By ke5frf I concluded it MUST be a bad diode because it was from 5 volt bus to ground bus across all 15 RED LEDs, and the suspect LED was the only one showing an odd voltage (3.1 volts instead of 4) Knowing that CMOS logic requires a threshold voltage to change states, I figured the CPU wasn't happy with 3.1 v...

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 matt buchanan LEDs (light emitting diodes) are different from say, an old school incandescent bulb, which heats up a filament to generate light, in that they're electroluminescent—electricity passes through a semiconductor and the movement of the electrons just lights it up. Instead of having one...

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...
