TV Interview: Curtis invents Eddy Current Analyzer with ViewPort + Propeller

Curtis has developed a tool that helps archaeologists and detectives to read impressions made into metals like coins or guns even when they’ve been sanded of.

Here is his interview with a local tv station.

Here some more details:
I got a great deal of help from the forum members and I feel the project should be in the public domain. I enjoy learning about electronics and love Parallax products. My field of expertise is Archaeology, but I love Physics also. My final eddy current analyzer probe included a hall effect sensor. I will be showing this technology to law enforcement and other government agencies and will be offering my services free of charge in the near future. I will insure that I plug Parallax and ViewPort as well. I ordered and got a surface mount version of all the supplies needed to build my instrument in a smaller footprint.
