The Doorman is a 3d printable bot that handles access control. It uses Ti's MSP-EXP430G2 development board to listen on the UART serial pins for commands from a web server to unlock or lock the door, by rotating a gear via a stepper motor, controlled by something like an L293DNE dual H-bridge.

1. User accesses a secret web URL
2. Server uses PySerial to send a command to the MSP430
3. MSP430 detects command on the UART Rx pin and runs the stepper motor (via a dual H-bridge)

• Status updates of whether SudoRoom is open or not
• Unlock the inner door via some mechanism

• msp430/ code for the msp430 on an MSP-EXP430G2 development board. See msp430/doorman/doorman.c for details.
• web/ code for access control webserver running on Tornado (on a raspberry pi)
• models/ model files for the physical device

• Model files are not up to date, but more importantly, move away from blender for modeling. (maybe Autodesk Inventor Fusion)
• Add OpenSCAD/MCAD code for the gears
• Change gear ratio to make unlocking work better (stronger, as the key or lock-knob probably requires quite a bit of force to rotate)
• Add a mechanism for detecting end-of-rotation
• Upload electronics schematics and photos
• Move secrets into another file
• Move this project to a SudoRoom account
