The next logical extension of the Laser Collage process is something I call The Eric Carle Method. Children’s book author Eric Carle is known for his collage are using his hand painted papers. The main difference is that you are adding paint to the process rather than using ambient papers or recycled materials for the collage art. I had a clear idea of what I wanted in this design and drew the squid and submarine in Adobe Illustrator using the pen tool. That step took me at least three hours. I used a Gelli Arts soft monoprinting plate to roll acrylic paints onto and made the color combinations I wanted for scene, aiming for a red / blue /yellow primary color scheme. This version pops out and seems more playful. I may try a version with darker colors and low intensity hues to see if it looks more realistic. Today, I was just aiming for a fun picture. My paper was an 80# weight cardstock with a hard, smooth finish. This paper held the acrylic paints well with little to no warping and dried fast. I used the Epilog Mini laser to cut and etch my drawings. The vector cutting was at speed 20 / power 25 / hz 500. Only the slightest edge of the design had a sign of the laser, literally just the plane the thickness of the paper; viewed from above there was no visible scorch. The acrylic paints had some resistance to being etched and I used speed 100 / power 50 to etch the eye and a few lines. Matte acrylic gel medium glued the arranged layers together. Boards and wax paper were helpful to press the art flat. I used a Micron pen to fill in the etched lines on the body and for the eye and some thinned white acrylic paint for highlights and reflections. I’m really happy with how my giant squids came out. This was unfortunate for anyone who was at the space today because I went around with them when they were done. It’s not often that someone comes up to you and asks, “Have you seen my squids?” File that under the heading “Because: Hackerspace.”
Inventables donated a ShapeOko 2 CNC Router “The Works” kit to Pumping Station:One, and we’ve been doing a group build over four sessions so far. It’s been a chance for people to learn about open hardware and CNC firsthand from the ground up, and participate in making PS:One’s next machine. We’ve had participants with various levels of experience working together, and I think everyone learned something new.
During the first session, we assembled wheels and bearings, and attached them to plates for the x, y,and z axes. We started the next session with parts that looked like this:
The instructions describe the z-axis assembly as the most intricate, and they’re not kidding. It took a lot of fiddly work and some mistakes to get here:
Thank you to everyone who helped so far! Our next build session will be Thursday, August 28th at 7pm in PS:One’s shop. We’ll be testing the motors, troubleshooting, and sending the “hello world” job. Come see the machine move!
Thank you Ron (I think) for the Session 2 photos and Allen for the Session 3 photo.
Every artist hopes to come up with an original idea, to be on the forefront of the next big idea or movement. This is hoping against the odds as the past two centuries have seen an explosion of movements, styles and schools of thought that rained down in Western art like a meteor shower. Fauvism, Cubism, Futurism, Surrealism and many other modern movements would originate, peak and dissipate rapidly, lasting a few decades or less. World Wars arose and crushed other movements like Romanticism or Der Blaue Reiter. There are many forms of art that we can reach into the past and mine: appropriate and carry on with. In fact, schools of American Impressionists are still working in different lineages since the 19th century from William Merrit Chase, John Singer Sargent and other painters. Waves of more recent artists have imitated Picasso and Warhol. For the contemporary artist hoping to create something unique, there is very little chance of inventing something new.
Current technologies are opening the door for innovation. Many times, I am seeing where maker technologies are being used to vary production of traditional physical media arts and crafts. Laser cutters are being used to etch intaglio printmaking plates, textiles are incorporating electronics and lights, robotics are animating sculpture, and digital media is widely available. Video, animation and interactive arts are now accessible to most of the general public. It’s an exciting time to be involved in the hacker/maker culture.
I may have come upon an idea that can become an art style uniquely ours: Laser Collage. I have always enjoyed collage for drawing on images and materials readily available around people. At its most basic level, the only thing needed to create collage art is some form of glue or paste. Good scissors, a razor blade or hobby knife are helpful. Throughout art history, most fine art collage works have followed their siblings in painting and drawing, largely staying within the bounds of a rectangle or square. Contemporary painters such as Elizabeth Murray, Frank Stella and Ellsworth Kelly set their abstract works free from the tyranny of the rectangular border. Now artists in the hacker/maker community can liberate the collage from the rectangle.
Laser Collage innovates through using two things well loved in the hacker/maker community: digital vector art and laser cutters. By using a vector design, the exterior borders of a collage art can take any form. Art works can have further elements by using raster etching as well as the vector cutting abilities of the laser. Artists can utilize recycled materials. I am excited by the possibilities for this medium. Functional and three dimensional designs are possible beyond flat two dimensional art works. Laser Collage is an art style that frees the collage art to be any size and shape. This is an art form that can be uniquely ours.
