RFID Doorlock
From Fixme.ch
Contents
Description
Build an RFID doorlock for the hackerspace. This doorlock should tweet when the space is open to alert standard members. Source code
Inspirations
- Open Access Control
- RFID Tweeter
- Various Hackerspaces Doorlocks
- iButton is opening doors at the TkkrLab
- Interactive Door as seen by chinese hackers
Proposed solution
For the electronic part, taking inspiration from the RFID Tweeter project seems a good start. It allows us to have the whole system embedded in a microcontroller (low power) and solves the biggest problems from such a device (in my opinion) ethernet access and tweeting!
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 ;-)
Dashboard
RFID Tweeting Test
- We already have an RFID Reader: Parallax RFID Reader Serial
- An mbed board and RJ45 connector will be ordered for the test
Mechanic Fixation
- We will use this lock to open the door: TSE BUSINESS SET 5001 PINCODE
Evolution perspectives
- Add network shield and use 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 perso 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
- NDEF Push in NFCManagerwith Custom NDEFMessage
