I wanted to share a project that I just finished with parts mostly from Adafruit. I have also posted schematics, code and pics which might be of help to others. I just wanted to share. Thanks for all your help… A few months ago, some college colleagues and I started work on a prototype for patent number 7,535,358 B2, Method and Apparatus for Electronically Tracking Luggage. This was the Xerox fellowship project that our group had to complete for the semester. Having led the effort and tackling the hardware aspect, I decided to publish a small report on the work that was accomplished along with the design details. All the hardware that was used is open source and cost around $250.
