60 Really Cool And Creative Error 404 Pages

Having a good Error 404 page is perhaps as important as having great contents. Sometimes it may not be your fault visitors landed on error pages, but being able to communicate and direct them back to the home page is as good as a second chance to re-engage a visitor. Error 404 page helps you does that.

Black Moto Metal Wheels

Black Moto Metal Wheels:

Black Moto Metal Wheels - $700 (Lexington, NE)

Date: 
 tz2h5-3439432763@sale.craigslist.org[?]
I've got 16" black moto metals with 265/75/16 fierce mud terrains, the bolt-pattern is 6X5.5-$700obo

I've got the spacers and wheel adapters as well to mount the wheels to a Trailblazer-$100obo.

$700 for everything.

The only reason I'm thinking about selling is I don't offroad as much as I'd like, otherwise I love the setup. The tires have been rotated twice, and I'd guess the tread is at 90%*. The plastic center caps have some chrome chipping, that's it. If you're interested in all or part make me an offer. If for some reason you want these for a trailblazer you must have the spacers and wheel adapters or else these wheels/tires won't fit.

*NOTE: the pic of the tire is when they were new. They are NOT in that condition.

Plastidip Experiments

Plastidip Experiments

I was a little bored on Saturday so I thought I would mess around with the plastidip spray and practice a couple of techniques to see what worked and what doesn't. All plastidip test were applied to a painted/clearcoat substrate for the experiments(no, not on my car).

Masking:
Masked off a two inch wide stipe about 3 inches long
Four light coats of Plastidip applied and dried in-between each coat.

Test Pull #1: Straight pull of tape
Result: Ragged edge and looks like crap.
Test Pull #2 Cut line using razor blade prior to pulling tape
Result: Smooth edge, but a little wavy unless you use a straight edge. Also
will/can cut into the piece being plastidip.

Masked off a two inch wide stipe about 3 inches long
One medium coat of Plastidip applied and not dried

Test Pull #1 Straight pull of tape (while still wet)
Result: Nice clean stripe line

Finish:
Plain plastidip(four coats)
Result: Slight texture with a flat finish (looks fine because the texture looks
good with a flat finish)

Plastidip with clear enamel (Four plastidip and one clear enamel)
Result: Slight texture with a gloss finish. (looks like a paint job gone bad)

Removability:
Test #1 Four light coats of plastidip, dried
Result: Easy to pull off in large pieces.

Test #2 Two light coats of plastidip, dried
Result: Much harder to pull of in sheets. Worked best by rolling the thumb over
the edge like you would for removing double sided molding tape.

Test #3 Four light coats of plastidip and one clear coat, dried.
Result: Made the plastidip brittle and would not come off in sheets.

Obviously, there are several other combinations to explore, but I wasn't that bored.

Glitter or powered reflective material?

Tinting plasti-dip [Archive] - DipYourCar.com Plasti Dip® Community Forum: "

I normally would recommend watching Maynard G the Mix Master on YouTube but I can't get through more than about a minute of his antics and his ballpoint pens.

lol.

With the experimentation we've done, liquid tints don't work. We've gone through solvent based and enamel based. They make the dip too soft; it smears after it dries. Powdered colorants seem to be the way to go.. but not all work. Don't have enough data to point you guys in the right direction yet.. but working on it.

I have a bunch of extra crazy powder coat colors... would powdercoat make a suitable tint when mixed with plastidip?"

How to model a motorbike fairing using NURBS

How to model a motorbike fairing using NURBS

How to model a motorbike fairing using NURBS

Hi there,
this is a tutorial on how to model a fairly smooth and organic-looking fairing of a Suzuki GSX-1300 Hayabusa motorbike
We're going to be using both patch modeling ,more specifically,a technique called "lofting" (consisted of two or more
NURBS splines connected together with a flexible NURBS surface in between,hence the term "patch") and polygonal modeling,taking advantage of the many new modeling tools available recently in Blender (such as the Knife tool,Vertex slide tool and many more)
by the end of this tutorial we should know how to effectively model any smooth organic surface consisted of a single patch through using a variety of techniques


here's the link to this tutorial :
http://www.youtube.com/watch?v=K4BFucZameg&feature=plcp

NOTE : Please feel welcome to download these "blueprint"-looking reference images below and freely use them in your own modelling projects if you wish

hope you'll enjoy this!

