With its APM-16D17-05-DF8-TR8 and APM-16D17-06-DF8-TR8 ambient light and proximity sensors, Everlight aims to save energy and reduce unwanted signals and noises when used in smartphones, tablet PCs, residential smart lighting and digital signage applications. [via] Both series use a...

A Smart Night Lamp for kids. Tutorial and source code available: Few weeks ago I heard my nephew (aged 7) complaining of the dark at night. Basically he was afraid. So I decided to put knowledge into practice and build a night lamp for kids. Since the project was intended for kids, I...

Jan Buiting @ elektormagazine.com discuss about a new technique used by scientist to build better LEDs. By manipulating the incident light, researchers of the Complex Photonics Group at University of Twente in Enschede, The Netherlands, have turned light propagating in a layer of...

diy_bloke @ instructables.com has build an arduino controlled triac light dimmer and describes the circuit and software used to achieve that. It becomes a bit more tricky if one wants to dim a mains AC lamp with an arduino: just limiting the current through e.g. a transistor is not...

Lukas Fassler has published a new project, a DIY PWM dimmer for LED lighting. The dimmer can handle 100W@12V and is controlled by a single potentiometer. I have recently moved to a new penthouse and was looking for a PWM dimmer to control some 12V LED strips. I thought that should be...
