==Sudo Door Intercom==
There is an old intercom system that is wired from the [[ #Outside Facing Door| outside facing door]] up to the [[phone closet]] . One the first things we did when we got in to the space was to reconnect this intercom and attach it to a phone we had lying around. Here's a picture:
Right now if the space is occupied you can get in without a key by:
# Pressing the intercom button outside the door
# Waiting for a sudoer to answer
# Saying "I'm here for sudoroom", or "My voice is my passport"
# Waiting for an awesome sudoer to come and let you in
# Saying thank you!
==Door Open Indicator==
This project will detect if the [[#Inside Door|Inside Door]] is open and share that information.
Our current plan involves using a TI MSP4302553 via the TI Launch Pad to generate a tone. When the door is closed, the tone will stop. Anything that can pickup the audio will be able to detect if the door is open. We have a python script that does just that. Here is a picture of the tone generator in progress:
==Outside Facing Door==
The interior door, the westernmost one, will be controlled by a arduino interface that activates a motor that turns a key in the dead bolt. The arduino is activated by a python script doorman.py that runs on the computer sudoroom_blue (which also drives the 3d printer). doorman.py is a tornado based webserver . The server sudroom_blue has the static ip address 192.168.0.53, and the router forwards traffic to it on port 7836.
