Understanding Abstraction is Very Helpful in Electronics and Computing

День тому

Around the beginning of a new year, I usually choose a topic that is related to the channel and universal enough to be interesting for everybody’s life. Today, it is the topic of “abstraction” and its influence on our electronics projects. Understanding this topic also helps you decide on the next steps in your career.

It’s amazing what a hobbyist has access to in 2024. I started out in the electronic engineering profession in the 80’s. Then switched to working in software for 25 years and I did very little hobby electronics. Now in 2024 and I’m really getting back into it. I have all sorts of levels of computing available. Also the tools available would be mind bending for a 1980’s engineer. I have a 4 channel scope that can perform all sorts of magic and it really didn’t cost that much. When I first started out I had little access to books and the occasional electronics magazine. Now we have huge amounts of information available and excellent UKposts channels such as this one. Thank you for all you do. P.s I still like revising my knowledge of transistors

@AndreasSpiess 3 місяці тому

I totally agree (and would add a Vector Network Analyzer or Spectrum Analyzer to the Oscilloscope). You can keep the transisor rung, as we are old and should be able to work on several rungs ;-)

I really liked your video. The next comments are somewhat disjointed. But, they represent my reaction to new technology. I am finding that there is so much new stuff, I feel overwhelmed. So I stick to earlier rungs on the abstraction ladder because it feels more like home. In order to understand things like IQ modulation and beam forming, I have to go to lower rungs in order to understand the math involved. So, what drives me in electronics and science. It is learning and understanding what makes things work and tinkering. I am also attracted to doing complicated things with simple technology. At age 74, I am breaking out of my comfort zone and I am tackling subjects I stayed away from such as math. I find that I have a hard time understanding abstract subjects because my mind can't follow the explanations or lack of explanations about a subject. I am worried about being dependent on what others have done in order to accomplish a project and not learning the basics. I found your video thought provoking and I appreciate what you have done.

@AndreasSpiess 3 місяці тому

Being interested in IQ streams and beam forming at the age of 74 is exceptional! Congratulations. With each abstraction come also new words for sometimes similar things. This is what makes it hard to understand (at least for me). Just one thing about dependence. This is why I am happy to "stand on the shoulders of giants". Nicer looking apples come to my reach this way, not only "low haning fruits" ;-)

ECL for me is a good example for "the ladder". When CMOS chips came, our computers were much slower than the (watercooled) ECL machines and some people laughed at them.

Happy New Year to you Andreas and to everyone else! Just wanted to say that at the beginning of the covid lockdowns your videos (and those of a few other well known "youtubers") inspired me to finally take on a hobby that I wanted to get into for a few good years, so I am very thankful to everybody who created this type of videos on YT, regardless of the "rung" they addressed. In my case, by picking up this hobby I actually went *down* the "ladder" you mentioned. (Is this a sign I'm getting old? :) ) It wasn't profitable at all in the financial sense (quite the contrary in fact!) but at times it was very satisfying. And yes, at other times it was also very frustrating :) But if you try harder you (may) get there in the end :) Thanks again and may you be healthy and energetic for many more years to come!

This video describes the abstraction layers really good. I'm working on an Open source project that is about reusing Old ePaper price labels of shops. Most of the new people join are mostly just want a display to display information from home assistant or other systems, and that is fine. But if you dive in, the project has 2 ESP firmware(S3 and C6), firmware for multiple different MCUs(ZBS, NRF...), a lot of frontend work, a CI pipeline, a HA integration, web flasher... And it fun to dive in deeper but also to just use the project to create useful displays.

@AndreasSpiess 3 місяці тому

Indeed, your project is a good example to show how users and creators work on different levels of abstraction.

@McTroyd 3 місяці тому

Love this concept. It occurs to me that abstraction is also helpful where "the ladder" isn't known by anyone. It's the mechanism that enables fictional stories to work, which can inspire great creations as people explore the rungs going down. For example, consider every time Jean-Luc Picard bellows "Engage!" and his helmsman hits the button on the _Enterprise_ console during _Star Trek: The Next Generation._ Nobody needs to be an aerospace expert to know that lots of things must be happening along with that button push. _Enterprise_ would need to de-orbit, avoiding any nearby obstacles, change its heading, go through the steps to initialize the warp drive, start the warp drive, and monitor the whole process as it transitions to subspace in the event something goes seriously wrong (as it sometimes does). Even with that explanation, I'm only descending maybe one or two rungs on the ladder (as you present it), and it's not likely you'd get much more detail out of Gene Roddenberry's production team. If they knew how to build a warp drive, they probably wouldn't have been spending their time writing stories with it. But, those stories serve to inspire such people as Dr. Miguel Aclubierre to figure out how warp drive might be possible, working "up" the ladder from work done by Albert Einstein on relativity. This is the kind of work that made cellular phones and UKposts possible. Perhaps we may also see warp drive from it, one day. 👍

