To simplify incandescent-like LED dimming – where colour temperature (CCT) falls with intensity – Dialog Semi has introduced a single chip dual output power converter that needs no microcontroller. iW3640 is a 25W 2-channel mains-powered LED driver, intended for 75-150W-equivalent A19 and PAR bulbs, as well as 20-45W commercial dimmable external lighting ballasts. It works

Overview This project is a HVPSU (High-Voltage Power Supply) that generates up to 220V from a 12V input. In addition to that, it also provides 2*Vout (so, up to 440V, for dekatrons), and two outputs for powering digital logic: 5V and 3.3V. The primary HV boost circuit reaches 88% efficiency when going from 12V to

EnOcean has introduced its first energy harvesting wireless switch module for consumer applications such as the control of LED lighting systems. The device which operates in the 2.4GHz ISM band, has a form factor which allows it to fit in a standard light switch. The device’s electromechanical energy generator converts kinetic energy into electrical energy which is used to power to a

By coupling a standard NMEA GPS receiver and an Arduino board we created a super simple and effective Arduino GPS logger. This device allows you to trace the route taken by a person or vehicle (or any other moving object) by simply doing a periodic caching of location points coming from the GPS unit. As
