Voltage Testers

Today’s EIO post is on Voltage Testers:

Making electrical repairs in your home can save you hundreds of dollars in service costs. One tool you’ll need to get started is a voltage tester. If you have a voltage tester, you can test outlets and light switches to see if voltage is present in their circuits. The most basic type of voltage tester consists of a small, pen-like device with a red lead and black lead extending from it.

What is a Voltage Meter?

    • A voltage meter is a device that is used to measure the strength of an electrical current flowing within an electrical circuit. Essentially what it does is measure the electrical potential (the strength of an electrical charge) at two specific points within the circuit. It then compares these potentials and presents the difference between the two. This difference is the rate at which current florws through the circuit. Voltage meters can be analog devices which use an arrow to indicate the electrical potential, while digital ones provide a read-out.

    Structure

    • At the center of the voltage meter is a magnet connected at both ends to pieces of magnetized iron. Sitting between the ends of the magnet is a cylinder made of iron. Because of its placement, the cylinder sits within both the positive and negative fields put out by the magnet. A coil of copper wire is wrapped around the far end of the cylinder, all of which is fitted into a housing. At the far end of the wire is a needle, steadied on either side by a spring. Behind the needle is the dial representing voltage. Fitted on the outside of the housing are two more wires, each of which connects to either end of the magnet.

    How Does a Voltage Meter Work?

    • When the voltage meter is at rest, the needle points to the left side of the meter, representing zero electrical potential. The wire leads are attached to two parts of a live circuit. This causes the electricity to polarize the magnet within the meter even further. Should the difference of the potential between the two wires be a positive number, which it would be if any electricity were flowing through the circuit at all, the magnetic field within the meter becomes positively imbalanced, causing the needle to pull from the left side of the meter to the right, indicating how strong the electrical potential is.

Today’s EIO post is on car electronics and the different products related to rear view cameras for automobiles.

What are Backup Cameras:

A backup camera is a special type of video camera that is produced specifically for the purpose of being attached to the rear of a vehicle to aid in backing up. Backup cameras are alternatively known as ‘reversing cameras’ or ‘rear view cameras’.

The design of a backup camera is distinct from other cameras in that the image is horizontally flipped so that the output is a mirror image. This is necessary because the camera and the driver face opposite directions, and without it, the camera’s right would be on the driver’s left and vice versa. A mirrored image makes the orientation of the display consistent with the physical mirrors installed on the vehicle. A backup camera typically sports a wide-angle or fisheye lens. While such a lens spoils the camera’s ability to see faraway objects, it allows the camera to see an uninterrupted horizontal path from one rear corner to the other. The camera is typically pointed on a downward angle, to view potential obstacles on the ground as well as the position of approaching walls and docks, rather than straight back.

Today’s EIO post is on Light-Emitting Diode (LED) Displays.

LED

If you are uncertain about the basic qualities and uses of LED’s, please refer to this earlier post providing a basic summation.

7-Segment LED Displays

Seven segment LED displays are the most basic representational format used to create an electronic image or representation.  They are composed of seven congruent parts, which can be manipulated to create the Arabic numerals (0-9) as well as the six letter digits (A-F).  The most common uses for seven segment displays are for posters, electronic telephone number displays, and pricing displays. Seven segment displays are no longer used as frequently as they were in the past, due to the fact that dot-matrix displays are now the common display method utilized to take full advantage of LED capabilities.

QT Optoelectronics MAN6460 Single Digit LED Display

Dot Matrix Displays

Dot matrix displays are now the most common form used to create images and representations with LED’s.  Dot matrices consist of a 2-D matrix of LED’s.  Through the flow of electricity, it is possible to control each LED individually, which allows for the creation of different objects and symbols.

Today’s Eio post is on flashlights.

Flashlight overview

Flashlights are common household objects. It is a hand-held portable light source that is usually powered by batteries. The light source usually comes from a light-emitting diode (LED) or an incandescent light bulb.

Wisegeek lays out the differences between incandescent flashlights and LED flashlights:

Incandescent light used in traditional flashlights utilizes a filament wire encased in a glass vacuum tube or bulb. When electricity is supplied to the wire from the batteries, the wire glows with heat that produces light. The heat, however, is not only lost energy but it eventually burns out the wire and the bulb must be replaced.

A LED flashlight harnesses light created by an entirely different process. Two types of semiconductor materials are used in a LED: one type that has an abundance of free electrons and the other that has a deficit. When enough energy is supplied in the form of electricity, a threshold is reached that pushes some of the free electrons in the abundant material to jump to the attracting material. When that electron takes its place in the new material a photon or particle of light is released.

Special Uses

Some forms of the flashlight have been adapted to meet special uses.

Headlamps

Headlamps, or flashlights built into head-bands or helmet mounted, give one light when their hands are full. These are especially useful for miners, campers, mechanics, or other jobs that require hand-free environments. Here are a few examples on our Eio website:

VELLEMAN ZLHL389 MINI LED + HALOGEN HEADLAMP

This product is powered by 3 white LED bulbs. The LED has a long-life of 100,000 hours. It comes with adjustable headband, up/down adjustable headlight, has a focus control from spot to floodlight, and has three modes: 2 LEDs on, 3 LEDs on, or halogen lights on.

VELLEMAN ZLHL510 ULTRABRIGHT LED HEADLIGHT WITH CLIP

This headlamp can be worn both on one’s head, wrist, or clipped to the front of the shirt. The LED has long-life and is ultrabright, has a focal lens, and has an adjustable and removable headband with fixing clip.

Large Flashlights

Large flashlights generally come with bigger batteries, bigger light bulbs, and more power. They are able to project light brighter, farther, and wider than other flashlights. For instance, some are used for deep sea diving to see in the murky depths of the ocean. These are often waterproof as well.

Pelican 4100B

This productis submersible to 500 feet (150 meters) as it is the diving version of the King PelicanLite™. Features include a dual filament Xenon back-up safety lamp, operating during 30 hours each filament (60 hours in total). It includes a patented shock absorbing internal battery module that protects 8-D cells Alkaline batteries (not included) from hard abuse.

Inspection Flashlights

Inspection flashlights are used to search or inspect in small, tight spaces that normal straight necked flashlights cannot reach. These often have bendable goosenecks to get light at different angles.

VELLEMAN ZL2711 ALUMINIUM ADJUSTABLE GOOSENECK CLIPLIGHT – LED 1W

This gooseneck flashlight dimensions has 12.60″ gooseneck length with collimator which provides more focused beam distribution. It provides momentary or constant illumination and its DC-DC regulator maintains maximum light output throughout the entire battery life. It comes with clip attachment and has battery life of 2.5 hours.

Mechanical Power

Mechanical powered flashlights use a crank or winding tool that is connected to a small electrical generator. The more you crank or spin the tool, the more electricity gets generated by the tiny generator within the flashlight. This type of light is optimal when there is a natural disaster or other crisis when one finds themselves without electrical power and without backup batteries in hand.

VELLEMAN ZL388/5 DYNAMO LED FLASHLIGHT / CHARGER FOR MOBILE PHONE / ALARM / FAKE MONEY DETECTOR

This flashlight comes with mobile phone charger, flashing warning light with alarm and counterfeit money detector. Rotating the crank for 1 minute will give up to 30 minutes of continuous light. For charging your mobile phone (one adapter included): 3 minutes of cranking will give you up to 2-8 min. of talk time and 20 – 50 minutes of standby time. It has a 5VDC or 8VDC output, and the recommended rotation speed for recharging: 120 RPM, 1W output power.
