Kinetic Sculpture: Not Clock with Ben Light

Sat, 11 May 2013 14:50:00 -0400

Ben and I made a kinetic sculpture for the assignment “Not Clock” - something that measures anything but time.

Instead of time, we measured how far you could blow. We had a fan on one end, and measured the tiny bit of voltage it made, and used that as a signal to tell our motors how far to wind up our measurement triangle.

Motors:

Fan blow station:

Moving measure:

Some videos!

Designing the system that moved the measure was rather complex. We had to make sure it did not tangle the thread as it wound it up. We had to design a place for the measurement to hit on both ends - small switches that would then tell the Arduino “You’ve wound me up!” or “You’ve returned me to the starting place!”

In the two weeks to do the assignment, we didn’t quite perfect the mouthpiece - that is, the experience of getting up to the fan and blowing as hard as you could - but… people knew what to do, and wanted to compete and try their best to get the measurement farther than the person before them.

We were pleased with the overal aesthetic - clear, metal, a spot of color for the measurement bead - and the software behind making the winding work properly. I coded in a spot of apprehension, of suspense - how far will it go? Before it winds the measurement triangle up - and the same on the way down.

polar ice

concept 1: lamps with bases that are modeled on how big the ice sheet was at that time - 1980 vs. now. solar panels integrated onto the surface of the 3d printed objects - these panels power the lamp.

another take on the sea ice extent data - a coffee table where the surface is formed by layers of the sea ice year by year.

a sea ice extent coat rack, mirroring the pattern of ice melt and rebuild, where the hooks are monthly markers.

rhino tutorials...

“This year’s minimum extent of 3.4 million kilometers of ice is less than half of what we saw in 1980. Strikingly, two thirds of the loss of ice has happened in the 12 years since 2000.”

Idea 1:

Ice sheet forms from 1980 and 2013 as the base for two lamps:

Twin lamps, each of whose bases are sculpted by the different ice sheet edge data. One lamp has the edge first documented in 1980, and the other has a composite layering up of edges until the present day.

a. Or - twin lamps - one simply of 1980, the other simply of present day (no layering = simpler information)?

- The bases would have small (tiny) solar panels embedded according to the average number of melting spots on the glaciers. These melting spots are first caused by general warming / ice patterns, and then become a compounded / compounding problem: warmer or melting ice (or just plain meltwater) absorbs more sunlight than does healthy, cold ice.

- I propose harvesting that sunlight and feeding it into the lamp’s LED lights.

- For the 1980 ice sheet, the base would have more surface area and therefore more solar panels and more light.

- For the current ice sheet, the base would have less surface area, fewer solar panels and less light.

This proposal might have a few conceptual pitfalls: questions arise such as:

a. Well, why are you enabling more light at all? Isn’t the current ice sheet smaller because people use electricity and energy in such wasteful ways?

Because the light is solar powered, it seems to be a steadily strong concept to me. To be discussed.

b. How will you decide how many solar panels to place and where?

I don’t plan on making an exact model of the entire topology of the ice sheet - this would probably not be possible given the granularity of data that I have found so far. However, I hope to find some averaged data about the makeup of the ice sheets in order to decide where the sun holes / solar panels would go.

c. How will you decide which months to model and integrate into the product?

To be determined. Summer months would probably be better though - as articles and models are particularly concerned with the concept of an “ice-less” summer. September is the month when the ice sheet begins to refreeze - often there is a lot of tension and discussion around the exact date it will start refreezing - so it seems a ripe moment to freeze in time.

Phototrope is a kinetic canvas that amplifies an obvious but sometimes forgotten part of our daily lives - the way light changes from season to season, throughout the day, whether inside or outside.

Phototrope constantly measures ambient light: the more light there is, the stronger and higher the leaf-like papers arch and curl, as real plants do in the sun; the less light, the gentler and lower they unfurl.

Phototrope moves in a tangible, mesmerizing way - using the material of muscle wire (nitinol) as a mechanism for the curling motion. The muscle wire is silent and responsive in a surprisingly biological way - mimicking animal muscles or the movement of plants (sped up).

It was exhibited in the Winter Show 2012 at NYU’s Interactive Telecommunications Program.

BACK SIDE:

I used an Arduino and a photoresistor to measure the amount of light.

The circuit uses a TIP120 and a heatsink. The Arduino sends a signal mapped to the amount of light the photoresistor receives. This is the “OFF” in the circuit - the muscle wires are always connected to the external power source (2.5 Amps, 6 Volts).

The muscle wire I used is .006HT “Flexinol” brand.

Each leaf has approximately 9.6 inches of muscle wire sewn into place and connected to the Arduino through a copper tape circuit.

