The V.U. meter that works with the integrated amplifier circuit.The signal will sound, the audio amplifier circuit into VU meter circuit.And will show the level.... -
A VU Meter is used to display the power level of the audio, it also is beautiful. When you go to the electronic equipment store to buy the VU meter kit, with the assembly various parts on their own or the style ready to use. Most of us are using the.... -
Expensive stereo is general often have VU meter come to and for help show max power the stereo not too much. For radio tape general plaything has will no VU Meter. I then think to seek Multi meter use can replace. By use Range 100uA and electronics equipment.... -
A nice schematic for an lm3915 VU meter. I have attempted to create a band pass filter in order to only input part of the audio frequency spectrum into the VU meter circuit, this is becuase I plan to have 5 of these circuits to make a spectrum analyser or.... -
* This meter looked like it works well: YouTube - IndikG tor vybuzenG s LM3915 but the schematic is quite different. Google Translate If I followed that schematic, do you think everything would still work You should use a peak detector circuit at the input.... -
This simple VU Meter may be used in variety of projects. Since real electro magnetic type VU Meters are no longer available or too expensive, I decided to make this one using LM3914 and 10 LEDs, which I can use in my other projects... -
Hi all, i`ve recently bought the dantimax thatmic pre amp and i was wondering if anyone could point me in the right direction to install a vu meter.... -
This is a quick how-to guide for making a stereo VU meter using the LM3915/LM3916. The LM 3916 is an integrated circuit (IC) that takes analog voltage levels and drives 10 LEDs, LCDs, or vacuum fluorescent displays to represent digital voltage levels just.... -
If you look carefully at the schematic you will notice the input is feed into the voltage divider. This is because the Schmitt Triggers all turn on a.... -
This simple circuit is based on the well-known integrated circuit LM3915. The main characteristic of this integrated circuit is its power to manage 10 LED-s (Light Emitting Diodes) in logarithmic scale with a difference between the 3dB LED-s, which it can.... -
The circuit is based on an LM3914N bar graph display driver device (IC1), which can be used to drive up to ten LEDs. This is connected so that with OV12 at the input only the first LED indicator switches on. This simple peak reading VU meter circuit uses six.... -
This circuit can be used as a small beacon or marker light, amd toys or novelty items. R1 is an LDR that has‰¥10 k © dark-resistance, or a CDS photocell. C1 determines the flash rate. .. -
Used in high-quality stereo cassette deck operating from AC line or battery. Meter rectifier bridge is in feedback loop of opamp, to give highly linear AC/DC conversion with flat frequency/amplitude response and short voltage rise time at low cost. .. -
This circuit provides a cheap alternative to the LM3915 series LED displays. The meter relies on a square-wave oscillator built around two CMOS analog switches, which alternatively selects the right and left channels for monitoring and display. The selected.... -
A portable CD player, radio, cassette player, a couple of microphones and PC sound card. I am feeding these into the inputs of an audio mixer the output of which is attached to a pair of active loudspeakers. I want to be able to monitor the signal levels.... -
This project creates a RGB LED VU Meter which is controlled via USB by a Windows 7 or Vista host machine. The project serves several purposes: Firstly, it demonstrates how to read audio information from the Windows machine and pass this over USB to 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.....
