RS-232 Laser Transceiver - Laser based projects used to be
expensive, until the development of solid state lasers. This project
is designed for the entry level laser experimenter. The circuit allows any
two computers with serial (RS-232) communication capability to communicate
over 200 meters using a laser beam. A low cost transmitter only circuit is
also presented here for use in one way communication and other laser based
projects. ….(circuit / schematic design added 6/06)
Single FET controls LED array - 04/12/01 EDN-Design Ideas....White-LED
backlights are gaining acceptance because they offer higher reliability and simpler
drive circuitry than backlights based on CCFL (cold-cathode-fluorescent-lamp] and EL
(electroluminescent] technology. As a result, white-LED backlights are increasingly
common in PDAs (personal digital assistants], cell phones, digital cameras, and other
portable devices. A design.... [Design Idea by Len Sherman, Maxim Integrated Products,
