We've essentially tricked rocks into doing math with lightning.

because those rocks can use electricity to think, hence we programmed them

@@Mrshoujo semiconductors come from rocks/soil

Whoa... I feel VERY old now.

truly nuts.

Thats the way it has progressed, you start with making a machine that can make parts more precisely than a human with hand tools then you use that machine to make more precise parts for a new machine, then you use that new, more precise machine to make an even more precise machine, and it just keeps on going until you cant make a machine any more precise or there isnt a need to make it more precise. Of course it is more complex than that and involves multiple types of machine but that is the general idea, just keep using your machines to make even better machines and then we eventually end up making things on the scale of atoms.

And yet this tech is HUGE compared to CPUs and the like. This is micron scale, not nanometer. I was surprised seeing them just shine light through a mask without a hugely complicated lens system, but their features are just that big, hundreds of times bigger than the smallest they make elsewhere. But of course it's a relatively simple device, so size isn't a concern, and it needs to be build "big" due to the mechanical parts.

That fact that they are running into a diffraction limit and have begun to use hard UV is insane. X-Ray photolithography is the next step and it’s truly insane to think about.

Im a lithography technician its really cool to see how the machines work

Umm what? The sensor has no idea where it is and it doesnt matter. They typically measure acceleration (accelerometer), angular velocity (gyroscope) or magnetic field strength (magnetometer), none of those measurements allow the sensor to know where it is, it just allows the sensor to measure those quantities. On Earth, an accelerometer can be used to measure gravity and calculate the pitch and roll angles amongst other things, integrating the gyroscope measurements is also a way to get a relative angle of rotation and the magnetometer can be used like a compass to calculate the heading. The accelerometer gives absolute measurements in reference to the Earths gravity, the gyroscope only gives relative measurements and the magnetometer gives absolute measurements. Even combining all three measurements it is still impossible to know where the sensor is, only what kind of environment it is in, the only information that you can calculate from those measurements to know where the sensor is, is the pitch and roll angles and the heading it is facing in, that isnt anywhere near enough to know where the sensor is only its orientation. Phones know where they are mainly through GPS, they know their orientation based on the IMU. Also most sensors still dont perform much calculation on the sensor chip itself, it is usually another processor that reads the sensor data and then performs the calculations, although it is starting to get more common to have processors built into the sensor chip.

@@conorstewart2214 you are incorrect. You should educate yourself.

@@conorstewart2214 since you won't actually look it up, your type NEVER do, here is the full explanation: The sensor knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is (whichever is greater), it obtains a difference, or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the sensor from a position where it is to a position where it isn't, and arriving at a position where it wasn't, it now is. Consequently, the position where it is, is now the position that it wasn't, and it follows that the position that it was, is now the position that it isn't. In the event that the position that it is in is not the position that it wasn't, the system has acquired a variation, the variation being the difference between where the sensor is, and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the sensor must also know where it was. The sensor guidance computer scenario works as follows. Because a variation has modified some of the information the sensor has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it knows where it was. It now subtracts where it should be from where it wasn't, or vice-versa, and by differentiating this from the algebraic sum of where it shouldn't be, and where it was, it is able to obtain the deviation and its variation, which is called error.

@@mgancarzjr I know how these sensors work. You are confusing applications from how the sensor itself works. In most cases the sensor just outputs the raw values, it is up to another processor to perform calculations on that, although sensors with built in processors are becoming more common. Also none of what you said has anything to do with the sensor knowing where it is, it still doesn’t know or care where it is, all it measures is acceleration, angular rotation and potentially magnetic fields, those can be used to calculate relative motion and orientation, but the sensor still does not know where it is, and the sensor measurements can still not be used to tell where the sensor is. You also get drift over time with these sensors, even when integrating the acceleration, since you are quantising and discretising continuous motion. If the sensor knows where it is then why can you take some measurements, move the sensor and take some more measurements and have them be the exact same when in two different locations? That is because the sensor does not know or measure its location, it measures acceleration, angular velocity and magnetic field strength, that is typically all they measure and it is not enough to tell the location of the device, it is enough to calculate relative motion and orientation but that is it. What you seem to be on about is using the sensor as part of a bigger system and using it for some form of position hold, that can work in some cases but in a lot of cases it is nowhere near accurate enough and is subject to drift. Most drones despite having IMUs rely on the GPS or an optical flow sensor to implement position hold, not so much the IMU. The sensor itself does not measure where it is and cannot measure where it is, what you are on about is integrating the acceleration or angular velocity to get relative motion and correcting for that, but as I explained that is generally an inaccurate method. It is also not how the sensor works, that is generally another processor carrying out the calculations. Edit: also how do you know my type? You seem to be the type that thinks they know everything when they really don’t. I have used these kinds of sensors quite extensively.

