By Phillip Torrone LED throwies made their first appearance and were popularized and developed by the Graffiti Research Lab a division of the Eyebeam R&D OpenLab in February 2006 (Wikipedia page). It's also in Make - Volume 06 - LED Throwies (Page 116).

By Brian Lam Most of this does not concern me, or move me to object in any way to LED lightbulbs, as much as the thought of LED light itself, so alien, in my house. In wikipedia, we get a description, under the disadvantages of the problems of white LEDs that "spike at 460 nm and dip at 500 nm," causing objects...

What happens when you throw in 120 LEDs, NerdKit, Python and an appropriate Google Voice module? Well, throw in some technical know how and you end up with a voice controlled LED sign. For instance, leaving a voicemail on the recipient's Google Voice account by starting with “message”, an...

By Marc de Vinck Instructables user 'computergeek' sent in this Arduino Charlieplexing tutorial. It's a great technique for controlling a lot of LEDs without having to use up all your I/O pins. In this example, only 4 pins are used to control 12 LEDs.

By jakeselectronics So, 0-99mA will light 1 LED. 100-199mA will light 2 LED's and so on. I was thinking of using the LM3914 to drive the LED's, but this means I need to convert the Current to a Voltage. So, I was thinking of using this part; ASC712 Hall Effect Current Sensor

By Brian Lam Bravia Internet Widgets, powered by the Yahoo! Widget Engine, also expand and personalize the TV experience by adding on-screen applications that provide such information as weather reports, stock information, financial news, Twitter, and additional content.

By Drunk Dumbass I have a 12 volt, 10 LED light that I would like to hook up to a battery & solar charger with a photocell switch so that the light will come on at night and shut off during the day. The current draw for the light is .08 Amps. So 12 volts X .08 Amps = .96 Watts

By Brian Lam Sony's engineers went to remarkable lengths to create it, almost as if the ghost of Sony's founding fathers came down and rekindled the engineering pride of the company, telling them to spare no measure to create the TV. "Use LEDs! Use three or four of them for every one those bastards in Kor...

By tdg8934 Lighting and Display Solutions - LED Drivers - TLC59116 - TI.com I am concerned that this chip can only connect up to (14) I2C TLC59116 chips. That is only 14 X 16 outputs or 224 LEDs. How would I get around this? I need to have 1000's of LEDs in 16x8 modules driven by a 'smart' PWM LED driver.

By Marc de Vinck This week I am going to be making the Open Heart kit by Jimmie Rodgers. It's a great open source kit that uses a technique called Charliplexing for lighting up the LEDs. Why? Charlieplexing allows you to control each LED's state individually. All you need to do is create a simple program and upl...

By Leo Hickman The packaging should always tell you the equivalent wattage of the bulb. In general terms, CFLs use 65-80% less power than an incandescent bulb. Therefore, a CFL marked as "100W" could need as little as 20 watts of power. There are even some newer bulbs that use LED (light emitting diode) tech...

By R2-D2 Can I use just one resistor for each group of LEDs (R7, R8 and R9) instead of one for each of the six branches in the LED groups? If I need a resistor for each branch (of three LEDs), I have calculated them to be at 75Ω each. R = (1.8 volts dropped / 0.024 Amps) = 75Ω

By Wilson Rothman LED backlighting is the wave of the future for LCDs, and not just because they are "greener" than the current CCFLs. Because they can alternately dim and brighten 60 or 70 separate clusters of LEDs underneath the LCD panel, you get deeper contrast, but without losing detail in dark scenes. T...

By Cisco Cheng While the overall design remains virtually unchanged, there is one really exciting improvement, and that's the use of LED backlights on the 15-inch Macbook Pros.
