5″ capacitive touch panel with GSL1680 up’n running with arduino

Electronics News Updates / By

Some months ago I wrote about getting a 7″ capacitive touch LCD up’n running with Arduino. Since that time I’ve investigated 5″ displays with capacitive touch. There are some, such as the NHD-5.0-800480TF-ATXL#-CTP from Newhaven which uses the FT5306 capacitive touch controller. That one is interesting because I already have touch driver for the FT5x06 […]

Relay Finder2

Relay Finder will let you know, when one phase is missing …

Electronics News Updates / By

Finder monitoring relays are able to effectively signalize a fault status in a mains line and to prevent damages or undue wear-out. Too high or too low voltage, phase loss or a wrong phase rotation are conditions commonly occurring in an industrial environment. Even though a phase rotation is usually stable, but only one improperly

High Efficiency 140V 400mA Step Down Regulator

LTC7138 – High Efficiency, 140V 400mA Step-Down Regulator

Electronics News Updates / By

Description The LTC®7138 is a high efficiency step-down DC/DC regulator with internal power switch that draws only 12μA typical DC supply current while maintaining a regulated output voltage at no load. The LTC7138 can supply up to 400mA load current and features a programmable peak current limit that provides a simple method for optimizing efficiency

60V Synchronous Step Down High Current LED Driver

Design Notes: 60V, Synchronous Step-Down High Current LED Driver

Electronics News Updates / By

Introduction The meaning of the term “high power LED” is rapidly evolving. Although a 350mA LED could easily earn the stamp of “high power” a few years ago, it could not hold a candle to the 20A LEDs or the 40A laser diodes of today. High power LEDs are now used in DLP projectors, surgical equipment,

1st MEMS Spectrometer Debuts

Electronics News Updates / By

PORTLAND, Ore. — The world’s first microelectromechanical system (MEMS) spectrometer on-a-chip was shown today at at Photonics West (San Francisco, February 10-12) by Si-Ware Systems (SWS, Cairo, Egypt with offices in La Canada, Calif.) Instead of transporting materials across sometimes great distances to be analyzed with a normal bench-top spectrometer, Si-Ware’s MEMS-powered spectrometer fits in
