Summary:

I want to build a CIR receiver and transmitter for the headers on my intel DH67BL motherboard. I have searched for a circuit diagram / parts list / protocol description but to no avail.

Detail:

I have an Antec Fusion Remote Black HTPC case with an intel Dh67BL mobo. The case has its own IR Receiver (made by soundgraph) which is limited to The Veris remote it came with and MCE remotes (Supposedly). This works fine but I can't seem to get my Onkyo remote (came with TX-NR609) to emulate an MCE remote and hence have to have both remotes to operate things.

What I want is to use only the onkyo remote to control my TV, receiver and HTPC. Yes I could just buy a Harmony, but they are priced ridiculously and I would far prefer to build a receiver and use event ghost to CONTROL ALL THE THINGS!
 
Great! That was fast! The only thing I am not sure about is the part number for the actual IR receiver (the one with Vs,Gnd and Out). any idea, biena?
 
Vishay TSOP4838 works well, but there are a whole range of them that will work as long as it is designed for 38kHz.

I think that is the one I was looking at actually:) any idea where I can source the LTR-301 in cape town. The only place I found is mouser and they are based in the UK I think and want $60 shipping...

You guys are great, have you built your own CIR receivers?
 
Trust me the TSOP4838 will be a lot easier to use than the LTR-301 as includes auto gain control amp, filtering and demodulator all on board. You will still have to provide this for the LTR-301.

Unless of course you want to get down and dirty.....

They are used on the DSTV decoders, and we use them here for a different application. I have lots lying around, so if you want to organise collection I could gather a few up...

my understanding of the CIR spec is that you can use the TSOP for compatable remotes, but need the ltr-301 to incorporate the learning function...
i appreciate that offer, they aren't exactly expensive, so i will see if communica can sort me out first.
ciao