The .006HT muscle wire’s data sheet indicates that it requires 400 milliAmps of current or 0.4 Amps. It also indicates that the resistance per length is 1.3 Ohms per inch.

Using Ohm’s Law, I have the following equation:

I = V/R or V = I*R

5V = 0.4A*R

5/.4 = R = 12.5 Ohms

12.5Ohms / 1.3Ohms = target length

total resistance / resistance per length

= 9.6 inches

If you do not calculate the amount you need in this way, you will end up feeding the muscle wire with too much power and you will burn it out.

While you may want to increase the power a little bit (here I increased from 5V to 6V because there was not enough power to make all the leaves really move), don’t increase it too much or the muscle wires will burn.

Follow this tutorial if you are interested in making things with muscle wire:

An ambient kinetic sculpture that reacts to the amount of light around it. It always pulses up and down, but as there is more light, the leaves arch higher, and as there is less light, they pulse gently up to a low angle.

In this video, the light is strong, and then I am blocking the light sensor to simulate a dark room.

As many warned me, muscle wire is a tricky material.

It reacts to direct voltage quite happily (if you have the correct equation of resistance per inch etc. in place) - but if you are sending voltage / input from the Arduino, it is not happy as the Arduino does not supply enough current. It only reacts in tiny amounts unless it is getting a huge amount of current (especially with several pieces of M.W.). It also is not happy holding its bended position for a long period of time - the most problematic thing in my last post’s proposed design.

After experimenting a bunch I decided that I want to take more time to explore this material. Instead, I am returning to initial product sketches and tried and true materials.

My goal through this project has been:

- to see where the sun is throughout the day

- throughout the year

- understand its position in terms of cardinal directions

I now have prepared my object and done a mockup using the planned materials:

- sun path in veneer, a material that lets just the right shine of light through and speaks to the concept of understanding things outside while inside -

- mounted on a base with compass rose for orienting the direction of the object / sun path (must point South for proper reading)

- base box size allows for Arduino and Breadboard

- RTC clock working happily on BB

- yellow LEDs strung up from the breadboard through a foam core pre-cut with holes matching the LEDs position in the Arc Veneer top

- sides made with veneer mounted on felt

- top / bottom spacing secured by 4 small poles

Size:

- handheld: such that an average person could wrap his or her hands around the sides of the circle while it’s on a desk or table.

I am not representing the full circle of the sun because it is this very location-specific view that I am illustrating.

Further products could explore the addition of the moon and a full circle.

Exploring the compass rose illustration… found some really inspiring drawings:

Improvements to the reaction of the muscle wire… using multiple “hour” / “month” inputs from the Arduino, filtering through the tip120

Ideas Taking Shape: Final: Process

Wed, 21 Nov 2012 12:47:00 -0500

Update:

I prototyped my initial idea for showing the path of the sun through the sky throughout the year.

This initial idea had been made up of 12 months/layers, each laser cut with the sunpath as the bottom arc and holes for each hour along that arc. These holes are according to the number of hours in that month and according to the sun’s position at that precise hour.

LEDs light up at the sunlight hour and the month (so for example, in the November arc, and at 10 a.m.).

Having shown it to a lot of people and looked at it a lot myself, I still do not think it communicates all of the information very well.

Over the weekend and the beginning of this week, I have been working with muscle wire and think it could be the right medium for this project.

The concept behind it is:

Each hour is represented by a flower petal (24 in total, per month).

On the first hour of sunlight (7 a.m. for November), the 7 a.m. position petal curls back. Et cetera until 4 p.m. when the sun sets and all of the petals that had opened will close back to their original position.

As before, the actual arc length and shape is important to me, therefore each month will have a different containing arc.

There will be a full circle of petals, but only the hours of sunlight petals will be activated.

I am going to start with One Month and prepare the full hour wheel, so 17 normal petals and 7 muscle wire petals, and build from there.

In the below sketch, the pink are the muscle-wire incorporated, sun activated petals, and the blue will always stay still as they are the no-sun hours.

Rough tests:

I plan to contain the wiring and Arduino underneath the flower, in a thin plywood box that would sit comfortably on a desk or table - or could be mounted on the wall.

A lot of thinking through the process left me in the plan to begin with just one month.

See various possibilities:

Option 1:

Muscle wire incorporated in all 24 petals (24 hrs of the day)

It is activated on all petals so that they are closed up - but as an hour gets the sun (let’s say the 7 a.m. petal), it opens - thus voltage OFF on that one - and then for 8 a.m., and so on, until we are at the end of the daylight for the day, at which point they all revert to being closed up (voltage ON)

Option 2:

Muscle wire only incorporated in “sun” petals (average of 10 - but depends on which time of year we are in)

In order to keep the no-sun petals closed, use elastic… not sure how to do this? Would it be on the tip of each petal, pulling it inward? But enough slack so that the muscle wire, when activated, would be able to resist / open the paper petal?

