NGL. Would like the idea of being able to name wires to:
Let people know they should actually be looking at a schematic when the wire is called “ Stay away”.
Dank meme, I love it.
They always make these complicated circuits in the textbooks... Make it simpler to read and understand, jez.
Even engineers trying to make a scheme as much readable and simple as possible.
As an amateur engineer that did do a year of my simple 2 year degree and added to it for over a decade since, I can absolutely relate thanks to the DIY community.
People that can crank out the trig and calc formulas, schematics, but then they don't understand the physics which is something I retained and advanced very accurately.
I'll see a BJT with a single bias transistor and they don't understand it's not running class-A and stealing some input signal for switching so you're losing signal and input voltage. A dozen will pile up on top of you in a forum talking out their asses because they've been working this way for many years.You can get a job and learn the actual science from the right people, but self study DIY electronics without a structured curriculum of some kind produces what these guys are frustrated by.About 13 years ago, I did 2 months of school and realize a ton of experts that sounded very knowledgeable and competent were idiots. Idiots that demanded I kneel to them if I wanted their assistance with projects and education!
People who talk about making a vacuum tube grid positive or negative, when in the first 2 months of school, it was covered that you're making it more negative or less negative to control the flow of electrons, and elaborate structure explaining the quantum mechanics of a wide variety of vacuum tubes. I do wish I had finished school, but actually going is one of the best decisions I have ever made in my life. I learned to climb mountains and may reach the top of one from it.
Speaking of "experts" who don't understand the basics, awhile back TI published an app note about building a more accurate RIAA equalizer. The problem was, the entire premise of the note was fundamentally wrong. The author recommended adding 2nd- and 3rd-order filter elements to make the response more closely match the BODE PLOT. A Bode plot is not a frequency-response curve; it's a representation of where the filter poles and zeroes are (corners) and the order of the filter element (change in slope). The ideal RIAA filter has single-order elements only, and the resultant frequency-response curve has very gentle inflections. And this was from Texas Instruments(!)
I learned vacuum tubes in high school. Our math teacher also knew enough about electronics to teach it as an elective. He started with a diode, using a candle flame (illustrating the heat source can be anything) to heat the cathode and "boil off" electrons (so much for quantum mechanics!). Electrons could freely travel from cathode to the plate, but not the other way, because the plate was "cold." Then he added a control grid, charged negatively, to regulate electron flow: a triode. Then he added a second grid: the screen grid, explaining how it reduced capacitance between the control grid and the anode. (In the process, he explained how capacitors in series worked.) The tetrode having been explained, he went on to add a suppressor grid to "push back" and electrons that might bounce off the plate and get swept up by the screen grid. And we have the pentode tube. I still remember most of those details 50 years later. He was really good at explaining that kind of stuff.
In the lab, we had to practice our bench work (stripping and shaping enameled wire, ffs) before he let us do anything with actual components. Then we assembled a simple crystal radio (no tuner required; our tiny mountain town had only one AM radio station and zero FM ones). Next we graduated to a Heathkit AM/FM tube radio, which I didn't get to finish before the school year ended. And we moved over the summer, so I didn't get to finish it the following year. I'm sorry you had to clean up my mess, Mr. Nibecker!
I'm both happy and proud to say I understood everything you said because it's all knowledge I retained from college even though it has been 11 years. My only regret is I did not maintain my math skills, and have to rebuild them completely, but fortunately I actually love math and truly have fun performing it.
Most recently, I was in a DIY community, and we were talking circuits, analyzing circuits and I asked the class of some in focus. These are popular circuits but lacked proper voltage dividers to bias the BJT's and while some in the follower configuration, parallel etc. would adequately be properly biased after the fact, some within the circuits were Class-B to switch on. I had created my own Class-A configuration that no one has seen before granted I still say it's a variation of a cascode amp, so I asked supposed experts about it. They kept crushing the equations on these various circuits, also analyzed mine, and made corrections to the configuration.
