  1. Audio Integration Harley Davidson Touring Design Review: 11/18/2011 Sponsor: Mike Meehan Team Members: Jacob Preston Ben Jochen Josiah Savino Advisor: Greg Donohoe 1

  2. Problem Definition Context: Who: Harley Bike Riders What: Limiting stock radio 2

  3. Problem Definition Goal: Design a product that takes in multiple audio sources, prioritizes them, and outputs the highest priority. 3

  4. Project History Biketronics Prototype PCB • Differences: • Used PIC16 • Three inputs • No User Interface • No Display LEDs 4

  5. Needs/Specs • Prioritized signals • Tonal Shaping • 2 Outputs • Powered by bike • Signal Amplifiers 5

  6. General Needs/Specs • Affordable <$250 • Easy to use • Durable • Weatherproof • Resistant to Vibration 6

  7. Prioritized Signals • Multiple Inputs Radar GPS IPOD RADIO 4 Inputs 1 Inputs 7

  8. Tonal Shaping • 3 Band EQ 1 2 3 8

  9. Product Research • Research current Products • Power Source • Radio Connection • Hardware • Compatibility • Cost Analysis 9

  10. Competition (1) • Mix It • 2 levels of priority • 3 Inputs • 1 Audio output • Price $159 10

  11. Competition (2) • Autocom • Communication Oriented • Not meant to mount • Aux out only • Price $415 11

  12. User Interface Options • In Fairing (No external interface) • Handlebar Connection • Wired/wireless remote 12

  13. In Fairing • Pros • Easy to implement • Inexpensive • Protected • Set and Go • Cons • Difficult to adjust Settings 13

  14. Handlebars • Pros • Easy to adjust settings • Many control options • Clean/compatible with the bike • Cons • Expensive • Difficult to connect • Overly complex 14

  15. Wireless • Pros • Clean • Easy to use • Cons • Costs • More complex implementation 15

  16. Wired • Pros • Simple to setup • Easy to use • Affordable • Cons • Bulky • Limited controls 16

  17. Powered by Bike • Cigarette Lighter port • Piggyback Spade Connector 17

  18. Radio Connection • Connecting Radio to Device • 8 Connecting Pins • Line Vs Speaker 18

  19. Project History (Continued) Biketronics Prototype Firmware • Audio Ducking • A/D Converter • I2C Addressing Data

  20. Possible Issues (1) • Fade issues • Change delay durations • User Interface • Feedback • Multiple Outputs • Switching device • Distortion • Decrease input volume 20

  21. Possible Issues (2) • Overheating • Fins on the back of the device • Matching ITunes EQ • Compare software EQ • Hardware Communication • I2C 21

  22. Costs • Audio Chip • $3.53 each (quantity of 2000) • Microcontroller • ~$4-6 Depending on Package and Quantity • Casing • $4000 for Mold and Design • 50 cents each • Labor • ~at $17/hour and ½ to 1 hours 22
