Most IR receivers cost $1 - $1.50. It's not worth your time to sort through obsolete junk.
In the schematic you refer to, power comes from the RTS & CTS lines, The zener diode drops it to 5V.

It looks really simple then. I think ill have a trip into Mansfield and buy one from Maplin. Should i be using a zenner diode? Ive heard that you should use a voltage regulator instead
