This is a power supply circuit that produce voltage 12 to 24 V. It is very simple, doesn`t need regulator just bridge rectifier, filter capacitor and transformer. A bridge rectifier makes use of four diodes in a bridge arrangement to achieve full-wave rectification. This circuit will give you 15 VDC at up to 3A. WARNING: Don`t touch any part of th

e circuit when the circuit is running (connected to the powerline), this circuit is not isolated from mains supply. This is transformerless power supply circuit. This circuit is used to generate fixed voltage power Continue reading †’. Applying the filtered and rectified AC input to a high-input-voltage linear regulator is the simplest way to produce low current level from an AC source. However, it will causes the power dissipation in the regulator. The power dissipation can be Continue reading †’. A diode bridge, a step down transformer a linear regulator(U1) and some filtering capacitors can be used to build a Linear power supply. This circuit has some advantages such as this circuit has high output current and can give multiple Continue reading †’. This is a The Crowbar circuit. This circuit is used to prevent the load from damaging. This circuit utilize a zener diode. The regulator steps down the 12V input to 5V. The load will damage when the regulator is fail Continue reading †’. This is compact power factor controller circuit. It stabilizes device`s electrical demand to give best power factor characteristic of many types of loads. In many application, a direct rectification of the AC line followed by bulk capacitor filtering is used Continue reading †’.
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.....
