You can still fit the larger voltage regulator (along with the larger
capacitor) inside the dsub hood.  Here's my parts list (all from

IR Receiver IC (276-640)$3.69
4.7 microfarad capacitor (272-1024 or 272-998)$0.99 or $0.99
1N4148 diode (276-1122 10-pack)$1.29
4.7 kOhm resistor (271-1330 5-pack)$0.99
78L05, 100mA, voltage regulator (276-1770)$1.49
9-pin D-sub female connector (276-1538)$1.49
9-pin D-sub metal (276-1508) or metalized (276-1513) hood $2.79 or $2.19

I made my IR transciever with an IR LED from an old remote control.
