What is GNMS?

GNMS is a tabletop, multi-touch, computing surface to be designed by some kids. It is similar in functionality to the Microsoft Surface, but not at all a rip-off!

Design ConstraintsThe surface will need to:  • Compute application data

                      Processor• Handle extraneous controls and peripherals

                      Micro-processor • Display visualizations  

                      Projector• Capture human touches

                      Video camera

   

ProcessorIntel Atom D525

• Software application processor  • Human touch capture input from the video camera via USB• Visualization display output to the projector via VGA• Audio output via 2.5mm connector

Micro-controllerAtmel AT32UC3B164

• User input for projector brightness, On/Off, audio volume via GPIOs.

• Transmits user input to the motherboard via USB.• Controls a response LED and fan speeds via PWMs.• Input from external temperature sensor via ATD to determine

fan speed. 

Power Supply UnitRaidMax RK-380K

• 3.3V from a SATA power plug will power the micro-controller• 5V from the 4-pin Molex will power the IR LEDs• Normal 24-pin and 4-pin ATX connectors to power the

motherboard devices (CPU, CPU fan, RAM, etc.)
