Problem building a home-brew serial IR receiver

[<pa...@pa...>]

Hello all,

I'm trying to build a home-made IR receiver to use with my Ubuntu =20
Compaq Armada M300 laptop.  I'm using the same design from the LIRC =20
homepage, and http://lnx.manoweb.com/lirc/ . I've got the components, =20
and assmebled the receiever onto the D Sub connector.  I've also =20
installed the LIRC software and started to configure it.

When I do sudo depmod lirc_dev && depmod lirc_serial this works fine, =20
and /dev/lirc0 gets created as a charachter device.

I then tried using irrecord and xmode2 but get no response.

I've gone throught these steps:

Checked the receiever for voltage using my multimeter.  This showed =20
nothin at the sensor, which was due to the diode being the wrong way =20
around.

After reversing the diode I tried again, I now get 0.5V at the sensor =20
(not 5V!)  There's also only 0.5V between pin 5 and 7.  Without the =20
receiever theres 10V+.  Could the voltage regulator be the wrong way =20
around ? (it looks right, but I can't think of any way to test it's =20
orientation)

Any help would be greatly appreciated.

Thanks

Paul.
