AUDIO-VISUAL EQUIPMENT IS TYPICALLY UNWIELDY, EXPENSIVE, AND
IMPRACTICAL FOR AN AVERAGE CONSUMER TO CONFIGURE AND SET-UP. THUS, THERE EXISTS A
NEED FOR A PORTABLE, ACCESSIBLE, ADAPTIVE, AND VISUALLY STIMULATING PRODUCT TO SATISFY
THIS MARKET. SUCH A SYSTEM SHOULD OPERATE MODULARLY AS TO INCLUDE TWO PRIMARY
COMPONENTS: A MASTER COMPUTATION MODULE AND AN INDISCRIMINATE NUMBER OF SLAVE
WEB
CLIENT
LIGHT MODULES. THE MASTER MODULE WILL LISTEN TO AUDIO SIGNALS IN REAL-TIME VIA A
MICROPHONE OR LINE-IN INTERFACE. THE SIGNALS WILL BE DECODED FROM THE SUPERIMPOSED
FREQUENCY COMPONENTS AND SEPARATED INTO VARYING FREQUENCY RANGES. THE FREQUENCY

RANGES ARE SET EITHER AUTONOMOUSLY OR MANUALLY THROUGH THE PC SOFTWARE USER
INTERFACE TO CORRESPOND TO A SPECIFIC COMMUNICATION CHANNEL AND ILLUMINATION COLOR.
THE SLAVE MODULES ARE INITIALIZED BY THE USER TO BE RECEPTIVE TO A CERTAIN CHANNEL,
RADIATING AND SCATTERING THE RGB LED LIGHT IN AN OMNIDIRECTIONAL PATTERN, POWERED
FROM AN INTERNAL RECHARGEABLE BATTERY SOURCE. UPON NEEDING RECHARGED, THE SLAVE
WILL COUPLE INDUCTIVELY WITH THE MASTER, MAKING EVEN THE POWER TRANSMISSION
WIRELESS. THERE ARE CHALLENGES IN THE OPTICAL INTERFACING, EMBEDDED SYSTEMS,
COMMUNICATION NETWORKS, AND POWER MANAGEMENT THAT, NOT ONLY MAKE THE WIRELESS
AUDIO-VISUALIZER
UNIQUE, BUT A TESTAMENT OF ALL DISCIPLINES OF THE ELECTRICAL AND
ELECTRONICS CURRICULUM.

THE SYSTEM NEEDS ENOUGH SLAVE MODULES TO
SLAVE MODULES AND ONE MASTER DEVICE TO DEMONSTRATE MODULAR
DEMONSTRATE THE ADDITION AND REMOVAL OF UNITS
AND CONFIGURABILITY OF THE SYSTEM.
AND HOW THE SYSTEM RECONFIGURES.
THE MASTER MODULE MUST BE ABLE TO COMMUNICATE WITH ANY
SLAVE MODULE WITHIN A RANGE OF THIRTY METERS UNOBSTRUCTED.
THE TIME DELAY BETWEEN THE AUDIBLE SIGNAL BEING PRODUCED AT
THE SYSTEM WILL TYPICALLY BE USED IN MODERATELY
SIZED VENUES AND WILL NEED TO COMMUNICATE IN THE
AVAILABLE SPACE.

THE SYSTEM.
THE BATTERY UNITS IN THE SLAVE MODULES MUST BE ABLE TO BE
RECHARGED TO 90% CAPACITY WITHIN AT LEAST A 4 HOUR PERIOD.
THE SLAVE MODULES MUST BE ABLE TO BE CONFIGURED INTO SIX
SEPARATE CHANNELS OF COMMUNICATION.
THE SLAVE MODULES MUST HAVE A BATTERY LIFE OF AT LEAST SIX
HOURS WHILE EMITTING LIGHT EVERY SECOND.
THE SIZE OF THE SLAVE MODULES MUST HAVE A SIZE AND WEIGHT
SIMILAR TO A SOFTBALL.
THE PRODUCTION COST OF THE ENTIRE SLAVE MODULE MUST BE UNDER
$50 PER UNIT.
THE 90% OPERATING LIFE EXPECTANCY OF THE LAMP AND BATTERY
MUST BE GREATER THAN 1000 OPERATIONAL HOURS.
THE SLAVE UNITS MUST OPERATE UNAIDED WITHOUT EXTERNAL POWER
SOURCE AND WITHOUT A TETHERED COMMUNICATION CABLE.
THE SLAVE UNIT MUST APPEAR ILLUMINATED IN AN INDOOR
ENVIRONMENT UNDER NORMAL LIGHTING CONDITIONS.
THE UNITS MUST CHARGE IN A TIMELY FASHION TO BE
USED REGULARLY.
THE SYSTEM MUST BE ABLE TO REASONABLY DIVIDE THE
LARGE FREQUENCY SPECTRUM.
THE SYSTEM SHOULD BE ABLE TO BE USED THROUGH AN
EVENT.
THE SLAVE UNITS MUST BE ABLE TO EASILY BE MOVED BY
HAND.
THE SLAVE UNITS ARE INTENDED TO BE INEXPENSIVE,
REPLACEABLE, AND EASY TO PRODUCE.
THE SLAVE UNITS MUST HAVE AT LEAST SIX UNIQUE COLOR
CONFIGURATIONS.
THE SYSTEM MUST BE ABLE TO PRODUCE AT LEAST SIX UNIQUE
DIVISIONS OF THE AUDIBLE FREQUENCY SPECTRUM BETWEEN 20 HZ TO

Design Team 02
THE SYSTEM MUST HAVE A GOOD SHELF LIFE.
THE SYSTEM IS INTENDED TO BE WIRELESS IN MOST
ASPECTS.
THE SYSTEM SHOULD BE ABLE TO BE SEEN IN AN INDOOR
ENVIRONMENT WITH EXTERNAL LIGHTING.
THE SYSTEM MUST HAVE AN ADEQUATE AMOUNT OF USER
Slave
LIGHT
CONFIGURABLE OPTIONS AND ALLOWING UNIQUE OPTIONS
FOR DISTINGUISHING CHANNELS.
THE SYSTEM SHOULD BE ABLE TO SEPARATE THE AUDIO
SIGNAL INTO REASONABLE LOW, MID, AND HIGH
FREQUENCY RANGES.