Creating Geometries

The next step is to create a neat sphere object inside of our fluid domain. Therefore we change back to Object mode and press Shift + A. In the pop up menu we select Add → Mesh → Icosphere and set Subdivisions to 4 while leaving the radius at 1 BE (see Figure 4). The geometry is finished now and ready to be saved as a *.blend file
Figure 4: The new icosphere inside of the fluid domain. Note the additional "Sphere" entry in the Outliner window.

and on and on and then to:

Exporting to OpenFOAM®

The mesh is now finished and is ready for a final export to OpenFOAM® . From the menu bar we select Export → OpenFOAM® → OpenFOAM® (Grid only). We thereby create a case directory with the constant/polymesh folder, sadly marking the end of the main part of this tutorial.
enGrid also offers the export of complete case directories including solver settings. These have to be set up in the Solver tab of the Edit boundary conditions dialog. Afterwards we choose OpenFOAM® (Grid + solver parameters) from the export menu.

For Calculix, you can first model a surface in Blender and then import that surface into Calculix to be extruded. I posted the import script and brief tutorials in a few other threads. Blender is at www.blender.org .

Mesh generation for Wind Tunnel -- CFD Online Discussion Forums
I need to do this on the cheap as the Greenpower electric car racing is for secondary schools in the UK where pupils and the parents design, build and race electric cars. http://portal.beam.ltd.uk/greenpower...cer/index.html 

I was hoping I could create a mesh as follows: 
1. Create a simple car design using Pro/Designer CAD or Blender and export the design as an STL file. 
2. Use blockMesh to generate a basic wind tunnel mesh with inlet and outlet with an appropriate number of blocks. 
3. Use the cellSet utility to remove the cells from the wind tunnel inside the CAD STL surface. 
4. Use cellSet ? to create a named patch (wall ?) from internal STL surface. 
5. Use this resulting mesh with the turbFoam solver. 

I am new to this. Is this sort of approach likely to work (I only need basic results, accuracy is not required) ? 
If so any pointers on how to do this ? I have managed to generate the wind tunnel mesh and have removed the inside of the STL surface. The documentation for the mesh utilities seems very spartan ... I am unclear on: 

1. How to set the default mesh from the mesh and the cell sets created. I have used subsetMesh and then copied the "0.005" directory created over "0". Is there a correct way to do this ? 

2. How to create the named patch/walls for the internal STL surface. 

Cheers

OpenFOAM Motorbike Tutorial

    In Work - some information may be wrong! Also updating to OpenFOAM 2.1.1
    The basis of the Vespa CFD modelling (to start with at least) is the OpenFOAM Motorbike tutorial. Here are some notes on that tutorial, the first thing that people will need to do is get the tutorial to run before adapting it for a Vespa. Nerd Warning: This is a techy process to set-up and to get working, involving Linux commands and compiling and stuff. Also maths is involved and these notes are from a non-CFD expert and therefore are an overly simplified perspective (which may help or hinder). Any CFD experts out there, please feel free to jump in and correct and contribute!

    CFD | Computational Fluid Dynamics | Totalsim

    TotalSim are vendors of the Sculptor and 3-matic software products as well as offering a hardware solution in the form of a computer array. See sample specification below.

    Software

    Sculptor software from Optimal Solutions allows parametric shape deformations to be performed directly onto a CFD model. This vastly reduces the need for costly re-meshing and makes CFD a viable tool for design optimisation.
    3-matic software from Materialise enables rapid and accurate conversion from laser scan data to surfaces suitable for CFD or FEA analysis. The resulting time and cost savings make reverse engineering an affordable option for a far greater range of products.

    Hardware

    TotalSim has developed it’s own computer array that provides a compact, flexible basis for CFD solving. Click here to view a sample hardware specification.
