Mic Input
A mic input is needed for Access Control. This page is instructions on removing one from a Motorola cell phone.

Required Tools

 * Motorola cellphone
 * Torex Screwdriver

Disassembly


The mic jack that is to be salvaged

Next Steps
-Solder input mic jack to wires

-Connect to Arduino

Door Mount
A mount that is transportable that will not damage the door is required for the Knock Knock motor.

Required Materials
- 2 ratcheting straps

- Plywood

- 4 skateboarding wheels.

- 4 pairs of nuts bots and washers.

Required Tools
- Drill Press

- Micrometer

Assembly


The door mount with ratcheting straps.

Next Steps
-Create a way for the motor to open the door

Motor Mount
The old method of mounting the Motor proved to be very cumbersome and a guessing game. When the motor was removed and replaced back on the mount, several adjustments had to be made to the large amounts of nuts to get the right fitting. The new method would have the gears that protrude out of the motor sit internally within the door mount the gears would be out of the way and the brackets of the motor would sit flush with the door mount.



New mount

Gear Arm & Belt Tensioner
The gear arm will be the piece of access control that opens the door.

Nut Tapping


This is the motor, gear arm and belt tensioner working together to move the arm. The belt tensioner bolt was not completely screwed down in this picture.

Broken Gear Repair and Salvaging Unneeded Components


Video of Fixed Gear.

Problem
During testing the Motor began to fail. It appears a critical part of the gear supplying force to the rest of the knock knock components is broken a video of it can be seen here.

Next Steps
Repair of the Ac Motor must be done before further testing can be continued.
 * Update-Motor has been repaired but the solution for the belt slipping has not been found a video of it can be found here.
