RFID Doorlock

Description

• Build an RFID doorlock for the hackerspace. This doorlock could tweet when the space is open to alert members.
• Version 1 Source code

Version 2

What we need

• RFID to open the door (125 kHz and/or 13.56 MHz)
• Add/(remove) rfid tags on the fly (without reprogramming)
• Logs of events in a database with precise tracking of time.
• Reliability

Version 1

Tasks

• Test electronic + software (on breadboard) for tweeting accordint to a RFID Tag
• Design and build mechanic fixation on door
• Design and test electronic + software (on breadboard) for the mechanic fixation on door
• Create PCB for electronic
• Start using it ;-)

Information

• RFID Reader: Parallax RFID Reader Serial
• An mbed board with Ethernet
• We use this lock: TSE BUSINESS SET 5001 PINCODE

Evolution perspectives

• Remote database
• Add buttons or mechanism to choose open duration time (The space is open for approximatly x hours), like 3 buttons (1h, 3h, 5h)
• Picture of the person who opened the door
• Android application using NFC, acting like a passive rfid tag. Is it possible ?
  • "Card emulation" mode http://developer.android.com/reference/android/nfc/tech/NfcV.html
  • Apparently in Gingerbread but not ICS
