Mike,

Your schematic looks OK to me. One thing to check is the pinout of the voltage regulator. The pins shown look correct for the 78L05, but the part is called 7805. They are different. I would use a 7805, since they are available at Radio Shack. Also, you show an 8-pin dual row header, but the std size is 10.

Concerning the sw-only solution using just an IR receiver. That software seems to be only looking for Sony IR codes. How will that work with a bunch of teams at once? If everybody selects Sony, things will get very interesting.

Good luck,

Bob Grieb
