Was up late last night working on the paper and staining and using the cnc FOR something unexpected. cutting the holes out of the bottom for the light! LOOKS great! cant wait to put it together! hopefully today!

CLARIFICATION

For, those who don't or seem to not comprehend what I'm saying... Hopefully this helps

Router tore this one up =o/ had to switch to table saw. However, these are the inside edges. 1st edge is where the plex will fit in, 2nd edge(large one) is to put a backing on the frame

Where the light will go..... So you will have the front edge and the back edge and that has to fit in between. Therefor, I had to make the front inset small. Meaning..... The cnc idea can't work. Once these pieces are put together in frame form... the plexi will be sandwiched inside... therefor the cnc depth for the front of my box/frame wont give me what I am looking for

Pieces cut!

MY PIECE

Cut my wood yesterday. Having 2nd thoughts about the cnc.... they look so good and the intended dimensions had to change based on weight. Also the light is big so there's not much room to give the cnc the dimension i envisioned. the router must be dull because it was eating my peices sooo we used the table saw =o)

need to assemble, seal, and sand(again). Might focus on ceramics since I need 8 cups done and am leaving early for an interview this week =o)

Today, I didn't get on the CNC or put my frames together because I fell in love with a light cedar so drove to Cinci to get it and got pretty lost, surpriseeeee!

Research

Where would we be without the steam engines?

-with out mechanical tools such as planers, pointers, Mills, Drills, Grinders, Presses, Saws.

Now tools such as those are combined and ran by computers to get high precision and quality

LASERS AND LASER CUTTING

laser cutter works by directing the output of high power laser, by computer, and the material to be cut. The material then either melts, burns, vaporizes away, or is blown away by a jet of gas leaving an edge with a high-quality surface finish.

In 1917, Albert Einstein theorized the principle of a laser, when he came up with his theory of stimulated emission. Einstein’s theory said that an excited atom in isolation can return to a lower energy state by emitting photons, a process he dubbed spontaneous emission (http://www.ehow.com/about_6391803_history-laser-cutting.html)

http://www.olympusfluoview.com/java/stimulatedemission/index.html- shows the stimulation

In 1960, Theodore Maiman Developed the first working laser at Hughes research la. It was diescribed as “a solution looking for a problem.” So many companies began to look for that problem. Then in 1971, one of the first well known uses was the laser printer.

First experiment in laser material processing was conducted in may 1967 when peter Houldcroft used an oxygen assist gas to cut 1mm thick steel sheet with a focused CO2 laser beam. This was one of the first 2 axis moving optics CO2 laser cutting machine built in 1975 made by Bystronic, similar to what we use today.

“With the correct laser power settings, the industrial laser can cut cleanly through mild steel to 0.75 inch, 0.5 inch of stainless, as well as aluminum, bronze, and titanium. Industrial laser cutting machines are the fastest machining process for flat sheet and plate materials. With the utilization of high intensity light surrounded by a high-pressure gas, many geometric complex contours can be manufactured without the need of hard tooling. A by-product of these laser cutting procedures, edge quality rarely needs secondary processing.”” most importantly, the speed is normally faster than other profile cutting methods.” (http://www.ehow.com/about_6391803_history-laser-cutting.html)

CATIA: (computer aided three dimensional interactive application) a multi platformed CAD/CAM/Cae commercial software suite developed by French company Dassault Systemes and marketed world wide by IBM

The software was used in the 1970’s and the 1980’s to create dassault’s mirage fighter jets, and then used in industries to digitally design and manufacture machines like in aerospace, automotive, and shipbuilding. Before it moved to these industries and became CATIA it was CATi but once it partnered with IBM it became CATIA in 1981

3 D Printing: used to construct objects by printing successive layers of material to form an object. Works by taking a 3D computer file and making a series of cross-sectional slices. Easch slice is then printed one on top of the other to create the 3D object. “It works like this. First you call up a blueprint on your computer screen and tinker with its shape and colour where necessary. Then you press print. A machine nearby whirrs into life and builds up the object gradually, either by depositing material from a nozzle, or by selectively solidifying a thin layer of plastic or metal dust using tiny drops of glue or a tightly focused beam”

-Leonardo Da Vinci connection to 3D Printing- "To make his case Reti compared Leonardo’s drawings of basic machine and kinematic elements with the basic list of ‘constructive elements’ found in Reuleaux’s Kinematics of Machinery (1876).

One such comparison is the slider crank mechanism. Leonardo da Vinci drew several designs of slider cranks and also appeared to understand the nature of kinematic singularities through these drawings"

-Also Introduction to kinetic History.

"There are several rapid prototyping technologies, including laminated object manufacturing (LOM), selective laser sintering (SLS), photo polymerization (stereolithography, SLA), and fused deposition modeling (FDM)"

FACTS

http://www.designnews.com/article/511989-Urbee_to_Be_First_3_D_Printed_Car.php

“At the Massachusetts Institute of Technology (MIT), Peter Schmitt, a PhD student, has been printing something that resembles the workings of a grandfather clock. It took him a few attempts to get right, but eventually he removed the plastic clock from a 3D printer, hung it on the wall and pulled down the counterweight. It started ticking.” Started with making most prototypes, however now it is creating 20% of the final product. “3D printing allows for a great deal of customisation. Indeed, in the future some see consumers downloading products as they do digital music and printing them out at home, or at a local 3D production centre, having tweaked the designs to their own tastes” Stratasys is even trying to print a car!

