Mr. Deselles has built several eddy current analyzers, custom software, and presented on this topic at a non-destructive conference in St. Louis.<br /><br /> NCPTT has been using eddy current technology in preservation and will be bringing this tool to the iPhone platform in 2010. <a href="http://ncptt.nps.gov/Podcasts/archive/Preservation-Technology-Episode-8-Eddy-Currents.mp3">Download
