The flowed light use the flowing of light to represent the passing of time. When you turn the light upside down, it will be activated and all light up in rainbow color, and when you turn it back, it would go off gradually from the top to the bottom of the spiral just like the hourglass. I hope it can be used as a Pomodoro light to help people to have a better sense of the time.
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: Step 1: Design the Structure of the Flowed Light
As you can see in the picture, the materials of the flowed light include
- A glass bottle (bought)
- The Hourglass (3D printing)
- Addressable LED strip (RGBW)
- A tilt switch
- HUZZAH & Circuits
Step 2: Step 2: Design the Circuit & Write the Code & Solder the Circuit
In this step, I design the circuit of the flowed light as the picture shown above. And then write the code and test it to make sure the function works well.
Step 3: Step 3: Modelling & 3D Printing
I measured the size of the glass bottle and then made the digital model according to the size by SolidWorks. Then I use 3D printing to print the object. And here is a hint for the 3D printing: Do NOT make any part of the product hollow and closed because it would be filled with liquid when put in the bath after printing.
For the hourglass I used in this project, the upper part is hollow and open so as to hide the circuit inside.
Step 4: Step 4: Apply the Circuit to the Form
This is the most difficult part of the project because I want to hide the circuit inside of the product and the space for it is super limited, so be careful of the size of the 3D printing model and it is better to keep some extra space for it just in case some unexpected things would happen. Also, in order to hide the circuit, I changed some part of the product. For example, change the UNO board into HUZZAH.
There are four little steps in this step:
- Reduce the space of the circuit as possible
- Put the circuit in the upper part of the 3D printing object and find the proper location to make sure the tilt switch works well
- Stick the LED strip onto the surface of the 3D printing (it is really hard, I used the double-sided tape inside and transparent tape outside)
- Find the proper battery for the board and test
And it is finished!
Thanks for watching! :)
