My friend has this really annoying neighbor who pretty much has the TV on all day at max volume and has been pissing everybody off for at least a year. Since he lives in a third world country the police won't even bother to intervene. I've offered my basic Arduino skills to see if I could put together something that could turn the volume down from a distance but need a little help.
First off, I bought a couple IR emitters at SparkFun (namely this, and this). Unfortunately with my own tests, this only worked at at maximum range of 2 or 3 meters and I need this to go up to 20-25m (the good thing is that I have direct vision of the stupid TV set).
Of course, finding the proper volume codes for that particular TV and creating the software to produce these is another battle that I'll save for a future post if I can't manage on my own.
Is there a circuit that I can use to amplify these LEDs? If not, will an IR LED array serve my purpose?
