PROJECT BACKGROUND New cars use keyless entry Bring bikes up with that trend Remove the need for keys, cards. . . etc. Biometrics are getting cheaper Fingerprints are the most reliable

PROJECT DEFINITION Implement fingerprint scanner to be used for ignition of a motorcycle Train multiple users Reliability Ability to withstand road conditions Security

PROJECT COSTS Design Budget: ~$2000 Keep total system cost under $150 Part Atmel AVR pic Suprema SFM 3010 -FC Keypad Relay Cost Order size $2. 50 1 $125. 00 10 -99 $20 1 $15 (aprox. ) 1 Oscillator $1. 50 1 LED’s and Cap’s $2. 00 - Voltage regulator $0. 78 1, 000

VARIOUS SCANNERS Stand alone scanner vs. embedded scanner Various types Optical Thermal Capacitive Electric field

SFM 3010 -FC Thermal Scanner 3. 3 V power input Scanner operative range (-40 to 85⁰C) Module operating range (0 to 70⁰C) Store 1900 Unique Finger Prints

ATMEL AVR Currently working with ATmega 48 AVR series very similar: code easily ported Flexibility with memory, I/O, cost Operating voltage range (2. 7 V – 5. 5 V)

VOLTAGE REGULATION 12 V DC from battery 3. 3 V for scanner and AVR Possible options Zener Off diode voltage regulation the shelf regulator LM 2937 IMP-3. 3 CT-ND

COMMUNICATION Interfaces between AVR and scanner DSP Toggling GPIO pins (on DSP) Serial communication USART 0 Commands Send (AVR to DSP) Suprema DSP Enroll Identify Success, Failure Delete Receive (DSP to AVR) Succeed Fail ATMEL AVR Enroll, Identify, Delete

RADIO FREQUENCY IGNITION CONTROL Use RF Engage relay Start the bike Ease installation Replace starter relay Wirless: no problem because cable too short Possible back up system Downside: Cost Linx modules cost $8 to $10 per receiver and $5 to $7 per transmitter

BACK-UP SYSTEMS Key fob (RF) Keypad Handle bar combo Pros Wireless Already using RF for starter relay No hardware to carry Cheap, simple Universal: stock or custom Cons Need to have device with you extra piece of hardware to implement Smart card Bluetooth Cheap Small, light Ubiquity of Bluetooth phones Complicated to implement Near impossible to implement on a stock bike smart card required Need cell phone with Bluetooth capability A diff. transceive r Licensing expensive No external device needed

TRAINING Unique code with every unit inputs code using the keypad begin the enroll process User capable of programming own unique code User trained: system ready for use New user: repeat enrolling

PACKAGING AND POSITIONING Early stage Decision about choice of AVR chip Number of I/O ports Size of final program Choose ATMEGA 48 Placing Under seat Keypad over the rest of the electronics 11 -13 I/O Possibly removable Packaged Survive harsh environmental conditions Easy to mount Hidden scanner Small size

TOP-VIEW LAYOUT

ON GOING ISSUES Length of the ribbon cable Currently Suprema only has a two inch cable Would like to extend length to about 1 ft Suprema doesn’t have longer cable Longer cable not recommend Communication issues with extended length Heat tolerance of Suprema DSP chip Atmel AVR chips and scanner have industrial temp. ratings, Suprema DSP doesn’t
