CarWorld is a small driving simulator/demo I use to test various things of interest. It was mostly developed when I was a student. It is released with the full source code under the GNU General Public License. The renderingThe two top pictures represent an slightly older version (v0.072) but graphically similar of CarWorld as it was presented for my project. v0.072 includes an OpenGL based renderer allowing

Open Source Robotic Arm
A five degrees of freedom robotic arm.
Why this isn’t quite ready for sale:
-We lack any inverse kinematics program which makes moving the arm intelligently nearly impossible.
-Without software limits on the servos it is capable of stripping the low cost hobby servo motors (this is alright for testing as they are only five dollars) (we have stripped two in the life of our arm and both happened when we were asking it to do silly things) (this can be fixed by upgrading the servos)
-We haven’t completed the 3d model or assembly instructions just yet, but by studying the photos it is possible to assemble. (think more jigsaw puzzle than lego set)
-The gripper, lets just say the gripper needs a little work.
That said it is an amazingly fun toy to play around with, and a good starting point if anyone has ever had a desire to make the perfect robotic arm (it is open source so you’d be free to make and sell your own)

The standard setup uses a Motorola 68HC908 microcontroller, the Windows operating system on the PC, and Matlab. An alternative setup was chosen, using a PIC18F4520 microcontroller, Fedora 8 Linux on the PC, and GNU Octave. This alternative setup allowed for an easier to implement software design, which outperformed other designs on a variety of levels.
Case Study: Fedora in an University Engineering Lab
Benjamin Kreuter and Robert Greene
May 14, 2008
Purpose
This case study provides details on how Fedora 8 Linux was used and relied on in an academic laboratory project. The motivation for choosing Fedora is outlined, and the advantages afforded by this
choice are discussed. In addition, the ability to use necessary proprietary software in Fedora 8 is discussed. Block diagrams of specific parts of the design are presented, to aid in illustrating how a
Linux system was used to accomplish the goals of the project. Due to concerns over possible plagiarism by future students, the specific results of the project have been omitted, but are available from the authors upon request.
Conclusion
By choosing a free software system, a superior software design was achieved, at no cost, in a university engineering laboratory setting. This design was more flexible than designs based on proprietary software, with a shorter development schedule. This project may serve as an example of how engineering students can use Fedora Linux in their education, especially in a demanding course in engineering design.
The four pages study is available clicking the title.
ORBITER is a free flight simulator that goes beyond the confines of Earth’s atmosphere. Launch the Space Shuttle from Kennedy Space Center to deploy a satellite, rendezvous with the International Space Station or take the futuristic Delta-glider for a tour through the solar system – the choice is yours.
But make no mistake – ORBITER is not a space shooter. The emphasis is firmly on realism, and the learning curve can be steep. Be prepared to invest some time and effort to brush up on your orbital mechanics background. Good starting points are JPL’s Basics of Space Flight, and R. Braeunig’s Rocket & Space Technology.
Acoustics is the science that studies sound, in particular its production, transmission, and effects. Sound is defined as a small mechanical disturbance that may propagate at a speed characteristic of the medium, provided the medium is of great extent compared to a typical size of the disturbance. Sound may exist in gases, liquids or solids.
The applications of acoustics can be broken down into four main categories: Earth Sciences, Engineering, Life Sciences, and the Arts. Engineering applications of acoustics include Noise Control, Electro-Acoustics, Sonic and Ultrasonic Engineering systems, non-destructive material testing, shock and vibrations of mechanical systems, and sound quality design of products. This book describes some of the fundamental principles of Acousticsand contains several practical examples.
