 Aaron would like to discover more about the RFID cards used to access the building - can we use them to accurately identify users even without decrypting the content. Are they mifare? I have an ACR122U reader/writer en route and will research further.
+Proof of concept was successful.
   * Summerhall's access system appears to be from [[http://www.paxton.co.uk/|Paxton]] and not MIFARE compatible. ACR122U is unlikely to read the cards, but a cheap ID-2 or ID-20 might. -- Tim (following discussions with Aaron in IRC)

 ===== Status =====
-Tim's Raspberry Pi (timpi) is running an AMQP server in the lab.
+An AMQP server (RabbitMQ) is running on amqp.hacklab (one of the virtual machines).
+timpi (Raspberry Pi in G1) is running a script to play sounds and speech.

 Code has been uploaded to https://github.com/edinburghhacklab/hacksense and local copies cloned to /srv/hacksense (on whichever servers are used).

+===== Doorbot =====
+Aaron's new in/out switch is now operational. It houses two buttons, a two-line LCD, a 13MHz RFID reader and a Raspberry Pi ("doorpi").
+  * /srv/hacksense/services/doorpi/buttons - reads the buttons via GPIO and generates events:
+    * doorbot.buttons.{red,green}.{up,down,shortpress,longpress}
+  * /srv/hacksense/services/doorpi/lcd - listens for events and updates the LCD:
+    * doorbot.lcd.display - {"line1": "Hello", "line2": "World"}
+    * Optionally, add "delay" field to wait a number of seconds before continuing
+    * Optionally, add "flash" field to display the message for a number of seconds before restoring the previous display.
+Todo:
+  * Move the PIR sensor to Doorbot and add it to the //buttons// script.
+  * Move the speaker to Doorbot and copy the existing scripts from //timpi//.
+  * Implement the RFID card reader
