Receiving infrared (IR) signals while conserving system power is difficult, and typically requires the inclusion of complex power-management routines in the firmware. You can avoid that problem by ...

This infrared repeater system is used to extend the range of an infrared transmitter used at an audio or video equipment at 10 m. The original signal is captured by the infrared receiver (figure 1), ...

anyone got any sites that have em, I just got a RF Remote with a RF to IR converter box that works with all my Home Theater equipment, and I'd like to setup my PC to also use it, I have very cheap ...

This IR receiver based on ATtiny13 microcontroller is used to control a Media Center box via a remote. The circuit is powered by 20 pin ATX connector pin 9 “+5VSB” because it is the only pin that is ...

Here's a few details on the Infrared Remote Control Extender unit I designed and built to control my NAD T752 A/V receiver. The NAD T752 has an IR input socket on the back of it for system installs ...

Every now and then a remote control acts up. Maybe you are trying to change the channel on your television and it’s just not working. A quick way to determine if the remote control is still working is ...

In this article, we implement a rain and ice sensor by analyzing the reflection of an infrared (IR) light source. This project uses proven techniques based on multiple reflections of IR light in the ...

The new UB20M voltage detector IC in Fig. 1 enables zero-power sensing and listening. It allows circuit designers to eliminate standby power, to develop circuits that perform continuous monitoring ...

This project allows you to take the video recorder and satellite receiver remote controls upstairs, and operate the equipment from there. There is no additional cabling to install, the signal being ...
