A Serial Infrared Remote Controller - This is a simple, cheap device that can be connected to any serial port to control most components that have infrared remote controls. I designed and built it (on a solderless breadboard) in 1991. in 1992 I wrote a lengthy description of it for an electronics class. in 1994 I finally designed a PC board for it, using a free, X-based PC board design program called pcb, and in 1995 I etched several of the boards and made the final product __ Designed by John DuBois AC power Monitor uses remote sensing - 04/26/01 EDN Design Ideas: The detection circuit in the Design ideas - "Circuit monitors ac-power loss" (EDN , Nov 24, 1999, pg 172) requires a physical connection with the mains to sense the power loss. The circuit in Figure 1 senses the power loss through the radiated power-line signal Design by Sanjay R Chendvankar, Tata Institute of Fundamental Research, Colaba, Mumbai, India

Battery-operated remote-temperature sensor drives 4- to 20-mA current loop - 12/17/04 EDN Design Ideas: You can remotely measure temperature using a 4- to 20-mA current loop as long as 4000 feet and a battery-powered, white-light LED driver. You usually configure this equipment to provide a programmable, constant current to an LED from a battery source. The TPS62300 series of IC s, for example, converts a battery voltage of 2 Design by Scot Lester, Texas Instruments, Dallas, TX
Boat Lift Controller With Remote - 12-Sep-14 -Design News: At my lake home, I have a Shore Station boat lift to lift my boat out of the water when it is not in use. The lift has a manual crank and wheel, which can be quite tedious to operate. I added a Lift Mate Universal motor from Shoreline industries to crank the wheel for me. This type of lift and lift __ Gadget Freak-Case #262

Camera remote Control system using Basic Stamp - The remote control receiver is a custom design based on a pre-built 433MHz UHF radio receiver, a decoder chip and a BASIC Stamp. The Stamp is expensive, but easy to work with. The receiver requires 8.5mA, plus 1.5mA for each LED (individual or segment) that is lit for a maximum of up to 23mA. in practice it is between 13 and 16mA. Pressing a button onThe remote transmitter causesThe receiver to consume an extra 0.2mA. in the 'power saving' mode the PBASIC 'nap' instruction is used in combination with turning all the LEDs off to reduce power consumption to 4mA. The battery should last about 30 hours of on-time. __ Designed by andrew @ scss.com.au
