By Ally These hurricane lamps are made out of plastic and stand 4” tall.  The light within the lamp can change colors, it flips between a total of 7 different colors.  The light uses LED bulbs, so it won’t require too much power to keep it going.  It of course just requires you to plug it into your USB port...

By Collin Cunningham I did manage to achieve (with a liquid dielectric) voltage and current gain, as well as construct a functional astable oscillator using two of the devices constructed on a single substrate. While the speed of the devices (due to the liquid dielectric) is such that they are only interestin...

“Nope, and since this here gem provides up to 10 hours of continuous light on a full charge and has LED bulb that never needs replacin’, I’d say you’re not going anywhere any time soon, hero. Hey, Jimmy! Guido! Get in here and get this scumbag, will ya?”

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...

We all hate power outages, especially it more often that not means that the Internet and computers will be down. That being said, it’s nice to know that a landline phone will still work even when the power is down, and that idea has resulted in the creation of the 8 LED desktop lamp, featuring a...

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 jeno2 I try to build an auxiliary LED brake light driver to my bike using a basic 555 astable circuit. I want it to flash 3-4 times in the first second when the brake applied then hold a steady light until I release the brake. Any idea how to achive this?:confused:

By solis365 A basic schematic is attached, with current limiting resistors just as place holders. (I had to use a really basic online editor for this one; the circles are LEDs.

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 khowell So and his team’s blue OLED achieved a peak efficiency of 50 lumens — a lumen is a measure of brightness perceived by human eyes — per watt. That’s a significant step toward the goal of his project: to achieve white light with efficiency higher than 100 lumens per watt.
