There are options for inexpensive spectrophotometry these days. Computers and cell phones have a lot of spare processing power. LEDs provide inexpensive stable light sources.

AHHHHHHHHHHHH WHAT HAVE YOU DONE TO ME!!!!!!!!!!!

Now, I have to quick ring Santa and ask for this. Forty mere clams, whutta value for geekdom. Hmmmm, come to think of it, I don't have to run to find my cell, since they don't ship until Feb. Perfect timing. You GOTTA love their spectrophotometer housing, that so suspiciously looks like this. Hm.

Need to figure out if these little lovelies are quantitative as well as qualitative, because we needs quantitative for the LaMotte readings (and other tests). We need to know more than what the wavelength is. We have to be able to compare how many photons at a given wavelength. I have to finish reading how these babies work.

Wow, this is gonna be fun.

Shrimptern 2.0 are you reading this??? You may have to come back here so we can make this thing and run calibrations. Wouldn't that be fun? Or mebbe some geeky Shrimptern 3.0 would like to come work on this project a week, over spring break (hint hint)...

Thanks a ton, Don!!

Um. Where's the $25 GC-MS DIY kit link?

Calibration is going to be the key. The open source database will help a lot and becomes more useful and valuable as people build their own devices and contribute to it.

Here is another link someone with your interests probably shouldn't spend too much time browsing.

DK should like to have THESE, lining the walls of the Shrimporium. It would really freak out any new Shrimpterns, as they walked around in there. They look to be activated by a motion sensor. DK would rig the sensor to also start an audio of shrieking and screaming. Or perhaps moaning. In another corner of the Shrimporium, she would extend this idea to have a motion sensor activate a disco ball, some flapping origamis, and a loud audio of Queen of The Wave. Heh heh heh...

**********

Difficult as it is, DK is now returning to the project AT HAND, putting ASIDE these neato future obsessions, at least for one post.

Crystal, back to you. Back to the orange bubbly stuff, in the picture.

Thinking back on our carbonated bubbly soda, giving off CO2 soda fog as it hits the ice cubes. (bing bing bing: ice cubes = matrix)

Sorta like making butter. Ever made butter? Most people haven't. You start with whole milk (not the homogenized sort, the from-the-cow sort) which is a soup mixed of milk aqueous solution and emulsified with milk fats. Yeah.

You pour this complex mixture into a chamber, and... basically you agitate this mixture around, until butter forms.

But what is happening, when butter forms?

Why, of course, it's the holiday cocktail party.

You throw a buncha people in a room, and after a few hours of hors d'oeuvres and cocktails and (this is the agitation part: ) mingling, the drunks are grouped together at the bar (bar: think of the bar as MATRIX), thinking themselves clever, sucking down liquid courage. The sobers remain dispersed throughout the room, trying to get away from the bawdy too-loud stories coming from the drunks at the bar. The execs are trying to act above the fray, but we know where they really belong...

And there is WAAAAAAY too much colorful, glittery fashion that shows WAAAAAAY too much skin on bodies that shouldn't be showing that skin...

Like this (i.e., the drunks), fat particles begin to stick together and clump, when sloshing whole milk around in a butter churn. The clumps snowball in size, and you get a lump o'butter in the end. If you do it right.

Gas molecules in solution are kinda like this. They look for an excuse to come out of solution, but sorta need a place to stick and gather friends, to make bubbles, before then can then rise as a bubble and escape solution. (I know, I know the REAL scientists reading this are groaning at DK's florid analogies that are not QUITE perfect.) Ever notice how in a tumbler of soda, or a pasta pot of boiling water, the bubbles start on the surface of something, generally? The sides of the glass, or the bottom of the pan?

This is because the gas does better coming out of solution if there is a matrix surface to stick to, to start the snowballing process.

So, enter DK's CJDS matrix, the orange stuff.

This picture is from a jar of DK's tap water with the matrix down in the jar, allowed to sit overnight. You can see how the bubbles of CO2 wanting to exit the liquid have formed and grown on the matrix surface.

So, back to our conceptual equation:

The rough conceptual equation for degassing is:
RESIDENCE TIME x degassing rate x increase in temperature
= amount of degassing that occurs.


Part of the degassing rate is whether you provide extensive matrix surface, to initiate bubble formation faster and help grow bubbles. The greater the surface area of matrix, the more efficient bubble formation. The other two considerations of rate are agitation and solution temperature.

Even without heat or agitation, the presence of matrix will help you to degas a solution.

But for now, ponder on this picture, and think MATRIX.


Ooooooo. DK just thought of a neat experiment to try, to illustrate a point coming up. She needs two cashew jars, some matrix, some of her well water, and a fridge. Fortunately, she eats a lot of cashews, every day.

