Cordless Phone Paging Device
  • Idea
  • Current Paging Devices on Cordless Phones:
    • Beeping Sound
  • Our Design:
    • Lighted Display of Phone Location

Original Design

  • Zone Boundaries
    • Two antennas at each boundary
    • Virtual map of the home
    • Detects a change in signal transmission

Modified Design – Challenges

  • Handshaking between Basic Stamp and HC12
    • BSII value: 11111101
    • Transmitted/Received value: (1)01000000
    • HC12 value: (idle 1)(start 0)00000001
  • Learning to use the HC12
  • Learning to use Basic Stamp
  • Hardware issues
