I've got an ATI remote wonder - this is a wireless remote (USB receiver). I'm still undecided on this as at present as the range is somewhat limited. When I tired it at work it had a useable range of about 10meters, but at home that range is seriously reduced to only 1 to 3 meters depending on the positioning of the receiver and orinentation of the xmitter. I found this was a problem with wireless alarm systems at home too - the specified range of 150meters was drastically reduced in my house to little more than 5 - 10 meters depending on the placement of xmitters/receivers. Tech support (for the alarm system) suggested high mineral/iron content in the brick work of the house or stray radio interference... could be the vast amount of cat5 and coax running throughout my house!
I've also only used this thing on windows, but I found details of a linux implementation for this remote that seemed to use the X10 protocol - not sure exactly what it would entail to set this thing up under linux though... You can now get these in the uk via www.mini-itx.com (your one stop shop for all things mini-itx) (They also ship worldwide - there is another supplier in the uk (where I got mine) but I can't remember off hand the URL) As for x10/physical connection - have they not heard of opto isolation? What is this one-wire stuff? Got a link handy? Will google it later... sounds interesting... ----- Original Message ----- From: "Roh ." <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, August 26, 2003 2:44 PM Subject: Re: [Freevo-users] RE: [Freevo-users][OT] radio frequency receivers > ...sorry if this is too off subject for some > > >or better yet abandon the RF thing completely and simply buy the right X10 > >modules and a cheaper Ceiling fan. home automation with linux is old hat. > >and has been done very well with a program package called misterhouse. > > > X10, um, what can i say, it opens up the old argument of using mains for > data. > as an experienced electronics engineer, i can say that personaly id never, > ever use anything that modulates my mains supply (240v 10/15A max here, > thats a potiential 2400/3600W load with a physical connection to my > computer/sensitive electronics - no thanks!!), be it X10 or those crazy > pest-repellant devices, or a number of other devices that do similar things. > > X10 is old now, it was old 5 years ago, although its popular still in homes, > almost all of the big electronics firms have been developing > newer/smarter/faster/safer methods for automation. and for the last 2 years > or so it looks likes Dallas's 1-wire technology has come out in front, and > has already been used in fridges and ovens etc, works on the JINI/TINI > technology, and has a HUGE potiential. > > >It's great, when the temperature in the room exceeds settings I have > >declared the celing fans there come on.
