Choosing the right tripod stand can be a difficult decision, but if you want to avoid the hassle and save some money, making your own easy to use tripod can be the best way to go. If this tennis ball tripod isn't right for you, then maybe this disposable razors one by Instructables user Jawasan will do. This tripod stand only works for small cameras, so make sure yours is light enough before you start.
In this tutorial, we learn how to wear a scarf for fall and winter. First, take a scarf in any material and color that you would like for your outfit. Use a solid, lace, print, or anything else that you would like to use. After you have picked it out, you can tie it around your neck so one side is tied on the back and one is on the front. Or, you can leave both sides in the back and make it loose around the neck or tight. You can also spread the scarf out so it's a slight triangle in the fron...
This 3ds Max software tutorial covers how to turn your mesh into Hexagon poly’s which creates a smoother mesh. This is a technique Dave learned from Toru Hasegawa that he is sharing with all of us. You essentially triangulate a quad poly surface then collapse the triangles to have hexagons. Watch and learn how to convert a mesh into hexagon shaped polys with Classic Mesh Smooth in this 3ds Max modeling tutorial. Convert a mesh to hexagon polys in 3ds Max.

Last Thursday's post demonstrated how to Make Yin-Yang Pillow boxes, which were based on equilateral triangles and squares. The units for making these boxes were created by Phillip Chapman-Bell, who runs an amazing origami blog and has a spectacular flickr photostream. Using these units, you can make also make 4 of the 5 platonic solids. I made an additional template based on the regular pentagon so that the dodecahedron can be built completing the set.
After Cory Poole posted some great Escher snowflakes, and Cerek Tunca had the great idea of using it as a base for a tetrahedron, well, I just had to give it a go. I will post a few more pictures and variants later (I think this was what Cerek was envisaging—if not let me know!)
In Monday's post, we created a sliceform model of a hyperbolic paraboloid. In today's post, we will create a similar model using skewers. The hyperbolic paraboloid is a ruled surface, which means that you can create it using only straight lines even though it is curved. In fact, the hyperbolic paraboloid is doubly ruled and is one of only three curved surfaces than can be created using two distinct lines passing through each point. The others are the hyperboloid and the flat plane.
These are a few examples of my latest craze. It is basically a 3d weave of cocktail sticks—just lots of them. I have made them from chopsticks and skewers as well, but have given those as presents and don't have any pictures.
Modular origami is a technique that can be used to build some pretty interesting and impressive models of mathematical objects. In modular origami, you combine multiple units folded from single pieces of paper into more complicated forms. The Sonobe unit is a simple example unit from modular origami that is both easy to fold and compatible for constructing a large variety of models. Below are a few models that are easy to make using this unit.
+Tyler Neylon, a programmer and mathematician currently specializing in iOS app development, recently posted a fun project to his Google+ profile: 50 designs with 50 LEGO pieces, a set of 51 photos. Given a small 50-piece Lego set this past Christmas (well, Tyler admits: "...58 [pieces], actually, but many of them are very small, as you can see"), he craftily stretched his imagination to create 50 different models, though the kit included instructions for only 3.

If you haven't seen one, a comet is one of the most spectacular astronomical objects in the sky, partially because it is so close to Earth. At the closest, it is only 1.3 a.u. (194,477,400 kilometers) away from Earth. Comet C/2009 P1 Garradd was discovered by Gordon J. Garradd on August 13, 2009. It never comes closer to the sun than Mars's orbit. Usually, a comet moves fast, but it has stopped moving so fast recently, making it really easy to observe. It can be observed by a telescope or wit...

Knitting on double pointed needles (abbr: DPN or DP) is scary to most knitters. That being said, there will be times that you will want to, or need to use them, so you might as well learn now. You'll need to use DP needles for small projects when there are too few stitches for a circular needle (as for socks or mittens). Once you cast on and get into a rhythm, it's easy. Don't be afraid to try it.
