WHAB’s 1924 Brick Schoolhouse RDWC

When arriving in the 2G Repair Station left wanting, I went with plan B…

In lieu of the proper tools, I was left to improvise a bit.

I grabbed my X-Acto Knife knowing I had extra blades in my tool box…

I hadn’t open that knife in a very long time. Maybe decades. I never needed to. Well, it was locked up…forced compliance was required.

I grabbed that first set of new blades only to discover that package is for the wee twin of this knife, the small one in a set of 2.

I grabbed a second set of new blades (red topped), knowing exactly where they were. It’s the same size blade as the previous too small knives. I wound up used the old knife blade as a table and the small new blade in the too big handle to cut 2 of flaps off of the X opening I had made in it and narrowed one side making it more like an hour-glass.

You can see my cuts below…

This is with the LEDs on. With the flash but it might be different because I also had the desk lamp on.

I think that should work, and IF not, I’ll use it as a template on 3G! winky

Okay, I’m going in for Trichome pics!

I think my PC browser is going to crash. I’m going to force crash it and restart it before it does. It’s about a 1/2 hour ordeal.

I’ll brb, approximately! ROFLMAO

I forgot to crash the browser before I went in…facepalm I had to do that and wait for it to reboot after I got back to my desk…many, many wasted minutes. Sorry.

Garden II Flower Day 60 - Trichomes

To be clear, I’m still standing with Mostly Clear, Cloudy with a Hint of Amber. Still just a hint, imo.

I started with the Runt, I forgot my Steady-Stick, the first few are the Runt, the last few are #6 Bubba Kush. The in between are clockwise from the Runt but no demarcation. No individual shots of each individual Girl. I’ll try and get that done sometime today :crossed_fingers:

Sorry for some of the blurriness due to being unsteady.

And, @JoeCrowe…I plan to cut my way in there the next time I go in. I’m hitting those two Girls pretty hard going in and getting back out. I may as well sacrifice them instead of beating them to death first!

ROFLMAO

They’re low on the plant but they’ve been there for a long while.

I was crawling under them at first, now I find myself sort of barging through! It’s like Free Slurpie Day at 7/11 on 7/11 in there! winky

@Gpaw, my friend. I still want to thoroughly re-read your message before responding. I want to have as firm a grasp on it as is I am able on it beforehand, please. winky

IF other than maybe responding to this post, my next post will be in response to your carefully composed message. Probably later today. My apologies.

Good morning!

First off, Thank You for taking the time for your considered response. tup

I really appreciate it! I apologize for the extended delay in my response. It was unavoidable.

I’ve read it. I’ve reread it. I’ve reread it again and again.

I understand some of it.

I’m not seeing what I should set my offsets at for AC #3. For instance and example: If AC #3 is indicating 54% RH what is the actual RH (or as close as one could get short of a Correction Table) for on the ground interpretation.

IF AC #3 is indicating 48%, for instance, how is the user to interpret it?

I tried my best to get the full understanding of your most helpful composition.

As near as I can tell, in your graciously provided chart, the intersection occurs nearer to the upper range of the 2 test parameters and that is where it is the most accurate, true reading…for this given device at those test parameters.

Sorry if I fell short.

It would be better IF AC Infinity provided offsets for upper and lower ranges. The Acurite sensors do. In fact, they’re offsets are in the tenths for Temperature and Humidity in + and - numbers.

I do sincerely thank you for your efforts and your contribution to the discussion,@Gpaw! tup More than is expressible digitally.

You can think of the ‘adjustment’ of the controller as simply moving the AC#3 line up or down in relation to the 45 degree perfect sensor line.

Now if you have the capability to adjust two points, then you would be changing the slope of the line and you could ‘force a fit’. That would be a much better solution.

For your examples, AC#3 = 54% the actual is about 51~52 %.
I find 54% on the Y axis, trace a horizontal line at that 54% across until you intersect the AC#3 line. In this case the AC#3 line is above the Perfect Sensor Line (PSL) so you drop vert. from that intersection point to the PSL line and read that value on the Y axis.

If AC#3 = 48% the actual is about 44%.

