To Do list from July 16 2014 meeting

• Order some silicon potting compound to seal the card reader.
• Order some more cards and tags
• Order another card reader incase this on get mashed.
• Mount the card reader outside.
• Assenble and mount the controller inside.
• Wire the controller to the reader.
• Wire the power and Ethernet to the controller.
• Do some software magic stuff
  • also add read door open/closed status

Hardware Specs

• Basics:
  • Electric door strike (12V, 250 mA), will be wired fail secure, i.e. applying electric current to the strike will cause it to unlock
  • RFID/NFC card reader (MiFare cards)
  • Card reader can communicate via I2C/Uart/SPI
  • Two status LED's
  • Interposing circuit for door strike/RPI
• Outdoor enclosure to hold card reader:
  • (Tom McGuire fill in here)
  • Will hold card reader
  • Power LED - red LED that will be on continuously if there is power
  • Status LED - green LED that will blink one sequence with succesful card read and a different sequence if failed
• RaspberryPi:
  • GPIO list:
    • Status LED's
    • Door latch interposing circuit
    • Door latch buzzer (let the user know the solenoid has been energized)
    • Door reed switch (door status)

Software Specs

• Operating System: Raspbian
