CircuitDB | Your online circuit repository Aussiemike in Kenya – who suggested that light from a mobile phone’s display screen could be used to trigger a switch.When a brief (free) phone call illuminates the display – the light from the display operates a 4017 based Toggle Switch.And any small push switch – connected in parallel with the LDR – will provide optional manual control. Crystal detector The contact between two dissimilar materials at the surface of the detector's semiconducting crystal forms a crude semiconductor diode, which acts as a rectifier, conducting electric current in only one direction and resisting current flowing in the other direction. In a crystal radio, it was connected between the tuned circuit, which passed on the oscillating current induced in the antenna ... Voice networks, Voice Over IP, IP Telephony rhyshaden Integration of voice into data networks is now become a reality so this document has been written to give an overview of traditional circuit switched voice operation and the elements that allow it to become part of a data network. Electronics Engineering Hobby Projects Scie Electronics Educational Practical Engineering Projects (by J. Singh). Circuit of 89C2051 Based Water Level Indicator with Voice Alarm; Controlling Lights through Parallel Port of PC puter Testing Electronic ponents FIXING A MULTIMETER A multimeter can get "broken" "damaged" and go "faulty." I don't know why, but eventually they stop working. It can be something simple like a flat battery, corroded battery contacts, broken switch or something complex, like the circuitry failing. Electrical oscillations in an L C circuit. Rectifiers ... Electrical oscillations in an L C circuit. A circuit containing only a switch, charged capacitor, and inductor will exhibit oscillator behavior when the switch on the circuit is closed due to a mechanism of repeating discharge and recharge of the capacitor. How to Build a Microphone Amplifier Circuit How to Build a Microphone Amplifier Circuit. In this project, we will go over how to connect a microphone to an amplifier circuit so that we can amplify the sounds recorded by the microphone. TL074 10 Band Graphic Equalizer Schematic circuit ... TL074 10 Band Graphic Equalizer . With graphic equalizer we make selective cutting off or boost, of selected departments of acoustic spectrum. With this way we can adapt the musical reproduction, in the characteristics of space where we hear. Crystal radio A crystal radio receiver, also called a crystal set, is a simple radio receiver, popular in the early days of radio.It uses only the power of the received radio signal to produce sound, needing no external power. It is named for its most important component, a crystal detector, originally made from a piece of crystalline mineral such as galena. This component is now called a diode.

Copyright 1996 2001 Tomi Engdahl Circuit Zone Electronic Projects, Electronic ... In the mid 1970s large numbers of small FM transmitters, operating in the FM radio broadcast band (88 108 MHz) appeared on the market. It started with a self build kit from the Danish manufacturer Jostykit that allowed everyone to build a small FM transmitter for a few Euros. The Creative Science Centre by Dr Jonathan P. Hare Simple demonstration to explore the radio waves generated by a mobile phone. Dr Jonathan Hare, Sussex University, Department of Physics, Falmer, Brighton. Audio circuits to build ePanorama.net Links Audio circuits to build. The following links to circuit diagrams and building projects I have found from other web sites. I have tested only very few of them so there is no guaratee that those circuit will work as expected. Circuit Improvements and Maintenance Procedures for the TS ... Circuit Improvements and Maintenance Procedures for the TS 830S. by Richard L. Measures, AG6K. The ancient TS830S is a still a remarkable radio. Processing: The processor is clean and effective. When an 830 processor is turned on, the S meter at the receiving end noticably increases and the perceived volume increases yet the audio is clean and understandable. Notes on the Troubleshooting and Repair of Microwave Ovens Back to Microwave Oven Repair FAQ Table of Contents. Testing and Replacement of ponents. Please see Typical Microwave Oven Electronics Bay for parts identification. Testing the oven the water heating test The precise number of degrees a known quantity of water increases in temperature for a known time and power level is a very accurate test of the actual useful microwave power. Electro Dynamic Speakers radioremembered.org Electromagnetic Dynamic Speakers Electromagnetic dynamic speakers have a field coil that is wound on the center pole piece which is part of the speaker pot. (See Diagram) The field coil is often used as the filter choke of the receiver power supply. How PC Fans Work PCB Heaven A very common type of PC fan. These fans introduced the "tacho" for the first time. The first two wires are the power supply of the fan. The third wire, comes directly from the output of the Hall sensor.This output generates 2 pulses per one revolution of a fan. The Transistor Amplifier Talking Electronics Fig 1. NPN Transistor: Fig 1 shows an NPN transistor with the legs covering the symbol showing the name for each lead. The leads are BASE, COLLECTOR and EMITTER. The transistor shown in the photo has a metal case with a tiny tag next to the emitter lead.

Astromilitary Atomic Rockets Of those American vessels near the Argonne when first contact was made with the enemy, only the Washington was sufficiently massive to go out in a blast of yonder size and shape. If that was the case Captain Martin Diaz of the United States Astromilitary Corps was a dead man. The other ships of the line were too distant, traveling on vectors too unlike his own, for their scout boats to come ...
