Telephone In Use Relay, LM317 Regulators, Lithium Charger 2 Cell Lithium Ion Charger This circuit was build to charge a couple series Lithium cells (3.6 volts each, 1 Amp Hour capacity) installed in a portable transistor radio. Relay A relay is an electrically operated switch.Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid state relays.Relays are used where it is necessary to control a circuit by a separate low power signal, or where several circuits must be controlled by one signal. Relay SPDT Sealed COM 00100 SparkFun Electronics When the relay is off, the COM (common) pin will be connected to the NC (Normally Closed) pin. When the relay is on, the COM pin will be connected to the NO (Normally Open) pin.

Transistor A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power.It is composed of semiconductor material usually with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals. Because the controlled (output) power can be ... adding extra lights do i need relay the12volt adding extra lights do i need relay Hi I've added some extra vanity lights to use as footwell lights to my car interior's (Vw mk4 golf). Its working fine at the moment with the central locking switched ground and power but I have been advised by an experienced electrician that I MUST use a 4 5 pin Using Transistor as a Switch | ermicroblog Blog Entry Using Transistor as a Switch December 23, 2008 by rwb, under Electronics.. Most of microcontrollers work within 5 volt environment and the I O port can only handle current up to 20mA; therefore if we want to attach the microcontroller’s I O port to different voltage level circuit or to drive devices with more than 20mA; we need to use the interface circuit. wiring an accessory to ignition on power the12volt wiring an accessory to ignition on power I am trying to connect an accessory to my truck (2004 Chevy Silverado 1500) and ONLY want the thing to come on when the ignition is on. I don't want to be able to turn the thing on when the ignition is off and or key is out of the ignition. Where would be 70 Interesting Circuits Talking Electronics 12v LAMP DIMMER Here is a 12 volt @ 2 amp lamp dimmer that can be used to dim a standard 25 watt bulb by controlling the duty cycle of a astable 555 timer oscillator. Transistor 101science 1. INTRODUCTION A transistor is a small electronic device that can cause changes in a large electrical output signal by small changes in a small input signal.That is, a weak input signal can be amplified (made stronger) by a transistor. For example, very weak radio signals in the air can be picked up by a wire antenna and processed by transistor amplifiers until they are strong enough to be ... Working of Relays How Relay works,Basics,Design ... It is an electro magnetic relay with a wire coil, surrounded by an iron core. A path of very low reluctance for the magnetic flux is provided for the movable armature and also the switch point contacts. Â The movable armature is connected to the yoke which is mechanically connected to the switch point contacts. Powering Your Microcontroller’s Base Project | ermicroblog Blog Entry Powering Your Microcontroller’s Base Project February 28, 2009 by rwb, under Electronics.. A good power supply is an essential subject to the microcontroller’s base project; it’s like a heart that gives a life to our microcontroller. 5 Transistor ESR Meter Design Page 1 EEVblog Hi Forum Members, There seem to be as many ESR meter designs as people who use them. I have decided to share my ESR meter design with the group. Strictly speaking this ESR meter does not measure ESR, it measures the impedance of the capacitor under test at 100kHz. DPDT Relay Double Pole Double Throw The DPDT relay (Double Pole Double Throw) is quite interesting and can be used in various scenarious, including for changing the direction of a motor as you can see in the picture below. 101 200 Transistor Circuits Talking Electronics Kit for Transistor Circuits $15.00 A kit of components to make many of the circuits described in this eBook is available for $15.00 plus $7.00 post. Or email Colin Mitchell: talking@tpg .au The kit contains the following components: Alarms of all kind Circuits This section contains Alarm circuits of all kinds. 12 Volt Alarm Power Supply A 12 Volt power supplied designed for Ron's Modular Burglar Alarm. However, being a popular supply voltage this circuit will have many other uses as well. Installing those new relays in y Fox Tango Installing those new relays in your FT 102 . For those who have bought the FT 102 relay kits. Here are some hints to do the job. Please do not consider these to be step by step instructions, however my notes may help you do the job. New Lightning Detector for the Beginner techlib Magnetic Antenna Version. Note: The magnetic versions are more sensitive to distant lightning but they are fairly dead to piezo lighter impulses those lighters don't emit much energy at 5 kHz the way a lightning bolt does. Electronic Projects redrok Electronic Projects mostly associated with solar power. With these requirements in mind, and some others, I decided on a variation of National Semiconductors "Micro Wire"(TM). Ionization Chambers (page 1) techlib Experimenter's Ionization Chamber for quick, simple experiments.. Improved Transistor Circuit drifts much less than the single Darlington transistor circuit.. The Polonium Pen for spotting those "hot" drinks.. Nuclear War Detector save yourself a trip to the window.. Frankenstein's Dosimeter uses parts from a CDV715..

Linear versus switching supplies You all know how a typical linear power supply operates: A heavy transformer takes the line voltage and converts it into something slightly above the desired final voltage. Bally Stern PinWiki The early circuit boards were fabricated by a company called Universal Research Laboratories (URL). URL was purchased by Gary Stern as part of his strategy in acquiring the assets of the defunct Chicago Coin; it is this connection that enabled Stern to use essentially the same hardware for their solid state games as Bally.
