Project Report |
Project Name -- Bar Coding |
- Design Brief: To make a bar code of your initials, full name, and date of birth.
- Context: Bar coding is Bar coding is a method for automating computer scanning of alphabetic and numeric characters while minimizing potential scanning errors. It is a system of wide and narrow lines and spaces which are used to represent alphabetic and numeric characters. A laser is used to "read" the patterns of light and dark. It converts this data into digital information that is usable by a computer. One type of coding is Code 39. This system includes "quiet areas" at the beginning and ending of a code as well as start and stop characters. These help ensure that the reader functions properly and that the complete codes are read accurately.
- Possible Solutions: Use a bar code generator, use computer software, cut and paste, and shading/colouring.
- Design Constraints: The following are some constraints or limitations for this project:
- You must complete the assignment on your own.
- One space on the grid (see below) is a thin line or space. Two spaces on the grid make up a thick line or space (see above example).
- Your completed work must be handed in during the next class.
- Before commencing the project, you can look up the various barcode characters in the Barcode-Alphabet.
- Detail Design: Follow the steps below to develop your design:
- Ensure that the work area is clear of hazardous materials (i.e., oil, gas, rags, wood, plastic, etc.)
- Make a near-invisible grid to lay out your bar-code characters. Beginning with the start/stop character, bar code your initials. Follow each initial with a period. End with the start/stop character.
- Beginning with the start/stop character, bar code your full name and date of birth. Do not forget to include the "space" character where necessary. End with the start/stop character.
