    3D printed multi function night lamp

    Role

    Interaction Design, Physical Prototyping

    Details

    Solo Project

    Tools used

    Pen & Paper, Solidworks, 3D-printer, Arduino CC

    What is it

    It's multi-function night light which has various modes to change the color and brightness. The form of the lamp was ideated through sketching and iterative modeling. The functionality is implemented through an Arduino Circuit Playground. It also has a sound sensing mode which reflects the sound intensity into light. The design was 3D modeled using Solidworks and 3D printed.



    Design Goals

    Should look like an unconventional fireplace

    Size and function appropriate for a night light

    Should give a fun and playful vibe

    Will have power code as it’s intended to be used every night

    Moodboard & Initial Sketch

    I started looking for inspiration and created a moodboard. After that I start sketching out different forms to finalize my product form.



    Started 3D Modeling

    After that I started 3D modeling in Solidworks to bring my sketches to life.



    First 3D print

    Printed out my initial 3D model and but things failed.


    User testing and Feedback

    I conducted quick user testing sessions to get feedback on my design and the following issues emerged

    circuit board didn't fit

    friction fit failed

    power cord was brushing at top


    users didn’t understand what the buttons did

    edges were sharp and could cut the user

    Design Iterations


    I iterated on my design based on the feedback received from the user testing. The following changes were part of the iterative process.

    Integrating electronics & Coding


    I used Adafruit Circuit Playground as the main electronics tool in this project. It is an Arduino board packed with mant built-in sensors and output devices including two buttons, a switch, a microphone, a thermometer, a light sensor, capacitive touch sensors, an accelerometer, neopixels (LEDs), and one speaker. I used micro-usb power cord instead of battery as the lamp is supposed to be used every night.
    I programmed the board using Arduino CC by creating my own sketch. I used some sample code and modified as per my requirement.

    Final Print


    After making the revisions in Solidworks, I 3D printed the final version and integrated electronics.

    plug has enough space

    board sits as intended

    can finally hear the click on snap-fit

    relatively non-lethal edges

    Reflection

    Future improvements

    • Make a better support for mylar sheet or equivalent material
    • Mechanism to fix the board firmly to avoid issues while plugging in.
    • Make a non-ugly cap sensing control on top of the lamp.
    • Iterate on the material finish and patterns on the lamp.
