(ACN refers to Access Control Node, a physical node attached to a tool)
I plan to
- Base the device on the Duemilanove arduino as it fits our needs and has a wide base of users.
- Use the wiznet chip for ethernet support
- Use i2c sm030 rfid readers
- allow different control outputs (relay, Darlington, servo control etc)
use flash memory for internal storage
Services
Mission critical
These must function without networking or main server available:
- Check if card in ACN local db and allow use if is
- Set tool into "out of order" mode
Non critical
- Add cards
- Report back to central server (usage etc)
Progress
I have made a prototype shield for testing code while the full design remains to be tested and produced. http://www.flickr.com/photos/solexious/6865500239/

Network protocol
Get card permissions
/[nodeID]/getpermissions/[hex pairs in ascii]/
i.e.
- /1/getpermissions/04FF7922E40080/
returns
- 0 - no permissions
- 1 - user
- 2 - maintainer
