BOARDLOCK project

Project Overview

Tired of your run-of-the-mill skateboard? Looking to upgrade it to the next level? We present to you BOARDTRACK: a slick skateboard equipped with a battery-powered Raspberry Pi, GPS chip, and accelerometer attached to its underside. Why? We're glad you asked... these small gadgets provide BOARDTRACK with the the capacity for user-friendly tracking of its location, acceleration, and average speed. Once collected, this data is displayed onto a monitor. But wait, there's more -- each display is unique to every trip, enabling you to access how far you have traveled, your speed at any location, and the highest overall acceleration reached. In this project, our team aims to manufacture a unique transportation method of utmost quality, aesthetics, and convenience.

Objectives

Old Objectives:

1. Attach ESC to Raspberry pi
2. Be able to lock board's wheels
3. Use raspberry pi bluetooth capabilities to lock board wheel from cellphone

New Objectives:

1. Attach a 3D-printed box to the underside of our Skateboard's deck, containing a portable battery-powered Raspberry Pi, GPS Chip, Accelerometer, and a LED pushbutton
2. Set up Raspberry Pi
3. Learning how the Raspberry pi and Python works
4. Understand how GPS technology works
5. Get GPS and Accelerometer to send data to Raspberry pi
6. Program button so that we can begin and end pi program
7. Program a Python Script which writes an HTML file which displays a heat map of route traveled

Challenges

We anticipated our challenges to mainly be using unfamiliar technology to all group members, including programming in python, the raspberry pi, accelerometer and GPS. In addition to these being new to us, we knew that we also were going to have trouble testing the GPS, especially if we were inside. The GPS specifically caused the most trouble, and was hardest thing to deal with in our project.

New Skills

Programming in python:

1. We learned how to program a python script to read data from a GPS chip and an accelerometer and write it to a USB flash drive.

• This required

1. We also developed a python script which would read the recorded data the USB flashdrive, and create a heat map on a google maps webpage

• This required

Using raspberry pi

Final Report

Designs and Solutions

Programming:

How to project GPS data onto Google Maps API? Hyperlink created

How to project Accelerometer data onto graph? X, Y, Z coordinates

How to program button to start/stop collecting data? LED light

How to extract data? Stored on USB flash drive

Wiring Connections:

F-F Configuration / Pins

Battery → Pi → button → GPS chip → Accelerometer → USB → monitor

Virtually every aspect of this project was learned from scratch...

How to:

• Parse/interpret/project data from GPS chip and Accelerometer
• Based on data collection, program button to respond accordingly

Results

On Demo Day, our team successfully met our goals, though not to the extent we originally envisioned.
