#microwave sensor

[arduino-diy]

Proximity sensing is a very common application in electronics. There are several ways to accomplish this. The most common way is by using a PIR sensor. PIR Sensor senses the change in ambient infrared radiation caused by warm bodies. I have already covered this in my Tutorial No. 5: "PIR Sensor Tutorial - With or Without Arduino". However, since PIR sensors detect movement from living objects, they can generate false alarms. These sensors are also inefficient in hot environments, as they rely on heat signatures.

The other common methods of proximity sensing involve, using reflected ultrasonic or light beams. Using these sensors, the intruding object is detected by the reflected beam back to its source. The time delay between transmission and reception is measured to calculate the distance to the object. In this tutorial, we are going to look at another method of proximity sensing using "Microwaves" and "Doppler Effect".  In my hand is an inexpensive RCWL-0516 Microwave Radar Motion Sensor. The RCWL-0516 microwave sensor detects "any movement" from "any object" and does not rely on heat, making it more reliable in hot environments. I am going to use this sensor to create a Geo-fence around my house to detect motion and get notifications.

Webb Telescope Rules Out Thick Carbon Dioxide Atmosphere for TRAPPIST-1 c

NASA’s James Webb Space Telescope has conducted observations of the exoplanet TRAPPIST-1 c and made a significant discovery. Despite being similar in size to Venus and receiving comparable levels of radiation from its star, Webb’s findings indicate that TRAPPIST-1 c does not possess Venus’s thick carbon dioxide-rich atmosphere. If an atmosphere exists on TRAPPIST-1 c, it is likely to be very…

just wanted to hear you

summary jimin won’t stop calling even though y/n hates phone calls. turns out, she just misses her voice. it’s cute. painfully cute.

genre fluff / soft humor / clingy calls

pairing yu jimin x fem!reader

masterlist.

you were in the middle of writing a grocery list. that was it. nothing deep. just “milk, eggs, ramen, cat food—”

and then your phone rang.

not a text. not a cute “what’s the ramen flavor again” message.

no.

my wookiepookie is calling.

you froze. blinked at the screen. considered letting it ring.

but your thumb betrayed you and answered before your brain could stop it.

“hi.”

“hi baby,” she said immediately, all soft and sugary.

you sat there like. okay. fine. your list could wait. “what’s up?”

“nothing,” she said cheerfully. “just missed you.”

you smiled. like an idiot. “jimin. we saw each other like… two hours ago.”

“and it was the longest two hours of my life.”

you covered your face with your hand. she always did this. she knew you didn’t like phone calls. but every single time, it was this.

stupid, cute, make-you-blush-and-kick-your-feet energy.

“you literally could’ve just texted me,” you said, but it wasn’t even a complaint. more like a declaration of defeat.

“but i wanted to hear you,” she replied, like it was the most obvious thing in the world.

you were quiet for a second. the kind of quiet that only happens when your heart’s melting.

“…you’re lucky i love you.”

“i know,” she grinned. “and your voice is so cute. like, unfairly cute. you could probably cure sadness with it.”

“omg jimin.”

“like imagine me crying, and then i call you, and you say ‘hi’ and i’m instantly healed. just like that.”

you laughed, dropping your pen. “you’re ridiculous.”

“and in love.”

you covered your face again, this time from secondhand embarrassment. “you’re a mess.��

“a mess who wants to hear you talk about your day,” she said sweetly. “so. tell me everything.”

and so you did. not because you liked phone calls, but because she was on the other end. and when jimin was on the other end of anything, it suddenly didn’t feel so bad.

-

this became A Thing.

you’d be brushing your teeth. phone rings.

"mffhh?”

“just wanted to hear your sleepy voice.”

you’d be walking to class. phone rings.

“i’m literally on a sidewalk.”

“tell me what you’re seeing. are there any funny-looking birds?”

you’d be grocery shopping. phone rings.

“you did this on purpose.”

“yes. now facetime me and show me what ramen flavors they have.”

it wasn’t even annoying. it was just… jimin. clingy, soft, hopelessly whipped jimin.

and honestly, you couldn’t complain.

one night, you were lying in bed, phone resting on your chest, jimin’s voice on speaker.

you weren’t even saying anything. just listening to her talk about a documentary she watched where frogs could sense earthquakes.

“…like how? do they have mini sensors? is it frog intuition? babe are frogs psychic?”

you smiled, eyes fluttering shut. “you’re so weird.”

“but you’re listening,” she said smugly.

“always.”

you heard her sigh, gentle and sleepy. “you sound tired.”

