=Problem/Finish Description=


 * 1) Allow students to access the lab during school hours
 * 2) No modification to the door
 * 3) Door retains original functionality (can still open by hand and allow wheelchairs through etcetera..)
 * 4) Nothing visible from the outside - only required for the knock recognition design

Current team's finish statement


 * 1) Solve problems with second build
 * 2) Finish case for the first build
 * 3) consolidate and condense all documentation /create clean platform for next team to build from

=Conceive=

This project started almost 3 years ago, when the need for students to access their projects became apparent.

The administration of HCC have a very stringent set of requirements regarding the functionality of a "door" such that it serves all of it's functions to their fullest.

Security is then tasked with ensuring these objectives are met, which turns into a whole lot of silly rules about who can open a door

Students just want to get in and do work.

=Previous designs=

This project has been going for several years, and has never come fully to fruition.

=Current design=

This model took a very straight forward approach, the main innovation being the mounting system of the motor to the door.

=Implement=

Once the project was functional, the task was to teach everybody about it, and begin brainstorming improvements. Repeat the CDIO process

It was presented to the engineering seminar, and again on projects day.

=Operate=

The box

=Next Steps=

Continue design refinement:

-Make the design look better, create a nicer more compact package, potentially move Arduino/motor shield, pezio, and power supply into the box

-Design our own circuit that takes the arduino/motor shield out of the equation all together. Play with the FPGA's

-Improve security concerns. Future team could make an RFID reading system that just wires under the door, or build a camera that watches who comes in and out.
