Inspired by printed circuit boards, the building block of all electronics, a Dutch designer has created an LED-based light installation that draws upon the familiar etching pattern inside most devices ...

Frank Hertel’s project: three individually dimmable LED lights. (Frank is the master of recycling; the wooden mounting pedestals are the panels from a decommissioned ATI console!) Thanks for your ...

Light-emitting diodes are often used with a voltage source from a power-supply output voltage. The output voltage increases until the current through the LEDs reaches the value of the constant-current ...

We’ve got a thing for projects that have no real practical value but instead seek to answer a simple yet fundamental question: I wonder if I can do that? This dead-bug style 555 blinky light is one of ...

A new AI chip powered by light, not electricity, delivers massive energy savings while matching conventional performance. A group of engineers has created a breakthrough computer chip that relies on l ...

Teardowns of cheap electronic devices can produce results that are interesting, horrifying, or both, especially when mains power is involved. [bigclivedotcom] gave a minimalist LED lamp his reverse ...

Even if you are designing a microcontroller-based LED display system, often it may calls for a manual option to control brightness of the LED display unit. On the otherhand, if it is based on discrete ...

British scientists are claiming a breakthrough that promises to unite microelectronics with fibre optics and bring about an upheaval in microprocessor manufacturing and modern communications.

Need a pulse stretcher for an application like an LED flash? James Campbell does it using TI's configurable multifunction logic gate. A recent design project required ...

TESS, a Taiwanese manufacturing company, recently introduced a 7W LED bulb that, at 560 lumens, can serve as a replacement for a typical 500-lumen, 40W incandescent bulb (Figure 1). TESS has received ...
