 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)
+  * The Paxton cards may be non-standard and ID-12 doesn't read them. The next approach is to use the ACR122U with NFC stickers, as a parallel system. -- Tim, 2013-02-14
 A Raspberry Pi could be used to host the messaging bus, and to mediate between RFM12B and TCP/IP protocols. Aaron has one that can be used to prototype.

 Aaron built a housing for a new in/out switch, and the prototype build is in the lab but needs work.

+===== Status =====
+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.
+doorpi (Raspberry Pi in G1 Door switch) - see below.
+Publisher scripts:
+  * ip/mac sightings from the LAN (timpi)
+  * open/closed switch (wall-e)
+  * PIR sensor (wall-e)
+Subscriber scripts:
+  * sound sample player (timpi)
+  * speech player (timpi)
+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
