To clarify: the intent is to install a low frequency sounder beside the smoke alarm and use the low frequency sounder to meet the decibel requirements, as this will produce a less piercing tone. NFPA 72 permits fire alarm notification appliances to be used for this purpose. Therefore, it would be...

I'm fairly new to Blender modeling and I'm following a Blender Guru Chair Modeling Tutorial. At Some Point, I realized there were weird shading artifacts in my geometry, as you can see in the picture. I'm pretty sure there are no unnecessary vertices overlapped and the face that has shading prob...

I am trying to do a project using Raspberry Pi Pico H, that will work as a pulse oximeter. I have designed the circuit in the image (note: the exact pins on the photo might not match with the code because I have changed it several times, but trust me the pins in the code are what I have connected...

Earlier today I noticed a notification appear in my iPhone's Notification Center. At the time I had something to do, so I didn't check it right away. A few minutes later, I went to check the notification center only to find the notification was gone before I had a chance to read it. Is there a wa...

In other words is there potential for it to perform significantly better than expected when first tested in space?

$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 20.04.6 LTS Release: 20.04 Codename: focal $ uname -r 5.15.0-125-generic I am trying to work with coq theorem proof assistant installed with snap using Emacs and proof general. Unfortunately, I got...

I downloaded an image from iCloud, which ends up as a zip file containing a JPEG file and a MOV file. This is because the iPhone takes a motion image (MOV) over a brief interval of time, and then generates a JPEG still image. Firefox complained that the file contained malware, which required me ...

So I am aware that you can create a custom property directly in Blender, and use it into an Attribute Node, but in my case, I would like to try to use my pointerproperty as an Attribute, it is written in python and is of type Object. Here is how it is in Python: from bpy.props import PointerProp...

Where does Environment Canada have weather stations in Ontario? Specifically, weather stations that are used to create Environment Canada weather forecasts. There is a map on this page: https://weather.gc.ca/forecast/canada/index_e.html?id=ON But I don't think the map includes all weather statio...

I'm making a universe where game tropes are justified. One of them is dungeon food. In many videogames, the protagonist can find meat behind breakable walls and all sorts of random areas. This food is always edible, never goes bad, and is in a great, hot condition. Pests also never reach and eat ...

A！？ 君…！　死んだとか、法事の場で　忌み言葉を発してはいけません！」 B「こわぁい……助けて…」 C「まぁまぁ君たち」 A「まぁまぁと繰り返しを連想するのも忌み言葉です！」 The dialog is a back and forth between 3 people. They are at a funeral. I used the letters to show who is talking. I'm stumbled on how to take the last dialog exactly. The character seems to complain ...

I'm trying to scale a digital I/O output from 0-3.3V to -1to-2V. I've decided to use an opamp inverter configuration so that 3.3V maps to -2V and 0V maps to -1V. This would give: Vout = -0.303 * Vin - 1 So I've designed the following schematic with a gain of 0.3: The input at R1 is connected to ...

I am trying to understand how the height/width of a rule is determined in LaTeX. Here is the example below: \documentclass{article} \begin{document} % This \hrule is as long as the following box (string) \hrule height 1pt As a philosopher, he was a leading representative of 17th-century rational...

So here's my question which I got from a practice problem set on Elliptic Curves. Let $E:y^2=x^3+ax+b$ be an elliptic curve over $\mathbb{F}_p$ ( $p$ is prime $>3$) For which polynomial $x^3+ax+b$ does $E(\mathbb{F}_p)$ contain Klein's-4 group as a subgroup? My approach: I can figure out such c...

I am currently reading Chapter 2 of Theoretical Astrophysics Vol 1 by T. Padmanabhan. Here he discusses integrable systems in Hamiltonian mechanics. The idea of angle action variables are introduced as a convenient tool to study integrable Hamiltonian systems. However I do not see the usefulness ...

I have heard that the following is a "well-known" Claim. Let $M$ and $N$ be smooth manifolds with equal dimensions and $M$ compact. Then a generic smooth map $f\colon M\to N$ has finite fibers, i.e., $f^{-1}(n)$ is a finite set for all $n\in N$. (Here "generic" is with respect to the $C^\infty$ t...

My dryer has its own 30 amp 240v circuit in the panel box, wired using a 10/2 Romex and 3-prong receptacle. I plan to replace the 10/2 Romex and 3-prong receptacle with 10/3 Romex and a 4-prong receptacle for better safety. Currently, when coming out of the panel box, this 10/2 cable is bundled w...

Within my setting, magic exists as a system of writing that has to be encased within a circle. Usually, these circles aren't any larger than the writer's hand. However, the primary villain of the novel is attempting to create a magic circle large enough to affect a continent, and plans to do so b...

On a sheet of choir music, how do you interpret a stem with 2 heads? For example, on the bass clef staff, who sings the note represented by the top notehead on the stem, and who sings the bottom one? Example:

I've been in 70+ Nights, and used Changes of Fate tons of times, but only saw Price of Midas once in the Well of Charon, and without enough Life to buy it at that. People online seem to say that it really is just rare, even in the first game, but might there be conditions attached to finding it? ...

The queston is: Can one produce Pantone Metallics with LaTeX? And how? We have been looking at the three packages: colorspace, spotcolor and xespotcolor and they all seem to define the Pantone colors via (or using) the CMYK values. An example from the colorspace package is: \AddSpotColor{PANTONE}...

I vaguely remember watching a cartoon movie whose plot goes like this. The movie begins with a boy named Hans and a girl (I don't remember the name) playing on a meadow. The girl's kite gets trapped on a tree, and she asks Hans to climb on the tree and free that kite. Hans refuses to do that unle...

I am trying to prove the following: Let $H$ be a Hilbert space, $Y\subset H$ a closed subspace, and $x \in H \backslash Y$. Then there exists a unique $z\in Y^\perp$ with $\| z \| =1$ and $\langle z,x \rangle = dist(x,Y)$. I know that I can find a unique vector $y\in Y$ with $dist(x,Y)$ and ...

I asked my supervisor about how plots used to be made before computer graphics were a thing, and during this discussion, he showed me a plot from a 1933 book "Tables of Functions with Formulae and Curves" by Jahnke and Emde. Here is the plot: My question is, how were these plots made? In the pre...

The features clause in the datasheet (https://www.microchip.com/en-us/product/atf16lv8c) specifically mentions "Inputs are 5V Tolerant", but the DC characteristics specify VIH to be MAX Vcc+1 It's unclear whether I can power this chip using 3.3V and still be 5V input tolerant. I would guess tha...
