Homebrew monitors heart rate wirelessly
Add another thing to PSP's diverse capabilities. With the aptly titled Heart Rate Monitor, users can see their heart rate visualized on the PSP screen, provided they have access to a wireless heartbeat sensor. The author makes it sound so easy, though ! "Just a coil of copper wire connected across the PSP microphone input becomes the antenna for a wireless chest transmitter." The visualization is quite simplistic, but that's a given considering its "debug" status.
