paging service; its only use is for an interactive gaming environment. In addition, they are
more expensive than conventional restaurant paging services.
The bi-directional communication used by the RF transceiver in the Playmaker is a
feature that will be adopted. Also, the large (preferably graphical) display is a very important
feature that will be required in the design. Since this is a wireless device, long battery life, and
therefore low power consumption and high efficiency are major concerns and will be similar
to the game board. If time permits, menu and help functions would be features that would be
nice to implement as well in the design.
The Wireless ordering system to be designed is different from this in that it will have a
navigable menu environment that will allow users to place orders or select various other items
from the screen. It will also use a graphical LCD screen to display the data on the wireless
devices. Since the number of buttons will be considerably less, a smaller size and lighter
weight device will be designed as compared to the Playmaker.
Specifications for the Design Packaging
Materials List:
• LCD Display
• 5 push button switches [7-10]
• 16 LEDs
• 6” x 4” x 2” Project Box
• 3” x 2” x 1” Project Box
• DB-9 Connector [7-9]
Tooling Requirements:
The project packaging design uses common parts that are of standard form and are
readily available. The off the shelf project boxes will need to be cut to accommodate the display,
LEDs, buttons, and the battery pack. In addition, the PC board will be screwed into the project
