Step 4Stick it in the D-sub
Now, if you took my advice, you've been stopping between every solder point and fitting the circuit into the D-sub to make sure it works. If you didn't take my advice... well, good luck.
Assuming you've been test fitting the circuit every step, this should be really easy. Just drop the circuit in and make sure no connections short to each other. If you have overlapping contact surfaces, just cut a small piece of electrical tape and squeeze it in there to insulate them. You could also use liquid electrical tape and coat everything inside... but that stuff is really messy and a royal pain if you ever have to work on this again so I'd recommend against it.
The last thing?
The last thing you should have to do with the D-sub is dremel out a rectangular area where the IR receiver can stick out the top. You'll also have to dremel a notch for the rounded receiver area. This doesn't take too long, but try to be fairly precise. If you can keep the area tight enough then the serial connector and pressure on the IR receiver from the D-sub casing will keep everything safe and snug.
Test him (or her) out.
Once everything is insulated, plug the little guy in and test him out. You'll probably want to do this before completely closing up the D-sub just in case you screwed something up : )
If it doesn't work, compare your circuit closely to the circuit diagram and retrace/recheck all of your connections.
