As far as IR receivers are concerned they will respond to a wide range of light sources (not just IR - but mostly - depending on the receiver). They suffer from drift caused by ambient light and interference from most common forms of lighting. Thats why IR signals are modulated, to introduce a usable amount of immunity.
I've been giving some though to creating an IR system for a COAX distribution so that I can have a freevo system in my office hidden under the desk (with all the others) and pipe the video signal round the house via the COAX (modulated into UHF). This is all acheiveable with cheap electronics and a pic or two. One thing that strikes me as directly related to your poweron via IR problem is that I was planning to use multiple systems piped round the house on different channels so the IR signals would need to be on seperate channels or all on a common bus, this can be done with an inteligent IR receiver using PICs to weed out the correct signal and respond only to that CODE... If I actually get started on this project (at the moment its all ideas) then I'll put it on the web for all too see... ----- Original Message ----- From: "Matthieu Weber" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, July 08, 2003 8:31 AM Subject: Re: [Freevo-users] Power on via remote > On Mon 07.07.2003 at 09:19:36AM -0700, Rich C wrote: > > Good point, but are you sure the sun could really > > cause an RC event?