@@conorstewart2214 ask me how I know you didn't do an ounce of research on this subject. Your type NEVER do.

There’s no “mechanism.” It’s a matter of X, Y, Z “diving boards” of a few molecules. They bend because of inertia when the chip is moved. Sensors report the movement.

@@BitSmythe Isnt that litterally what Mems are though? Mechanisms?

@@honkhonk8009 You’re right, I thought a mechanism required motion. Well, it is. A fixed lever IS considered a mechanism.

@@BitSmythe There is motion though, the motion is driven by the environment and inertia not the chip itself. Bending is a motion too.

@@BitSmythe They're called electro-mechanical sensors (MEMS = micro-electro-mechanical systems), because they work by mechanic bending motion, like you say yourself. This is a 6-axis sensor, 3 gyro and 3 accelerometers. Search mems gyro on youtube, there's a bunch of good videos showing how they work. The gyro part vibrates by itself, in order to detect twisting motion induced by gyroscopic forces.

Yeah they didnt show the actual motion sensing parts of the chip or how they are made and it does differ from making normal microchips since MEMS sensors are 3D mechanisms, but this video shows none of that.

It is a minor error, the accelerometer, along with the rest of the IMU is used to measure and detect motion and orientation. Some IMU chips even have built in functions to trigger interrupts when certain motions or gestures occur, so they can be used as motion detectors. Some sensors like the STM ones list motion detection as a feature of the chip.

Unfortunately they skipped all the interesting bits, this is pretty much just a basic overview of how a lot of silicon chips are made.

Inertial guidance was already around back then, this is a lot longer ago than you may realise. I have the same problem, "60 years ago" still means 1930 to me, somehow. Every year with a two at the start just sort of blurs together.

Sounds like a name for someone's pet

What kind of robots do you make? Is it a hobby or your profession?

@@conorstewart2214 I am an author of published robotics books - my most recent being Learn Robotics Programming second edition, with a new book Robotics at Home With Raspberry Pi Pico due soon.

Anything that has something to do with microelectromechanical systems (MEMS) I'm a microsystems engineering student, and I've been to our campus's small cleanroom multiple times. wearing a full-body clean suit is mandatory but the AC is running constantly so it's not too unpleasant.

It's either a gyroscope or a basic accelerometer. It's clearly not an infrared motion sensor, which has no moving parts.

and the zoop goop

No reason that they wouldnt really. Only problem could be radiation but there are ways to protect against that. The sensors can typically measure any combination of acceleration (accelerometer), angular velocity (gyroscope) and magnetic field strength (magnetometer), none of that is specific to Earth or only useful on Earth. It is relatively complex maths that turns those sensor readings into orientation. If you mean would your phones autorotation work in space, then it depends, if your body is in microgravity since it is in freefall, so is your phone and it wouldnt work the way it does on Earth, but if you were accelerating, had artificial gravity or were not in freefall then the auto rotation should work relatively normally.

Maybe your clock is configured with Australian settings.

They skipped all the details but they make a tiny mechanical system that can bend and flex due to acceleration or rotation or magnetic fields, etc. The technology is called MEMS and is used in a lot of devices, from motion sensors, to microphones, to pressure sensors, etc, they are used in a lot of sensing devices.
