Re: motherboard irda header - any use?

[<And...@we...>]

Hi
I posted an e-amil to this list some time ago asking for some one here 
in charge to put the schematics for an IRDA module onto the lirc.org 
page but noone did. Here's the postin gagain, hope it helps:
Hi all,
I built an IRDA tranceiver for LIRC myself. Since almost every new 
mother board comes with an onboard IRDA connector this can become very 
handy. It was pretty easy and I just wanted to point out that the PDF 
file below could be put here:
http://www.lirc.org/html/install.html#hardware
It did not take longer than 5 minutes to solder everything together on a 
test board. The parts you need, do not cost more than 10€/$ and you can 
use it as a receiver and transmitter. You can order them all at 
http://www.conrad.de.
Here the PDF with the circuit layout(page 6):
http://www.mikrobitti.fi/nettijatkot/2002/12/rakentelu/tfdu4100.pdf
Figure 3 shows VCC1 and VCC2. Since you usually have only one power 
source you can simply connect them.

  André.
