That shit was easy. But I can't solder shit even if my life depended on it.
it's not difficult but you need good tools
I have good tools. Everything just falls apart in my hands.
I tried to assemble a 1:72 plastic helicopter model once. Never again.
There are no more programmers left just webdevs
soldering is easy if you suck just practise more. And use leaded solder not that lead free crap
cause i don't know how amps are made
Because when we post about it, the threads are deleted and we're told to go to
Well, no one is gong to understand a fake circuit like that.
Because electronics recquire you to put some effort and time in it and programatrannies are all used to speedrun their education with youtube tutorials and more recently ChatGPT
because programmers are there to do programming not electrical engineering
because we don't care, either it runs or it gets replaced. same reason os admins don't give a shit about the hardware platforms their vms run on.
>why don’t mathematicians know anything about building calculators?
it's been almost 15 years at this point so my memories are kinda vague but as someone who started in electrical engineering then switched to comp sci within a year, what I remember having difficulty with is the math. more specifically, I didn't know where to "start" my calculations because everything is just a big interconnected circuit with arrows pointing here and there and every time I thought I got it, when it came to solving new problems I always got confused again. dunno if I was just a brainlet or things weren't explained well.
playing with the breadboard in lab was fun, even though I didn't know shit. I basically forced-paired myself with some Korean kid that didn't speak English (as a matter of fact he never spoke at ALL) but was smart as fuck. he'd solve whatever task we were given in basically 5-10 minutes and I just piggybacked off him lol. Thanks koreanbro, but it was for naught.
Comp sci on the other hand clicked for me right away so I switched as soon as I could. Wasted almost 2 years on this.
I was a programmer for quite a long time until I decided to try my hand at electronics. It really ended up for me at meme Arduino projects. While it was fun at the beginning, more complicated PCB circuits especially designing pcbs and doing all those calculations, even if they seem very simple, completely filtered me. I think to each its own.
Use Kirchhoff's rules to set up a system of equations. Then use matrix algebra to solve for the currents, etc. Time dependent shit adds more complexity though.
There's a lot to learn, it can be quite unintuitive, it's often taught poorly (with bad high-level analogies about water pressure that only serve to mislead and confuse once you drop down a level), and it's usually not a requirement for CS degrees.
I'm interested in electronics but my knowledge has huge gaps and is built on shaky ground.
Interested in any resources targeted at people like me (i.e. I know that a capacitor stores energy and can suppress power supply ripple and/or be used to pass AC but not DC, but I don't know how "charge" relates to voltage/current/power, how to calculate the value I need, or how to judge whether I need to use one).
>how to calculate the value I need, or how to judge whether I need to use one
This is funny because designers dont bother with knowing this stuff either. They go for rule of thumb values that "just works"
Cuz its gay, bunch of dusty dudes hanging out in a dark room touching their wires together trying to turn on a lightbulb. Too bad no amount of connecting wires and batteries is gonna make a pussy wet
What is that?
I don't know what the fuck am I looking at but would this be possible LULZ?
you made jtag as ground, you are literally retarded.
Because programming is simple and brainless with zero penalty for doing it wrong - whereas designing a circuit above trivial complexity requires intelligence and insight, and can come back and haunt you if you get it even slightly wrong.
It's why modern "electronics" is just a cheap uC and battery slapped into a box, no matter how cheap and nasty it's meant to be: programmers are a dime a dozen, and increasingly replaceable by AI.
What's so hard about it? Isn't it just logic gates? Programmers deal with boolean logic all the time.
>Programmers deal with boolean logic all the time.
And fuck it up. This is fine if it's software (fix, recompile, push update), but if you've belted out a million device that doesn't take into account the propogation delays of 74HC chips, well, your customers can't just download 74AHC chips into their devices, now can they?
>isn't it just logic gates?
lmao, you wish
Because they study CS, not ECE.
I did ECE, around 80 percent dropped out, out of which around half went on to do CS. CS is easy as fuck compared to ECE.
>picrel filtering programmers
it doesn't filter programmers. It filters coders.
I felt filtered by electrical fields, maxwells equations for stuff like wifi and radio signals, brutal stuff, signal processing etc
because EE is a harder field where you work 80 hour weeks with AZNs and top out at a lower salary than a fresh grad a FAANG.
i really like it as a hobby though.
my uni deliberately taught it poorly to filter people into other engineering streams.
later on they admitted that they could not educate everyone possible.
then, when the electrical engineers got into jobs, they vented that they were glorified paper pushers anyway.
I believe that. But it's a shame because electronic devices use circuits. And many people use electronic devices.
Because circuits are unintuitive. Programming starts with simple procedural instructions: A, then B, then C. Circuits are interconnected, everything happens at once without delay, every part affects every other part instantaneously, and the math is much more complicated.
But also academia is to blame, particularly for not treating circuits uniformly (input on left, output on right, ground as lowest node) and introducing intuition for when to use what circuit model (why small-signal here, why this hf stub is a short at this frequency, why we use steady-state here etc). Instead, unis give you the equivalent of poorly written webshitter code and the difficulty lies in deciphering the syntax, not understanding the underlying logic.