My experiments with these samples were basic in materials. I used recycled chipboard (i.e. common food packaging like cereal boxes) and a simple glue stick. I avoided PVA [polyvinyl acetate] “white” glue since it is similar enough to PVC to be a possible problem with dangerous fumes from a laser. Any glycerine and wheat-based adhesive like glue sticks, YES! Paste or acrylic-based adhesive like gel medium should be safe for laser cutting.
Using the Epilog Mini 30W laser, I got an excellent cut through the variable thickness layers of paper and chipboard using a vector setting of speed 15 / power 100 / hz 2500. The edges have a little scorch, so you may want to adjust your cutting power or increase the speed. Raster etches were at speed 40 / power 100. Etching has interesting potential for etching your collage in a fashion that lower layers reveal different colors in the design. My approach was to cover the chipboard surface first in collage elements with my glue stick and then place it in the laser cutter for cutting and etching. The artist controls the materials used, color palette, range of colors, form of the collage pieces, flow of the collage design, number of layers cut by the laser, laser etching elements and the ultimate size and shape of the border.
Creators without access to a laser cutter could use vector designs using an electronic cutter like a software hacked Cricut, a Silhouette cutter or similar machine. I have often seen owners of these tools cut elements to incorporate into collages, artist books and paper arts, yet still retain the linear borders of a square or rectangle. Shaped collages would be restricted by the width of the cutting machine which is usually around 12 – 15 inches, whereas laser cutters tend to have larger cutting dimensions. I am most excited by the potential for the medium through laser cutting technology because a laser cuts details a lot finer than a metal blade can and etching adds more depth to the design.
Laser Collage is my humble offering to the continuum of Western art history. Maybe I will be the only one interested in this form but I am putting the concept online hoping other people will want to try it. Mixed media elements including paints, markers, pens and pencils can also be easily incorporated. Feel free to experiment with the process on your own and please respond if you want to show your work in this medium, if you have any discoveries or develop a variation of the technique.
It’s time for another movie night! This is our third tech-documentary related movie night, and we will be showing Revolution OS. “Revolution OS is a 2001 documentary film that traces the twenty-year history of GNU, Linux, open source, and the free software movement.”-Wikipedia
Since LinuxCon Chicago ends on Friday at 5 PM, this is an excellent after-con event to bring your friends to!
There will be popcorn and feel free to BOYB.
Where: Lounge of Pumping Station: One
3519 N. Elston
When: Friday August 22, 7:30-9:30 PM
Doors open at 7 PM
This event is open to the public.
NERP is not exclusively Raspberry Pi, the small computer interest group at Pumping Station:One in Chicago. NERP meets every other Monday at 7pm at Pumping Station:One, 3519 N. Elston Ave. in Chicago.
Tonight at NERP, Sevin Straus will give an introduction to NVIDIA’s CUDA architecture. CUDA uses a cpu to farm out pieces of a task to the parallel processors in a video graphics chip (GPU). [more below]
[img: large-video-dynamic-parallelism-2-en.jpg nvidia.com]
Nvidia wants lots of developers to know about CUDA. To that end, they have put together a complete development environment. In the best of all worlds, the environment should be usable on Linux after simply running “install.sh”. It’s never really that simple. Sevin has put together a working develpment system targeting the Jeston development board. Tonight he’ll show us how he did it and some of the included demos.
A sense of what CUDA is about would include these thoughts collected from various parts of the CUDA website:
CUDA® is a parallel computing platform and programming model invented by NVIDIA. It enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU). A GPU consists of thousands of smaller, more efficient cores designed for handling multiple tasks simultaneously.
GPU-accelerated computing is the use of a graphics processing unit (GPU) together with a CPU to accelerate the compute-intensive portions of tan application to the GPU, while the remainder of the code still runs on the CPU. From a user’s perspective, applications simply run significantly faster.

Lucid Dream: any dream in which one is aware that one is dreaming.
A few of us got together to discuss lucid dreaming this past Sunday. Among the things we talked about were; the benefits of lucid dreaming, the possible evolutionary explanations for dreaming, and personal lucid dreaming experiences.
We left off with a group challenge to try at home:
1. Wake up earlier than normal.
2. Play ambient tropical ocean sounds. Click here for ambient music or find your own.
3. Go back to sleep with the ambient tropical sounds playing.
With this experiment, we want to see if we can affect our dream’s setting through audio. You may be able to hear the sounds in your dream, which could place your dream on a tropical beach.
I hope to use these meetings as a way to explore how we can use lucid dreaming, with intention and purpose, to improve and explore ourselves. How can we hack our dreams to get more out of them? Can lucid dreaming become part of our creative process? Join us at our next meeting and feel free to try out the group challenge. We will discuss our experiences with this experiment together.
Next Meeting: Sunday, Aug 10 at 7pm in the kitchen
