:I built mine a few months back from parts at RadioShack. One thing the above design is missing is a resistor, which is important if you want to have the LED on for a while without burning it out. I forget what value I ended up using, but check the amp rating for your LED and use V=IR to estimate what R should be. Exactness isn't that important, just something to restrict the amount of current going through your LED. The wiimote sensitivity screen is very helpful for testing whether your IR pointer is producing any light and whether it's bright enough.
