General Fixes

Configuring RFID System

The RFID system has a config.yaml file in logcards/ containing entries in a relatively obvious format. Once this file has been modified you should kill -HUP the process. You then need to copy the config to the Raspberry Pi doorbot. The simplest way to do this is as to:

Restarting

Rebooting the machine will bring up the rfid checkers automatically (it currently runs /home/pi/startup-rfid.sh from /root/.bashrc), to start chromium on the main screen do the following:

Opening the Door Remotely

Log

DoorBot 0

DoorBot 0 was the original doorbot running on JohnMcKerrell's old bitcoin mining machine. It used a USB MyFID reader to log visitors and hot desk usage and drove the screen next to the door. It was retired as a DoorBot on 16/11/2012
