The idea is to build a simple RFID system to control the main door lock and the laser cutter for EB members/staff.

• https://pimylifeup.com/raspberry-pi-rfid-rc522/ (using a Raspberry Pi rather than Arduino)

Server side exinting code for authentication (in php):

• Docs: https://gctechspace.org/2012/06/door-opener-code-and-documentation/

Server side proposal:

• Django 2.1 + Python3 server backend
• Bootstrap4 web UI
• SQLite (or MariaDB)
• Simple HTTP API: https://server/?resource=main_door&action=on&pin=12345
  • resource = laser_cutter, main_door, lab_door etc
  • action = on, off (open, close)
  • pin = rfid ID
• HTTP status codes:
  • A HTTP status of 405 will get sent if you have the wrong pin number.
  • A HTTP status of 406 will get sent if you have an invalid pin (ie: no pin provided)
  • A normal HTTP status of 200 will return if the pin is correct and the door has been triggered.
  • A HTTP status of 407 will get send if you have just been banned (ie: too many incorrect attempts)

Hardware:

• SENS-26 MFRC522 NFC/RFID Controller Breakout Board
• SUNFOUNDER PN532
• Arduino nano + Ethernet shield
• Raspberry Pi 3
• Ethernet hub/switch
• Linux server (Raspberry Pi or similar)
• Relays
• Electronic door lock (ask Greg about those from aliexpress…)
