Same here, my first too, just 5 min ago. WOOOO!!!
Almost had a heartattack though.
I was too lazy to solder it (ahem, I was too unskilled), and tried taping pieces of aluminum foil to the board. After 20 tries or so, I got frustrated and decided to hold down the aluminum foil with my fingers. Lo and behold, raincoat started erasing the TSOP. I was so shocked, I let go, and it stopped at 90 percent ERASING.
Being the noob that I am, I didn't realize I could just program it again if I don't turn off the xbox until about 5 min later. Thank god there were no power outages.
