Detecting IR frequencies

I want to give my bedroom the special treatment for CHRISTmas and decorate it up. I have one of those Wild Planet (the company that makes all that spy gear for kids) motion detectors. I am wondering if there is some way to find out what frequency(without buying an ir detector from Radio Shack, the remote for my Altec Lansing iM3 Ipod speakers told the Ipod to play, so that whenever somebody walked into the room Manheim Steamroller, and other Christmas music, would start playing.

Then maybe I should just go super primitive and have the thing trigger a diack feeding a transistor to run a motor and manually push the play button.

My dads multimeter has a Hz% button on it. Not exactly a multimeter but god enough.

You can use an old Ge glass diode and scrape off the lacquer, then hook it to a scope and blast it with the remote. Don't remember exactly but when I was young I'd done that a few times.

But don't get your hopes up. You Altec remote will most likely send some code. Knowing the IR burst rate alone won't help, you'd have to immitate the code as well.

Sorry dude, All of us here are Far too old to remember what childhood was like.

Sounds like a good idea, whatever it is. do a website! also search PIR detectors, quite easy to use. Think 8052.com has software for IR stuff/control etc, but it will probably be a bit intimidating if you dont know C or assembler grabage.

What are you getting for Xmas? an oscilliscope I hope... best workshop gizmo you can have

Modify your remote, install a mini plug jack connected to the play button. Then get the output of your motion detector to cause a short at the mini plug that mates to the jack you installed in the remote. You might need a relay to short the play button although it can probably be done with a transistor. Hey, I just had a thought, maybe these IR detectors already have a relay on the output. Mike K
