Help, can't find my IR receiver window!

I tried building my own blaster but could never get more than 3-4 feet out of it and it appeared to be very directional. Most of this I attributed to my through lack of electronics knowledge.

The Philips datasheet linked above shows the bottom of the transistor, which is confusing since you're normally looking at the top of the part. The angle of your pictures don't make it 100% clear but it looks like it is reversed. Once again: if you lie the transistor on its back on the table in front of you with the pins pointing downwards and the flat side (where the part number is written) facing you, the emitter is on the left, the base in the middle, and the collector on the right.
Here is a pictoral diagram of what it should look like:

One other thing I noticed is that when I set my universal power supply to 12VDC, it puts out around 16VDC (probably becaues it isn't a regulated power supply?), does this drop to 12VDC when in use, or is this going to be a problem? Thanks!
Rupp: The powermids do sound much easier, but there are 2 reasons why I don't want to go that route: 1) My RS 15-2117 remote has a similer repeater system (RF->IR), and I have some serious noise problems, and 2) I love doing things myself, just more rewarding (as long as I don't burn the house down that is). I have learnt a lot about electronics in the last few months just by playing with resistors and having you guys help me out with my projects, and it is getting addicting.

I agree with you Electron, learning to make your own little circuits is quite rewarding and addicting. Plus, you can make things in ways that are not commercially available, such as hide the IR LED in a picture frame, molding, etc and put the rest of the circuit elsewhere. I have at least as much fun designing and building things as I do using them afterwards.

I too find it's often more fun designing and building than using.

I also use Paint for quick sketches. Unlike Guy's, however, mine look like they were done in Paint.
You drew all those parts with just paint? Impressive!
You can also download the free schematic editor from www.expresspcb.com. It's pretty straightforward. It's designed to work with their PCB layout program and board manufacturing service but it works fine standalone.

I actually built one of these about a year ago but no matter what I did I couldn't get the device to work from about 4 feet and further.
