Similarity JukeBox @ ITP Winter Show

Showing my final at the ITP Winter Show was the most intense user testing process that taught me a lot about how to display my work and how to quickly explain what my project was about to the public.

If I had to do it all over again I would probably make the buttons on the interface have the play, next set, and last set symbols on them and move the fader down a little more. Although some people knew exactly how to use controls, there were a few that didn’t know where to start. Musically inclined people spent more time playing around with it and I was especially surprised to find that it was a big hit with high school students. I assumed that because a majority of the music referenced is from the 60’s and 70’s that they wouldn’t find it entertaining but I was wrong!

I realized after putting my wood panel into the laser cutting machine that I needed to make the squares for the buttons double the size. I also added the symbols for the buttons underneath which could explain why they were so close to the fader. This was my first try at the laser cutting machine, and my first solo fabrication project – not too shabby! I tried using the same font that was on my cigar box but it looks like I should have adjusted the spacing of the font because it’s a little bit different. I usedĀ Berthold Akzidenz Grotesk Bold and found it by uploading a picture of a word on the box to fontsgeek.com.

The final code:

I’m shocked that in three months I was able to go from making an LED blink and a circle move on the screen to creating a jukebox which has been an idea of mine for quite some time. I can’t say that I love coding, but using code to create this project definitely made me appreciate the power of that language.
