Fab it Yourself

3D printers and other types of rapid prototyping machines are the latest innovation in manufacturing where components are built by depositing material (usually plastic) layer by layer. Until recently the cheapest machines were still expensive (in the $10,000s range). Not anymore – now there are freely available plans for fabricators (fabs or fabbers as they are known) that are well within the price range and capabilities (assembly required) of hobbyists.

Texture Mapping

Texture mapping is a simple technique to make a 3D model more realistic. It is also a great way to brand either a 3D model or an image with a logo. It is even useful for arranging multiple images within a 3D composite image.

Simulation for Illustration

Sometimes an accurate simulation of a realistic scenario such as the aerodynamics of a racecar, is too much. Sometimes all that is needed is a simulation that highlights a simple concept or idea – welcome to simulation for illustration.

Paper Airplanes

The Chinese are attributed with the invention in AD 105 of what we know today as paper. A good bet is that the first flying paper object soon followed as a screwed up paper ball flew toward a trash can. Recognizable paper airplanes appeared much later, with sightings coinciding with the first powered flight by the Wright brothers at the beginning of the 20th Century.

Flying Wind Turbines and Blog Action Day

Today (October 15, 2007) is Blog Action Day and upwards of 15,000 bloggers will cover subjects related to the environment. The aim is to raise awareness of environmental issues – this post is my contribution to the cause. Environmentally friendly, renewable energy generation is a theme I've covered in a number of previous posts ranging from wave energy to horizontal, vertical and micro wind turbines. Continuing this theme today I'm going to cover flying wind turbines.

Faceted Modeling

A vast army of 3D artists, initially led by movie and game animators, but more recently joined by students and hobbyists, have compiled an extensive archive of 3D faceted models. These models cover every imaginable item from the mundane, such as eating utensils, to the realms of pure fantasy, such as the Starship Enterprise from Star Trek.

Submersible Racecar

While on the surface it seems that submersibles and racecars share nothing in common – dive a little deeper and you'll see that they do. Racecar giants Lola and Cosworth are playing a major role in helping BAE Systems develop an Unmanned Underwater Vehicle known as Talisman.

Micro Air Vehicles

Micro Air Vehicles (MAVs) are a relatively new class of flying craft that are attracting interest from a broad spectrum of users spanning soldiers to children.

Microfluidics

Microfluidic devices played a leading role in the sequencing of human DNA during the Human Genome Project, resulting in its completion ahead of initial estimates. They can also be found in most inkjet printers controlling the ink sprayed onto a page. Further advances in the design and manufacture of microfluidic devices, such as the so called lab-on-a-chip, show promise for a revolutionary range of applications.

Air Blowing Applications

When the naturally induced airflow over a moving aerodynamic device, such as a wing, just isn't enough to satisfy design requirements then strategic air or gas blowing is always an option to enhance the device's performance.
