Handy dandy DIY IR widget –

The IR Widget captures the infrared signals used by remote controls. It operates in a way that makes it compatible with modern multitasking operating systems. It is able to determine the carrier frequency and demodulate the carrier in the digital or analog domain. The captured information can be used to view, recognize or reproduce the signal. The hardware is designed to be as simple and low cost as possible. A PIC12F629 was used for development, but almost any PIC that uses the 12 or 14 bit instruction set could be used. There are also 74HC based circuits for Luddites who refuse to use microcontrollers.

  1. Perfect!

    Just when I was starting to look for a way to ‘rip’ codes from auto audio remotes…here it is.

    I’ve been looking…anyone know where there are code tables for AUTO audio remotes? I can find sources for home units, but not auto yet….but I am prepared to haul the laptop store-to-store and get codes.

    Radio-be-gone project one step further….Thanks for the idea ElectroLund!!!
