PSP wireless heartbeat sensor hack

It's amazing what homebrew coders for the PSP are able to come up with, especially when you consider that the "solutions" don't really solve anything. If you've ever hankered for a heartbeat recognition ability for your portable gaming machine, then here it is. One guy called Art simply soldered a coiled copper wire across the microphone input, which allows it to pick up the signal from a wireless heartbeat sensor. The result isn't visually impressive -- he hasn't coded a graphical readout yet -- but it should definitely inspire confidence in the homebrew community's ingenuity. PSP pull-ups anyone?
