    Wildcat Thaumatrope 

    Idea
    Make a thaumatrope using Arduino and a DC motor.

    Prototypes
    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 

    Idea
    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.