Option 3:

Each petal represents a different month of the year. 12 petals total. Sized according to hours of daylight for that month.

A petal unfurls when 7 am and its month is called - but maybe the voltage is analog - so the unfurl is as slowly as that days hours and this creates a feel for where we are in the day - halfway unfurled down would be halfway through the sunlight for that day -

Muscle Wire

Sun, 18 Nov 2012 14:34:00 -0500

Jie Qi taught Sophie and me about muscle wire yesterday. She is a fantastic teacher. We had so much fun! The pleasure of mixing electronics with craft… sewing the muscle wire into place, adjusting its placement with copper tape circuits…

To start with, we figured out how much muscle wire to use based on the voltage we were going to use (a 5v power source). Using Ohm’s law (V = I / R) and research as to how many amps the muscle wire takes, (we used 0.006 HT Flexinol), we calculated that our target length was 9.6 inches. We cut our 9.6 inch pieces in half to have more material.

Then we crimped the ends of the muscle wire because it is easier to solder the crimp than to solder the tiny end of the muscle wire.

Next we soldered the muscle wire into place on the copper tape circuit. It’s important to try to have the muscle wire tightly in place so that when you apply voltage and it tightens further, the interaction is swift.

We also sewed the muscle wire into its place in the paper so that the paper would be fully reactive rather than just pulling at either end.

Above you see the sewn paper / muscle wire, and the copper tape circuit connecting the two pieces of muscle wire (the total length of 9.6 more or less, to resist the 5V coming in properly).

Another circuit photo - this is the back of each panel:

Applying voltage, curling up!

Sketches of how this could be… the arcs, where the arcs could sit, how the LEDs would climb the legs of the arc.

More details, thinking through the months… front view and side view:

Maybe having a tilted based would give the same understanding of the change in the arc / day etc?

I found a website that models the path of the sun throughout the year to model solar energy options.

It produces drawings like these:

I traced these and created thin arcs, with wholes where the hours are. I am lasercutting each arc, putting together a small arch structure where the LED wiring could fit behind the arcs and the LEDs would shine through each hole at the appropriate time.

Here is that sketch, with the arcs in month order. See how the arch changes throughout the year.

It makes more sense to go with an order that reflects the order of the sun throughout the year though:

I also tried piling up the above arches - one on top of the other - out of curiosity - though this would not be a feasible design because the light would not come through to the front if it were December or January.

Subtract…

And then the Arduino component of the clock - using Processing first, just to get a feel for the parsing, and then the Real Time Clock module. My tape tags show that the date is parsing correctly (It was 7:30 p.m. and November when I was testing).

FINAL PROJECT:

For my final, I am going to make a small, desktop sundial - season - clock.

There will be an arching wire for every month with LEDs along the wire. The LEDs mark the hours throughout the day, along the arch of the wire, mirroring the sun’s path through the sky each day. This description of the sun’s path is detailed - if it is a new month, the LEDs along a new wire will light up - demonstrating how the sun’s path changes throughout the year.

The structure would be wrapped in rice paper or another slightly textured paper to mask the wiring underneath and diffuse the light from the LEDs slightly - such as the tea filters I used in my Light Jars.

My rough mockup / starting to understand the wire spots through the year.

For example, currently the sun rises south of east and south of west - not exactly in the east or exactly in the west.

I am deciding between several formats:

1. Full detail: every month, every hour. (12 arches, approx. 144 LEDs)

2. Part: every month, but rather than hourly, it would be chunk of hours (morning, middle, afternoon) (12 arches, approx 48 LEDs)

3. Part: seasons, every hour. There would be an arch per season, and LEDs lighting up every hour. (4 arches, 144 LEDs).

4. Detailed LEDs: for each part of the day, the LED colors would have variations: white+yellow (early morning), bright yellow (midday), or white/yellow/purple/blue/red (sunset).

5. Detailed LEDs + Internet info: if the day is cloudy, rainy, the LEDs will be yellow throughout the day. If bright and sunny, the LEDs will be white throughout the day. If the pollution index is high, the sunset colors will be particularly rainbow-like (according to the theory that the more polluted the day, the more glorious the sunset).

Rough trial: LEDs lighting up according to time of day / month.

This would live on desks, in living areas, in schools, and teach us about our environment at the same time as it added information to our days in an ambient, subtle way.

Other ideas on sunlight:

Untitled (for the Sun) by Jim Campbell - a clock that displays time as a percentage.

