Laptop Guard

Ever been worried about your laptops or personal items being stolen? Even if you step away for just a moment? Introducing the Laptop Gaurd

Story

Introduction

The four of us - Chris, Steph, Bernardo, and John - designed the Laptop Guard for out Product Design class. If someone were to steal the laptop or other items placed on the load sensor, the Laptop Gaurd is designed to sound an alarm, flash a Red LED and notify the user via text message.

Now that the Fall 2015 Product Design class at Penn has ended, Chris, Bernado, and John have decided to continue to work on Laptop Guard. We have recently been awarded the Berkman Fund, a non-equity grant offered to students here at Penn for their startups and technology projects. We plan on using the $500 on the refinement of our prototype and on market research.

Description

This project uses the following components:

1) TI MSP430FR5929 Launchpad

2) Wifi booster pack

3) Fuel tank batteyr boosterpack 3.7V

4) Button pad

5) Load sensor (FSR)

6) LEDs

The Laptop Gaurd is designed to protect your unattended personal items. First, the user places the items on the sensor and arms the device with a secret pass code. Any change in the weight above a set threshold will sound the alarm instantaneously. If the alarm goes off, the buzzer will sound, the lights will flash, and the user will get a text message notifying them their laptop has been stolen. To disarm the device, simply put in the super secret pass code.

int maxRuns = 100;   // Maximum number of times the Choreo should be executed

//Buzzer and FSR variables
