Hi,

Let's say you have an A/V cabinet with 8 copies of the same device.
Could be a DVD, VCR, CD Player, whatever. All devices are the same
brand and model number, and are controlled by an IR-based remote
control.

For this description lets say these are all CD players.

You want to change the track on one of the players in the stack, with
the remote control. You do not want to change a thing on any of the
other seven. And you need this functionality to happen from 10 - 15
feet away, so walking up to the stack and putting the remote an inch
away from the IR receiver is out.

Is there some kind of device that would enable this functionality?
The only thing I can think of is to put IR targets in different
physical positions around the room, and relay the signals to each
device. But that is a pain when all your equipment is in a single
rack.

Does something to solve this problem exist, or could it be built using
STAMPs, etc?

Thanks in advance.


I certainly could build something like this, but it wuold not be
cheap... Think along the lines of a device that receives all the
remote inputs, and that device routes the codes to the desired unit.
Each unit's IR input port would only be able to see the device's
output port. So with the remote you'd have to press a button to start
the process, then a number for the unit, then the command for that
unit.

Peter,

Thanks for your response. Is the high cost in the build or in the design of
the circuitry?
