Team 2: Non Recommended Project Fish Tank Maze
Mandatory Fish tank designed for fish experimentation Contains sensors for determining the position of fish Gates controlled by movements and decisions of fish Reward mechanism releases food to the fish upon completion of the maze
9
Team 2: Non Recommended Project A/V Switcher
Amplifier and output isolation Signal Sensing Inputs Outputs Allows the connection of multiple audio/video outputs to one input Can amplify audio signals Signal sensing and isolation prevents overload of the output device Auto-source selection
10
Team 2: Non Recommended Project Electronic Grill Temperature Control
Product is to be used for slow cooking meat Low power design will allow for battery operation Other options such as suggested number of coals based on ambient temperature and selected time may also be investigated
11
Proposed Product Summary
