Light Wk 5: Observation

 

Monday, 3/04/19, 4:30 PM – 6:30PM
Brooklyn, New York

The window faces north. When the sun is still up, the gradation in the sky color and the moving clouds are obvious despite the translucent curtains. Through the curtains, you can roughly see that the sun must be reflecting on a building (located on the bottom right of the window frame), causing an orange globe to sporadically show up. Outside, the sky becomes warmer in color and then gradually changes in color temperature at around 0:19 seconds in the clip. The cold color when the the sky goes into night time makes the room’s interior appear a sickly yellow instead of a warm yellow. This yellow is noticeably more “unnatural”,  as it is is coming from the room’s led lights. In this time lapse, the shift between cold and warm colors, natural and room light are markedly different.

My favorite parts of this timelapse is noticing the gentle colors reflected onto the smooth desk. I especially like the blueish white color from the outside that is reflected through the curtains and onto the reflective desk and keyboard.

Energy Wk 4: Battery

Record the specs for 3 batteries: chemistry, voltage, and capacity (if capacity is in amp hours, can you get to watt hours?).

Energy(wh)  =  voltage * current * time

1.) iPhone XS Battery :

  • Chemistry: lithium ion
  • Voltage: 3.8v
  • Capacity: 2.658 Ah
  • Watt hours: 3.8v * 2.658Ah = 10.1004 Wh

2.) Headphones Battery:

  • Chemistry: Li-Polymer
  • Voltage: 3.7v
  • Capacity: 180mAh
  • Watt hours: 3.7 * 0.18A = 0.666 Wh

3.) FitBit Battery:

  • Chemistry: Lithium Coin
  • Voltage: 3v
  • Capacity: 163mAh
  • Watt hours: 3 * 0.163A = 0.489 Wh

Subtraction Wk 4: CNC, CAD, CAM

I followed along with the skill builder tutorial. There were many hiccups along the way. Overall, great learning moments from this skill builder.

1.) First, I made the drawing in Vectorworks. In hindsight, I did my first sketch wrong. It took the help of Professor Ben to get it to be right.

Remember for future:
* File needs to be exported as version 2010
* The shape needs to be placed close to the 0,0 in the top right quadrant
* Don’t use paint bucket, just have the individual shapes for the pockets and contours

Here is the Vectorworks of the version that I did wrong:

Here is the version that is right:

drawing_v2_right

2.) Next I went into CAM and adjusted the settings to match the one in the tutorial and my bit size. After the first cut, I realized I did not set up the settings properly.

* Note: Remember to make sure there is breakthrough. Also make sure that when you view the 3D version there are the lines that indicate the layers for cutting. The first timeI did it was wrong and only showed one line (so the “blueprint” version looked flat).

3.) I saved with the G1 Button and it turned the file to a NC file. Then I took the usb to the desktop with the CNC program.

4.) It took me a long time to figure out the colette and bit situation. This took some asking around, especially since I did not have the right size bit. I had a 1/2″ and a 1/8″, which was too small for any of the colettes. Eventually, I ended up borrowing a 1/4″ bit (thank you Nick!).

I also screwed down the plank of wood.

5.) Once the bit was in, I tried zeroing. This part was straightforward but I forgot how to move the x axis. I had to stop and review notes to figure that out. Eventually, it was honed and I was ready to select Zero All.

6.) Next, bit was the exciting part of finally cutting the wood with the CNC!

The issue was that it stopped after only cutting into the wood a few times, so it just made a small dent of the outline. Below is the image of the first cut.

7.) I went back to the CAM to try and see what was wrong with my settings. At the time, I assumed it was most likely because of my settings in CAM.

I readjusted the contour settings, and realized that it was supposed to show something that showed the multiple layer cuts.

8.) After readjusting, I repeated the zeroing steps. I couldn’t remember exactly where it started so the placement of the cut lines is different this second try. I also didn’t change the piece of wood, because I consider it practice.

