And I'd seriously doubt that there's three more sets of hands between digikey and the manufacturer in order to get that approximate one cent price point.

Someone didn't figure it out, it's like tons of people found different things and thousands of companies and people did develop it into a better product. It's too much for one to perfectly make a product like this. You have what have been developed before within years and the knowledge gathered from around a hundred of years to put on.

It's an alarmingly simple process when you know the mechanics of it, but how we got to understand that is the part that impresses me. But, technology has a way of making you forget just what exactly you're dealing with from a basic perspective. Most people probably don't think much of a smartphone, but it's effectively pure rare metals, minerals, and essence of dinosaurs powered by man-made lightning that uses light-speed pulses and audio waves far, far beyond our hearing to allow distant communication and access to all human knowledge in seconds. Imagine explaining this to the richest person on earth 200 years ago. There's no way they could conceive of what you're saying. And, of course, by the ever-increasing speed of advancement, something that will be made 50 years from now is probably impossible for us to currently conceptualize.

There are many things that seem impossible to me even now, like how th is it possible to be able to interact with the contents inside a screen, and the technology behind earphones and planes and cameras and videos. Everything we have now is so amazing. We went from nothing to everything. Imagine, before there were only paintings to keep portraits, and early in the 19th/20th century we were able to capture reality and view it.. and then it evolved to videos, a moving picture that is seamless.. And there's also audio. Before we only just heard, and now we get to capture the voices, the sounds of reality and store it for however long we want to. It's amazing. We have come sooo far.

@@NoeOfPortland Math is the foundation for everything, even other STEM fields like chemistry and even socioology. History is important for obvious reasons. Don't need to replace them, we could add more core subjects. Problem is it wouldn't help you pack packages in a warehouse, so we only get basic curriculums sadly.

@@NoeOfPortland I appreciate your perspective, @NoeOfPortland. Incorporating practical tech education into the curriculum could indeed be beneficial, as it aligns with the increasingly digital nature of our world. Having a foundational understanding of electronics, such as the implications of milliamperes on battery life, can empower us to make informed decisions about the technology we use daily. As someone delving into computer systems in post secondary, I've seen firsthand the value of such knowledge and believe it complements traditional subjects by providing a more holistic educational experience. There just needs to be more effort from everyone. kids need to study more, teachers need to teach better that way we can use our abilities and our brains to their full extents, I believe we should learn history, math, science and technology and we should also focus on innovation but broad innovation.

There’s actually a smaller mic with about the same battery life, but much smaller than that. Your house could have one and you will never know, no matter how much you clean, you’ll never find it.

Fun fact: all microphones are speakers, and all speakers are microphones, IIRC. They work horribly, but if you can push enough energy through the membrane of a speaker, its movement will apply signal to the wires, just like a microphone.

You're remembering incorrectly. Microphones and speakers are functionally the opposite. Speakers tranduce electricity into sound, while microphones tranduce sound into electricity.

@kuboskube

@@ChaceBonanno remember, every action has an opposite reaction. For a speaker, pushing waveforms through a wire causes a magnet attached to a diaphragm to move accordingly. Likewise, if you impart waves upon the diaphragm manually, it will cause the magnet to put waveforms back into the electrical wires. With an amplifier, you *can* read this signal, meaning that speakers are, no matter how horribly functional, in essence, microphones.

It amazes me that we can produce these technologies in mass quantities. Just imagine what technology we have the public doesn't know about

I always wondered how they work, and now I know! Tysm

This episode was actually crazy! Thank you so much for everything, it is so much appreciated.

Now you know, anywhere you are, there can be a tiny little pin hole recording everything. A high corner in a ceiling, wires ran behind wall to a power source and transmitter. A drawer knob. A tv remote, which already has power and enough room to stuff a small pcb to the power and transmit. Underneath a handrail in front of a motel/hotel room where you might go smoke (nasty). Your favorite barstool, underneath powered by a small button battery that can last a week. All real scenarios. Which I think all the time about. Also, it’s the things you do when know one’s looking that can really define you as a person, but to yourself.

Is the top layer deposited on the stationary layer after the hole are etched? Or is the whole thing manufactured the other way around and glued shut, since then you could do the ion etching for the cavity beneath?

Manufactured "bottom up" in layers. They would have used some kind of sacrificial layer to provide the spacing between top/bottom. Probably a layer of silicon dioxide glass. So you etch the first pattern, deposit a layer of glass, deposit the next layers of poly-Si, then finally etch out the sacrificial glass layer (using HF or plasma). Once all that was done, they probably flipped the entire wafer over and did backside DRIE etching.

Batman must be informed of this technology 😂

It’s crazy how much technology I use on a daily basis, that I just don’t even question how or why it works.

Its a real 'micro'phone now

So that's why some sound so good? After all this time, I never knew they were capacitive mics

This is the same type of microphone that’s used in pretty much any phone. On iphones if you remove the simtray you can see one of them, it’s the ambient/noise cancellation mic, but the same model is usef at the bottom for your voice and next to the rear camera.

@SubjectiveObserver Sure, let's take hidden cameras that are often used by stalkers in hotels. They're often not uploaded directly to the cloud because of the small discrete places they are hidden. They're left there for a long time running only on battery till death, and store their videos on a memory card, probably being a MicroSD being the smallest there is currently for the people's use. Why can't they do otherwise? Wifi requires an antenna plus a bigger onboard motherboard that has to be binded to a server that is either a satelight or the hotels wifi which would be rather difficult to set up, this means the camera is going to be much larger as whole due to the nature of more components, ETC ETC. I'm not going to reply anymore to this dumb argument

I'm convinced that this is old recovered alien tech that humans slowly release until it's outdated, then the next version comes out

This is why technology is amazing to me. When it gets cheaper over time and better
