    The Sound of Distance | Final Project 

  • Siwen Li 8:42 pm on November 29, 2013 Permalink | Reply  

    Role Prototype [FINAL] 

    My idea for final project is a distance-senstive instrument.


    1. Facing a wall with marks for different music notes on it—from bottom to top, the user move one hand up and down to adjust distance from the ground where the distance sensor is placed.

    Different distance values corespond to music notes, which will be heard from the buzzer. Bascially, this distance-based instrument hopefully brings new experience to players with the joy of sound, music and movement.






    2. New to the instrument, the step a user will experience is that he/she will be taught to play a simple built-in song by the machine. LEDS embedded alongside with the marks will guide users through the whole song—the user simply move his/her hand accordingly to the lights.

    After that, a user will be able to play any music he/she wants.






    3. Due to the limits of a human being’s height and consdering the accuracy a distance sensor can get, there will be one 7 music notes marks on the wall.

    In order to reach other ranges, the user will use a cup filled with salted water to connect different sets of notes—when the cup is tilted, one wire will be connected and therefore conducts the electricity to trigger certain range. This is also a new user experience which I think could be potentially fun.

    What did you find difficult about building you project?
    Never touched coding before coming to DT, I definitely find the logics of this projects challenging—Simon says and then user react then Simon says again and go on.

    And that’s not all. Because just when I though I’d completed the coding and everything works perfectly, and tried to get the game enclosed, I got so frustrated by the new button pad I bought, which I did included in my proposal. I simply want to apply my idea of combing LEDs and button together, but the circuitry is too complex for me to comprehend. Nothing gets more depressing than a formerly perfectly working game failed after transplanting onto the new PCB.

    But thanks to Max and some online tutorials, finally everything back to functioning well.

    What did you find easy about your project?
    Laser cutting turned out easier than I thought, since it was my first using the machine. And I’d definitely love to keep cutting!

    What surprise found you while building your project?
    I think underestimating the difficulty of using the fancy button pad ended up surprised me really hard. I didn’t have enough time to figure the circuitry out and put everything together before the show day.

    Proposal for Simon Says Game 


    When I was shopping on Sparkfun, I came across this really cool-looking button pad, which combines LEDs and buttons together. I immediately think it perfectly fits in in my projects.

    As for the major enclose, it would be a acrylic box. Since Simon Says is an reall old game, my idea is to give it a brand new, modernized look.

    Maker Faire Observation 

    1. ModiBot by GoGoDynamo

    photo 1photo 2 copy

    It is a character design system created through 3D printing. There are lots of 3D projects on display at Maker Faire, what makes it stand out is, as far as I think, these action figures snap together with a ball-and-sockect style attachments, and they can also be split into smaller pieces, which makes them easier to manufacture and people can creates endless characters with different mix-and-matches.

    2. DIWIRE by PensaLabs

    This is a machine that can print lines out of metal. Any 2D shapes in a .SVG files drawn on a computer can be wired out by the machine based on the data sent from the computer. And several 2D shapes can be soldered or clipped together to create 3D structures. The two legs of the metal glasses in the pictures are bent to an 90 degree angel after the shape of the frame is wired.

    Connection can be easily accomplished by a USB cable.

    3. Bee Keyboard by MakeAnything.

    Being touched by the “bee”, a “flower” will produce sound in a certain frequency, which makes a note. Then by connecting the bee to different flowers continously, people can play a basic scale.

    The idea behind this project is nothing new or hi-tech. I simply adore the idea, and this is one of the few projects I think I can make at the moment.

    Bio_Siwen Li 

    I’m from China. Studied journalism before I came to Parsons. The reason why I’m here in this class is because I want to learn something new as always.

    My favorite toys in childhood are probably building sets, Lego sort of things.
