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
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
My solution choice Multiple Mirrors Oriented Similar to Venetian Blinds
Mechanical Components -Mirrors -Bearings -Frame -Shafts
Software Components • Hardware: • HCS08 Microcontroller • -Elmo’s E910.86 Sun Angle Sensor • -Servo Motors (Detailed Under Electrical)
Elmo’s E910.86 Sun Angle Sensor -Very Small, Blocks Little Light -Outputs a PWM signal to HCS08 with Sun X and Y Angle Data -Outputs Temperature -Generally Used for Automotive Industry for Auto-Tinting Windows and Climate Control
Electrical Components -12V Power Supply - 5V Regulator to Power Servo Motors - Schematic Coming Soon
Servo Motor • HiTec 1/4 scale and 1/8 scale • HCS08 inputs a PWM, pulse width determines angle. • Acts as a smart device in this system
Management • -Only Group Member. • -Spoke with Sales Representatives to Request “Samples” or Donations. • -Working in Conjunction with Other Groups to Share Responsibilities.
Coming Soon • Study of money saved through this system. Light bulb power/lux vs. Mirrors power/lux • Schematic
