Ever since I've taken computer engineering 1 and 2, I can't unsee references to it in every day life.
Like on YouTube, one of the buttons on a video (the "next video" one) looks like the circuit symbol for a semiconductor diode.

Nice, there's even a schematic for the input protection and scaling circuit.
How the fuck do transistors even work? How does a program - that eventually gets translated into binary/machine code - even cause these transistors to "do" something?
Apologies for my retardation.
>>54866021
Transistors literally do the job of switching between 0 and 1 (low and high voltage).

Transistors are just digital switches.

>>54866021
Transistors are unruly beasts. They work in complicated ways, so to harness their power, we use different models that simplify their behavior depending on what we want to use them for.
The simplest model is the "switch model" >>54866051 and >>54866069 are talking about, often used in digital electronics. However they are much, much more than that.
>>54866154
.............as dismissive as it might have sounded, he has a point. It's literally why Semiconductor physics is a whole course (infact a whole discipline) unto itself, so there is only so much that he could tell you in that course (assuming it was said semiconductor physics class)

>>54866021
A program is just a sequence of ON/OFF during a period of time that open or close transistors' valve.
>>54866126
thats a regulator.
Transistors are not simply switches, that is incredibly misinformed. They in fact have many uses, they have a built in "current" gain that comes from the doping of either electrons, or holes, depending on the transistor type. They however are not always a linear device, you have to drive them into a linear region in order to use them for amplification, this is called the saturation region. However there are also two other regions that are useful, cutoff, and triode. Really they are fascinating devices but as far as a digital switch goes, FET's are much better as using CMOS tech you can get something that is incredibly power efficient. Simply because of how they work, its either on, or its off. Current flows, or it does not. FET's and transistors can be used to make all the logic gates that are used in creating a digital logic circuit.
>>54866335
People have already noted that ITT.
>>54866335
I should also mention that FET's also have a current gain, and that Vaccum tubes are a type of FET, however they are incredibly power hungry compared to integrated FET's. Therefore FET's can also be used for amplification as the general principal behind amplifying a signal involves amplifying the current.
>>54866311
no its not. its a power mosfet.
>>54866379
Yes but they didnt explain what else they could do, and they also didnt give out some keywords that others could use to further research and understand they way they work and expand upon their knowledge base.

I hope you don't teach for a living
So essentially, a set network of circuits are already present on a CPU and programs are just certain lines being activated at certain times, like gas travelling through specific pipes.
My question is, why doesn't the manufacturer just manually power up all possible lines of circuit and let it sit there and evolve into god?
>>54866431
Fuck im retarded, I have been drinking.
>>54866436
God no, its much worse, I build weapons systems.
>>54866446
............................what you're describing there is much closer to FPGAs than General purpose CPUs
>>54866021
there is a positive and negative side and a third side perpendicular to the two. Electrons flow freely from negative to positive, then electricity is sent through third side cause the electrons to stop moving.

>>54866021
people who tell you that transistor are On/Off switches are partly wrong
yes, thats one use, but transistor are also used for amplification, analog or digital.
they can be used as logic gates
the most used types of transistors are MOSFET and BJT
BJT works with current, and MOSFET works with Voltage.
there are also two kinds of BJTs, which are PNP and NPN, the configuration of each BJT transistor varies, not all BJTs are equal, you must calculate the current that passes trough the transistor to activate/deactivate it. to calculate it you use a Beta that the manufacturer gives you.
meanwhile MOSFETS only require a voltage entry in the gate to activate/deactivate the transistor
if I'm wrong please tell me

My Circuits I prof made it really simple by telling us to visualize a large & flexible rubber membrane completely blocking the flow inside a water pipe. Any pressure (voltage) applied to the water will move the membrane only so far before it either ruptures (popped capacitors are always fun) or the rubber band resists enough to block water flow. Applying pressure in the other direction will return the rubber to normal only momentarily before it too reaches the extreme in the other direction; This is essentially how capacitors work and how they are essentially shorts to AC.
For the inductor, he challenged us to imagine a heavy, stationary turbine fan inside another water pipe which can be made to rotate by simply applying pressure on the water and having the flowing water rotate the fan. Given a constant pressure, the fan will eventually reach and maintain a constant rotational speed, effectively applying no resistance to the water flow. Remove the pressure source and it's easy to visualize that given the momentum of the fan, it'll continue to pump the water around before it finally dies down to friction (resistance).
Put them both in the same pipe and once you turn off the pressure source, you'll see them pushing back and forth on each other for some time(Harmonic Oscillator) before friction brings it all to a halt.

>>54866571
Yeah I went to school with a guy who was doing work on that for NASA, its was pretty cool stuff.
>>54867116
I know that now, but Im recounting a point in time at which my understanding of Inductors and Capacitors was a very inhumanly abstract "V = L*(dI/dT) and I = C*(dV/dT)" respectively. It was one thing to know the equations, it was something else entirely to finally have a reliable and accurate mental image of it's behavior.
>>54867194
Personally, I think It's better to know those equations in the q = C*v and Lambda = L*i form when trying to understand capacitors/inductors.
One stores energy as charge, the other as flux. Simple as that.

Soldering SMD by hand is easier than THT, and you can do it basically with the same equipment as with through-hole. The problem is with de-soldering, as you need hot air gun.

Since noone has really told you this basic thing Im gonna give you this hint.
1 > power
0 > no power
And thats how they work.
Imagine this "or" gate. Power flows through wire A and no power through the second wire (B). (making it "1" on the "A" and "0" on the "B" wire).
1 or 0 = 1 meaning:
On the Q wire, power flows meaning that it "translated" a logical "1 0" into "1".
