There are many off the shelf range finding components available including ultrasonic, infrared, and even laser rangefinders. All of these devices work well, but in the field of aerial robotics, weight is a primary concern. It is desirable to get as much functionality out of each component that is added to an airframe. Miniature robotic rotorcraft for example can carry about 100g of payload. It is possible to perform machine vision tasks such as obstacle identification and avoidance though the use of a webcam (or mini wireless camera interfaced to a computer via USB adaptor). Link

Increase your download speed and resume broken downloads
FDM accelerates downloads by splitting files into sections and then downloading them simultaneously. As a result download speed increases up to 600%, or even more! FDM can also resume broken downloads so you needn`t start downloading from the beginning after casual interruption.

As an offline weblog client, BlogDesk lets you comfortably write and effortlessly publish new entries to your blog.
No need to use those annoying HTML Tags in the WYSIWYG editor. Images can be directly inserted and are automatically uploaded. Even publishing simultaneously to multiple blogs is a matter of a click. With the ImageWizard you can not only insert images to your posts – it’s possible to edit them as well (crop, resize, rotate, shadow etc., see Examples). Even Thumbnails can be created – the preview will be shown in the blog and a click on the image will open it in its original size (just like here in the right column). Linking and uploading those images is automatically done by BlogDesk

3D Scanning allows the creation of a 3D mesh from a real world object or environment. From here all sorts of application possibilities open up including; animation, archiving, medical research, rapid prototyping, industrial design and quality control inspection.
There are numerous options available to do this, each with their own advantages. Some read the object with red laser light, others use white light to record the subject, plus there are manual systems which allow point by point analysis of the object.

Hand
painted porcelains from Buran Benjarong are based on traditional Thai
style paintings. Religious Buddhist beliefs and traditions have been
deeply rooted in everyday life. The Buran Benjarong handmade porcelains
use intricate designs on gorgeous porcelain bowls vases, etc. The
production of the basic porcelain wares are by itself a very tedious
and time consuming process. The hand painting done on these porcelain
wares is a really slow process.

A virtual keyboard is a feature of a computer program or a program in and of itself that acts as a virtual extension of a controller, often with fewer buttons than a keyboard would have. In the world of desktop PCs, the Windows XP program On-Screen Keyboard acts as a virtual keyboard that can be operated with a computer mouse. In stylus-operated personal data assistants it is common for the user to input text by tapping a virtual keyboard built into the operating system of the PDA.
These keyboards are often used as features of emulation software for systems that have fewer buttons than a computer keyboard would have. A GP2X port of Bochs, the computer system emulator utilizes a virtual keyboard, but the GP2X port itself is notorious for being slow

We can get the 3D printer guy to hang out with the 3D scanner fellow and we’ll be another step closer to replicators. Here’s a 3D laser scanner using a Quickcam Pro 4000 camera, s100 SMS controller card and LSG 35 geared motor

The SCAN Z do-it-yourself 3D scanner works on the same principle as most other 3D scanners, the difference being that it is much cheaper to setup, and the main components you may already have, or can be sourced very easily.