WE INTERRUPT the DK's CJDS posts to bring you this:

LEDs arrived today. Surgery on the piano lamp, tonight. I was gonna take before pics, but Other Geek was burning to rip the lamp apart, so I did not have the opportunity.

It turned out very well. We did a few other mods to the lamp while we had it apart, for maximum adjustability.

And we have the lamp plugged into a Harbor Freight foot switch, down by the piano pedals.

OK, carry on.

DK looks around furtively, for other places where she can convert to LEDs...

WE INTERRUPT our DK's CJDS posts AGAIN, to announce that DK's been rather bad, shopping and buying items for a Christmas stocking for herself, that might involve different sorts of crees. (She draws you aside to whisper conspiratorially into your ear the following: half the fun of m..a..d.. d..o..i..n..g..s.. is politely called "beta testing," which really means try a buncha stuff based on squirrely brain ponderings and see what happens, and if there is a catastophe, try to figure it out and solve it. The thing is, she loves to mess around with ideas, and products, and see what comes of her cray-zee "thoughts.") Yesterday, she spent we-won't-admit-how-many hours doing research, and the magical runes seem to indicate xpe and e27 and 6500. Yeah, that's it. Stay tuned.

That's all I'm gonna say. Santa might be late, as most are coming from overseas.

Oh, wait, she also has on good authority that Santa might be leaving her a new batch of gamma seals under the tree. (Honestly, you can never have too many gamma seals. They are just so useful.) This is the time of year when she gets antsy and all of a sudden the squirrely brain explodes in project mode and she gets raw materials needed that aren't in the bins & barrels. OK, so maybe she doesn't always FINISH the projects in the dead of winter, but the brain sure is busy scheming. She has YET to install the DK Water Snake. Yeah, um, and finish making all the Maseratis.

Hey, anyone out there wanna be Shrimptern 3.0? The projects are stacking up, and DK has accumulated hunger from when she had pneumonia and didn't eat well. Must be housebroken.

The Shrimporium is not unlike an advanced game of Whack-A-Mole. The moles would be: equipment issues, power issues, water chemistry issues, fauna and flora husbandry issues, maintenance issues, streamlining issues, emergency planning issues, etc. Oh, yeah, and this mole: recordkeeping issues - HEY I NEED A SHRIMPTERN 3.0 WHO CAN HELP ME WITH THIS PROJECT ALONG WITH OTHER COO-EL PROJECTS LIKE THE DIY SPECTROPHOTOMETER AND THE DK WATER SNAKE - CAN BE THIS SUMMER OR THIS SPRING BREAK IF YOU ARE A STUDENT TYPE. WE FEED AND HOUSE YOU WELL BUT WORK YOU HARD DOING CRAY-ZEE WEIRD SHRIMPORIUM DOINGS.

Right now, DK is grappling with an unusually high failure rate of a heater she started to transition over to. Thankfully, she didn't fully transition (she buys heaters as she has shrimp cash).

Here is the product. DK's experience is that this product has a much too high failure rate. About half of the units she's installed have already failed. So, she warns you. The picture below is the type DK actually has, the newer model is in the link below.

Via Aqua titanium heater. She has an older styling than this picture, and they may have fixed the problem, but her problems are that the control unit stops controlling, the indicator light doesn't light, and no heat is produced. It seems more like a controller issue than the heater element failing, but there's no way to determine this easily. At any rate, they DON'T work after about a year! And to be clear, during the WFIII cycles, the heaters kick on toward the end, and only run a minute or two. They hardly run at all in between cycles as the tanks are fairly insulated. I am not overtaxing the heaters!

********

The above mini-rant started because DK was preparing to post of a bird's eye view of Shrimporium progress, to date, because she has moved past some significant milestones in her global goal list.

Namely, at present, from a single water source (her carbonated well), she in the dead of winter now has Water Factory systems running to produce on the fly different waters that are successfully resulting in berried shrimp right now in the following tanks. There are three aspects to this that were part of the global goals that she has made significant progress on that she is sorta celebrating.
  • Waters for basically three different types of habitats from a SINGLE water source, made on the fly.
  • Water recipes made from cheap, easily available ingredients - almost nothing proprietary (the one exception is the fertilizer branch with includes CSM + B, potassium nitrate, and potassium phosphate ordered online).
    Everything else is cheap and DK can get within 5 minutes of where she lives either from a big box BORG type store or a grocery store.
  • Using the first two, she can get AT THE SAME TIME, rather different species into breeding mode.

