Sorry that last reply was contradictory. 🙂 I *do* have access to PCB software. Either Eagle or KiCad should work.

[wilsonjholmes]

I do not currently, but I have used KiCad and Eagle in the past, I have access to both through my university.

I am comfortable with soldering and I would love to get my hands on stuff. Where could I get a look at the bill of materials and the schematics?

[wilsonjholmes]

When will the pH control add-on boards be available for purchase?

[wilsonjholmes]

Awesome! My university now has probes on hand and some of those atlas circuits on order. Will the code for this be on a separate branch initially in the GitHub repo? Eager to test and help.

[wilsonjholmes]

Yes. Atlas sells female bnc breakout boards that make it easy to connect bnc probes to the circuit with a breadboard.

One of the professors I am working with first suggested this one (https://www.hannainst.com/fc240b-small-diameter-foodcare-ph-electrode-with-stainless-steel-body.html) to me, but then got back with me later with another one (https://www.hannainst.com/hi1093b-ph-electrode-with-micro-bulb-and-extended-length.html)

[wilsonjholmes]

Was looking into this probe (a professor said that this one would work for their/our application):
https://www.hannainst.com/hi1093b-ph-electrode-with-micro-bulb-and-extended-length.html
I am not sure if I fully understand the different specifications of these probes outside of their pH range, physical size, and build materials.
Are there more things that I should be looking at?
I have been referencing this website to learn more about the probes as I have not worked with them before:

The probe she suggested uses a BNC connector so it should be able to be used with the Atlas EZO board (https://atlas-scientific.com/circuits/ezo-ph-circuit/) and a BNC connector. It is also only 3mm in diameter so it should be able to fit in the vial easily I think.

[wilsonjholmes]

…but then got back with me later with a different one (https://www.hannainst.com/hi1093b-ph-electrode-with-micro-bulb-and-extended-length.html) as the first one was meant for semisolids and would not be applicable to the research she is conducting.
