"Defenders of the Golden Axe!"

October 8-9



Eiran Danan, Hila Yonatan, Shahar Barsheshet

SAVR is an Android app that tries to prevent car accidents by raising awareness of bad driving behaviour. Powered by Estimote beacons and NodeJS on Heroku the app tracks when a user is driving a car, and punishes them for texting while driving. The app automatically transfers a fine to a pot for every transgression, building on a pot that can be used to donate to a good cause or build up a savings account for a loved one.

Paceifier is an Android app that tracks the driving behavior of your children. Combining the speed, acceleration, and aggressive breaking, the app is able to automatically add and subtract money from a pot that can then be transferred to the child when good behavior is shown, or to a charity if not. Powered by Rails, Javascript and Android, Paceifier connects rewarding children for proper driving with paying for good causes.

Hack through the night, or grab a nap, beer break, and maybe even a massage or two. On Day 2, we have rehearsals, more food, and hack till you hear our gong, signaling the end of hacking! Teams present their apps, judging occurs and prizes are awarded.
