Build an RFID doorlock for the hackerspace. This doorlock should tweet when the space is open to alert standard members.

• Open Access Control
• RFID Tweeter
• Various Hackerspaces Doorlocks
• iButton is opening doors at the TkkrLab

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!

• 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 ;-)

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

• 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

• Youtube Video
