With the fall hackathon season underway, we’ve had a chance to introduce a ton of talented college students to Firebase. We continue to be amazed by the hacks students are building in just a few hours (with barely any sleep!).

Last month we participated in MHacks, where students used Firebase to build things like “collaborative graffiti via text” and “real world Pokemon”. At CalHacks this past weekend, the best hardware hack used Firebase for a shirt that tracks your posture in realtime. See below for a recap of our favorite Firebase hacks from MHacks and CalHacks.

MHacks

Abe, Chris, Joey and Mike from Firebase traveled to Ann Arbor, Michigan to support 1,100+ hackers from across the country at MHacks. At the end of the hackathon, 34 teams used Firebase to store and sync their app’s data in realtime. These were the Firebase top two:

VoteApp

Our top prize went to VoteApp, a web based voting platform where users can create a new poll and display the results in realtime. Designed to replace an expensive and specialized device currently used for voting in class, these four students wanted to build a universal and free solution. Use it to run your next classroom poll, it’ll be the easiest one you’ve ever done!

City Paint

Our second place prize went to City Paint, which aims to reduce the prevalence of graffiti in urban areas by creating an online graffiti wall. These virtual walls can be placed around cities, and residents can text ASCII art to the wall and watch as their tags are added in realtime.

CalHacks

Over half of the Firebase team had the opportunity to meet the 1,000+ hackers at the amazing Cal Memorial Stadium last weekend. We had a great time helping hackers, and were impressed by their uses of the Firebase API. Both winners of our prize connected hardware to Firebase for realtime IoT awesomeness.

Nextile Shurt

The Nextile Shurt team built a device with flex sensors and accelerometers that ran on two Intel Edison boards. It captured motion data in realtime and displayed the data on a web app. The best part? They attached their device to a shirt, so that when you move the degree of motion is stored in Firebase. It can be used to track posture or for physical therapy.

Pomsafe

Our second place prize went to the Pomsafe team. Pomsafe is a home security and automation platform running from a Texas Instruments LaunchPad, powered by Firebase. When the device is attached to a door, it monitors temperature in realtime and reports when the door is opened to detect possible break-ins.

We’re always excited to see what students build with Firebase in such a short amount of time, and we can’t wait for the next hackathon! Follow us @Firebase on Twitter to find out which hackathons we’ll be attending next.
