TalDoor (GatekeeperV2)

Spencer Kulbacki ~ CSH 2017-18

TalDoor (or GatekeeperV2) is a small POE door lock system that runs off the PocketBeagle and uses PN532 NFC module to scan and authenticate user ID cards and open the door.

Hardware:

• PocketBeagle
• Pn532 NFC Module
• Esimated 500mA consumption of entire device during idle operation. Peak of 800mA during read/write door motor operations. EST less than 3 WATT max POE requirements.

Internal Main Board contains:

• PocketBeagle
• POE module
• Ethernet to SPI module
• Door lock motor driver
• 3.3 to 5v step up for motor drive

External Reader Board contains:

• PN532 NFC reader
• Red/Green LEDs & Beeper for notification

Part List for the PCB

+/- some pin headers we already have ~30$ in components for one board (+PCB Cost)

~62 components specified in BOM (not counting extra male pin headers)

Software:

• LibNFC 1.7.1

Notes

• Paul's Github notes

• BestCo door lock info,sorta

• Setting up ethernet forwarding over USB for BeagleBone dev on a PC

  • Plugin the BeagleBone to a USB port on your computer
  • Install the drivers
  • In control panel -> Adapter settings, set the IP address of the USB adapter to 192.168.7.1
  • On the adapter that has the internet connection, enable connection sharing with the USB adapter connection
  • ssh into the BeagleBone (ssh 192.168.7.2)
  • Run command "route add default gw 192.168.7.1"
  • Edit /etc/resolv.conf and add the Google name server by adding the line "nameserver 8.8.8.8"

• Door locks are 5v motors that need ~70mA to turn a worm gear and "unlock" the turnkey.

• BeagleBoard uses 130mA nom (300mA peak)

• 4 Red 0603 LEDs use 80mA

• ENC28J60-I/SO uses 120mA nom (180mA peak)

• PN532 91mA nom (140mA peak)

• Esimated 500mA consumption of entire device during idle operation. Peak of 800mA during read/write door motor operations. EST less than 3 WATT max POE requirements.
