More Modular Madness

000_8593.jpg 

This modular is an amazing frisbee and while I don’t necessarily advocate “throwing money around” in this case I say make an exception.  Quite thick at the edges, but it is a sturdy octagon.

Very crude instructions here http://www.flickr.com/photos/christine42/2327491169/in/photostream/

Pentagonal Star-Really Pentagonalish.  Although it lies flat the fit is not perfect.  Not a unique style connection, but I like pentagons.

Varients on previously diagrammed model.  Hexagon in Embedded Star and Embedded star.  The first is a forced fold, not natural and does not lie flat.  The second is the flat variation.

Same disclaimer/request if you have seen these please post applicable designers and links.  Thanks:)

2-D Modular Design Process and Diagrams

Lately I’ve been playing with dollar bills and that translated into modulars which can be seen two posts down.  As of yesterday that translated into 2d modulars with a square.  I am the first to state there are tons of modulars out there and my designs are probably not very unique.  When I started doing origami I generally focused on 3d modulars, but I have taught three particular 2d modulars (One is called the “Magic Frisbee,” another is a Mette Pederson unit, and the final one is a stellated star that I learned from a origami day planner with a frog on the cover).  However this post is only about “steps” I have observed when I am designing modulars with dollar bills or squares.

 2-D Modular Design Process

  •  You have to have something that is either a pocket or an edge to but the next piece next to.
  • Determine if you can make it work around a single point.  The angles must come to approximately 360 degrees.  You can do this with math or (like I tend to do) just make the modules and assemble.
  • Determine the two angles the modules can shift in.  Depending on the angle of the pocket/edge from step one the angles are different.
  • Determine a way to keep the shifting from occuring by tucking somepiece into another piece.

I admit these are obvious steps, but once I verbalized them when trying to explain to my mother how I came up with things it has been easier to make things come together.

Edit:

Here are some dollar bill modulars.

After making a series of dollar bill modulars I applied the same approach to a square.  The results are two units I now I havn’t made.  However the end design of the three step module I have seen.  My standard request applies…If you have seen them please leave applicable designers and links so others can find them and we can all expand our knowledge.  I asked around at the CHAOS meeting today and no one recognized the modules, although Robert did say the end result was familiar on the three step modular. 

 

In the last step (which is what makes the modular fairly strong)  I bisected the paper from the tip, allowedthe bottom by the white edge to go down, and tucked the excess into the white Isosceles triangle.  If you want it to look like the pink design repeat on the other side.

Hexagonal Dollar Bill Modular Instructions

You will need 6 crisp dollar bills (or larger if you so wish) and a few fingers.

  1.  Fold dollar bill in half lengthwise.  I recommend keeping the same orientation I have the first time you make it.    
  2. On the one side quarter it.
  3. Fold in half, Valley fold, as shown in photo.
  4. Take the lower left vertex and bring it over to the quarter crease line.  The other point it references is the center crease line.  
  5. Inside reverse as shown.
  6. Use the upper left vertex and bring it down to the center crease mark making a crease the the other top vertex. Unfold
  7. Repeat on the left side and unfold.
  8. You are folding down as if to make a waterbomb base.
  9. Flip unit over and repeat.  When done reverse all creases so the “waterbomb” is in the inside.  Make 5 more units.  
  10. Put units together as shown.  You are putting the one on the right into the one on the left.
  11. Between the units where the units connect fold a bit of paper over.  This creates a strong final product.                    
  12. Assemble all 6 units.  Should look like the picture.  Then flip over for the next step.
  13. You are tucking in the left angled flap all the way around.  It goes around the other papers in the inside.  Now this side has only rotational symmetry not bilateral symmetry.
  14. Flip over.  Now you will be collapsing the modified waterbombs.  Be sure to include the tip from the other side that was left out.
  15. Now you are tucking in the tips that are sticking out so that everything is contained.  The final modular should be internally very strong.                                     

Moneyfolds: My design approach

Just a few thoughts on the process I’ve been using for moneyfolds lately.  Dollar Bill origami is a very recent foray of mine.  I have found the dimensions interesting from a design perspective.

My basic approaches:

  •  Not to be flippant, but I fold.  I take every angle and bisect, trisect, and intersect it in every way that I can think of. 
  • I try to collapse things in different ways from all different angles and sides.
  • Visualize what I want and deconstruct the folds in my mind(only works on rare occasions and never for highly complex stuff for me)
  • Once something bares a resemblence keep refining it till it is good enough.
  • Make more than one of something and see if they’ll hold together.

I have had mixed results with these approaches and I havn’t done much with animals (certainly none worth posting) but I do find it interesting to play with something that has limited symmetries.

Side bar… I have now had this sight for a full year.  Time flies when you are folding.

Dress Diagrams & Dollar Devil

The initial steps of this are a pain.  Reference points carefully. 

