    Pulsecube from Charl on Vimeo.

    Initial Idea:

    The initial idea is using users bio data to make a helpful self awareness tool.
    The I thought about Pulse-sensor. and was considering if the speed of clock can controlled by it.
    or, if I can use this data to alert users as well as its environment with some light transition.

    I firstly tried the 4digit7segment, wasn’t able to hack it.

    And The i use the leds instead.



    I finally enclosed my project with Lego, the Lego modulars are super adaptive for many open-source projects.

    My final project proposals 

    1. A hugging robot




    Using distance sensor as his eyes, the hugging robot is ready to give free hugs by lifting his arms.

    On the surface of his body, I’ll build a half-closed door and a servo sensor. Each time when his arms are up, the servo will quickly rotate which enables the door to open for a second.

    With Arduino in his brain and candy in his stomach, he will also give candy as well as hugs.


    2. An interactive pop-up book



    A pop-up book with sounds, and even video reaction. You’ll not only see the pop-up, but also feel the scene. I’ll select a story, make several pages, use different sensors to trigger the responses. You pat the dog and the dog will bark. You turn the page to a woods and a mockingbird will sing for you.



    3. An electronic twister



    A twister for saving the effort of the controller. It will be controlled by Arduino. By hiding LEDs and pressure sensors inside the rag/felt, multiple players will enjoy an electronic twister together.

    Role/Look and Feel Prototypes (Alec McClure) 





    Option 1:  Phototropic Drone

    Option 1 is an extension of an earlier project using photoresistors to give a being from the digital realm a foothold for sensing in the physical world.  The next step would be to give this being mobility.  The being thrives off photonic energy and will move towards light sources.


    (vehicle base)

    Option 2: Magnetic Tile Game

    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.

    Wildcat Thaumatrope 

    Make a thaumatrope using Arduino and a DC motor.

    a) I began by checking if the speed rotation was enough to make it possible:

    b) Then I tested a 3-faced version. But it didn’t work.cat_00

    c) I decided to test one that would animate the image, instead of just mixing it. It didn’t work out as I planned, though:

    d) So I stick to the idea of mixing two images. I draw this cat in an iPad, transfer it to paper and then to the final boards.

    Physical Display for Weather Data 

    A physical display for weather data.

    How it works
    The push buttons send a number from 0 to 3 to a Node.js application. The app connects to the Weather Underground API, requesting data from one of the four different cities — depending on the button pressed.
    The data is sent to an html page and also back to arduino. The temperature is then mapped to an angle, which is assigned to the servo motor.

    The scale has a very short range on purpose. The intention was to highlight the difference between the Brazilian cities and New York.

    Bear Bear – My Simon Says Game 

    I finally changed my idea into a diy game. Still using conductive thread, the bear will explore the world, the sky, the jungle and the the pool:)

    Simão Says 

    Final video!
    A Simon Says-like game, but with a knob instead of buttons. The user has to repeat the sequence of angles, pretty much like a locker.
    Thanks Laura SalaberryRenata Miwa and Alessandra Kalko!
    Soundtrack: instrumental version of “Amor de Chocolate“, by Naldo.
    Design process here.

    P.S.: “Simão” is the portuguese name for Simon. The name of the toy in Brazil is actually “Genius”.

    1.What did you find difficult about building your project?

    a. Find the threshold value which defines the status of ON and OFF for photo resistor. The perfect value should be like this: the photo resistor works once I touch it but when I jump between these photo resistors it won’t accidentally trigger any resistors in between.

    b. How to make it interesting for two players. I used to make the rules like this: one player creates and the other one follows. But I found this might be boring for the first player since s/he only needs to remember a sequence. So I improved the rules like this: each player has to both follow and create at one time. This makes both of them highly participate by focusing on what each other creates and remembering former sequence. It would be more challenging and fun.

    c. Distance between each photo resistor. I tried several times to adjust the distance between each sensor, because either closer or further would decrease the experience when people play it.

    d. Improve experience. Currently there are only four photo resistors, which means when one player stands at one side and the other stands at the other side, one of them will cover LED when s/he touches the sensor. So there has to be a way to make it more convenient for people to play.

    e. How to make an enclosure. I want it to look really cool but I’m still figuring it out:(

    2.What did you find easy about building your project?

    a. The coding part is not so hard compared to the debugging process.

    b. Building circuit is easy once you have the whole view in your mind.

    3. What surprises you found while building your project?

    a. I felt really surprised and happy that people like to play the two players mode, at least they didn’t think it’s boring.

    b. I’m surprised that laser cutting is really interesting. I kept asking myself why I didn’t go there earlier.

    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.
