3. Project Overview • Our project is to design and build an electronic monopoly game console. The console will output the visual board to a monitor, output sound via built in speakers, and send player information to android phones/tablets. Players will connect to the console using android phones/tablets and will be able to see game information including how much money and what properties everyone owns.

4. Project-Specific Success Criteria • An ability to display game information and accept player information on android device to play game. • An ability to display the game board and animation on a monitor. • An ability to output audio for dice roll and background music. • An ability to properly simulate monopoly game (keep track of money, property, position). • An ability to save game to flash memory and load game from saved data.

6. Component Selection Rationale We had to carefully consider and select the following parts of our design • The microcontroller • The power supply • The SRAM • MPEG Decoder • Bluetooth Module • Flash Memory

7. uController Selection Criteria • We required a uC with a large enough flash memory (512Kb) in order to easily store game and image data. • The uCgraphics element will require fast computation in order to compute images positions as well as manipulate and draw to external SRAM. • The uC had to be able to communicate with the MPEG decoder and Bluetooth module through UART and I2C.

8. Memory Selection Criteria • We selected a uController 512kb Flash and 128Kb SRAM. • This was because we required a large amount of flash memory in order to be able to save image data, bluetooth logic and game data. • We also added 1MB external SRAM because we needed to store a double buffered image for VGA output which is about 1MB in size. • VGA images are 640*480pixels.

9. Bluetooth Module Selection Criteria • Initially, we decided to use a Bluetooth transceiver. • After doing more research, we realized that we would have to sink in a lot of man hours to build the antenna for the transceiver. • In order to reduce time needed to get the Bluetooth up and running on our device, we decided to go with an off the shelf Bluetooth module.

10. Power Supply Selection Criteria • Our uController, MPEG decoder and Bluetooth module operate at 3.3V • The only component of our circuit that doesn’t operate at 3.3V is our Digital Analog Converter which operates at 5V • We choose a Linear regulator that takes in 5.7V-42V and outputs both 3.3V and 5.V with 350 and 430mA respectively • This enabled us to run all components on our circuit.

11. MPEG Decoder Selection Criteria • Our MPEG Decoder had to be able to easily communicate with our uC through I2C and UART. • The decoder had to have fast decompression capability to enable flawless sound playback from the uC • The decoder had to easily interface with a Digital to Analog Converter in order to output sound files

12. Packaging Design • Stationary • Plastic for Bluetooth • Simple one-button design for easy plug and play use • LEDs for Power and Player status • Holes in front for better sound quality 2” 10”
