RR1 INTRODUCTION
Welcome to the RR1 kit (and if you don’t have the time, the wired and tested
version). Let’s take a moment to help you understand the basic workings of IR
remote controls and how the RR1 works. This will better help you understand
what you are about to build. As simple as it may look, the RR1 is one of the
best remote repeaters money can buy thanks to some specialized technology
we have added to restore normally unusable signals. We will get more into that
in the circuit description section.
The RR1 has multiple uses. A common application is to extend the normal
range of your remote control by receiving your remote’s signal and then re-
broadcasting it a distance away via a wired IR element. Many stereo
component manufacturers skimp on the IR receiver sections of their equipment
so the range of the remote is very poor. Have you ever thrown your remote at
the power switch because the darn thing wouldn't work from across the room?!.
This kit helps to surmount that very problem. Another common use is to control
your unsightly stereo components that are hidden within a cabinet while you’re
entertaining. The unit allows your remote to control these items while they are
tucked away inside of a cabinet (or even locked away for security reasons) with
only the RR1 exposed so it can relay the information!
To use my house as an example, the stereo components are positioned
behind the couch and it is very cumbersome to have to reach way up with the
remote and beam it backwards in order to control them. Half the time it doesn’t
work even work for me because the batteries keep popping out of the remote (I
lost the remote’s back plate a long time ago in one of the many apartments I’ve
rented in the past, but that’s another story)! I don’t want to have to re-arrange
the room (that is the Wife won’t let me!) just so the remote will work better.
Instead I use the RR1 in front of the couch someplace and have it relay the
signal back to the equipment for me.
To increase the effectiveness of this kit, we take advantage of a high-
sensitivity IR receiver element which claims on its specification sheet to work
up to 36 feet (11 meters) away from the remote control (that’s about 30 feet
further than my VCR remote works!). Now I can truly atrophy on the couch
when my favorite program comes on and feel the pounds start packing on!