1.  Fold in half lengthwise.db1

2. Mountain fold as indicated.  The second pic shows the reference points on the dollar bill.

000_8440.jpg000_8441

3.  Look at pic.  Line up the right side and make mirror folds.  Do it on the other side.

000_8442000_8445

4.  You are making a valley fold that is the diameter of the circle.  Use reference points for alignment.  I’ve also drawn the line for reference. 

000_8443

5.  This is sort of similar to creating a waterbomb base.  The trick is some of the paper in the center overlaps and has to goto one side or another.  I highly recommend referencing the pictures for this step.

000_8449000_8450

6.  Flip over. and valley fold betwee the two vertices.  The crease line is drawn on the bill.

000_8453000_8454

7.  Flip over.  You are folding the vertical lengths to the center crease (folding quarters).  It should start resembling a dress/robe.

000_8459000_8460

8. The tips that are sticking out above the shoulders are mountain folded to match the edge behind it.

000_8461000_8462

9.  The arms are mountain folded on the line that between the white and green on the bill.

000_8463

10.  This section is to taste.  I mountain fold the bill and then valley fold.  Reference pictures.

000_8466000_8467

11.  Flip over.

12.  This makes the waist.  I recommend looking at the photos and trying to repeat.

000_8469000_8471

13.  Flip over.  The tips by the hips need to be mountain folded to soften them.

000_8472000_8473

14.  If you want you can end here. 

15.  To add detail fold back the edges of the dress.  See pic.

000_8474

16.  To shorten dress  pleat internally to taste.  You can fold the tips at a 45 degree angle for more detail.

Dollar Bill Butterfly Ring

Same old spiel…creative commons, if you’ve seen it before drop a line and I’ll put information and links in…

000_8105.jpg

 Butterfly is big-this is origami bling and would engulf a childs hand, granted my fingers are stubby little nubs, but that said tis a large butterfly not a diminuitive winged ring thing.

 1.  Fold bill in half lengthwise.

2.  Bisect right angles and unfold as indicated in pictures two and three.

000_8120.jpg000_8123.jpg000_8122.jpg

3. I flipped the dollar over and then created two vertical creases using the point of intersection from the two previous creases.  Undo and then flip and make two waterbomb bases on each end.

000_8124.jpg000_8129.jpg

4.  Fold the bottom up approximately 1/3 vertically and then fold the top down.

000_8130.jpg000_8131.jpg

5.  Flip over the “arrow” and then you are valley folding a vertical crease.  I line it up with the curve, allowing that to represent the body.  The bigger the tip you fold over the smaller the ring.

000_8136.jpg

6.  Open sink the tip.

 000_8138.jpg

7.  Wrap the bill around(refer to picture) and you are  going to put the tip into the open sunk tip.  If you can make it match up as you slide it in it will be stronger.

000_8139.jpg000_8140.jpg

8.  To form wings I pinch a little paper horizontally and fold down.  I then fold the little tip where they meet inside (this is a common fold in butterfly wings I think)

000_8142.jpg000_8144.jpg

9.  Flip the bottom of the wing tips.

Dollar Bill Flower Module Diagrams

These are pictoral instructions.  They are not 100%, but they are what I’ve cobbled together for the moment.  You will need three or four dollars.  I don’t recommend hell or heaven money as they don’t hold all that well.

 1:  Fold the bill in half lengthwise and fold the corners down as indicated in the picture.

dollar-one.jpg

2:  You will unfold the corner tips and use them as a reference line to fold the edge to.  Refer to picture.

dollar-two.jpg

3:  Fold the edge back down and repeat on the other side. Refer to second picture (the dollar bill bustier:))

dollar-three.jpgdollar-four.jpg

 5:  Fold down the back triangles to match the front.

dollar-five.jpg

6:  Fold in half. 

dollar-six.jpg

7:  Mountain fold along the existing paper edge.  The pic on the right is what the unit looks like when you’ve opened the petal up.

 dollar-seven.jpgdollar-eight.jpg

8: You will need three or four completed units.

 dollar-nine.jpg

9:  You slide the tab into the pocket and keep doing that all the way around.

dollar-ten.jpg

10:  Put finger in each petal and open it up.  The more dollars the thinner the petal is.  The picture below is with four units.

Dollar Bills Strike Again-The dollar bill modular flower and other tess stuff

Well after the years of modulars I can’t determine if something is new or old.  This seems excesively familiar although an hour long internet search yielded nothing, although I didn’t check standard Kusadama’s.  So I will diagram it after I check with a few people, because diagraming stuff that’s on the web seems redundant.  The one has three 20’s the other 4 really grungy singles.

000_7919.jpg000_7920.jpg000_7924.jpg

Playing with small tests while I am trying to grid some large pieces.  I started something called “Spinal Reconstruction” for my chiropractor just after Vancouver and I still haven’t finished gridding the pieces.  My most recent small test is below.000_7935.jpg
