I dont think this is possible. As has been said before, the signal is modulated. It is not just a "light on/light off" thing. The beacon is likely sending out modulated binary data, and the receiver gets the pulses, demodulates them, and then the software compares the binary signature. This is how a TV remote works. An analog detector would just get the average brightness of a pulsating source. Of course, all of this is unconfirmed - I have not seen the code yet and all the IR stuff is missing from our kit
