using infrared repeater on an infrared receiver?

Postby peptococcusniger » Fri May 03, 2013 9:59 pm

ok, first of all...i'm not sure of the exact difference between an "infrared repeater" or "infrared extender" but it's function is to do what's described here in this link:
http://www.audioholics.com/tweaks/conne ... stems-work
or in this link as well:
http://www.audioholics.com/tweaks/conne ... stems-work

What I want to do is control a DC motor interfaced with an infrared receiver by using an infrared transmitter in another room without any wires. It's the same as saying you want to control your television (changing volume/channel or turning it on/off) through your remote control by being in another room. Problem is I can't find any repeaters that would do this for a DC motor. I am planning on borrowing the techniques described in this link to recreate the exact replica in order to make my own infrared transmitter / receiver combination :

OR
http://galia.fc.uaslp.mx/~cantocar/micr ... RFACIN.HTM

so I have chosen a picaxe microcontroller over basic stamp microcontroller but I'm not sure which one is more easier to implement. But the goal is the same: to use an infrared transmitter (which could be an existing sony remote control) to control a DC motor that is interfaced with an infrared receiver placed in another room, without the use of any wires. Is this possible?

I'm afraid it is not possible. IR signals won't go through walls or around corners. If you cannot run wires then what you need is a radio link in between.

There are several small units working in the UHF bands that would do the job. Your IR receiver would modulate an RF transmitter. The signal would go through the wall to be picked up by a matching RF receiver in the next room that modulated an IR emitter, or activated the DC motor.
