Rhythm Jogger
Just four easy payments of $9.99!!!
Proposed Goal
Our original plan was to make a jogging device that can do the following:
Play music and change tempo of the music depending on the user’s jogging pace.
Display useful information on LCD display.Allow user to download songs from PC and select
songs to play on the device.Heart monitor extension.
Original Design
Major Issues Resolved
Using two 89C55 chips to solve timer interrupt issues.
Midi file parser and timing algorithm for sending midi bytes.
Unknowns Known Now
2g and 10g accelerometers don’t matter that much in our data extraction routines.
Getting data input from keypad and display data on LCD display.
Operating system is not needed.
Design ChangesTwo 89C55 chips. One sends midi bytes to
the Atmel Dream chip without getting interrupted. The other one interfaces with the accelerometer, keypad, and LCD display.
Instead of matching the foot steps with drum beats, it will only match the jogging speed to the music playing speed (tempo).
Current Circuit Diagram
What Now
Implement what will be displayed on the LCD display.
Decide what functions each button on keypad should do.
Implement song selection.
Demo
Similar to the Affiliates Demo.Circuit is too large to jog with.May use a longer wire and attach the
accelerometer on hip.Improvements with keypad and LCD
display.Song selection will be included also.
