Infrared "extension" question (not Linux related)

[azambuja]

Ok, I was gonna post this in the hardware forum but since it's not Linux related...

Is there any easy way I can set a infrared receiver to receive (duh...) from one point, run the "data" (whatever it's called) through a cable and transmit it through a transmitter (...), withouth any modification in the signal?

Should be fairly simple right? I tried looking for this on the Internet but all I found was diy pc-(pda/cell/etc) modules.

Thanks in advance

basically u want to make a IR repeater (like a radio or wifi range extender) Im not sure that you can hardware a setup like that cause of comm. protocals, though it wouldnt be very hard or expensive to use a microcontroller to do the middleman stuff.

Ive got some ideas on how to check if it can be hardwared or what not else so pm me for some specs w/ an email addy and ill send them along (If the IR reciever and transmitter are manufactured the make and model stuff would be useful as well)


*though a quite and simple/dirty solution would be to use use a IR reciever-opt amp-transmitter (though there is no filtering of interference then though, also thats using pcb mount components)

Would any of these work?

They're for home electronics remote controls, but they just amplify IR signals, or convert them to RF and send them to another node.

Hm, ok, but these are bit sofistiaced, unavailable where I live, and also a tad expensive with conversion rates.

Yeahhh that's what I want, I think. What's an opt amp? :) But that's pobably exactly what I want, something like:

EDIT: found this page : http://www.hardwaresecrets.com/article.php?id=86 , looked it over a little bit, maybe I want something like this

receiver --> amplifier --> capacitor --> cable --> (resistor?) --> transmitter
?

Many thanks for the quick responses :)

Yeah that is simmilar to what i was thinking about (though id revise that circuit a little bit to do what you want)

to answer ur question an opt-omp is an amplifier (has other uses but its what ive alwways used them for)

(also is this computer to computer/device IR or for IR remote controls say for ur tv/stereo)

<edit>a search for "infrared repeater circuit" on google has some good results as well</edit>

Definitively IR remote

Thanks again ;) I'm gonna start googlin for that

EDIT: yeap... Google led me to this link http://news-reader.org/article.php?group=sci.electronics.basics&post_nr=204295

That ultimately led me to this link

(there are other options thought:

But it's a bit too much for me, I'm gonna ask for someone to build it I think.

Thanks a lot StarKnight83 :)
