[ Telephone Relay ]

HARDWARE PROTOTYPE

Currently have 2 Plain Old Telephones - wired together with a 9v battery to act as intercoms.

Pending decisions on what this system will do.

Will need decorated as well - they look pretty plain so far.

Current options -

  • Simple Intercom 100-200 Feet apart
  • Intercom with active ringing when one is picked up
  • Interactive use with Raspberry Pi or other - usage undetermined.