She spent a couple of years trying out things and could get the neos to fly but the caridina weren't happy, or vise versa, etc., and this has taken quite a bit of problem solving. This in itself is not that difficult; the DIFFICULT part of it is she INSISTED on making a global water system with cheap, easily available feed vats (the injection concentrates from which she makes the various waters) that are fairly simple.

Right now, the entire system runs off 5 feed vats, and she's in process of transitioning this to four if her latest trial is successful. She makes feed vat concentrates once every few months, and it takes a few minutes a batch plus she stirs them overnight.

So when all is said and done, she is pretty darned lazy - no water changes, and only make 5 recipes of shrimp juice concentrate every few months. Not bad.

Wild Tigers
Red Tigers
Blue Tigers
Black Tigers

Crystal Reds
Crystal Papayas

Mermaids (Cardinals)

Orange Sakura
Fire Reds
Cherries
Yellows
Green Neos

Blue Bees

Now, granted, the berried number in most of these is very low as it's dead season not breeding season. DK was wondering why her berried rate isn't higher in her Blue Tigers, and this led her to start looking more at tank temps, which she has dialed way down. But on top of that, this morning she noticed that one of the Blue Tiger tanks is downright cold, and a quick check of above-mentioned heater in said tank resulted in learning that heater is kaput.

Last winter, she ran up against some barriers, namely that when the Water Factory kicked on while all the tanks were lit for the day, all the heaters would kick on during the cycle as cooler water entered the tanks. The combination of all the lights AND all the heaters running at once caused her circuit breaker to pop each cycle on colder days when the incoming water was colder. She has all her tanks on one circuit which is run into the emergency generator panel, this is why the breaker is not diversified.

So, as those of you who are faithful readers recall, last winter she took step one to ameliorate this: she built a heat exchanger for incoming tap water entering the WFIII.

Next, she shortened the WFIII cycle times, so less cooler water enters the tanks each cycle. This is a finely balanced thing, as the TIME of cycle affects a number of things: fraction of water turned over and therefore amount of water freshening, temperature dip experienced by tanks during cycle, relative fraction of carbon dioxide entering tanks each cycle, how much time heaters kick on and when due to cycle happening, etc.

Third, she dialed back winter tank temps, down near 70 (except for the Sulawesi bank of tanks). But this year, she wants to raise those temps back up toward 74, as the lower temps are depressing breeding.

So, she is doing a lot of prep toward power balancing the cycles.

This post is long enough, now. More on that later.

And one of these days, she'll continue the CJDS posts.

You know how you buy the kid, or the cat, the toy, and then they spend hours playing in the BOX? (And the actual toy gets ignored...)

DK's like that.

She got her first test LED bulbs in today, promptly took them apart, and now is entertaining herself staring at the funky lenses, imagining a really REALLY steampunk pair of goggles, made out of these, on her avatar shrimp, up there.

Because DK cannot stay OT, here is a picture of Shrimplantis, lately. While Amano-ites painstakingly and anally arrange elements in their tank, DK just lets whatever happen, run wild.

DK likes the concept of self-landscaping wilderness. Sorta like the inside of her mind, really.

For those of you who forgot, this was a tank she "emptied" to prepare to re-set, and then she got busy doing other projects and sorta forgot about it, except to toss some food in there when she feeds tanks. The microbabies she missed grew up and went forth and multiplied, as did the green.

Yeah. Green. Whatever it is.

The stuff that photosynthesizes, makes oxygen bubbles, and causes itself to float up toward the water-free "heavens" making an underwater volcano type landscape.

The shrimp seem to like it. So it's OK with DK.

Black tigers have been dancing for 4 hours, now.

Shrimplantis needs a theme song. Track 4 of QoW?

Flop ear was trying to be incognito, holding his ears back so they wouldn't be recognizable, whereas his Bro was stylin' wit' 'tude, loud-like and in-yo-face.

Without finishing the CJDS posts, which one of these days I will, I'll skip ahead to say the CO2 ends up liberated into the room air.

********

IN OTHER NEWS:

Dem black tigers were dancing the better part of the day. So long that DK finally took a look into that tank a while and saw this coo-el freak-o.

What is so coo-el freak-o about this black tiger variant, besides the pigment deficits on the skirt on both sides, is the fact that this guy has two front black legs with claws, AND THEN ALL THE PAIRS OF LEGS BEHIND THEM ARE WITHOUT PIGMENT. Totally coo-el.

She's gonna name that one "Bronco" - cause since the back legs are sorta not noticeable and the front legs are, it gives a sort of appearance of a rearing horse.

DK loves it when a shrimp has unique fashion sense.

******

Also coo-el, she found two more berried papayas she didn't know she had.
