OhmPi low-cost, open hardware resistivity meter

[pheomis]

I have minor issues with parts. Plugs, cables, and final assembly. This takes a lot of time. I slightly modified the power supply. It's not ready yet. Regarding the configuration, I spoke with GPT CHAT, and he promised to help me configure it. The initial conversation showed that he understood the issue and seemed to be able to do it.

j570 Thank you, I couldn't figure out how to make the probes. Everyone is working with very thick and large cables. I don't know if I should buy a ready-made cable and try it or if I need something else. What's your plan? I have a small field and I'm thinking of finding water using this method.

I have several rolls of 4x0.75 mm² shielded cable, 25 meters long. I plan to use them to connect the probes. The probes are made of stainless steel rod, 8 mm in diameter, 35 cm long.

Thank you so much j570, Are you going to conduct a water density study too? I think you're considering doing this for a non-water search. I'm guessing you're doing this because your cable cross-section is too high or too low.

I'm thinking about doing some archaeological research. I'm using the cable I have and it seems to be fine. I'm not sure if the probe diameter is too small. But I got 32 pieces for free.

Has anyone managed to complete it and could provide a photo and sample ranges and a description of how it works, whether it works well or not?

[j570]

I still wait for some parts like Mikroe 4976.
