Sadly, I did not. I have the source code on an old laptop somewhere. I was disheartened when I considered productizing it and discovered just how deep of a patent tarpit I was dealing with.

It's on my list to revisit in the future. At this point, most of the patents are coming up on expiration, and it would make for a great open source project. Hardware has gotten much better over the subsequent years; there are nicer lower power solutions with integrated Bluetooth LE as well as other low power wireless technologies.
