Music screensaver iteration #4 made on London Music Hack Day 2013

The date has come, and passed! Me, Jonas and Johan are at the Music Hack Day in London like we planned last time. We continued working on PartySaver [Read about iterations #1#2, and #3] and focused on two major additions: a Deezer app and a connection to Philips HUE lamps.

The architecture of PartySaver separates the player app from the party functionalities. Meaning it was pretty simple to create a Deezer app since we already had a Spotify app. (actually, it required quite some refactoring since this is hackathon code :P)

Integrating Philips HUE proved to be quite easy, but also disappointing at the same time. The idea was to take the dominant color from the artist wallpapers and just set the lights to that color. First we noticed that the dominant color was actually most often a shade of gray. The second surprise was how lacking the lights are in the color spectrum. If you don’t send a color it can handle, it will grab the “nearest” thing which is not the nearest color as I’d imagine it (different hue basically) but instead it gets whitened.

The image above shows a CIE color chart, and the little green triangle inside it is what Philips HUE can handle. Not much in the blue/green/yellow space… Next hack I’ll try to find a better color matching algorithm than the built in one.

Oh, a small improvement we made is that to find a party you just go to partysaver.se and it’ll check for parties within your wifi (actually, your public IP).

Next time we’ll also try to create the “standard” party functionality: party queue manager for party guests.

Update 2013-12-12: There’s a video of our presentation on YouTube. Also, we’ve talked to Deezer yesterday and are aiming at releasing PartySaver on their platform hopefully before Christmas (i.e. next week!)
