Voltage Dividers learn.sparkfun Introduction. A voltage divider is a simple circuit which turns a large voltage into a smaller one. Using just two series resistors and an input voltage, we can create an output voltage that is a fraction of the input. Voltage dividers are one of the most fundamental circuits in electronics. Potentiometer Working, Their Applications and Different Types The Potentiometer is an electric instrument that used to measure the EMF (electro motive force) of a given cell, the internal resistance of a cell. And also it is used to compare EMFs of different cells. It can also use as a variable resistor in most of the applications.

Voltage Controlled Oscillator (VCO) The voltage controlled oscillator (VCO) in the NOISE TOASTER provides a nice wide range of frequency and two waveforms (ramp and square). FM Transmitter with Varactor Diode Tuning Electronics DIY Presented here is a low power FM transmitter with varactor diode tuning using surface mount devices (SMD) that will be received with a standard FM radio. Soldering surface mounted devices is not so hard and actually is quite easy. There are many designs for small FM transmitters but they have some problems. First, you need an audio amplifier to get enough modulation. Voltage Controlled AC Light Dimmer PCB Heaven The first thing that comes to someone's mind when thinks of a dimmer, is a potentiometer that controls the light intensity. If a potentiometer is used, things can be very easy. Thermostat Controller with Relay using LM35 and TL431 Here is a simple yet highly accurate thermal control circuit which can be used in applications where automatic temperature control is needed. The circuit switches a miniature relay ON or OFF according to the temperature detected by the single chip temperature sensor LM35DZ. When the LM35DZ detects a temperature higher than the preset level (set by VR1), the relay is actuated. 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. GPS Locked Frequency Standard techlib GPS Locked Frequency Standard (Excessively Simple) Imagine that one day you wake up to learn that all the GPS satellites have been destroyed. What's happening? Modifying a Chinese power supply to provide a variable voltage After this page was posted on Hackaday, a commenter pointed out that 7.5V is actually a standard power supply voltage! I never knew this, so I was only searching for 5V, 12V, 24V supplies. Sure enough, there are lots of 7.5V supplies around for example TRC Electronics.In addition, most of these will have ±5% adjustment so, for the original application which required 7.4V, I could just have ... The Emperor's New Amplifier Norman Koren I spent much of 1997 designing and building my ultimate dream amplifier, which I named "The Emperor's New Amplifier" TM (TENA) for a quality it shares with the fabled emperor's wardrobe transparency. It was also an oblique reference to the marketing hype that pollutes high end audio. Wheatstone bridge A Wheatstone bridge is an electrical circuit used to measure an unknown electrical resistance by balancing two legs of a bridge circuit, one leg of which includes the unknown component.The primary benefit of the circuit is its ability to provide extremely accurate measurements (in contrast with something like a simple voltage divider). Its operation is similar to the original potentiometer. Interfacing 20x4 LCD With Arduino: 5 Steps Interfacing 20x4 LCD With Arduino: A liquid crystal display (LCD) is a flat panel display, electronic visual display, or video display that uses the light modulating properties of liquid crystals. Liquid crystals do not emit light directly. Here, in this i'ble we're going to use a ... LED Fade In Fade Out Dimmer PCB Heaven Here is the first circuit schematic that i designed, and i tried to keep it as simple as possible: Similar to the LED fade out dimmer, multiple LEDs can be connected in parallel with one resister per node.Again, you need to take into account the maximum ratings of the transistor before connecting a million LEDs. Adding Digital Metering to Astron 14V Linear Power Supplies After reviewing the data above, it's obvious that the SL 15 and RS 20 really should be using two 0.05 Ohm resistors to keep the power dissipation below 5 Watts per resistor; this is just one of the many design errors and inconsistencies present in Astron's linear power supply products.

The primary difference between the two kits is the microcontroller included in the kit. The SparkFun Inventor's Kit includes a SparkFun RedBoard, while the SparkFun Inventor's Kit for Arduino Uno includes an Arduino Uno R3.At the heart of each is the ATmega328p microcontroller, giving both the same functionality underneath the hood. The Long Tail Pair Aiken Amps The Long Tail Pair. General. The Marshall Fender phase inverter is commonly known as a "long tail pair", or "Schmitt" type phase inverter, or phase splitter (actually, the original Schmitt inverter was a differential pair with a large "tail" resistor; the "standard" guitar amplifier phase inverter is a self biased version of this circuit that works better with positive only power supplies and ... RIAA Equalization Beige Bag This reverse equalization (de emphasis equalization) can be performed in either an active or passive fashion. The active method works by selectively varying the amount of output signal given to the preamp's negative feedback input (in relation to frequency). Operational amplifier An operational amplifier (often op amp or opamp) is a DC coupled high gain electronic voltage amplifier with a differential input and, usually, a single ended output. In this configuration, an op amp produces an output potential (relative to circuit ground) that is typically hundreds of thousands of times larger than the potential difference between its input terminals. ElectroSmash Klon Cenatur Analysis Klon Centaur Analysis. The Klon Centaur in an overdrive guitar pedal designed by Bill Finnegan with the help of 2 MIT Electronic Engineers between 1990 and 1994. The initial idea was to improve the TubeScreamer transient response and the midrange bass frequencies in order to create a big open sound with a hint of tube clipping: the so called transparent overdrive. Build a USB Powered AA NiMH and NiCd Battery Charger During charging, R1, R2, and R4 form a three way voltage divider which yields about 1.26V at the non inverting input of Z1a (pin 3, Vref).
