[Interaction 1] Prototype: Pulsing LEDs

Initial Tryout

I have tried out several LEDs light effects to mimic our heartbeat pulses. Here are some of the experimentations:

Experimentation 1: The lighting above fades in and out based on brightness.





Experimentation 2: Light effect that mimics the heartbeat pulses. 
I try it together with different materials such as fabrics and crepe paper to see the effects of it.



Experimentation 3: Experimentation with the paper combining light effect 1.
I quite like this effect as it gives me a breathing, relaxing kind of feeling. [Approved]



[Rejected]

I also experiment with different hue values, but it turns out to be ugly. Thus, I decided to customize my own color palletes. And also, this is another light effect that uses millis to control the timing but it seems not aesthetically nice. 


This is a failed experimentation on random colors of the light effect.


Conclusion

Crepe Paper works well with the led lights, this is due to the fabric being too thin to refract the light. Thus, the fabric will only be used as decorations but not the actual interactive flowers.

Color will be randomized by using RGB value instead of mapping the hue value to achieve a better visual outcome.

[Interaction 1] Flower-Blooming Mechanism Development Challenges

Image
I have encountered multiple challenges when developing the structure for the flower-blooming mechanism. It took me one whole month++ to iterate the design and the whole structure for the flower-blooming mechanism to ensure it is doable for future production.  Design Development Output Arm For my initial design for the output arm, it is just a stick. My thought on the structure is by attaching the wires on the petals and wire around the output arm. However, it is not doable enough as it will be very troublesome for future mass production. Thus, I was advised to create a clamp for the output arm to increase the stability of the overall structure. At first, I don't get the idea. I just extruded a triangular shape from the output arm, and it looks horrible and serves no purpose.  I sought help and get some advice from experts on the clamp who specialize in engineering. I also further modified the model on the length and shapes to evaluate the best design for the mechanism. Fo...

Final Prototype: Night-Blooming Flowers Physical Light Installation

Image
Finalized Flower-Blooming Mechanism Design Plan 3D Printed Mechanism The finalized printed blooming mechanism seems stable with self-locking nut. I test-run the mechanism and it works fine at this stage. Blooming Motion without Petals  5 Output Arms 6 Output Arms Blooming Motion with Petals Pulsing LEDs  Pulsing Light Effect 1 Pulsing Light Effect 2 Both light effects have experimented in the early stage. However, further refinement and debugging will be done to match the art direction of the overall project. Core Experience Video The video below demonstrates the core experience of the physical light installation. Current technical production that have been solved are: Connection between Master & Slave Arduino Flower-blooming mechanism [Stepper Motor] LEDs Pulsing Effect Heartbeat Detection Next Plan: 1.  Exploration on fabrications        -Design & Evaluate choices of material and art style 2. 3D print all the compartments (5-8 sets) 3.
