Problem Statement (Finish description)
Science, Technology, Engineering and Math needs to be displayed. A scanner can be taken apart, mounted on plywood and then mounted on a wall. The scanner's parts could be functional, but exposed so everyone can see how it works. The scanner's parts could turn on when someone walks by. This being the initial idea for the scanner, quickly changed. We ended up deciding to start in a different direction. Our teacher Mr. Foerster showed us a video of a beat bearing. We didn't want to go the normal easy route so we decided to go become a DJ.

Conceive
Market/Customer Needs People walking past rooms CL-158, CL-159 and CL-160 need to know that they are walking by engineering rooms. They need to be engaged in displays that reflect engineering, brand HCC as an engineering school and are memorable enough to attract visitors.

Initial target goals Plywood mounted on wall vertically with guts of a scanner on display.

Changed target goals Create a beat box machine using the scanner and new components.

System performance metrics Building and grounds can maintain floors, walls and ceiling infrastructure. Fire and safety codes are not violated. The light beam in the scanner may need to be replace with EL wire or RGB LEDs because of possible damage to eyes.

Project cost and schedule Cost of plywood, plexiglass and mounting hardware could exceed $100 per 2ft by 4 ft section.

Estimation and allocation of resources Resources can all come from engineering department, donated scanners and existing disposable resources in the engineering room should cover most other needs.

Alternatives This conceive focuses on the "science on display" finished vision of this project. Other conceives could be written based upon:
 * Expose the wires that turn off the light bar and motor that moves the light bar in a scanner so that it can be used in this music project.
 * Develop a new circular track for the light bar so that it moves in a circle around an object carrying a digital camera that records the light bar illuminating the object to build a 3D scanner.

Design

 * Reverse Engineering:
 * The faceplate was removed revealing the scanner assembly as well as the userface and the motor used to move the scanner along the device
 * The scanner was taken apart revealing the electronic reader, however this was not essential in obtaining the goal of the project.

Next steps

 * Finish learning to program the motor with arduino
 * Control motor with ardduino
 * Control light with arduino
 * design/build the base with the music board
 * Attach scanner reader to the music base
 * Program the music base with arduino
