EE and firmware developer [Enrico] had played with LEDs as a kid, burning out his fair share of them by applying too much current. With the benefit of his firmware chops, he set about creating a ...

Almost a month ago I started trying to reverse engineer an inexpensive LED color changing light bulb. With your help I’ve mapped out the circuit, and taken control of the bulb. But there’s ...

With a properly sized 15VDC supply and heatsink for the D718, you could power several LED fixtures with just one dimmer. Alternately, the circuit is small enough that you could mount several dimmers ...

As soon as I applied LED power, the brightness blinded me — much brighter than the original T20 fluorescent tube, so I knew immediately that a dimmer control was required ... not completely remove ...

Manufacturers now offer autonomous and semi-autonomous light control systems that place ambient light sensors in individual luminaires and even LED-based replacement lamps ... by light flicker on an ...