>Circuits are interconnected, everything happens at once without delay, every part affects every other part instantaneously
Circuits are difficult because the opposite is true and math becomes even more complicated. It's more like
>A, then 1.6 ns later B
>but in the mean time some asshole comes along with E inducing noise in A that messes up B
>now C didn't get right thing and decides it would be fun to mess with everyone and starts talking to itself and starts oscillating like a politician
>in the meantime D starts heating up because C is making it consume power
>D's parameters change inducing positive feedback until breakdown and smoke
>No idea what's going on at this point
>After many moons you learn that there are some sneaky hidden parasitic elements between A and B
>Now you do another analysis with some bloated SI/PI package and extract parasitic elements X, Y, Z
>Back at square one, but compile time is 7-14 days because PCBs take time to manufacture
>C still oscillates
Academia can only do so much. You can only really learn by doing and seeing what works.
>everything happens at once without delay
Nope. In fact this is most of what makes it complicated.
teach me senpai
/gee/ bullies me when I post my pink laptops 🙁
that's so fucking cool. need to see more of that. do you have the display part designed yet?
yeah, I'm using an iPad mini 2/3 retina display with a custom backlight driver pcb. I got stuck trying to edit the orange pi 5's device tree to output edp from the hdmi port. theoretically it's possible, since the pins are muxed on the rk3588s, but I can't figure it out.
I couldn't find a pic of the back of the display assembly, so have this google™ sketchup™ screenshot of the design
That is a very pleasant color combo you've got there, would use in public even especially since it looks so sturdy at the same time.
>orange pi 5
was thinking about getting one of those, from looking online it is indeed possible for similar device but I've yet to find documentation. it has made me interested even more though
Is that keyboard a custom design? and if so why not reuse an old thinkpad keyboard or something
No, it's a mini Bluetooth keyboard from aliexpress that I've decoded the matrix on and wired to a pi pico running qmk. I drilled a hole through it to add the trackpoint
I dont think there's an old thinkpad keyboard small enough, it has to be ~200mm wide to fit with the 7.9" 4:3 display.
I did use a thinkpad x61 keyboard in my other laptop, which had a 10.4" 4:3 display.
https://crafty.moe/pinkpad.htm
forgot to add the pic. you can see the trackpoint module here, as well as the touchpad (which is from a ps4 controller)
>I thought you guys are smart
90% of programmers are braindead CRUD/webshit copypasters
Because they took different classes, you cretinous roll of biological film.
You are going to hear a lot of cope in LULZ about this but the real reason is that doing anything that requires physical strenght will ruin their painted nails.
LULZ is LULZ but better.

Take care of your nails, princess.
i'm autistic, but not autistic enough to waste my time learning this when i'll never use it
only use case is going innawoods and making my own hardware
I'm not a programmer, but still a tech worker. I get filtered every fucking time I try learning this shit, because it's explained in boring and confusing ways in books, and I haven't been able to find an up to date book that teaches it in a PRACTICAL way.
but I really would love to learn. seems really interesting, being able to modify circuits to transform then into something else. like those DVD-to-laser scanner microscope conversions...
it's heresy
I’m an EE. Went into C then C#. So I don’t touch circuits at work anymore. I’d go back to lower level development, but the pay isnt as good.
> op, the bloated and retarded sex offender gets btfo by the entire board
this is the kind of low iq monkey that thinks he's an "engineer" because he loaded up eaglecad to design and print out a circuit board to drive some LEDs and 555 timer.
do u guys also put pics of your wife on your PCBs? picrel, it's my battery management pcb, featuring my wife nitori kawashiro (I love her)
Most programmer's are just criminals in the sense their trying to minimize effort and maximize money. However they're too busy and dumb to be real criminals. The ones that aren't go on to become based hackerzmans.
yeah man, people should do a LOT of effort to, e.g., grow tomatoes and build houses. how do people dare automate shit to concentrate on solving more important problems?
Because it's a totally different topic, so there is no reason to study it unless you are specifically interested in hardware, or because it's a hobby.
You might as well ask why so many mechanics are filtered by playing the drums.
i have long nails
I did my undergrad in computer engineering and work in software today( typical, right?). Dealing with the physical world where uncertainties exist and things are hazy with noise is not at all like developing software in an environment where the CPU and related components guarantee behavior. You also have to actually do math and understand it. CS kids who are ok/bad at math can hunker down and git gud at their theory classes when the time requires.
Personally, I liked the part of my education where I got to work with system verilog and FPGAs as well as breadboard and produce a complex circuit. It's cool to develop a processor and be able to run code on it even if it's just an educational environment. Having the money to drop to learn this stuff is a large barrier to entry. You can buy a laptop and use that to learn CS and many other things.
Tldr it's fundamentally harder to deal with and control uncertainty + accessibility
