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

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

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

Project History Biketronics Prototype PCB Differences: • Used PIC 16 • Three inputs • No User Interface • No Display LEDs 4

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

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

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

Tonal Shaping 3 Band EQ 1 2 3 8

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

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

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

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

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

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

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

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

Powered by Bike Cigarette Lighter port Piggyback Spade Connector 17

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

Project History (Continued) Biketronics Prototype Firmware • Audio Ducking • A/D Converter • I 2 C Addressing Data 19

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

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

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
