3D printed multi function night lamp

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.
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
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.
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