9.) Second time it did cut through thankfully. One issue was the piece was popping up as it was getting cut. This caused the bit to drag along the surface of the not wood that wasn’t flat anymore. I had to pause the CNC and screw down the parts that were becoming raised.

10.) Final cuts were made! One side looks awful, but the other side was not as bad.

Energy Wk 4: Solar, Cool Bunny (wip)

pashmy

Cool Bunny Project Objective:

  • Solar energy will power the wireless communication device and temperature/humidity sensor. When an unhealthy (for the bunny) combination of high temperature and high humidity is measured, the feather RF will communicate to the other feather RF to use the relay to turn on the fan. The fan will then be used to cool the bunny (yay!).

  • Project plan:

Light Wk 4: Observations

barnes and noble cafe

Monday, 2/25/19, 12:54 PM
Barnes & Noble 3rd Floor, New York 

This Barnes & Noble faces south. On a sunny day, the light casts highlights on the sides of the cafe goers faces. The placement of the window decides who receives the sunlight and who doesn’t. With this bright sunlight, I wonder why the lamps are still on. When I was in there, the light fixtures didn’t make a big difference in that area. Most of the light in the cafe section is overpowered by the sun’s light, which casts a wider range within the room.

Mala Project, New York

This moment was as overpoweringly red as it looks in this photo. The red color is coming from many different sources: the unnaturally colorful neon lights and the red lantern shades above. The red is further emphasized in the space because the light sources are reflected on these reddish-brown bricks, which reflects the red even more. The way neon emanates light is spectacularly unnatural and fluorescent. For example, the neon light that is highlighted in the poles and waxy wood surface of the ceiling’s beams are a highlighter pink. And the neon itself is so bright that it looks white in the photo. I especially love the powerful glow that surround it and the reflection it casts on the surface in front or back of it ( I can’t tell).

 

 

Light Wk 4: Sconce (wip)

Another Possible Project Idea:

meditation_light_idea

Possible Project Idea (still not sure):

A pair of sconces that turn on when there is a key placed on the handle and turns off when there is not.

Potential ideas for dimming: when person is closer to the fixture, the light dims. when person is further from the fixture, the light brightens. when the lights are off in the apartment (room light), the light turns off

Disclosure: have another form for the same idea.

Sketches of Ideas/ Mechanisms:

Coding Process:

  • Played around with the High Watt LEDs

 

  • Played around with Ultrasound sensor as a possibility

Fabrication Process: 

Tried to see how this key switch would work if I went with this direction. The switch handles would have to be fabricated, since it needs to have a way to hold the keys well.

Subtraction Wk 3: More Other Mill

For this week, I tried to do inlay acrylic pieces with The Other Mill machine. I decided to do groovy hair clips/ pins using the acrylic scraps from last week. The goal was to aim small and do something I would want to sport!

Cut my scrap pieces from last week into more manageable sizes.

acrylic_scraps

First, I sketched out some simple designs. I had to tweak the designs because my bit size wouldn’t be able to handle any fine lines.

I then made individual Illustrator files to then import into Bantam Tools. I’m still way more comfortable in Illustrator than in Vectorworks. I don’t find doing offset and using the pathfinder tool is difficult in Illustrator, so I stuck with it.

Bantam version is ready. I located the tool to get the bit to zero in on the surface. Then I honed it. Double stick tape was applied to the back. Milling time begins!

Uh-oh, halfway through the double stick must have loosened and the acrylic piece came off the bed.

I needed to clean up the machine and start over again. This is not ideal because as you will see it will never be placed in the exact position as before.

After the 2nd try, I finally finished the outer white cut.

Onto the black acrylic for the center of the groovy circle now!

black_acrylic_now

I ended up having to do 2 of the black circles. Since the flower circle was not cut exactly as designed, the inlay did not fit perfectly in the hole. To solve for this, I made another bigger black piece for the bottom of the flower pin. This would be where the pin sits anyways.

After cleaning up, I glued the 3 parts together.

This did not turn out ideal because of the imprecise inlay, but I am hoping that sanding and waxing the acrylic will help a lot.

Finished pin!
