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 ?
