A LED light pipe is an optical fiber or a solid transparent plastic rod for transmitting light from an LED mounted on a printed circuit board (PCB) to the user interface. Light pipes transmit up to 80 ...

Using a bunch of WS2812B led chipset I build a net of lighting for my jumper, this is the first version so do not expect too much from it, version 2 is on it's way. I designed the small pcb to use the ...

In this project, I'll make a small circuit capable of blinking lights, on its output we get a digital signal that we can use to turn on and off an external light like an led or relay for bigger loads.

Osram Opto Semiconductors was able to sink a surface-mountable infrared (IR) LED into a printed-circuit board, creating what it claims is the first the first flush-mountable version of its kind. The ...

This clock looks fantastic because of the glass PCB used for the build. This banner image allows you to see all the traces and components, but when it is lifted off of the desk surface the LEDs which ...

[Johannes Agricola] recently held a workshop at the Peace Mission in Goettingen, Germany where he shared his RGB LED flowers. The small round PCB hosts an ATmega88 microcontroller which is running the ...

The folks at Alpine Electronics asked if I’d like to take apart their LED tube light which is intended as a replacement light for fluorescent lighting. Who could resist an offer like that? Alpine sent ...
