Recap: HackIllinois


Along with LA Hacks, we had the pleasure of attending the first (hopefully annual!) HackIllinois at the University of Illinois at Urbana-Champaign this last weekend. The event was entirely student run, spanned two buildings, and was attended by over 700 students. In-between waves of Nerf gun battles, delicious food, and a lot of Let It Go (or Let Me Code if you're brave) a ton of hacking was had.

  • Shoutout - Github
    Shoutout was a fun little app that acted like the Marauder's Map from Harry Potter. Pan around a map with your iPhone to see real time movement of your friends and little thought bubbles for what they're up to. If someone shouted that they were listening to something, you could hear that track via Rdio. Winner, best use of Rdio API

  • listen local - site, GitHub
    A beautiful looking page to explore local artists for a given location. Overlays a sampling of artists on a Google map of the location.

  • Lusication
    A custom player that finds listeners near by and showed you what they were listening to, while letting you vote on what you approved of.

  • inspire.me
    Provides a pick-me-up & motivation for your specific situation using quotes, images, and music.

  • radeocure An ongoing project that's a custom music exploration tool that has it's own recommendation algorithm- now backed with Rdio music!


There were a number of great hardware hacks as well, from modded microwaves to fancy light switches. This post's leading image is from team ILLights (Raj V. & Thomas D.) and a special shoutout goes to team Predacons (Mike B., Ismael R., Jake D. and Jimmy P.) who worked late into the night trying to hook an Rdio web player up to an Arduino input.

A list of all of the hacks is up at ChallengePost.

Recap: LA Hacks

LA Hacks Logo

This past weekend was a big one for college hackathons. We know of three that occurred, and we attended two. First up, we have a recap of LA Hacks, which was by far the largest hackathon we've ever been to. There were a ton of great hacks, and a bunch of them even use the Rdio API! (Imagine that!)

  • Spritz Beatz
    Spritz Beatz is a great API mashup if we've ever seen one. The hack lets you put in text to read through Spritz, then looks up keywords from the text in Gracenote to find background music for your reading, and plays that music through Rdio while you read. Winner, best use of Rdio API

  • Aud.io - Site
    One of the most common ideas we see at hackathons is the "Party Playlist App", which provides people some way or another to submit songs to be played next, a collaborative, real-time playlist, if you will. Aud.io is one of these hacks, with a nice design, and a Twilio phone number for finding tunes. Best of all, it texts you back, letting you know the app got your request. Winner, best use of Twilio API

  • Swatch'n Music - Site
    A twist on the classic Memory game, Swatch'n Music challenges you to find a target song in a grid populated with songs of simliar genre and mood. They used the Gracenote API to populate the board with songs from Rdio. Winner, best use of the Gracenote API

  • Ballad - Site
    Twilio may have given their API prize to Aud.io, but we thought Ballad took the "text a song to hear it" party playlist concept to another level. It's main distinguishing feature is that it counts votes, so if more than one person texts the same song, it'll rise to the top of the list instead of getting added twice.

  • Hear Me Out
    Hear Me Out is takes Tinder's idea of random match making, and puts a musical twist on it. Instead of being presented with a potential match's photo, you're presented with a song (provided by Rdio, natch). If you dig it, you can send a song back, and if you both like each other's songs, you can start a conversation and connect.

  • Hummly
    Hummly is a crowdsourced cover song generator, allowing anyone with enough audacity to sing portions of songs into their phone. The app then aggregates and mixes everyones singing into one full cover song. It also uses the Rdio API to provide the real version of the song for reference. Thankfully, the part of the app that aggregates everyone's singing wasn't built yet, so we didn't have to listen to the cacophony of 300 tone deaf people trying to cover Let It Go. We're hoping in version 2, they implement autotune.

  • Panda in Air - Site
    Panda in Air is a neat hack that lets you use Leap Motion to select music based on tempo. The hack uses the Gracenote API to find music of a certain tempo, and the Rdio API for playback.

