  • Questions

  • Appreciation


Cordless Phone Paging Device

  • Idea

  • Current Paging Devices on Cordless Phones:

    • Beeping Sound

  • Our Design:

    • Lighted Display of Phone Location


Cordless Phone Paging Device

Original Design

  • Zone Boundaries

    • Two antennas at each boundary

    • Virtual map of the home

    • Detects a change in signal transmission


Cordless Phone Paging Device


Cordless Phone Paging Device

Original Design - Problems

  • Transceiver Chip

  • Proximity of the boundary antennas

  • Noise effects on the design


Cordless Phone Paging Device

Modified Design

  • Defined Zones

    • Handset

    • Zones

    • Base


Cordless Phone Paging Device

Modified Design - Handset

  • Constantly Transmitting

    • Timer

    • Inverter

    • Transmitting Antenna


Cordless Phone Paging Device

Modified Design - Zone

  • Constantly Transmitting and Receiving

    • Receiving Antenna

    • Basic Stamp

    • Transmitting Antenna


Cordless Phone Paging Device

Modified Design - Base

  • Constantly Receiving

    • Receiving Antenna

    • Amplifier

    • HC 12

    • Display


Cordless Phone Paging Device

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


Cordless Phone Paging Device

Future Improvements

  • More Zones

  • Zone Power supply

  • Antenna Improvements

  • Display
