Hi Owl Face,

Hope Willy will contribute about your findings.

best regards,
Joe

At this point I wonder if this is the same code Willy and Jim use in the Mark series kits and I don't plan to build this mag any further. Anyone else attempted this? Is it possible I'm missing something? If I could get a corrected copy of the Main.C I'd like to continue building this project if anyone has done this.

Hi,

You're right. The signal processing in the Mark series is not the same as that one. This publication was aimed at showing the capabilities and speed of the LPC21xx series of processors to execute signal processing tasks. At that time, we were still at the very beginning of the long design and test work we've had to do to get to the now mature status of our project.
We have decided that the real signal processing code be kept as a trade secret, it is not on sales by itself. It has asked us too much work to let it go free or even being licenced in source code. It can only be bought as burned in our KIT. We sell the fully assembled and tested set of boards alone for a very attractive price compared to the usual pricing of equivalent commercial PPM's.
The current Mark series gives a resolution and sensitivity of 0.1nT on real polarization tests (reading rate of one reading per second) in good environmental noise conditions.
The signal processing has been designed to be much more noise and spike resilient than any period counting algorithms usually integrated in commercial PPM's.

Any chance someone could send me a set of these plans

Plans are not available but a kit is available here http://users.skynet.be/fa352591/index.htm

Willy, I am very interested in building a proton magnetometer to detect deposits of magnetite, please send me the information you can to build a model, or you can sell me the information and know that it will be useful to build my team, because buying one are very expensive in my country.
