3
Background

• Single rotating beacon light exists currently
• Not very affective in direct sunlight
• Turn signals and other flash patterns impossible
• During previous race a beacon light burnt out
  causing the team to borrow another one from UND
• ASC guidelines specify lead and chase vehicles
  must have roof-mounted flashing amber lights

4
Background

• ASC Guidelines
• Lead vehicle must travel within 500 meters of the
  solar car
• Chase vehicle must follow directly behind the
  solar car
• Must be visible in full sunlight

5
Background

• Solar Team Requests
• Left, right, and other flashing patterns
• Wireless remote to control the lights
• Power for lights come from car battery
• Portable

6
Objectives

• Totally wireless hand-held remote to control
  lights on top of the lead and chase vehicles
• Push buttons on remote for left, right, and other
  flashing patterns
• Lights on top of chase and lead vehicles secured
  by magnets
• Simple installation and removal of lights

7
Preliminary Design Ideas

• Housing attached to lights which contains a
  microprocessor and receiver component
• Microprocessor responsible for controlling the
  flashing patterns
• Will contain an ON/OFF switch for power
  conservation
• LED on housing signifies ON/OFF, as well as a
  transmission being received

8
Preliminary Design Ideas

• Wireless hand-held remote will consist of push
  buttons to activate flashing patterns, ON/OFF
  switch, LED display, microcontroller,
  transmission component, battery power supply
• Should transmit over a range of ½ mile
• Remote will be able to travel between either
  vehicle
