iPod + Nike Dissected

The guys at Spark Fun Electronics just can't leave well enough alone. They have to go taking things apart that should not be taken apart. Now they've got their hands on the iPod+Nike kit, and they have a rather extensive write-up over on their site. Perhaps the most interesting thing is their finding that the kit does not contain an accelerometer as just about everybody thought. Rather, the shoe sensor merely contains a switch (apparently piezoelectric) that sends a signal back to the receiver on each footstep. That's considerably less sophisticated than I would have expected from Apple, but if it works, so what. If you're the type that likes close-up pictures of circuit boards and can read schematics, check it out.

Thanks Roberto!
