"Lights, Camera, Hack!"

February 28-March 1



Brandon Whitney, Ethan Wessel, Israel Torres

With laptop thefts on the rise and cloud storage becoming the norm, DROPLOCK comes to the rescue! DROPLOCK combines a user’s pre-existing Dropbox account and some good ol' bash scripting to track down a user’s laptop when the time need be.

Once reported either through DROPLOCK’s webapp or Pebble, DROPLOCK takes a snapshot of the thief and pushes the picture to Dropbox along with the laptop’s location and WiFi information. This information is then viewable online.

DROPLOCK lets the thief have two options to redeem themselves. We included: a method for the thief to pay it forward by donating to a charity through JustGiving or paying back the cost of the laptop through Braintree. Failing to make a choice after 30 minutes shuts down the computer. Throughout the process, quick notifications about the laptop’s status go straight to the user’s mailbox via SendGrid.

No Strings Attached

Kevin Sutardji, Randy Chan, Thomas Tsang

It sucks to be visually impaired and trying to run. Sure you can attach a rope to someone and so they can help you run. The problem is... it's a rope. It's not free or liberating to run with a rope.

That's why we created "No Strings Attached" A mobile hardware hack that is designed to help someone run with speed, confidence and freedom.
