So simply using it to gate the output of an oscillator (555?) should do the trick. The pulse widths I've worked with (if I remeber correctly) are fairly long so timing shouldn't be a major hangup. (Oh yeah, I think the output is active low.) It's a fun little item to have around - I used a 6811 to decode the output. I'd like to build a Universal IR _Receiver_ some day. --kyler
