3 Channels Audio Splitter Amplifier Circuit Diagram using TL084

This is the schematic diagram of 3 channels audio splitter amplifier circuit which built using op-amp IC TL084. The 3 channels amplifier output distribution applies a single TL084.   3 Channels Audio Splitter Amplifier Circuit Diagram The very first step is to capacitive coupling having a p. 1.0 ~ electrolytic capacitor. The entries are railways Vee Y2 or 4.5 V. This enables working with an individual 9V power source. A voltage gain of 10 (1 M?/100 Kohm) is obtained in the first stage, as well as the other three floors are connected as a unity gain voltage followers. Every single output stage drives independently through an amplifier output 50 pF capacitor towards the resistance of 5.1 k ohm load. The response range is flat from 10 Hz to 30 kHz.

Simple Automatic Street Light

There have been lot of problems in street lights. Major problem in some places is every evening a person has to come and switch ON the street light and it should be again switched off in morning. Yes, this may not be the situation in everywhere but exists in many places. So this problem can be overcome by using a simple circuit. Below shown circuit will be automatically switched ON and OFF during night and morning times respectively. Circuit diagram : Simple Automatic street light Circuit Diagram In above circuit R1 can be used to adjust the sensitivity. And the working of the circuit is very simple. The LDR will have very low resistance during day time so the transistor Q1 will be in OFF condition. And during night time the resistance will be very high so automatically the transistor Q1 will be ON. The Q1 is PNP transistor and the emitter of Q1 is given to base of Q2. So the Q2 transistor will be ON only if the transistor Q1 is ON. The TRIAC is used in the circuit to make is circ...

Apples Next iPhone to Arrive Sept 10

Apple will unveil the next edition of the iPhone at a major press event on Sept. 10, according to All Things D.Other than the purported date for the unveiling of the so-called iPhone 6, the site's Ina Fried did not offer any details about what else we might expect from Apple with the arrival of the company's first new smartphone since the debut of the iPhone 5 last September. If Apple does lift the curtain on its next-generation iPhone on Sept. 10, it would be two days short of a full year since the iPhone 5 was revealed. While Apple CEO Tim Cook is rumored to be under pressure from Apple's board to step up the pace of innovation and product release schedules, that lag between new iPhone releases wouldn't be particularly unusual for the company—Apple went 16 months between introducing the iPhone 4 and iPhone 4S , for example. But as Fried noted, even as Apple has continued to enjoy robust sales of the iPhone this year, the company has seen its overall share of the gl...
