Art, Fabrication, and the Endover Puzzle

Posted Dec 1 2011 by in 3D Printing, Digital Fabrication with 2 Comments

Also known as “The Cube,” the Endover sculpture is a kinetic, geometric piece of art that is located on the campus of the University of Michigan. The picture below shows Endover, but its moving elements are best seen in this video.

I built a 3D puzzle inspired by the Endover sculpture. The video that follows shows the puzzle being created on an Up! 3D printer. The pieces of the puzzle were built in FabLab ModelMaker and, when fabricated, combine to form a cube like Endover (see 00:48 to skip to the the final cube).

I envision a couple of engineering tasks hidden within the replication of a scaled, puzzle-like version of Endover. These engineering tasks may or may not be appropriate for elementary students, but I am currently in the brainstorming/prototyping phase. My partner teacher, Paula White, wants to develop some lessons that focus on spatial visualization, surface area, and volume.

  1. The creation of a 3D puzzle that, when completed, forms a cube. Paula White and I have developed a preliminary activity that uses colored cm cubes to scaffold the creation of digital and physical puzzles like the one in the video.
  2. The creation of a 3d puzzle that, when completed, forms a cube that can balance on one of its vertices. This would definitely be an advanced engineering design task, because it focuses on both the parts as well as additional design criteria and scientific concepts like gravity and friction.

In the meantime, I need to figure out if I can create an Endover puzzle that can balance on a vertex. The one in the video does not!

I put my design on Thingiverse if you want to 3D print a version of your own.

EmbedPlus Test

Posted Nov 27 2011 by in Video with 0 Comments

EmbedPlus is a tool that I have needed for quite some time. The ability to quickly navigate within a video to different time spots is something that the YouTube timecode feature lacks. So far, EmbedPlus looks like a pretty useful option for screencasts and personal projects.


Use the “Previous” and “Next” buttons to navigate to the following spots in the video.

  1. “Print and Cut” Button
  2. Place Card Stock on Carrier Sheet
  3. Load Carrier Sheet into the 2D Fabricator
  4. Final Configuration Check
  5. Detect Registration Marks
  6. Initiate Cutting
  7. Eject Carrier Sheet
  8. Peel Carrier Sheet from Card Sheet

The Simplicity and Relevancy of “Making”

Posted Nov 3 2011 by in Make To Learn with 0 Comments

If I had to identify two people that I might ask to teach me a thing or two about “making stuff,” it would be Slater Harrison and Arvind Gupta.  Both Slater and Arvind have a lot of pertinent, inexpensive ideas for STEM-related activities that feature “hands-on” work with materials.

Slater Harrison (aka, The Science Toy Maker) offers the following  activities on his website, Science Toy Maker:

  • Static Electricity Flyers: The scientific magic of hovering grocery bags seems like a fun way to explain static electricity and positive/negative charges.
  • Walkalong Gliders:  Explore aerodynamic lift with gliders that seem to never land.
  • Put-Put Boats: Although metal cans, scissors, and fire are potential hazards, building a put-put boat connects to physics and steam engines.  Plus it is pretty cool.

Arvind Gupta talked about his creations during a TED talk, and he provides examples and instructions on his Toys from Trash page:

  • Straw Pump: Build a simple water pump using straws, beads, and small metal balls.
  • Floating Forks: Can you make two forks balance on a toothpick?  Arvind can show you how…
  • Paper Protractor: Create more than a dozen different angles by folding a square sheet of paper.

Gears

Posted Aug 11 2011 by in Digital Fabrication, Math with 0 Comments

I finished a working prototype set of gears this afternoon. The gears in the video were fabricated from a single sheet of card stock and fastened to a folded card stock base with two brass fasteners. I fabricated the gears and base using a computerized 2D die-cut machine and basic software that is included with the machine. The intricacy of the gears almost necessitates computer-controlled precision versus the varying results of scissors.

Total Materials: Two sheets of card stock (gears and base) and two brass fasteners

Questions:

  1. Do the gears spin in the same direction? Kind of obvious.
  2. How many different ratio relationships can you identify? Not so obvious. You need to think about more than the gears’ teeth.
  3. The blades on a wind turbine produce energy that is converted to electricity through a generator. Would you attach the blades to gear A or gear B? Not obvious without the context of wind turbines. You probably need some additional information. Nevertheless, logic will likely lead you to a reasonable guess.
  4. If it took me 12 seconds to spin gear A in the video, gear A spins at what RPM?
  5. If it took me 12 seconds to spin gear A in the video, gear B spins at what RPM?

Drawdio: Measurement

Posted Jul 7 2011 by in Math with 0 Comments

My Drawdio kit just arrived via snail mail, and I am thinking that I will wait until tomorrow morning to begin playing with it. The kit, mind you, came with no instructions and a bunch of parts despite the claim that it was a working, tested unit. (Cough) Engineers (Cough). Luckily ladyada has a relatively helpful manual…

I am thinking that I might craft a couple of lessons about measurement that use a drawdio-equipped pencil. Measurement is a consistently problematic area of math for the teachers/students with whom I work. I am imagining a mixture of art, music, and math! Science would be the glue.
