This is an a simple Tone Control Circuit using TDA1524A. Is the heart pillar in the work that is IC chip diagram of Philip. You can use a tone control or a portion of the lower portion of fines sound, treble and balance to get all setly can be extended by a given signal power can reach up to 3 Vrms with 20 dB and rates expansion are guilty are cra

zy just over 0. 014% with a frequency of 1 kHz and important. The circuit is not difficult to build a team and soon, then old suit of education or be used indoors or outdoors can apply the work should be done. Duty cycle starts from the input power supply built into the pin 3 is the positive voltage and negative voltage to pin 8, this circuit will only Class C and R of the devices to filter out frequencies in different areas. Some may work then. When the signal from the sound source to pin 15 of IC1, the input signal is coupled through C1 and C2 signals from each channel. Left and right, then the IC signals are amplified with the C6 and C4 for controlling the frequency of the sound from the Department that the switch S1 is the option of using the tone control a region or sector will adjust the bass Cape C5 and C3 act as control VR1-VR4 frequency to adjust the volume, balance, treble and bass, respectively. Then the signal was expanded and adjust the frequency, and sends the pin 8 and pin 11 of audio IC of each box R1 and R2 will serve to diminish the right signal And the signal coupling through C9 and C10, with R3 and R4 removing DC comes from the earth to the C11 and C12 will be to remove high frequencies from 70 kHz up. A land, and then sends the signal to the output signal and a voice came out clear.
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.....