“a little,” you mumbled. “but i like listening to you.”

“i like being listened to.”

“i like being liked."

“i like that you like that i like—”

“okay okay we sound like a bad poem.”

jimin laughed, the sound making your chest feel like a warm microwave burrito. “sorry. just feeling cheesy. you bring that out in me.”

you hummed. “you can call me whenever.”

“even when you’re busy?”

“even then.”

she went quiet for a second. then, soft as ever: “i really love your voice.”

“i really love yours.”

pause.

“you should sing to me one day.”

“do you want me to combust? i will literally turn into smoke.”

“worth it.”

-

the next day, she called while you were stuck in traffic.

“hey,” she said. “just wanted to say i love you.”

you nearly rear-ended someone from how hard you smiled.

“you’re stupid.”

“but you’re in love with me.”

“deeply.”

“say it back.”

“i love you.”

“you’re welcome.”

“for what?”

“for blessing you with my voice.”

you laughed so hard you almost missed your exit.

Smartphone cameras are NOT getting worse. (See below for phone photography tips)

I've now seen 3 pro photographers reviewing the iPhone 16 and complaining the cameras are "worse" and blaming Apple for not including revolutionary new camera technology.

And I suppose this is partly Apple's fault. Their marketing and hype machine always goes overboard. But also, that's just how marketing works. Samsung has a "200 megapixel" sensor and Sony has a "Zeiss" lens. And I think it is unrealistic to expect smartphone companies to say "This product has entered the iterative phase and each new model will only be marginally improved over the last one."

Smartphones (from any brand) have become an appliance. You don't buy a new model of microwave every year. And you don't expect every new model of microwave to have new revolutionary technology. And that is pretty much the expectation you should have with most computer hardware from here on out.

And in some ways, that is a good thing. That means the design of the phone has pretty much been perfected and it will last you a long time if you take care of it. You will not be left behind and your phone will be able to handle any new software for most of its lifespan.

So, is Apple getting lazy or is there a reason their hardware is stagnating?

It seems that neither money nor marketing can change the laws of physics.

They cannot make transistors much smaller. Phones and computers are about as fast as current hardware designs can make them (unless there is a shocking scientific breakthrough). From here on out, heavy compute tasks that are beyond your phone or computer will be done in the cloud on giant computer clusters. Thankfully computers and phones seem to be plenty fast for the majority of tasks we ask of them.

I remember Katrina telling me her new computer didn't seem any faster. And I explained the computing tasks she does regularly were not really affected by the increased power and speed of her new computer. If something took 0.1 seconds before and now it takes 0.05 seconds, that is twice as fast. An increase in speed that looks fantastic in advertisements. But it is hard for our brains to perceive. She just didn't do anything on her computer that took it long enough for her to notice. But having a faster and more powerful computer/phone will increase its lifespan and resale value, so it is still prudent to get the best things you can afford at time of purchase.

And I'm afraid smartphone cameras are hitting their own hardware limitations. They can't make the sensors much larger to get better depth of field and low light performance. And cramming in more megapixels doesn't actually add much more detail, if any.

It's physics.

Again.

You cannot get any more performance out of a small plastic lens. Why do you think pro photographers haul around 10 pound lenses still?

There is a formula for detail that never seems to be explained in any camera marketing.

Here is the simplified version...

Detail = Sensor x Lens

Let's say 1 is perfection. You have a sensor that performs at 0.5 and a lens that performs at 0.2.

The total detail will be 0.1.

But in the new model you increase the performance of the sensor to 0.8. WOW! That's so close to 1!

The total detail will be... 0.16.

Now let's imagine we've discovered a magic, physics-defying tiny plastic lens that performs at 0.8 as well.

The total detail jumps to 0.64!

But we all get sucked into a wormhole because we violated the laws of the universe.

Even if you were to design a near perfect (perfect is impossible) sensor that scores 0.99.

Without that magic plastic lens... 0.198

This is why I put Samsung's "200 megapixel" sensors in quotes. Because when paired with the same tiny plastic lens, there isn't much improvement. And that's why a 12 megapixel DSLR from 10 years ago with a giant honking lens can still capture more detail.

Most of the quality from smartphone cameras comes from the computational software processing. Phones actually take many photos at once and combine them to get you a decent image.

While that is still improving a little bit each generation, those improvements are stagnating as well. Until image processing can do a better job of inventing more detail realistically, smartphones are going to have to obey the laws of physics.

So... why are photographers saying the iPhone cameras are worse?

First, the ultra wide angle lens looks softer in low light.

