Universal IR Remote Switch

Step 3 Parts Used

The SIS-1 chip is from SIMEREC.com. I got the bundle that had the chip with the IR receiver, but you can use your own IR module, if you've got one (or salvage one out of an old piece of equipment.) The reason I went with the bundle is that this particular IR receiver is wide band, which means that if I want to use a different button other than Aux-1 later on, I can without any problem. So, if you're going to use your own IR module, just make sure that it matches the frequency for the IR remote you plan on using.

The capacitor and resistor are for blocking power supply noise. You don't need them if you are using a clean power source, like a PC power supply, but I figured better safe than sorry.

I'm using a socket because I like to use it instead of a perf/proto-board for a small project like this one.

I decided to use a stereo jack and old headphone cable/plug for the IR receiver so that I could move it around. I really don't need it now because the AC switch will be behind a table that is able to pick up the IR signal when I bounce it off of the ceiling. But if I ever decide to re-arrange things the plug/jack/cable give me more options.

The switch is used to put the SIS-1 into program mode, so that I can teach it the Aux-1 button. I'm going to install the switch so that it's accessible after I epoxy the enclosure back together so that I can re-program the SIS-1 if/whenever I want in the future.

hmm... can you send me your product (i'm ready to pay :S) cuz i cant find those things ANYWHERE on web (so i cant build it at all)? ok nvmind i'm just kiddin' ^^
/me needs those chipz...

btw isn't sis-2 just rev. of sis-1?

I don't see a chip labelled SIS-1 on the Simerec order page. There's an SIS-2 there though. Maybe you could clarify - need to be carefull to get the right one methinks. BTW excellent job & great instructions. The chips are a bit on th expensive side though - would be nice (if you ever get time) to show how to use scavenged IR receiver parts so as to keep costs as low as poss. I have a room light switch that should initially have been two-switch -wired but was not, so IR control will save my legs & much irritation. Thanks.
