Current Status

11/28/16 This BBB does not currently have an RFID reader attached to it. When plugging in the rfid reader from the front door and rebooting, it recognizes tags (only one, that worked in the past, was tested today) but doesn't unlock the door. This BBB has power and is running.

Next Steps

Add an enclosure and equipment label
Check the latch circuit so see if it is connected correctly, the power supply is working, and the transistor is working correctly
Move to a safer location possibly by the left side of the door closer to the latch.
Hardwire an outlet for power to the door latch and
Purchase a new RFID module, make it waterproof and put it outside.

Getting Your RFID Number From this Reader

To get the tag value, scan your new 125kHz (EM4001 card format), non-valid tag (you don't need to open the door, it will scan from the back) and visit backdoor.local:8080 (You must be connected to the PS1 network). Your code will be displayed there, copy from that page into the box on the members site and hit submit. It's important to load the page on the beaglebone before another member scans their tag.

Other Methods of Entry

HTTP

This device will respond to HTTP requests to open the door - these requests will need to come from the PS:One network. An HTTP request to:

http://backdoor.pumpingstationone.org:8080/open

will cause the striek plate to unlock for 5 seconds. Use this to unlock the door with your phone, for example.

Device Software

The software is running Debian (tracking testing) for the Beaglebone Black.
