Project Concept

• System
• Smart phone/ PDA with Docking Station
• RFID reader reads tags off the products and
  updates the status of the kitchen.
• Smart phone/ PDA generates a shopping list based
  on ideal stock and current kitchen status
• Assumptions
• All the products will be RFID tagged replacing
  currently used UPC Barcodes

Architecture Block Diagram

• RFID sensors detect the tags using RF and sending
  data to CPU via Ethernet interface
• CPU shall handle the database immediately
• CPU shall wait until the device requests data and
  starts synchronize via Bluetooth interface

4
Status Update

• We finally found a RFID reader and an antenna to
  work with (phew!)
• Able to communicate with the reader through a
  laptop. We can get the information we want.
• Developed a simple Phone GUI. Not synchronized to
  take files received through Bluetooth. But the
  file can be read as a document in the phone.

Parts
Nokia E62
Gumstix with BT connectivity (on its way)
Thanks to Burcu Akinci for letting us borrow the
kit

Next Steps

• Get the gumstix soon (fingers crossed)
• Work on implementing Bluetooth connectivity via
  C.
• Get writeable (smaller) RFID tags
• Look into possibly getting another RFID reader to
  keep track of things that are disposed in the
  kitchen.

Lessons Learned

• Be weary of projects that require expensive
  equipment. (Unless..)
• Dont believe everything on the box. (Range
  issues)
• Tech support are some of the biggest helps you
  can get.
• Some things just dont work together (quite
  literally)
