I'm familiar with this issue--it gets even more expensive when an airplane is envolved. I'm an officer in a Chicago-area flying club--we do our own oil changes and other maintenace that pilots are allowed to do, as opposed to FAA-certified mechanics/technicians.
The problen is that the white tail position light (running light) is mounted on the rudder--the moving part not the stational tail fin. With age and lots of flexing (it is a major control surface!) the wire breaks. Pilots are allow to change the light bulb but not trouble shoot and repair the wiring. We trouble shoot, but a certified technician is required to solder the wire, and now you have a hard splice, just like the car stereo. It's about a half-hour job, and we have one or two Airframe & Powerplant licensed mechanics in the club so it was easy to make the airplane legal at night.
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
