Why wait until 2015?
Inspired by 'Back to The Future II', this project is less 'Practical' than 'Proof of Concept', but hopefully it'll tide you over until Nike comes out with something more polished.
This was also the first time I worked with an Arduino microcontroller, and I wanted to get some experience with the little guy.
Operation is quite simple- step into the shoe and a force sensor reads the pressure of your foot and activates two servo motors, which apply tension to the laces, tightening the shoe. A touch switch reverses the servos.
Due to budget constraints, I only modified one shoe. Where did I put that darn sports almanac?!
And if you get a chance, vote for me in the Instructable USB contest!
Step 1: Parts & Tools
A shoe // a hightop with a lot of padding and undersole seemed easiest to work with and modify
Arduino // I used the Duemilanove
Motor shield // The kit from adafruit.com works great, and allows control of multiple types of motors
Force sensor // Also got this from adafruit.com
Servo Motors // again, also from adafruit.com. Gotta save on that shipping whenever you can!
Sheet metal // about 4" x 4", enough to keep it's shape but easily trimmed with shears
LED and a couple of resistors // I only had 1K's laying around, so that's what I used
9 Volt case, with built in battery clip and switch
Insulated copper wire // I used high and medium gauge
Plastic zip ties, various sizes // I went through a lot of these
Plastic 1/2" cable loops // used for organizing cables
1/8" braided nylon paracord // 10' should be enough
Just the basics- soldering iron, screwdrivers, etc. A hot glue gun is handy, too.
A USB A to B cable and a computer to load the Sketch to the Arduino.