And if you zoom between 1x and 5x, the images look less detailed.

But neither of those things make the cameras *worse*. In fact, the cameras are better for the most part. It's just that Apple decided to compromise on one aspect to improve another. Probably due to market research telling them most people prioritize certain things over others when taking photos.

They increased the resolution of the ultra wide angle sensor to match the detail of the main sensor, but that seems to have lowered the low light performance of the ultra wide. So in good light, you will see an improvement in sharpness. But they could not increase the sensor size to compensate and smaller pixels can have trouble with dim conditions. They probably discovered that people mostly use that lens in good light and they would appreciate the bump in detail more.

But pro photographers often photograph in more challenging lighting conditions because you can capture a more artistic shot. I don't think I could have gotten this shot on a smartphone.

But photo normies are just taking pics of their kids doing weird kid shit.

They aren't really trying to push the limits of their ultra wide angle lenses.

And they increased the zoom of the telephoto lens to 5x from 3x because most people never used the 3x. So images at 5x look great now, but unfortunately if you use anything between 1x and 5x, your image will be *digitally* zoomed. Which is never as good as optical zoom. They basically crop the photo, zoom in, and add sharpening.

So they prioritized people having longer reach and more zoom at the expense of that middle zoom range. Every camera system makes tradeoffs and compromises.

And I hate that I always feel like I am defending Apple, because they do have misleading and dishonest marketing regarding a lot of aspects of their tech. But hating on Apple gets more clicks so content creators also make misleading and dishonest claims.

And so we are just surrounded in a circle of hyperbole from all sides.

Now, if you know these limitations, you can change your approach to photographing stuff to keep them from being an issue. You can reap the benefits without dealing with the new compromises.

Here are some tips to help owners of the new iPhone, but also everyone else too.

Smartphone Photography Tips

Whenever possible, try to use the main 1x camera at only 1x zoom. This has the largest sensor with the most detail and works best in the lowest light. Only use the ultra wide or telephoto if you cannot get the photo otherwise. If you aren't sure you have enough light for ultra wide, take the photo, and then as a safety, take two photos with the main camera side by side and stitch them later with a pano app.

"Zoom with your feet" and don't use "in-between" zooms. Let's say your lenses do 0.5x, 1x, and 5x zoom. Even though you have the option to use other zooms, like 2x or 3x, that is going to compromise your picture quality. It is essentially going to crop your photo and enlarge it, which causes a loss of detail. If fact, if you use 4.5x instead of 5x, your picture will probably look like trash. You are always going to get better results if you can move closer or step back so that you are using the native focal length of your chosen lens. For example, let's say you are taking a photo and you judge the best framing to be at 4x. But you still have 10 feet of space behind you. If you back up and then zoom in to 5x, the phone will switch to that lens and you will get a much clearer picture.

Rule of thumb...

1 to 3x... try to move closer.

4 to 5x... try to move back.

If you hit a wall and end up at 4.5x, you might see if you have a panorama mode and try that instead. Switch to your 5x and do the pano. Or you can take two photos and then stitch them together with software later on. (Stitching panos with an app later will give better quality than pano mode, especially in low light.)

Low light needs stability. Get some sort of stabilizing device for low light photos. Either a phone case that lets you stand up the phone on its own or a mini tripod.

This thing folds to the size of a credit card.

Your phone will detect when it is stable and not being handheld. It will then automatically extend its shutter speed allowing it to drink in more light and give you a better picture.

Tripods are photography magic and will improve your low light photos quite a bit. Motion blur of moving subjects can still be an issue, but photos of a cityscape or landscape will look great.

For selfies, shoot a little bit wide and then crop in. This goes a little contrary to my earlier advice saying cropping lowers detail, but this is specifically for shooting a face. The 0.5x and 1x lenses on smartphone cameras are fairly wide angle. This can cause unflattering proportions with human faces. Wide angle lenses exaggerate distance. Near things look very near and far things look very far. To a wide angle lens, the tip of your nose looks like it is super close but your ears seem like they are a mile away. And that's why you may look a bit "alien" in your selfies.

People's natural instinct is to "fill the frame" with a face. The outer edges of a wide angle lens are more distorted than the very center. So try to keep faces away from the edges of the frame.

And one other trick you can do for selfies and pictures of faces is step back a few feet. Sometimes this is hard, especially with selfies, as your arm is only so long... but if you can take your face photos from just a little bit farther back, you will almost entirely eliminate unflattering distortion. In some cases, just stretching out your arm as far as it will go is enough.

Then you just crop the image with the framing you originally wanted, and your facial proportions will look great.

