The ADP2384 is a synchronous step-down, dc-to-dc regulator with an integrated 44 mΩ, high-side power MOSFET and an 11.6 mΩ, synchronous rectifier MOSFET to provide a high efficiency solution in a compact 4 mm × 4 mm LFCSP package. This device uses a peak current mode, constant frequency pulse-width-modulation (PWM) control scheme for excellent stability […]

Silicon Labs have introduced a tiny 3 mm square hybrid TV tuner chip which supports reception of all worldwide terrestrial and cable TV transmission standards. According to its preliminary data sheet its design eliminates the need for an external balun, LNAs, SAW filters, and inductive power supply filtering. Some competing TV tuner solutions also eliminate the

Today’s tutorial is a bit different: I’m going to show you how to make your ethernet shield wireless! You can find many Wi-fi shields for Arduino: starting from the official one, up to shields based on Microchip’s ICs.] Sometimes however it could be easier (and maybe cheaper!) to connect an Arduino to the Wi-fi network using your
I belong to a village of Odisha, India where frequent power cut is very common. It hampers the life of every one. During my childhood days continuing studies after dusk was a real challenge. Due to this problem I designed a solar system for my home on a experimental basis. I used a solar panel
I would like to introduce you to one of my interesting projects. It is a wireless thermometer that measures the indoor and outdoor temperature. The device consists of two parts. One is a transmitter that contains one digital temperature sensor and a transmitter module. A second receiver consisting of an LCD screen, the analog sensor