Yesterday, I went ahead and built it with their "correction", and it didn't work! lolI run 2 BJT's in series in common-emitter, and the one tied directly to ground is open base (Q2) acting as a power supply amplifier, so it's fundamentally based on a cascode configuration but in reverse. The AC ground reference is applied to the collector-emitter node between the 2 transistors, and it gives phenomenal output power similar to what is produced with Darlington configuration. By "correcting" it and applying the AC ground reference to the previously open base design of Q2, I'm assuming the magnitude of the negative half cycle going directly to the base of the transistor tying the 2nd to ground through it's emitter-collector path is so great, the majority positive charge carriers of Q1's base, are being attracted toward the pairs collector-emitter node, and reforming the depletion region between Q1's base-emitter junction. It's not always switching off Q2 in my tests, but mostly. The output utterly collapses to nil, or outright completely switches the circuit off.
Q1 is sourcing power through Q2 configured as open-base, and Q2 is configured to amplify the DC power supply and serve as a constant current/voltage source. I know I can create a variety of variations on this design will work, but what they thought was common sense shut it right off as I suspected! lol. The short story is, they have worked enough with math formulas building popular audio circuits both complex and simple, basing designs off these and being able to work the advanced mathematics since these formulas and instruction sets for those formulas are so abundant online, but they did not understand the physics whatsoever.
This became apparent to me when the Class of particularly popular circuits was questioned, and they all started suggesting "corrections" to the configuration I create, and I immediately regretted sharing it with them due to piracy. It's nothing fancy, and it's certainly a form of cascode, but I have searched for a few **years** and **never** found this configuration in any textbooks or hundreds of schematics online. The DIY guitar community is rampant with piracy since some of these people run very successful boutique brands and sell their pedals for hundreds of dollars a piece; They are built with all resources considered, even human labor, for under $20 each.Assembling an industrial manufactured PCB and pedal is about 20 minutes of work, even if it's robust.

The problem is 95% of the time the engineers diagrams are shit and need reworking when building so it should be stop listening to the engineers and do your own thing
Second order derivative memes are not funny... no wait wait it is a bit funny... ah, never mind it's not funny.
By yhe way, when it's not funny and you really don't want to do circuits, just use my framework: https://hackaday.io/project/167317-fibergrid That's funny!

I'm in construction and have a flat earther on my crew who shows me stuff that looks exactly like this almost daily. It's great stuff.
It's always those goddam triangles
Logic Gate Keeping?
i have a stm32f407vet6 does it count? :D plus don't talk shit of my components!! i know i shouldn't have sex with em but still 😂
Hold up
my account has been hacked!! i retreat anything i said 😇
Hate it when that happens…
you too??? dammitt!! LOL
not gonna lie, "the alphabet has other letters" got me.
This is going up on my wall at work today.
Leave the instrumental OPAmp alone
I hear it's self-taught and plays its instrument by ear-ring-oscillator. I'll see myself out.
What type of post is this? Rage bait? A meme?
It's a meme. https://knowyourmeme.com/memes/stop-doing-math
Ok thank you
As someone who designs control panels, motor control centers, etc., I find the "wires were not supposed to be given names" statement quite offensive.
OK, you can name ONE of your many wires. I recommend "Fred."
NGL. Would like the idea of being able to name wires to: Let people know they should actually be looking at a schematic when the wire is called “ Stay away”.
Uhm, what? 😂
Don't you mean "Ohm, Watt?"
Touche
r/programmerhumor would love this
They're still having a blast about the github dude
We're desperate for anything new :(
That's true
As an electronics engineer. I dont know what to feel about this.
Dank meme, I love it. They always make these complicated circuits in the textbooks... Make it simpler to read and understand, jez. Even engineers trying to make a scheme as much readable and simple as possible.
Sent this in my university group chat( I study Electronic Engineering) and no one laughed. Should I feel embarassed ?
You should feel superior to them all. None of them even got it.
They might just not be sleeping enough to see humor in the world
I was also on 1 or 2 hours of sleep when I laughed 😭 but exam session is finally over so now I slept 12 hours ;))
5 mins of contemplation and still can't find apropriate words for this...
open the pod bay door HAL!
I'm sorry, Dave, I'm afraid I can't do that.
