Archaeology Resistivity Meter

kltm

Hi I'm looking for ideas on an update to a resistivity meter for archaeology. The only published designs for diy were in 2 magazines. One was published in 1997 and the other in 2003. I have copies of both articles available. The reason behind this is the current high cost of available equipment, usually well beyond the reach of most archaeological groups. I've attached a basic block diagram. In the first magazine article the meter is very basic. It relied on the operators to write down the reading given as the survey was taken. Given that a normal survey grid is 20m x 20m and 1 reading is taken on every sq mtr there would be 400 readings to write down and then input into a program used to interpret the results. The later article is really an update to the first where a PIC has been added to record the readings. This again is prone to error, because eadings are taken manually by pressing a button.

I'm sure given the advances in electronics there must be better ways.

  • Hi Ken,

     

    For the block diagram you inserted in an earlier comment, if you don't mind, it may be good to create a new document (i.e. click the orange 'Create' button at the top-right, and then select 'Document') in the Open Source Hardware space, with the block diagram inserted in there as a visible picture, so it's quick to refer to. I've done that with the high-level solution diagram, here: High Level Solution Diagram for Archaeology Resistivity Meter Project

     

    Also, this discussion, plus the new document, can both be tagged something unique and easy-to-remember, and then I'll tag my diagram identically, so they can all be found with a single tag as a search term, because it's a struggle to find the diagrams output within the comments here, due to number of comments.
