable computers Such lamps require a high-voltage sine-wave drive. This circuit provides such drive and permits lamp intensity to be varied continuously and smoothly from zero to full intensity. Notice....

This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of.... -
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is.... -
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to.... -
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This.... -
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the.... -
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,.... -
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the.... -
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power.... -
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
Firstly, we will describe the "add-on" version for the 5x7 Display as this is the cheapest...
This circuit can accept positive or negative or differential control voltages. The output...
This system operates on the principle that capacitance loading of an oscillator will lower its...
When I spotted this April, 1955 issue of Popular Electronics magazine at a swap meet, I...
The loads (2 or more solenoids in parallel) share a 12V supply and are individually switched to...
Martin KH6MB designed an antenna tuner for use with end-fed half-wave vertical antennas for use...
A very interesting remote controlled alarm circuit using TSOP1736. Routing of an electric cable...
All you need to do is substitute transistors for the tubes used in these fundamental oscillator...
However, for applications needing many LEDs, this becomes extravagantly inefficient and it is...
Circuit works: When normal inspection work where the voltage across the resistor R2 through, RP,...
