Chances are, you still own a TV that is bulky, has a picture tube and is kept on a table. Well, with advancing technology, TVs have become slimmer and lighter, can hang on the wall and do not have a bulky picture tube.
The new TVs have an LCD or a Liquid Crystal Display in place of the earlier picture tube. Now, unlike the picture tube, LCDs have no light of their own, and have to be lit with a backlight. Until recently, most LCD TVs were backlit with plasma discharge tubes or CCFL lamps.

This is an amazingly handy little light - thin enough to use on your house key or car key. Think of it as a stick-on LED! The Thumb-Lite’s compact design makes it easy to turn anything into a flashlight. Whether you use it for unlocking a car door or finding something dropped in the dark, the Thumb-lite is a convenient way to provide extra light when needed.
What makes this stand out from the other tiny LED lights is that the Thumb-lite can be used effortlessly with one hand. Pressing the button Read more [...]
We love finding products that make great use of solar electricity and our electronic components. How about a solar powered LED light in a mason jar? Perfect for your backyard porch or for mood lighting at a party - or even as a night light in your bathroom, bedroom or kitchen!
The ones we found at MyGrillfriend.com give you a choice - it can be a soft deep orange colored light (referred to as a 'sun jar') or a beautiful shade of blue (called a 'moon jar') just by flipping a switch. The solar panel Read more [...]
West Florida Components was recently invited to participate in a science experiments fair held in conjunction with the USF Education Department.
Each business staffed a booth where elementary school aged kids along with their families could conduct science experiments. The community event was an opportunity for families to enjoy and see the benefits of science in a fun atmosphere. The West Florida Components station was one of about 18 stations at which participants could interact and have Read more [...]
Here's an easy project that simple enough for electronic beginners, plus the supplies required are probably laying around your house or workshop.
Could you buy the same thing for just a few dollars more? Sure you could, but you'd miss out on the satisfaction of assembling this project all by yourself.
Here's what you need:
2 high intensity white LEDS (you can use other colors if desired)
small perf board
2 470 ohm resistors
toggle switch or slide switch
9V battery snap
small Read more [...]
Applied Materials announced this week that it was planning a major restructuring of it's business. The goal? To place a "primary emphasis" on LEDS and crystalline silicon solar panel technology.
This restructuring would effect the bottom line of the company in many ways including the elimination of 400 - 500 jobs and the closing of their thin-film solar technology lab among other plans.
The future of Applied Material's solar technology would focus on the crystalline silicon solar product development Read more [...]
Here are more questions we get asked a lot:
What is the positive (or negative) lead on an LED? How do you determine the polarity of an LED?
If you are talking about through hole LEDS, in most cases it's pretty easy to determine the polarity.
If the LED has two leads, one longer than the other,the longer lead is the postive (also known as the anode) lead.
If the LED has two leads with leads that are equal in length, you can look at the metal plate inside the LED. The smaller plate indicates Read more [...]
West Florida Components has just started to carry an exciting new product - RGB Tricolor Flashing LEDS!
At first glance you might think "Why are they calling them both RGB AND Tricolor?" The reason is that each LED is actually 3 separate LEDS housed in one case.
They operated in a sequence: first one color is lit at a time, then two light up, then all three. The cycle is completed when all three LEDS have been lit slowly, then begin to flash. Max voltage is around 3V.
Here's a demonstration Read more [...]
7 Segment LEDs or 7 segment displays are a type of electronic display devices used for displaying decimal numbers, in place of the more complicated dot matrix displays. 7 segment LEDs are used in a number of applications such as electronic meters, digital clocks and other such electronic devices.
As the name suggests, these electronic components are made up from 7 segments that are used for displaying each of the numerals from 0 to 9. The segments are arranged in a rectangle pattern with two Read more [...]
What is Infrared?
The electromagnetic spectrum has waves of various wavelengths. Human eyes are capable to seeing the light that form a small part of electro magnetic spectrum. The waves with shorter wavelength as well are longer wavelengths than the visible spectrum are not visible. Infrared are waves that have longer wavelengths than the visible spectrum. The wavelengths corresponding to the Infrared waves are in between 750nm to 1mm.
Infrared waves cannot be seen but can be felt in the Read more [...]