If the AC#3 = 85% then the actual is about 90%. In this case the AC#3 line is below the PCL so you go up from the intersection to the PCL to get the correction value.

The math solutions are more precise. The simplest is essentially doing what I explained above once you charactercize the line (Y=mX + b).
And then there is the polynomial spline fit… That constrains any response curve to the PCL over the specified data set.
We don’t want to go there… Trust me… :laughing: :vulcan_salute:

I updated the drawing to better illustrate for the 48% = 44% actual and 85% = 90% actual examples.

The 35% and 75% were from the original calibration tests you did.
That was using the offsets you measured to establish the AC#3 line.

HAW!!

That’s on me for not checking my work… :rofl: :vulcan_salute:

I was thinking this morning it would make more sense to update the drawing than you trying to decipher from the text alone.
Of course, enlarging the drawing would help or doing it through math, even better.

So long as the sensor doesn’t drift you can get reasonably accurate numbers. If the sensor does drift you just need to re-plot.

How to squeeze +/-1% data from a +/- 5% sensor… :+1:

The graph is really helpful!

So, for instance, IF the probe was indicating 60% it would actually be 58% (where the 60% indication intersects with the PCL?

And, that was another issue I am puzzling over…

Wait, that probe has a +/-5% accuracy?

AND, your WONDERFUL work would need to be changed WHEN this probe drifts, IF it drifts?

THANK YOU, my friend…sincerely!

The intersection point is where measured % = actual %. As you move away from that point a correction needs to be applied.

I’ve shown the intersection at 65% So if you are measuring 60%, actual would be 58%.

I see another error, I called it PSL in the texts and PCL on the drawing… Good thing I’m retired or I’d have to fire myself… :rofl:

That looks about 5%, didn’t the AC Infinity folks say +/- 5%?
Basically what that means is they can shift the response up and down to they get it within +/-5% at the extreme ends.
It sounds kind of crappy but considering how these sensors work, it’s not that bad. Especially if you apply a two point correction (changing the slope) instead of a one point correction (shifting it up or down).

To be fair, it might have been a compromise forced on them (e.g. not enough room for the code) as apposed to someone taking a shortcut.

Everything I see from AC Infinity suggests to me it is an Engineering driven company with good marketing as apposed to a Marketing company with engineering support. A subtle distinction, but an important one.

I just looked at their site after I read your post and I don’t see any mention of “accuracy”, which I find odd on a instrument of measure.

But, ALL of that can change the next time I perform the test?

Your work would need to be recalculated, redrawn?

You’re HIRED! winky biggrin

I only mowed 1/2 the lawn. The grass went dormant for a couple of weeks a couple of weeks ago. I was starting to think we were going to have a shortened mowing season. NOT.

I’m going to save your graciously produced chart, IF that is alright with you?

Just 2 more questions, please.

Given that AC #3’s 75% RH Test of 07292022…indicated 1% under the 75% test on that date at that time - 75% = 74%, no?

I’m not sure why you represented a 5% increase.

And, ALL that information - ALL your greatly appreciated work - ‘may’ change, correct…and likely will?

Thank You!

Edit Add: Btw, my friend, my noticing the minor 32/35 oversight proves I was reading your effort and running the numbers through my Lunkhead! winky ROFLMAO

I wasn’t around much yesterday for 2 reasons.

One is I was in the garden for hours yesterday, cleaning things up and trying to untangle the Girls. The days of their commingling fraternization is over!

#6 Bubba Kush is even more of a BEAST than I thought!. Wow!

But, I did notice some weak growth behind #5 Afghan Kush on that back wall.

Which actually brings me to something I’ve been thinking about for some time now.

I ‘may’ buy a Light Mover. I think having their Sun move about and providing light to areas that seem to be lacking it, maybe.

I’m going to cut all that poorly performing and weak undergrowth out.

But after my trimming session last night/this morning I did remove that lower branch I mentioned that I would take out to bring to the desk.

It’s not a great image, in fact…had I seen it while I was in there I would have deleted it and taken another picture…

It’s a broken branch - broken from my failed belly crawl into the center early on in the grow! ROFLMAO I left it in place just to see what it would do, it did continue to grow, btw. I’d been brusquely passing between her and her neighbor to the left #2 Bubba Kush this entire time, first crawly beneath them, then just barging through.

