This is a project to connect an Eddy Current Tester to a Linux-based computer (such as the NIC) and create Open Source software to Detect Corrosion in the fleet of light aircraft. We are calling this project CanDetect and there is a SourceForge project to hold this work in progress. Join our developer mailing list if you're interested in our progress.
The Nondestructive Testing Information Analysis Center (NTIAC) discussed the project in their December 2002 newsletter (PDF).
A short article entitled What do you have in your walls by Alex Perry has been published by Linux Journal in the October 2002 issue.
A paper entitled Linux for low cost eddy current detectors, Finds nails in your walls and cracks in your aircraft was presented by Alex Perry in the conference track of LinuxTag 2002 in Karlsruhe, Germany.
A paper entitled Near DC eddy current measurement of aluminum multilayers using MR sensors and commodity low cost computer technology was presented by Alex Perry on 19 March 2002 as paper [4704-23] at the NDE and Health Monitoring of Aerospace Materials and Civil Infrastructures conference by SPIE in San Diego. The work described in the paper uses this project.
The first public release of the CDROM image for the NIC has been uploaded. It successfully operated Dr Avrin's low-frequency-capable probe, succeeding in detecting cracks that are buried under thick aluminum sheets.
Alex was unable to give this five minute talk on CanDetect, as planned, in the Work-In-Progress section of the Technical Conference at the Annual Linux Showcase 2001 in Oakland. A different project was undergoing final testing for field trials.
The donated disk drive bracket for the NIC has arrived, which allows the diskless unit to be operated with a hard drive for development work. Unlike our existing LTSP-based network boot, this allows demonstrations at airport locations, with software development.
The unit from the ThinkNIC company arrived. This unit has the potential to offer a truly low cost NDE tool, as described over here.
