I'm a postgrad student now, so still living through coffee-fuelled nights of deadlines and self-loathing. But yes, this was incredibly calming and lulled me to sleep and I didn't have nightmares about exams 😄😁
I love learning “about” physics. I like videos from physicists where they explain things, but even basic physics with applied equations just murders me..
i remember i took physics 102 electricity and magnetism expecting to do circuit design or electronics, ended up being basically a copy of physics 101 but with electric and magnetic fields/forces.
Could you possibly do an video on the animal and plant cells. Maybe get a model and do a little sketching whilst explaining what each organelle within it does. I think that would be neat, thanks for the great content. 👍🏻
Request: Can you ever do a video on nanotechnology, futurism, “the singularity”? Especially nanotechnology though in general would be awesome to hear you talk about!
Anyone just have their mind explode when they think about the fact that we don’t “create” electricity, and all we actually do is use magnets to move electrons in a wire that are already there. The biggest power plants in the world are just spinning giant magnets around a wire. It’s insane.
Same applies to everything else in nature. We take elements and compounds and reshape them into new forms. And we ourselves are the products of countless natural processes synergistically shaping those same elements, each cycle adding new layers until single cell organisms formed into us. We are both results of the process and the process itself at the same time.
Same! Glad I'm not the only one. Fell asleep tp some ASMR a while back and woke up to crinkling. Grumpily turned off my phone because it was so irritating
Love this video. I repair electronics and I would love to see more and more people being less afraid of it, and start getting hands on. Another interesting point about diodes is the fact that because the voltage drop is relatively stable across a diode (although not completely) it makes them useful for a lot of functions. If you reduce the current flowing through a diode, by a factor of say 10 by changing the value of a resistor, the voltage drop across the diode will deviate by only a small amount.
Just finished the video and just realised you actually mentioned this. When thinking about a diode as a resistance It helps to imagine that actually it is equivalent to a variable resistor. The magnitude of the current dictates it's equivalent resistance. This becomes useful when using transistors. I'm getting super nerdy I know.
ok that makes sense. clearly i never had a good grasp on transistor technology. its hard to understand how current is controlled with current and how it causes such huge gain increases
@@LetsFindOut1 It's easier to think about it in these terms. The small base to emitter current that "switches on" the transistor simply allows a larger current to flow the collector through the transistor and out of the emitter. Current flowing out of the base region allows carriers to flow from E to B. So when a voltage is applied across the BE junction, which is roughly in the region of 0.7V, a small number of carriers flowing from the emitter combine with the minority carriers in the base, and the rest flow to the collector.The usefulness of equivalent resistances for transistors is really useful when doing small signal models where you want to simulate impedance and small signal gain of an amplifier etc. The subject is quite heavy to discuss in RU-vid comments and I find it hard to describe. Think I need to study it all over again.
I remember watching this video before going to college to study electrical engineering. I just got a job offer at a major semiconductor company. Thats for the inspiration.
6:10 I don't think I've ever known or heard about grease being on membrane contact pads. That's really interesting and I don't think I've ever seen that in a device but does make sense. Especially on devices that may be exposed to moisture or other harsh conditions. That's why the fingers are usually gold-plated. Usually with a tougher hard plating instead of a standard soft gold plating like you would see elsewhere on circuit boards. The hard plating helps hold up over time.. like what you would regularly see on an edge connector, cartridge, or something else that has to stand up to repeated action and wear. I have seen Greece on gold switch pads. Like if you open up a multimeter and look at the Gold fingers under the main rotating selector knob.. sometimes they'll have a really light coating of conductive grease. But for the most part unless the meter is used in a bad environment and needs to be weatherproof... High in meters of void grease because it can attract more dirt and debris which will wear out the contacts quicker. Obviously it would cause wear quicker than just a press of a button because it's being rubbed back and forth on the gold plating. But I've only ever seen that in test equipment meant to be used in harsh conditions, or in multimeters that aren't quite top of the line not really cheap stuff or anything but just not your top end fluke or HP agilent meters. It seems a lot of the cheaper meter movements may use it to help the smoothness of the mechanism whereas the more expensive meters are smooth because of the high quality. Both are fine in my book and I've had dozens of meter spanning the spectrum from cheap too metrology grade But concerning the membrane pads.. I usually just see the rubber/ membrane button with a black conductive rubberized coating so that when it is depressed.. it will bridge the little fingers on those membrane pads Go back and check out one of "marco reps" video when he was restoring the fluke calibration unit. I think that's the video maybe it was one of his high-end meter restorations I'm not quite sure. But he took isopropyl alcohol and started cleaning those pad contacts.. and it wiped them away and he ended up having to design and replace the board. He tried conductive paint at first to try and touch it up but ended up just making a custom board. Pretty interesting and a really useful thing to keep in mind if you do a lot of equipment and metrology type restoration and libration work In his example I think the conductive/carbon graphite type coding where the actual board pads themselves. Hence why they wiped away with solvent when he was trying to clean them
Oof You are epic I just love your way of ASMR not just random obnoxious noises maybe it's me but I prefer people like phonecian sailor or emphermial rift rather than people recording random tapping noises what you talk about is actually interesting and also *EDUCATIONAL* P.S you literally are the fastest growing ASMR channel
On that note, archeologists recently found an ancient city in turkey (can’t remember the name rn) that is dated to around 11,000 BCE, and even though it’s only been 10% excavated, it’s so much more advanced compared to anything at that time, and might be evidence of older advanced civilizations. Super cool stuff!
I sincerely feel you should have more subscribers. Your most viewed vid has half a million subs yet people don't think about subscribing. Love your channel, it's a great balance of education and asmr.
Didn't think I was sleepy... Seven minutes in and I'm struggling to keep my eyes open! You truly make amazing ASMR. (This brought me back to high school science class. Far-fetched request: What about some simple biology experiments/fun?)
i literally despised AP physics one in high school, but i always liked to draw the little circuit schematics. hoping that gen physics will be better a second time around because it's required for my degree
It represents a diode, which is just a one way valve, basically (current can only flow in one direction through it). An LED is a light-emitting diode, which is a diode with special chemicals that react with current to produce light.
yea the power supply was really whining if thats what you mean. (if not maybe its just the yeti mic im using) but thanks for the kind words rub. i appreciate the support
Hey LFO! I wanted to give a positive suggestion that I believe you’d be interested in. I believe it would be good if you came up with a 30-45 second spiel describing what your channel is about to new viewers. It’ll give them insight to the norm and your passion so they feel like they know you a little better and feel like they’re thought about. It’s good to do instead of just jumping right into it. Even though you’re probably always excited to jump into the topic of the video :)
Let's Find Out ASMR You’re welcome! You might notice that the bigger ASMR (and other YT channels) do that! As you’re growing to be a larger RU-vidr, you’ll want to implement some of these techniques! Love ya brother.
Do you study these subjects before you make videos? Or have you just studied your entire life? Judging by the vocabulary you use on various topics you're either above average IQ or have a great memory. The depth of knowledge helps a lot to make the video both relaxing and interesting. Thanks!!
i certainly studied this at one point. theres no way id be able to learn even this smll amount just for a video. but thanks forgiving me the benefit of the doubt lisandra
If I purchased the necessary parts, could you assemble a Raspberry Pi machine of some kind? I wouldn't care what the function would be. Dealer's choice!
Admittedly my knowledge of the subject matter in this video is limited, but I feel like quite a few of the things you said were wrong or at least not entirely true. I could be wrong about that, but going through an electronics book could make a good book video!
