So I have been, comparatively, out of commision to a large extent the last two years. Work and getting a graduate degree took precedence over life, liberty, pursuit of happiness, and all that jazz. Here is what I did in the last week and two modular instructions for units I did (sometime in the last several years, probably more recently, but memory is a fallible, short-term, gnat like thing for me) no guarantees they are not redundant.
Standard disclaimer: The simpler the unit the more likely it’s been done before, please post information and links if you’ve seen it, done it, or something very similar. Creative commons applies to all and have a happy new year.
1. Fold in half. 2. flip over and fold bottom edge to center, same on top. 3. What it should look like.
4. Fold quarter fold to center repeat on top 5. Vertical view. 6. Side view.
7, 8. Fold bottom edge to right edge and then bottom edge to left edge. 9. Collapse to a waterbomb. Repeat on other side.
10. Fold in half to the smooth sides of the two waterbombs meet. Refer to picture 11. that is the final unit
I recommend the 12 or 30 unit first as they are easier to assemble. Refer to picks for connections at each vertex. The twelve unit is functionally a cube and the 30 unit a dodecahedron.
Happy holidays from sock monkey.
So I have ended up on a tangent that I would eventually like to use for posting tutorials for my students and have lectures students can view if absent. So I decided to try to create an origami tutorial. I may have done this design before I sadly don’t remember. Editing is a challenging business, as is seeing yourself (in all your redundant glory) on camera. So for those who do post tutorials online kudos, it’s a lot harder than it looks. I will within the next week post about Italy, but this comes first since it’s done. Bear with me as it is my first attempt at video instruction and it is not polished all pretty, plus I am using the camera in my mac which doesn’t allow for as much flexibility in filming. Youtube said it’s processing so here you go, remember creative commons applies to all unless stated otherwise. Happy holidays.
Below is an corrugated automata that doesn’t inch the way I originally plan, but sometimes the best laid plans fail.
For people who have sent requests for things I apologize as I spent the better part of the last three weeks away from home and if it is for computer based candy container diagrams my other computer is not functioning right now. I will send stuff when I have the computer up and running.
As usual if anyone has seen this modular please post information and links as applicable. The unit was designed to create the same effect (although with a completely seperate unit) that another 3d wreath has. The units are not remotely similar, and sadly my unit does not have the flexibility or strength that the other one has. The modular can be done in 8 or 20 depending on the variation, of which there are many. The instructions are for the 20 unit variation. As for the oddly bolded sections that is something the blog is doing and I can’t fix-since wordpress is free I can’t complain.
2. Fold as indicated and crease and then undo.
3. Fold the bottom right edge to crease line
4. Fold tips around edge and tuck them inside.
5. Take top point and fold to bottom point and crease.
6. Take the two flaps folded in the last step and fold inside the pocket. You will have to reverse the direction of the crease on the front fold.
7. Put the unit sideways and fold the tip so it is roughly parallel with the vertex of the obtuse angle. Do it one and then rotate the unit and do it the other way.
8. Finished unit, make twenty total
9. Tuck in as indicated. Make sure that you are tucked in on both sides.
10. Keep adding units until you have the original photo.
Some fun sites.
So I was in Wisconsin, at Lake Harris. I think winter is the time that we are gifted with seeing a tree’s architecture. The pristine lines don’t err and aim towards the heavens against a backdrop of Robin’s egg blue. The stark Birches and lily white snow were beautiful if bitterly cold. So amidst the joy of grading papers I folded.
Oceania Box-Older box, but one that I still like. I don’t think I’ve posted it here before.
Partial Diagram: After step 6 just make a standard masu box. The edge reference for the edge of the box is the first pleat from the edge. Make two. Then pull apart the sections carefully, fanning them out. Make two.
In Wisconsin I played around with 2d modulars again. Before I post instructions I would like to know if they are already floating out there in the origami ether. If you recognize them please state who and a link if possible. I checked out a site moduladia? and a site by a gentleman whose website escapes me at the moment. So if the designs and or modules look familiar I do appreciate information before I bother trying to diagram.
Last thing from the cold northwoods is a tessellation. Was originally going to do a mask , but sadly that, as usual, was pushed to the side. So here it is backlit.
Hope you all have a safe and happy new year.
Stellated 12-gon. If you skip step 5 or vary the distance of the fold you change the number of modules needed. Given an n-gon the smaller the fold to the center the larger n (i.e. the number of bills) is.
Had to redo the diagrams as the originals went to the Land of the Lost. The second group of photos is work on combining boxpleating and goran pleating with deconstruction. This is most recent in a series. If interested more shots are on flickr. http://flickr.com/photos/christine42/ I also tested some flax with this pleating to see how it held up. If I can get large enough sheets I will probably also do some more with flax.
Oh St. Patty’s day is near!!! For many (I am only speaking of Chicago, cause that’s what I know) it is special day celebrated in any place that serves alcohol, by the Green Chicago River, or at the parade. In honor of such a green holiday I am posting triangular pyramid tip box instructions and a Celtic cross modular (In deference to it being the holiday of a saint and all.) The tip box is made from a bill and closes. You can fit the coins that go with the tip in it. Remember your server is harried and tip generously. The box was inspired by this box from Lorenzo Marchi. http://flickr.com/photos/lorenzomarchi/227362566/
The modular is of an almost identical unit that an Italian folder, Franco Pavarin, published, with one difference. I wrap a section around another section that forces a color change and it does change assembly methodology a bit. Thanks to Mark Kennedy for helping me get the information to clear that up. I like my unit better because it is stronger during assembly for at least the one completed modular. I made two with his and as I found the assembly to be harder. Soon I will post the 15 assembly varients I made.
Tip Box Instructions
1. Fold the creases as shown. Make the crease bidirectional i.e. fold in in both directions.
2. The vertices of the two squares are pulled down to meet each other. This action cause the basic two triangular pyramids to form.
3. In the triangle that is in the middle you are pushing up the triangle tip. You are using pre-existing creases.
4. Inside I pink the edges of the pyramid and flatten them clockwise. The second picture is what the bottom looks like.
5. You are flipping up the rim of the top of the container all the way around.
6. The bit of bill connecting the top and the bottom needs to be creased so the top can fit in the bottom.
7. The extra flap needs to be folded so it is the same size as the rim. I folded it in on pre-existing creases.
8. The tips are folded in so that the flap can hold the lid closed.
9. Congratulations close the box…you are done.
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:)
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.
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.