  • ShitList - Site
    We were a bit confused by the name on this one. Their slogan for it is "With no other playlist will you give such a shit," even though we were expecting something entirely the opposite. The app is basically a text-to-listen playlist, but their logo has a pretty terrific artist's rendition of the esteemed pile of poop emoji. Pile of Poop

  • Moozik
    Unrelated to the bovine noises of a similar name, Moozik is actually a radio station generator that uses Gracenote for figuring out what to play, and Rdio to play it. They claim it's "the most beautiful streaming music web application of all time that suggest you music based on the artists you love." We'd be inclined to agree, but we're a little bit biased by this.

  • Mega Party Stack - Site
    An ambitious hack, Mega Stack Party intended to be the LAMP stack for your party. It provides an interface to Delivery.com for ordering food and booze, some tunes from Rdio, and (unimplemented, but intended) an interface to Uber to make sure everyone gets home safe.

  • CrowdBox
    CrowdBox was intended to be a voting system for jukeboxes in public spaces. At a higher level, the team wanted it to be the sort of thing people who run public spaces (like bars) could use to figure out what people want to hear over the speakers. Though the team didn't quite finish their original vision, they did get the app to play music from Rdio, and come up with a pretty elegant design.

That just about wraps up the Rdio hacks. LA Hacks was seriously the biggest hackathon we've ever seen, so while we encourage you to check out all of the hacks, we'd also recommend getting comfortable, because there are a lot of them.

Coming up next, our recap of HackIllinois!

Recap: BitCamp

BitCamp Hackers

Over 700 students gathered around the camp fire at the University of Maryland's BitCamp. Students from all over took buses to the event and slept at Cole Field House. In between hacking students enjoyed s'mores, a massive pile of Jenga blocks, and playing Xbox One.

Lots of hardware was available for the students to borrow and build with, but the most talked about projects were based on the Oculus Rift.

BitCamp Hardware Checkout

Here are the projects that used the Rdio API:

  • StepSync
    An Android application that plays music to match your running pace. Your pace is measured using the phone's accelerometer and the application plays tracks with a similar BPM. Winner, best use of the Rdio API.

  • Mooddio
    Figures out your mood based on your Tweets and plays music to match it. Second best use of the Rdio API.

  • SnapdioSite, Source
    Snapchat for Rdio. Send your friends 12-second clips of tracks. The track is a mystery until you open it.

  • MLB Walk-up SongsSite, Source
    Listen to the walk-up songs for your favorite MLB team.

  • BoogieBerry
    Social jukebox that pulls four random tracks from the Billboard Hot 100 playlist and lets the party vote on which track to play next. The jukebox is powered by a RasberryPi.

  • TwidioSource
    Add tracks to a playlist via text message.

  • guIDE
    All-in-one IDE where documentation and music are available with just a few clicks.

Recap: HackPrinceton

We had a great time at HackPrinceton this past weekend. Students from at least five different schools came together to hack on projects involving computer vision, revolutionizing education, and of course, audible delights. Four of the app submitted for judging used the Rdio API:

  • ShowerBuddy - Site
    ShowerBuddy makes it easier to do dangerous things with your smartphone: listen to music in the shower. Mashing up the Rdio beta JS API with the Web Speech API, the ShowerBuddy team came up with a well-designed way to control Rdio using your voice. All you have to do is figure out how to protect your smart phone from the water. Winner, best use of Rdio API

  • PinPlay
    PinPlay is a concept we've seen a few times before: geo-specific sharing of Rdio content. Their web app lets you find shared content within a two mile radius, and plays it back through our Web Playback API.

  • K-Jamz
    K-Jamz seemed like a neat karaoke app concept when we were talking to them during the hackathon. It was supposed to be a real-time karaoke app complete with live video feed. Unfortunately, we had a hard time finding them during the judging session, so we don't know how it turned out.

  • RdioMotion
    Control Rdio with the Leap Motion! Similar to K-Jamz, we had some difficulty finding the team when it was time for app judging. We assume their app worked as well as the Leap is able to detect gestures from the context of a browser.

All in all, it was a great time, and we were happy to be involved. We're looking forward to seeing all of you east coast hackers this coming weekend at BitCamp.

A complete list of the hacks is posted on ChallengePost.
