In case of Japan, the electricity to be using in the home is 50 Hz or 60 Hz. In case of 50 Hz, the 1-cycle sine wave occurs the 50 times for the 1 second. 60 Hz are the 60 times. There is a way of making make the Lissajous as the way of understanding that the sine wave relates to the circle. In case of the sine wave which doesn`t have the distorti

on, the Lissajous becomes the true circle. The amplifier becomes the saturation state when the signal which returns to the amplifier through the feedback circuit is too big and the beautiful signal doesn`t come out. The phase means the position of the signal. At the electronic circuits, phase of the input and the output depends on capacitors, the coils, the amplifier itself. Because it is, it doesn`t oscillate when not adjusting the phase of the input signal. The part which is composed of C1, C2, R1, R2 becomes the positive feedback circuit of the operational amplifier. With it, the operational amplifier works in the oscillation. Also, the circuit sets the oscillation frequency in the damping time constant of the CR. This oscillator begins the oscillation when it makes the mu factor equal to or more than 3. At less than 3, it doesn`t oscillate. The beautiful signal doesn`t come out by output`s being saturated when the mu factor is more than 3. The low pass filter make pass the low frequency signal and blocks the high frequency signal. The signal flows through the grounding with C1 and the output voltage becomes low when the frequency becomes high. Oppositely, the high pass filter make pass the high frequency signal and blocks the low frequency signal. It is because the signal which passes C2 becomes little when the frequency becomes low. When combining these two, the signal in the area that the characteristic is the...
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.....
