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. Triac Principles and Circuits — Part 1 | Nuts & Volts Magazine A triac is a controllable medium to high power semi latching solid state AC power switch. This two part article explains its basic operation and shows various ways of using it. Most of the practical circuits show two sets of component values for use with normal domestic commercial 50Hz or 60Hz AC ... Electronic Circuit Schematics Electronic Circuit Schematics. Note that all these links are external and we cannot provide support on the circuits or offer any guarantees to their accuracy. 50 555 Circuits Talking Electronics THE POWER SUPPLY Sometimes you will see a circuit as shown in the first diagram with 12v or 12v on the top rail and 0v or a negative sign or the word "negative" on the bottom rail. In this case the word negative means earth or "chassis of a car" and we commonly refer to this as "negative earth" or "negative chassis." In the second diagram, the output from a power supply has a positive 12 ... Electronic Circuits and Radio Control Gadgets, by VA3AVR Circuits Archive Older circuits. Most are working, some are not.

Radio Shack Partnumbers For the most common parts Resistor Value Calculator By Danny Goodman, AE9F Data Sheet Pin outs for a variety of other components TUP TUN DUS DUG Elektor Elektuur's Substitute system Various Schematics and Diagrams Don Klipstein Back to Sam's Schematic Collection Table of Contents. Adjustable High Voltage Power Supply This circuit uses a pair of 555 timers to provide variable frequency variable pulse width drive to an inverter using a flyback transformer salvaged from a black and white or color TV or computer monitor. Voltage regulator A voltage regulator is a system designed to automatically maintain a constant voltage level. A voltage regulator may use a simple feed forward design or may include negative feedback.It may use an electromechanical mechanism, or electronic components.Depending on the design, it may be used to regulate one or more AC or DC voltages.. Electronic voltage regulators are found in devices such as ... 40 AVR GCC Win AVR Projects. 40 projects with Atmel's AVR range of microcontollers in GCC. Last Top Next. Prev Top Next. Introduction (to my website). On this website I present all my projects with the AVR range of microcontrollers from Atmel.I like this microcontroller a lot because it of it's easy to use architecture and because there are lots of open source development tools available. Very Simple PWM With 555...Modulate Every Thing: 5 Steps Pulse width modulation (PWM) of a signal or power source involves the modulation of its duty cycle, to either convey information over a communications channel or control the amount of power sent to a load.The simplest way to generate a PWM signal is the intersective method, which requires only a sawtooth or a triangle waveform (easily generated using a simple oscillator) and a comparator. Potentiometer A potentiometer is a three terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.. The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the ... Parallel port output ePanorama.net | Audio | Video This Data Register is simply used for outputting data on the Parallel Port's data lines (Pins 2 9). If your port is bi directional, you can receive data on this address. Controllable Power Outlet SparkFun Electronics In this tutorial we will discuss a small relay board to control the power to a normal AC outlet using 5VDC control. You can get the Eagle files for the control board here. The control board is composed of a relay along with a NPN transistor and LED. What's a relay? I admit, I really just wanted to ...