My PROJECT 101

Let’s Cut In

My goals are to create something that I can use upon leaving college. I wanted to give myself the opportunity to learn new tools. I started off thinking about doing a bed board or a lamp, but I soon realized the limitations of our schools laser cutter machine. However, not all of the laser cutter machines have the same size and cut limitations. This made me think about how uncommon these tools are. It’s not like your average printer that everyone has, or availability of printers that extend the limits. I choose to forgo these ideas because I didn’t want to substitute cut metal nor have my light be a “jigsaw” puzzle (I wanted a big light). So, my project idea changed into a combination, a light box, and from there I got excited while designing it and buying the materials and wanted to do picture frames that matched it.

My materials are wood and plexi glass. What I am unsure about and in need of some inspiration are plexi applications for color/surface change as well as how I want my light and if I what colored lights. Currently, I have my plexi glass cut. Some issues I had with it are: etching, cuts not going through enough, tight parts of my letters releasing differently. For the etching, my material must have had a bow in it or a difference in the plastic coating because a vertical part didn’t show up as deeply etched, some was even hard to see. The cuts on one of my pieces didn’t go as smoothly as the others; there was more effort in pushing it out. So, I waited till a later date to push it out finding it harder to push it out, leaving me to believe the plastic was still at a different temperature when I was pushing it out, then cooled again. That piece will have to be remade due to cracking during the “pop out stage.” For my letter cuts some of my o’s kept there middle, however for others it popped out. Smaller connections do have their limitations, however the detail that a laser cutter can accomplish is pretty impressive.

My next step is creating my “boxes/frames” 2 of them I would like to use the CNC on to create an interesting surrounding for my intricate laser pieces. I’m taking an image and using rhino to project its depths onto my piece. Currently, I have an idea of what I want, However, with the limitations of the CNC I could very well be surprised. CNC’s are based on bit size, speed, and even minor details like the vacuum being on or properly adjusting your piece at 0,0, etc. I just hope if it’s not my outcome that it’s a sweet serendipity. Although, having experience in the CNC will help me achieve my initial goal.

After that is picking a plexi-glass color or a colored background. Writing this I got a random idea of using a transparent material and printing on it for the pictures. I remember Sarah Pytlik doing and think it could be very intriguing to my piece. With that I can also light my picture frames, however, I worry about glare.

My project has already had some complications, some that were avoided and others that couldn’t be. With each time I use a machine I become more familiar with potential complications and can assess those before hand. For instance, when I cut my piece again I’m going to run the cut twice as well and make sure the surface is completely level.

I think what this process can teach is that machines like this offer us great opportunities, but they also have flaws, much like humans.

Project

Ugh, You guys my piece broke today, I was popping out my laser cutter letters and it snapped my piece. I hope jeff can fit me in soon! I have to buy my wood wednesday(steal aaron's car) and then cut and put together the "box/frame" thursday morning.... then experiment with my idea on the cnc thursday night!--- not a grid anymore.... but im going to surprise you =o)

but this was my inspiration:

Check one, issue one

My boards are cut =o) they look SO good! Next step Get wood. The plan is get that Sunday.

Heads up on the laser cutter make sure your board is even, no bowing or big difference with the plastic..... mine faded in the etching in one part due to one of those issues they think....

My project

I'm sitting here waiting for the laser cutter. I'm really excited about what I have. I have created 3 boards each 12"X24". Initially, it was going to be one, But then I had these extra incase I wanted to create layers. I changed my mind on the layers once I did my first design. I wanted the lyrics, and I did that. Then I wanted the back to have an some sort of design, so I created a repeated word in the back. My other 2 boards I created picture frames, kind of, it will hold 3 pictures and then it is designed with lyrics as well. Once I have these done I have to think about how I want my boxes that hold them to look. While Im thinking thick so they can act as shelves too... I am also thinking perhaps more of a grid hold where parts are cut out. Or slightly combined the two and use the CNC and create a grid design on the sides and have a solid top.... however I want it to be smooth and the CNC takes forever to achieve a smooth surface.

Questions for you.... best way to frost plexi... I was thinking frosting the back(the side not etched on)

Addressing the Questions

What kind of application would thermocrotic paint have in architecture?- Currently, I don't see it as a need. However, I could see it being an exterior paint that changes as the temperature changes. Interactive to the enviroment and the human eye

Arduino- Do you have a better understanding of how sensors work? -Both hardware and software. I don't necessarily get how it works. Like would I be able to recreate that based on the knowledge I have? no, however, It was crazy interesting to see it be such a simple concept to mechanically/light controlled

How could you apply processing to a component of a building? I think the program itself is a form of 3D modeling.

How are the hexbugs we saw today different from the ones that are remote controlled? Is there a different type of interaction? Where else do you see these kind of sensors applied. Remote controlled bugs are defined by what we tell it to do, they dont interact with anything but that remote. while the hex bugs are interacting with its space as well as we can get involved in changing the bugs outcomes. On the top of my head I can't think of any Touch sensors, which is probably a sham since the technology is so intreguing

http://webblick.de/twists_and_turns/twists_and_turns_videoprevEN.html

ITs a reaction to the architecture itself(different ways to define it), the environment(surroundings), and the people.

TO me its an artistic interaction

Smart meter

SMART METER

"She says the meters are saving her money on lunchtime stops, because she reinserts her card when she's ready to leave and gets a refund for unused time.

"The nice thing is I don't have to carry change around in the car or in my purse," she says.

The meters — some of which also take coins — include solar-powered devices that take credit or debit cards, meters that can be paid by cellphone, and meters linked by wireless networks that can be remotely controlled and alert officers to parking violations, Vanderhoof says."