Thank you for your time an effort! I wish you and your family a Happy New Year! What you explained, I would call encapsulation of complexity. In my opinion, abstraction has more to do with understanding theories e.g. maths, physics, chemistry, electronics etc. Btw, I avoid or skip channels with background music and visual effects, driven by general journalists without a solid MINT background but presenting "sensations" (subjunctives) of science or technology.

Congratulations on your success, you came a long way from 10k subscribers when I joined the channel. As someone who is 100% software oriented professionally and only do electronics at hobby level, the same thing is true for software, however it is important to understand that a lot of times we are talking about different tools with different limitations. Abstractions introduce limitations by their design and in specific cases this is not acceptable. We still are using widely low-level languages like C in the industry, and these kind of languages will never go away. I think same can be said about electronics. I designed some simple electronics for a project where we needed to integrate with a RS-232 interface from a smartphone. In that case using a microcontroller with BT capabilities was the best approach, as the cost per unit was very low, using a RPI or something higher-level would not make much sense in that case, even if creating an integration is times more easier.

@AndreasSpiess 3 місяці тому

I agree: Dealing with exceptions is extremely important. What I learned during my career as an "SAP consultant" whos work was standardization and automation is that people love to talk about exceptions (this is where they see their highest value). I always had a "bin" for exceptions on the table. So we did not forget them, but still were able to talk about the "standard" cases. If exceptions were only 5%, it was acceptable and they could be managed manually (because we were able to automate the other 95%). If they were much more, standardization was not yet done properly and needed rework... Without this bin, the attention to exceptions was way too high...

@siberx4 3 місяці тому

Abstraction is deeply underappreciated. It is the very mechanism by which our modern world is able to build such complex technology successfully. Having understanding of the underlying layers is still important because an abstraction necessarily hides details about the lower layers, but you can't efficiently reason about how to make an SPI bus work between two ICs if you're constantly hung up on the first principles of how diffusion current moves through the individual transistors in your chip. You can only keep so much in your head at once, so you need to be able to look at the problem at whichever layer is appropriate for the work you're currently doing. We always need some number of people working at the lower layers, but individuals can specialize at various abstraction levels and collaborate to produce successful systems and solutions without anybody needing to be a master of all parts. I guarantee that the guy who designs the hydraulic pistons in your car's brake calipers knows absolutely nothing about designing an effective infotainment system or how to tune suspension, but working together they're all able to produce a fully working vehicle.

We play a lot with hobby-level topics and maybe interesting to take a look of what would it take to make i.e. a redundant home assistant that a single hardware failure can't take down and remains online during maintenance or RF comms for which most-times taking down a single gateway disables the whole system. Even at power-supply level it is an interesting topic for expert-level audience.

@AndreasSpiess 3 місяці тому

An interestic topic. I also looked at clusters (as a DEC employee we already had them in 1984). But from a reliability point of view, my finding was that the root cause for most of my (today's) problems was not of technical nature (for years, I did not have a dead HW) but of human nature because of not understanding complexity or simply lack of thorough testing. Adding redundancy adds a whole layer of complexity and testing. When I see all these Kubernetes videos I never see a project with a real value other than playing around with new tech. They preobably have no time for a "real" project because their infrastructure takes a lot of time. So I am not the right guy for such a video. I would not sound convincing. But maybe a video for the turn of the year 2025 ;-) How I handle the issue? I have alarming watchdogs that send me a telegram message if something is not working. Then I can fix it... And regular snapshots and backups, of course. I remember the time when I played with raid disk systems. I lost much more data because of technical issues (maybe also not mastering the technology) than because of HW failure...

Happy 2024 Andreas. Hope you get a lot of connections and integrations this year. I am also from the old school and learned electronics with transistors, integrated circuits TTL, CMOS and even a little bit of valve tubes.

