ir reciever not working

[arun_aksharam]

I am now working on a ir reciever with tsop 1736. in txr part i put two multivibrators-first one for providing burst cycle and the second for 36 khz wave .but tsop is not sensing. can anybody sugest some txr ckts?

couple of things
first make sure your transmitter is working, you can look at the IR LED through a digital camera and should be able to see the LED as a purplish light to verify it's working.
this link has a circuit for a 38kHz emitter which you could tune to 36kHz

and the same site, but with a NAND IC

You can also use the TV/VCR remote to test the reciever. I used a module pulled from an old VCR once. No part number/specs. Wired it up like in Nigel's tutorials, used the remote and watched the osciloscope. Have no idea what the intended center frequency was, but think I used something around 37khz for an IR proximity detector. Get about 18 inch range...