“Beginning at 0 at sunrise, the five-digit display shows the percentage of daylight already spent, reaching 99.999 at sunset… because time is measured by the length of daylight, the clock (or ‘time’) runs faster in the daytime in the winter then in the summer.”

Major takeaways…

Kaitlin has a combination of personal, artistic, inspiring objects in her apartment. She feels the need for more space because she would like to separate some of the clutter “Trash” that is not trash and the personal (clothing mostly).

Recommendation…

Create a separate set of drawers / shelves for artistic gathering to capture the “studio” gathering. Keep the simple feel for the rest of her life.

MUSEUM MANIFESTO

Exhibit priorities:

- Mystery

- Secrets

- Sense of discovery

- Look twice / suspension of disbelief

- Come away with a story You Learned - something to write home about

- Make a connection - have the “this reminds me of that book” (or article or theory or film or other piece of artwork or thing that you are working on)…

- Space to question what you see and its description - wonder more, delve deeper (the tiny library/nook at the Guggenheim allows you to read through beautiful books about the current exhibition)

Museum atmosphere:

- As a beautiful library entrance and its reading rooms elicit a feeling of awe, of inspiration to be a scholar, as a beautiful religious building might elicit feelings of devotion, so should my Museum elicit feelings of awe, inspiration, maybe devotion, as well as excitement and curiosity

- But the above (library, church) also allow for simple contemplation. And my museum will have places for this in and among the exhibits (for example, the Frick’s courtyard, the Met’s Astor wing / round room on the dinosaur floor, sea creatures hall with the parquet flooring where the kids sprint around and the grown ups lie down if they want to).

Specifics:

- For discovery: take MOMA’s giant suspended helicopter as an example of how to play with the space, bring in objects that are specific to a museum (not everyone gets to stare at a helicopter close up - unless you go to MOMA!), display them in a surprising way that make people think twice, look twice at the objects around them.

- Natural light: again, MOMA’s use of windows into the city from high up, making you feel as if you are still in a bigger environment (the city) rather than entirely separated from the outside and outside life…

- Comfortable couches, and many of them. Some right in front of a piece of art.

- Nook / reading rooms in the exhibit space itself rather than separate hall or floor - these allow for deeper delves into the subject matter and supplement simple captions and exhibit introductions on the wall.

- Nook / cafes on each hall or floor.

- Speaking of floors, the museum will have four exhibit rooms, a cafe and a restaurant. Plenty of natural light. Garden courtyard in the middle. Each room is clean (white paint, nothing else than the art, couches, nooks built in to room) - rather than richly decorated (like the Frick) unless the exhibition is about interior decoration.

- Friendly, warm security guards and overall staff - curious and interested in provoking discussion on the current exhibit.

- If an exhibit needs, it can close the curtains over the big windows / add japanese-like screens to change the space - the “four big rooms” can be altered. The idea behind “four big rooms” is “not too big!”

Additional:

- This museum will be a place to go with a friend, to stop by, to put your feet up when you have an hour and are in the neighborhood.

- Therefore, hours will be until 9 two nights a week (thursday, friday) (to accommodate post-work people).

- There will be concerts in the courtyard when the weather permits.

- There will be film screenings at night according to the exhibit theme.

- There will be workshops where artists teach a craft that has to do with that theme (for example, if the exhibit is about “The Progress of Love” and one of the pieces in the exhibit is a hand-woven basket that wives made for husbands in 1792 to show their love (making this up), then there will be workshops about how to make those baskets.

- The website will be simple - hours, directions, and a tab to some web-specific specialties - whether this is audio or video or more photographs or an interesting collections browser, slideshows (top ten outfits curated by a Fashion Magazine Editor for the exhibit on women’s fashion during WWII, for example).

In the end, I think I like the way it looks without any light at all (see picture 3), but many lessons learned:

1. Capitalize on the potential of mobile, different leaves actually floating together

2. Plexiglass distracts from the leaves, the element I most wanted to evoke

3. Lightbulb problem: the first inspiration of leaves along a long fluorescent tube would have worked better

4. Room for improvement. Still intrigued, but looking forward to entirely reworking the idea.

After collecting maple leaves and branches,

I preserved them in a solution of glycerin and water and then mounted them in plexiglass.

I played with the shape - trying a hexagonal shape as below -

Instead, I returned to the planar shape that initially had caught my eye in the maple branch structure.

I then worked on the lighting part - changing the wiring from a straight plastic insulated cord to a rope -

Though I really liked the glass fixture that I found to work with, I decided to go back and simply use the typical clear cord instead because of the aesthetic of the clear plexiglass that I was working with already.