Thanks a lot! Wow, 97.3% male! So here is, exposed in plain sight, the known issue with females not interested in electronics or, more generally, STEM. (My best wishes to the 2.6% female viewers who defy the stereotype!) "Lack of flexibility" (time-wise) is frequently invoked as a reason for the lower female participation, I just don't see how that would be the case on UKposts, I'm sure there are many YT channels where the viewers are overwhelmingly female. If you could get as many female viewers as the male ones you'd be close to a million subscribers! Food for thought! :)

I did not know Proxmox is available on the Pi. 8GB RAM would be too limiting for me (my old thin client PC is limited to 16GB which is sometimes a problem). But I will definitivaly try it.

@muemey 3 місяці тому

I was educated with books like Tietze/Schenk: Halbleiter-Schaltungstechnik, published in the early 1970 years, or Horowitz/Hill: The art of electronics. I am still familiar with these low level skills. The first progarmming was on a Zuse Z23 in a verz basic assembler language called "Freiburger Code". Over the years I made many steps on the ladder you described. But it often helps me, that the lower rungs on my personal ladder are not broken.

@AndreasSpiess 3 місяці тому

We have the advantage of age. I assume it was different when you started with your career and you had to set priorities on what to learn first...

@777swampie 3 місяці тому

A very good market history synopsis! Too many times I'm not eager for a new rung because the business people thinks that their new widget's value is automatically obvious. You made a highly relevant point about the brains limit on each rung of innovation. What happens when the rungs come too fast? One of the early problems with packaged software was that young people could get an answer that was physically ridiculous and they didn't have enough under the hood knowledge to catch the mistake. As always your videos are top quality and very well done.

@AndreasSpiess 3 місяці тому

If the rungs come too fast, maybe there is only a small distance between them and history will forget about them ;-)

I'm in the first row! Soldering is actually a big part of my pleasure in the electronics hobby. I like doing a PCB layout, then soldering components on the board. I like construction. Simply plugging black-box modules together that are then stuck in a box with Velcro or hot-glue, then downloading all the software from some website to make it work just doesn't appeal to me. I don't learn very much. It's fine for working at a job. But as a hobby it's just not satisfying.

@ulwur 3 місяці тому

It's the same with many hobbies and areas of interest. It's rewarding to make some stuff yourself! Just ask any woodworker or hobby machinist. Or for that any painter, crochet maker, seamstress, or any other creative skill. Everything out there can be bought ready made in some form, but without the satisfaction of creating something

@AndreasSpiess 3 місяці тому

I agree with both of you. The hobby should not be the same as the job. When efficiency is important in the job, fun is important for the hobby. Of course it is ideal when the job also is fun ;-)

The "know the rung below being optional" is a point I at least somewhat disagree ... especially in the professional area. I'm always amazed when supposed "experts" in IT that operate networked systems are oblivious about even the most general knowledge of how Ethernet works ... and through that, are completely unable to do even basic trouble shooting ... (which, in a way, is good, because it causes job stability for me ;) )

@AndreasSpiess 3 місяці тому

I take this as my competitive advantage, I troubleshoot all technical things in our family ;-) Learning more than one rung takes time, so it is impossible for young people. They have to focus if they want to become good at one thing.

@cleberam 3 місяці тому

Embracing the innovation and leveraging the possibilities is certainly a must, no denial on that. But two things to highlight, your success and my long-term engagement with this channel came from doing what wasn't done before, and the lower levels enable that; the second thing is efficiency and scalability, because knowing radio waves, power consumption, memory allocation, even how to deal with chip specific funcions and much more on the basis, is the only way to reach cost-effective with scalability and reliability; you teach us that. I'm sorry for the ones who see their projects and good ideas getting stuck because of the lack of deep understanding.

@AndreasSpiess 3 місяці тому

I can tell you a secret: I do not have a deep understanding of most of the things I do on this channel, because I do not have the time to learn it (look at the many topics covered in the 450 videos). But I have my methods to dig deep in some areas where it is needed to get to the overall success. And, as I said, I have a few friends who help me when I am overhelmed with details. Because I have a goal in mind, I can pose questions... As I wrote in other comments: Knowing a lot is better than knowing only a little. But what if you are young and have to do decisions on what to learn? Or in my case, when my video has to be out next Sunday and I only have a few days or even hours?
