As shown for the TRIAC dimmer circuit diagram, working principle is: power, 220V lamp VR4 R19 through C23 charge. Because of two-terminal voltage capacitor is not mutated. char

ging will take some time. the charging time VR4 and R19 size is determined by the smaller charge. sooner. slower. the greater the charge on the C23 when voltage of about 33V to charge when turned on. DB1 controllable. silicon is also conducting thyristor.. after a current flows through the bulb in the bulb lit up. . with the DB1 conducting voltage on C23 is completely let go. DB1 and also will be cut off.. thyristor bulb goes out. they were the same as the beginning of the cycle C23. because time is short persistence of the phenomenon of the human eye, it appears to have been light bulb bright, charge and discharge time shorter. the brighter the bulb, and vice versa. R20 C24 protects SCR. if used on a resistive load can be omitted. If it is used in the inductive load, such as would add to the motor, this circuit can also be used for motor speed control.
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.....
