Sam's Oceanic 120 - DIY solutions

I may try a DIY Trident first but the DIY par meter is probably easier...

Baby steps.

Baby steps.

may not make it past the desk... still fun messing around with the stuff.

Parlameter? Eh?

My Hanna test kit gave me 165 ppm Alk.

The sensor lines from my thing for the same sample are below:
First two lines are just tank water, next two are after 1ml HI772S Alk reagent

R: 251 G: 488 B: 451     C: 1292  - Color Temp: 8236 K - Lux: 358
R: 250 G: 489 B: 452     C: 1293  - Color Temp: 8279 K - Lux: 359
R: 214 G: 409 B: 369     C: 1079  - Color Temp: 7960 K - Lux: 306
R: 215 G: 406 B: 366     C: 1074  - Color Temp: 7876 K - Lux: 303

not sure how to go from one to the other...

I think I need to add something reflective behind the vial so I get better reading.

glued white paper behind vial in the tube. new readings:

R: 1235 G: 1980 B: 1874     C: 5428  - Color Temp: 7172 K - Lux: 1352 
R: 1235 G: 1978 B: 1871     C: 5421  - Color Temp: 7163 K - Lux: 1351 
R: 331 G: 662 B: 468     C: 1575  - Color Temp: 6777 K - Lux: 594
R: 331 G: 655 B: 465     C: 1568  - Color Temp: 6743 K - Lux: 586

for completeness: - this is what Salifert does I think. Their indicator works on pH, not Alkalinity...

Now I know why I never get the same result twice with hanna:

using the one-point titration method, an average alkalinity of 2134 ± 2.7 μmol kg−1 was obtained for an in-house seawater standard (Table 2). In contrast, using the same in-house seawater standard and approach, but with the purified dye, we obtained a value of 2138 ± 1.2 μmol kg−1 (n = 10) (Table 2; Fig. 3A). Consequently, there appears to be a small offset in the “true” value obtained using the impure dye and a decrease in the precision of the method.

the process to purify the reagents is pretty crazy. off the shelf may be the way to go...

I'm mainly just wondering if I can apply the new RMM Magnesium testing method to all of my different levels :thinking-face:

I like the idea of a parla meter

I'm still considering redoing my lid here soon. Acrylic and screen.

Still love the cable management you printed for the steel stand. Amazing .... Still have tweaking to do. But it's so nice

Sam love your designs and tec you biuld but when I see a chip board it all goes over my head. But great watching you invent stuff.

I hope I can get my big cnc built in-time to help you with that!

Part came in so I could continue:...
Best one I've found thus-far:
https://www.electroniclinic.com/ph-...r-calibration-diymore-ph-sensor-arduino-code/

Got it to the point where I'm dropping it into my stand.
Just need to get a power supply.... I may just integrate it into my Kalkwasser stirrer.
It'll increase the price but I think its a real value add.

Just printing up the new case...

Very cool. I was looking at getting a Milwaukee ph controller that I can hook up to a ball valve to control the recirculating scrubber I am setting up.

I setup this on 12 power adapter plugfged into my EB8. used my Apex PH tp cpntrol it.:
https://a.co/d/6JBZ1jubut dismantled it when my ph never got over 8.4

No apex here.
