Shadow Patterns

Mounting motors! – something I failed doing a few weeks ago. What was I thinking attaching the motor to the white plastic lid … It flew off.

MOUNTING MOTORS PROJECT

–> EARLY DEVELOPMENT

My first instinct was to go to the junk shelf to find what was destined to be mine. I found a functioning turntable, what a perfect object for a motor perfect! I tried taking it apart to see the mechanics inside. However, when I opened it up I was overwhelmed by all the components. After some time of trying to rewire it, I put it back in the junk shelf.

–> SHADOW PATTERNS

Since faith wasn’t going to decide for me, I went back to my interest, optical illusions. I saw a motor sculpture project online where multiple sheets of perforated metals were used to create / animate various patterns according to their rotations.

This reminded me of when I looked through my window, through the wire windows against the sun (in Thailand wire windows are used to filter insects). I wanted to recreate the sculpture based on the experience, as well as recreate that experience in the form of a sculpture.

Materials

  • x2 Stepper motors – very slow drive
  • x2 Patterned acrylic sheetsI tried sourcing available materials but perforated metals were both too expensive and difficult to work with. Also, it would give a negative pattern effects ( holes will be dark). So I went with acrylic.Image result for perforated metal sheet
  • x2 Cork base
  • x2 Standing sticks (acrylic)
  • x4 Screws
  • x2 Arduino and jump wires
  • x2 Power supply
  • x1 Super glue (for acrylic)

Prototyping

  • TEST PATTERN

Process

Spray glue is better

Always use callipers

Test them holes

OTHER NOTES ON FAB

Generally I feel a lot more confident in making things and trying different materials and tools. This class has been one of the most fun classes and closest to my interests for me. I am inspired by a lot of examples given in class and on the blog and I hope to reach that point in craftsmanship and precision in the future!

ALTOIDS MONSTER – THE SLOT MACHINE!

Ideally this week we should take our existing project and polish its finish i.e. make a project enclosure. However, I do not have a project to enclose! As a result, I embarked on an exploration of my long time curious topic ‘persistence of vision’. There are many ways to illustrate the concept of persistence of vision but I chose the spirographs as the content. Why? Because they’re fun! Everybody can participate! And they have an algorithmic pattern which animate seamlessly regardless of the strobe light (as long as the pattern matches the light frequency).

BUT! The project required a lot of precision and testing so I had to save it for another time!
I then took a look around me and found empty Altoid tins and those became my focus.
ALTOIDS MONSTER – THE SLOT MACHINE!
If you get rainbows, you get free Altoids!
The original design (VERTICAL)
I started drilling and attaching components only to find that my breadboard cannot fit as the switches took up too much space.

The later design (HORIZONTAL)

I used the drill press to make the holes for the switches and the nibbling tool to cut the side for the power cable. Having an enclosed box makes it very easy put everything together (it just fits!).
My key learnings.
  1. The big drill bits can bend the tins
  2. The bid drill bits leave a lot of scraps on the surface
  3. Stick the wiring to the lid! Otherwise the wire will come off
  4. The object itself contains a lot of equity i.e. personality – using something familiar to people can make the thing itself more friendly
  5. Keeping some original parts make the object more familiar – i kept the inside paper of the Altoids
