@Martin: The IR range depends on the type of IR LED. Katie has made some experiments. I don't recall the exact details, but I can send you one of mine.

So my question would be: what ranges do people get with their WP34S?
I obtain about 100 mm, which is o.k, but something like 500 mm would be nice. I do not need 10 meters and do not want to drain the batteries too fast.
I only was astonished about the power of the HP 48 - it seems to illuminate the whole room with his IR and can print even if not pointed at the printer.

I obtained my IR diode for the HP 20b from H. Pott together with his fabulous USB board, but am considering to make another WP34S from a HP 30b.
