Do you want the circuit to be all analog or digital?

There are two RPY97 IR detectors on e-bay at the moment, not necessarily direct replacements but I suspect that making them fit would be fun! 99p each at the moment!

Naturally, the OP didnt fill out his location, perhaps he cannot receive shipments from ebay.