An example...

Here the distortion is bad because I am not in the center and the lens is too close to my face. The lens thinks my nose is really close and my ears are in Canada.

But when the lens is farther back the edge distortion is less prevalent and my nose and ears (relative to the lens) seem roughly the same distance away. So my proportions look great, but I don't quite have the framing I want.

But with a little cropping...

For social media there is still plenty of resolution to crop in. Cropping isn't bad, it's just always better to use it as a last resort or in a special circumstance like this. I get roughly the same framing as in my wide angle shot, but I don't look like I'm behind a door's peephole trying to sell you the Good News.

I wish they made a "mini" selfie stick that only extended a foot or so. With the main camera that is usually all people need to undo any wide angle issues. I have one of those mini tripods and that works well, but there is no activation button so I have to do a timer. Mirrors work great to help you get some selfie distance.

In any case, all cameras have limitations and compromises. Clickbait titles saying something is WORSE THAN THE OLD ONE are frustrating and wrong.

And people upgrading phones every year are silly. All current name brand smartphones have promised at least 5 years of software updates. I think Google and Samsung are offering 7 years on some models. And Apple has always just let you use your phone until it literally will not work with new software. Which has worked out to 8 years in some cases (with a battery swap).

Phones are now appliances. For now, hardware will improve 10 to 15% from generation to generation until physics breaks. So if you want a 50% improvement, wait 5 years and you'll think your new phone is awesome. If you upgrade every year, it is going to be difficult to see the change.

I hope to be starting a little course on smartphone photography in the near future. All modern phones are capable of taking amazing pictures. And as long as you understand their limitations you can mitigate or avoid them. And that is what I plan to teach.

I'm fascinated by the implications of Marnie having sensory issues. I should stop nerding out about robotics to you tho

(Never stop I love it)

The bots all can process sensory information like touch/heat/pain to discourage just getting blown up repeatedly in battle (you can hear them cry out in pain when shot or on fire). Though if you play a round of mvm, you can see they're generally not intelligent enough to actually avoid attacks on purpose since they have numbers advantage, so its not usually all that helpful. But regardless, the rogues have it as well.

All the bots are unused to actually wearing clothing, but Marie in particular just hates the feel of it. She can look like whatever she wants on demand so having anything extra on her just feels like it's slowing her down and distracts the hell out of her. Her pain tolerance is abysmal as well. She accidentally clips her elbow on the doorframe and she becomes a bedridden Victorian matron dying of tuberculosis

Bolts and finn have pretty high tolerance for pain and regularly exercise it by doing stupid shit. Bolts is constantly getting mauled by wild animals for fun, while finn repeatedly crash lands his trimping attempts. When not getting hurt, Bolts is a huge fan of just touching everything in reach which usually doesnt exclude much. Especially stuff that's outside. He loves textures of tree bark and grass and moss n shit. Finn meanwhile had to learn to navigate by touch, either hands on or via his sword. He HATES uneven pavement and gravel.

Hans probably has it the worse cause being sapped made his sensors go haywire. It'll fluctuate from being literally unable to feel at all to oh my god do not touch me don't even look at me. For some reason it's worse if someone turns the microwave on. He gets especially upset by any sort of internal sensations cause then he thinks about it too much and scares himself

James Webb Telescope Unveils Cosmic Seahorse and Gravitational Lensing

Webb Gravitational Lensing

NASA’s James Webb Space Telescope has captured a mesmerizing image that reveals a cosmic phenomenon known as gravitational lensing. In this captivating image, distant galaxies are magnified, distorted, and brightened due to the gravitational pull of a foreground galaxy cluster. Among the intriguing features highlighted in the image is a galaxy nicknamed the “Cosmic Seahorse,” presenting a long,…

A recent article in The Defender reported a new capability of wireless devices: seeing and hearing, even without cameras or microphones:

“It’s about following the waves as they go outward from the transmitter and seeing when they bounce, get slowed down or get absorbed. You can, with sufficient computing power, draw a 3D image of what is inside the beam and then proceed to identify it.”

It acts like radar or sonar, but besides giving you a visual without any video or camera, it also can give you sound.

“transforms smart devices into advanced virtual sensors”

“we could pick up breathing, monitor sleeping, detect a fall, recognize gait patterns, and even pick up sound without a microphone.”

But the worst part is that you do not need to own smart devices like a cellphone or a screen TV, because your residence can theoretically be hit with radiofrequency/microwaves from the outside — in order for strangers to be able to see and hear what is going on inside of your home. This type of thing results in a complete loss of privacy.
