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!

Er, if it doesn't contain an accelerometer, then Apple is lying on their website. It seems unlikely they'd do that for such a high profile product. Are you *sure* it doesn't have one?

I have a friend who loved his device in the beginning. But the last 3 runs the device has measured time correctly, but not the distance. He travels a lot, not sure if that impacts the way it works? Any advice?

If it actually did contain an accelerometer, you could just stick it in your sock or something. Using a switch makes it necessary for the special hole in the Nike's sole, or the abovementioned hacks for your own shoe.
Does that mean it only counts your steps, regardles of the actual distance?

..."This means there is potential Apple programmed in some transmit features! It's possible that two of these units can be used to form a short-range link between iPods! I haven't a clue if Apple added this feature or not, but the hardware is there."...
Ok someone needs to get on this right away!
Since I posted my first message earlier, I went to town on my old Adidas running shoes. It went so well that I managed to do it with the new pair as well.
The first time I used an exacto knife and cutting pliers however the 2nd time I went with the Dremmel approach and it turned out really clean (who cares anyways as who's going to see it). Doesn't seem to bother me at all, the shoes feel the same.
I made one that is exactly like the marware version but i spent a whole $0.00 on mine. The instructions are here http://www.instructables.com/id/E1UQY2DB4XES9J4DU3/

I have some New Balance shoes that I use it with. I pulled the insole out and just went to town right in the arch with an exacto. Just cut a border about the size of the transmitter, then hack away with an exacto and pliers. I got about 1/8" indention inside the shoe before it started getting pretty hard to cut. I put the transmitter in, and the top surface of it, right around the red line, stuck above the surface of the sole. I thought this might be a problem, but I put the insole back in and tried it out, and I can't feel it at all - literally, feels exactly the same. My father-in-law did the same to his Adidas shoes and had the same results.
I've heard bad reviews about the external, clip-on pouches.
