anyone have plans or a reference for building a DIY conductivity probe? i'd like to use it to calculate salinity.

Hi, It seems like that Endraw from practical maker stopped working on that EC cuircuit because it wasn't stable and he wasn't able to get it to work.

I could prototype and test it but i don't have a conductivity probe...

Ive seen several concepts for ec/ppm boards. This is on my list for somewhere down the road, but far from the top of the list. I've found a good source for ec probes so I will grab one or two of those eventually.

What is your source for Ed probes? I was thinking about ordering the marine pinpoint probe from eBay for about 60 or to get the Ed kit from as

Where did you find that info? I didn't see anything on his page and he's selling the EC pcb there. Would be interested to know because I'm getting ready to start an I2C temp/ph/orp/ec board based on some of his circuits.