In fact, I really don’t like the idea of being in there so often in the first place - I’m sure I am causing damage, not that I’ve seen any short of that one branch.

Being in center does provide a great opportunity to trim or to just look at them…I just don’t like it.

Here’s what she looked like under the digital microscope.

The seemingly obvious cloudiness it not accurate, imo. I think it is just refracted light. There certainly is some cloudy trichomes but it is not populated as the image would indicate.

I’m thinking about trying ONE more Digital Telescope.

This one has all the attributes I ‘think’ would benefit anyone working in their garden for trichome inspection.

It has adjustable LED intensity. It has a nice large, and easy to reach Focus wheel AND the “Shutter” button is on the very end of the microscope for ease of operation, I believe. I think I read the shutter is an Induction button, I think.

It looks like a better ergonomic fit, especially for one hand operation.

I did Loupe all the Girls last night/this morning. My opinion stands at this time - Mostly Clear to Cloudy and a better hint of Amber…still just a hint.

And the other thing I did was correct a mistake on that 2x4s Basic bench kit. A mistake I made when I first assembled it.

It’s taken now to correct it because it wasn’t critical to anything I was doing AND a person would have to nearly dismantle the entire thing to fix it. Except for the top shelf the shelves MUST BE installed as you build it. Reverse to fix your mistakes!

I’m not entirely sure how it happened.

This bench wound up being 1-1/2 inc too wide.

One would presume I had not allowed for the width of the 2x4 materials used.

But, IF that were the case I’d be out 3 inches

So, I had to take it pretty much apart and re-cut all 6 short stretchers. And to keep the cuts balanced I had to take off equal amount from both ends of the stretcher and get new wood on those ends to re-screw into them.

Hopefully this shows what was going on…look at the white top but also lower 2 shelves.

The above picture is when I rebuilt the one end and about to start on that far end. The lower shelves are trapped in there. I had to do the rebuild work around that point.

I had to lift both ends up like this just so I wasn’t working on the floor…

I did wind up using the stiffener method 2x4s Basics recommends. I had a piece of 2x4 nearly exactly the size I needed, I only had to shave off a little more of the bevel cuts just 2 times to get it to fit perfectly. tup

However, my FIRST bevel cut with the TS75 on this Qaud MFT Hinge System system took out the Under Guide Rail Fence Support. It supports the end of your cut under the guide rail nearly to the very end of the BenchDogs Fence. It’s a great accessory to have, was a great accessory to have had! ROFLMAO

Pretty much destroyed it! frown It’s only $16 but it ‘may’ be $16 to ship it! ROFLMAO

But, it’s done.

BUT, last night I decided I MUST get that bench across the to that nearest wall behind it. Where it is at now is not agreeing with me at all.

The longish stuff is going back to where I moved it from the last time I moved it! ROFLMAO The longish materials are going behind the Jointer.

And, I ‘may’ switch them around. Put the 2x4s Basic bench where the Multi-Function Slab is now and vice versa.

And, I have decided to modify the Slab Base. I want to move the vertical front legs farther apart. IF I can get another approximate 8 inches in between them then that extra shelf from the Multi-Function Slab kit will fit underneath where it was designed to be and I believe would benefit the work just by being there to set things on while working at the Cutting Station.

Continuous Improvement!

Then, here’s a WILD idea I’ve been mulling over since I decided to keep the EXTRA long benches in the Classroom (2 years?).

I ‘think’ they ‘may’ make a great bookcase set on end and joining them, their bottoms together.

WILD! ROFLMAO

I’m pretty sure I can do it without mangling them too much! winky

That’s all for the moment until I remember something I had forgotten! ROFLMAO

I’m going to go change the Res. out for the final push.

Edit Add: I knew I’d forget something! ROFLMAO I have inserted the picture titled Shop Shuffle 0032.

IF I don’t, I’ll be subjecting the Girls to out of cycle light. I don’t want to do that.

That’s correct.

Probably not, at least not for a while. The sensor will ‘age’ so the characteristics will change over time. Chemical vapors can mess it up as well. So a good idea to check once or twice a year.
