MP Posted June 26, 2005 Report Share Posted June 26, 2005 I have never thought about it, but it seems to me that a strong IR light source aimed at the receiver would saturate it and null any signals (pulses) coming from a remote.MP Quote Link to comment Share on other sites More sharing options...
hamoodyjamal Posted June 26, 2005 Report Share Posted June 26, 2005 Hi, What you’re looking for is a "Remote Jammer" found at http://www.electronic-circuits-diagrams.com/funimages/funckt4.shtmlI’m building a project which requires an IR LED to be oscillated at 56KHz. I thought, let me point the IR LED at the TV and see if the remote works. Walla, the remote was jammed. But I had to hold the IR LED very close to the TV's IR receiver. I guess this was because most TV remotes today operate in the range of 38KHz - 40KHz. I don’t think you'll achieve great distance with this project because remotes send data with the IR Light which can be picked up easier than just IR light. Anyway, let us know how it goes.Bye! ;D Quote Link to comment Share on other sites More sharing options...
