RESIDENTIAL ACTIVE DAYLIGHTING SYSTEM 4/21/2010 Alec Bornemann

BACKGROUND - Light Bulbs are Being Used in Homes During Daylight Hours While Sunlight is “Wasted” On the Floor - An Economical, User Friendly Way to Use This Sunlight is Needed

MORE BACKGROUND - Some Patented Designs Use a Single Large Mirror to Reflect Light - These Waste Space and Available Sunlight

POSSIBLE SOLUTIONS Redirect Sunlight To Desired Location Using Solar-Tracking Mirrors - Only Get What Comes Through Windows “Pipe” Light Using Fiber-Optics - Expensive, Not User Friendly

SOLUTION CHOICE -Multiple Mirrors Oriented Similar to Venetian Blinds

Software Overview

Electrical Components -5V Power Supply - 3.3V Regulator to Power Micro Controllers - HCS08 Microcontroller - Servo Motors

Electrical Schematic

Servo Motors -HiTec 1/4 scale and 1/8 scale -HCS08 inputs a PWM, pulse width determines angle. -Acts as a smart device in this system

Sensor Orientation

Management -Only Group Member. -Spoke with Sales Representatives to Request “Samples” or Donations. -Working in Conjunction with Other Groups to Share Responsibilities.
