3D-Printed Night Light

Posted: Thursday, March 12
Finalized: Monday, March 30th
Due: Tuesday, April 14 (we will demo our work during classtime)

What To Do

Digital fabrication has become a hot topic area in computer science spanning computer graphics, optimization, and interactive computing. In this assignment, your goal is to design, model, and 3D-print your own night light (sometimes called 'nite light' or even 'nite lite'). While originally, I had intended for the night light to be 'smart' (e.g., contain embedded electronics to support interactivity), to simplify things I will loosen this requirement (see below). As noted in lecture, you can use the 3D printer in the HCIL Hackerspace (free, I will not charge for filament), Terrapin Works has also kindly offered to allow us to use their 3D printers for free as well as a special pilot program for this class (the Terrapin Works Rapid Prototyping Center is in Room 1102 of the Technology Advancement Building (TAP)), or you could use the McKeldin Library 3D printer at a cost of 20cents/gram (submit your request here).

3D Nite Light Inspirations

The following projects are not necessarily night lights but are all typically 3D-printed designs that incorporate LEDs in some way.

Using Autodesk 123D Design

You can use any 3D modeling software that you prefer for this assignment from the simple (e.g., Tinkercad) to the much more complex (e.g., Blender) but I recommend using either Tinkercad or Autodesk 123D Design. Below are some tutorials for Autodesk 123D Design:

3D Nite Light Specifications

  1. On paper, you must sketch 10 design ideas. To help you structure your ideation, three of these sketches should be playful, three should be pragmatic, and the remaining six are open to your whimsy/desire. Feel free to Google online to seek sources of inspiration (e.g., go to images.google.com and search for 'night light' to see many commercially available designs). You will scan in your sketches and include them in your wiki writeup.

  2. You must design, model, and 3D-print your own custom night light. You can use any 3D modeling software that you like but I recommend either Tinkercad or Autodesk 123D Design (the latter we used in class).

  3. The night light must fully enclose a working light (e.g., LED) or lights (e.g., multiple LEDs)

  4. The night light can be wall powered or by battery. You should not demo your nite light using [[#|your laptop]] cord. It must be wall powered or by battery.

  5. Bonus: add interactivity/computation (e.g., add a photosensitive resistor to turn the night light on/off automatically with ambient brightness of room, change the color of the LED based on orientation or sound level, remotely control your nightlight so you can turn it on/off from afar)

  6. Bonus 2: [[#|customize]] the fabrication of your nightlight using computational or generative design (e.g., see Skyline from Spring 2014).

Assignment Deliverables

The assignment deliverables are due before lecture begins.
  • Post your design to Thingiverse. This should be publicly viewable and accessible. You are welcome to use any share license you like on the object itself (including no license at all--e.g., None) to the extent allowable by Thingiverse.

  • Post a Wiki write-up to your own wiki subpage on this wiki (Template).

  • Presentation/demo. On Tuesday, April 14, we will present and critique our work to the class.

Completed Assignments

As before, please list your completed assignments below.

0. Project Name as a Heading 2 (linked to wiki write-up)

Your name (or a pseudonym)
A two or three sentence description of your artifact
