LED circuits are very easy to design. An LED or Light Emitting Diode, is a very low current light source that is very safe and durable for use in your project. This article will show you how to...
Before working on any motor, be sure you discharge the capacitor. Capacitors store energy and can pack a serious and potentially dangerous jolt of electricity.
Electrical resistance is the measurement used to determine the flow of electrical current and how much that flow is impeded. This is a common test used in the troubleshooting of various electronic...
An amplifier's basic purpose is to increase the frequency of the hertz produced by audio waves. There are many different types of amplifiers designed for specific purposes; however, the most...
If you need to wire LEDs for a project there are some things to know. LEDs, also known as light emitting diodes, can be very useful because of the amount of light emitted with only very little...
Diodes ensure that current flows in just one direction. Resistors control how much current flows through a circuit. Both are marked with colored stripes that mean nothing to a person who doesn't...
The job of a resistor is to help control the amount of current in an electronic device, and its value is shown in colors. The numbered reading you get when using a multimeter can be converted to...
Digital Multimeters have many functions that are useful. One of the things Digital multimeters are very capable of performing is testing components. This article will show you how to use your...
This article is about how to construct a lamp using an LED (light emitting diode). The benefits of one is that there bright and dont use much electricity so the batteries will last longer.
It is possible to make a lab power supply from the ATX power supply that you can salvage from a discarded computer. All you need is the old computer and some extra supplies. Follow these steps to...
One of the first things you'll need to understand when working with electronic circuits is how to use the correct sized resistor. It's quite simple once you understand it.
When voltage is not flowing through a circuit properly, there can be a number of reasons for the problem. There can be a break in the line, a loose connection or some other problem like a blown...
I finished a speaker building project of four surround speakers this past Spring. These are not just painted plywood boxes with cheap paper speakers. I would compare them any day to audiophile...
Simple wireless devices use various components to activate an infra-red signal that broadcasts to a receiver box, allowing the user to program the control. Basic wireless remote controls simply...
This is how to make a fairly simple and small, yet remarkably powerful strobe light.
Five basic electrical symbols tend to show up in electrical diagrams or schematics. By referring to the included image, you can match these to their definitions.
Vegetable steamers are handy appliances to have in your kitchen and can save you lots of time preparing healthy dishes for your family. Like other electrical devices, however, their wiring can...
Rice cookers are handy appliances and can save you lots of time and effort in the kitchen. Like other electrical devices, however, their circuitry tends to wear down over the years, sometimes...
Electronic circuit design can range from a simple task for the home hobbyist to a highly complex project requiring teams of designers. A simple project may not require a formal design process but...
A resistor is an electrical component that introduces resistance to a circuit by causing a drop in the voltage. A resistor is a common component in electronics and can be found in virtually all...
LED bulbs are the next big thing when it comes to flashlights. LED flashlights can cost hundreds of dollars, depending on the kind of LED bulb used. However, you can make your own ultraviolet LED...
LED, or light emitting diode, is the name of the tiny light bulbs that are commonly used in electronic devises that indicate if a device is plugged into a power source and displays the status of...
Knowing the basics of auto repair can save you thousands a year in repairs. Fixing the fan control clutch in an Intrepid (1998 to 2000)is a basic task, one you can perform without any professional...
With increasing demand for electricity especially in developing countries, electricity supply authorities are finding it hard to meet the daily demand for electricity particularly during peak...
An electric steamer can be used to steam vegetables or cook rice to perfection. The food is healthy since it is not boiled or cooked in oil. Steamers are almost fool proof, but if problems occur,...
Are you curious to see if your loved one is lying to you? Are you trying to make a cool gadget for your next party? Or are you working on a science project? This simple lie detector can be made...
Learn how a variable resistor (potentiometer) works in an electronic circuit in this free home maintenance video.

Learn how to remove a resistor soldered to a circuit board in this free video.
Learn how to solder a resistor to a circuit board in this free video.
A solenoid is basically a three-dimensional tight coil of wire. However, when a solenoid is connected to an electric current, it creates an electromagnetic field within the inside of the coil of...
Wiring LED lights can be a bit tricky, because of the accuracy demanded in circuit values and the number of LEDs in a typical lighting circuit. With LEDs, you need very accurate values for...
An invisible mask is not really a mask, and not quite invisible. Basically, it is a device which uses high intensity infrared LEDs implanted in a hat to blind cameras. If a person looks at the...
A capacitor usually consists of two conductors placed close to each other. It stores electrical charge in units that are called a farad. Common capacitor values typically range from picofarads to...
Want to "blow away" the typical birthday, graduation, retirement, holiday cake... Try this LED cake. It will impress even the most jaded guest with its circuitry, brightness and...
Ink cartridges are the key component to any printer, and the only consistently replaceable component. Ink cartridges contain the ink that is put onto the paper during the process of printing. Some...
Like a lot of electronic equipment, motion detectors are simple in their concept. They detect changes in the nearby environment, such as a shift in the heat signature when a person enters the room...
The electric skillet works in more or less the same way an electric heater or hair dryer works. A high-voltage electric current is run through a resistor. The resistor resists the flow of...
One of the biggest problems with electric motors is electric batteries. There are plenty of powerful, fairly efficient and dependable electric motors out there, but batteries simply aren't up to...
Many people are searching for renewable sources of energy. Using alternative energy is good for the environment and can also reduce your dependence on public utility companies, who often charge...
Solar energy gains in popularity each year. The sun provides us with power that is not just renewable, but is also clean and efficient. The best part is that it is free, aside from the initial...
Traditionally, thermostats have been powered by a thermometer coil. A thermometer coil is made of a bimetallic strip, two metals attached side by side and looped around in a coil. When the...
Building a remote control can be an exciting way to learn about basic electrical components. A simple remote control uses infrared signals to tell a receiver box to do something. The most basic...
Power from the battery flows into the steering column, where it enters the turn signal switch. The switch has 3 positions: off, left and right. When a left or right turn is indicated, the...
