Circuit boards have always fascinated me. Mainly because I have no clue how they work.
Sure, I can assemble a PC, but that’s really just 3rd party work- plugging that SATA cable into a slot REALLY takes an MIT education!
What I’m trying to get is how a computer, even something as simple as a vex robot, works. I know that capacitors store either a 1 or 0 based on if it contains electricity or not. I don’t get how a GPU interprets those numbers and sends data to a monitor to interpret as light.
So, what I’d like to ask is how certain parts work, how they’re made, and how (if possible) to make them yourself. I know that some of you have made your own bots of of a circuit board and a CPU.
How does a processor work? How do you know how to solder it on a board? What allows it to handle processes? What miniature parts go into it?
How do you array a motherboard? How do you make/get a PCB? How do you know how to align the circuits on the board? Do you need a Mobo printer?
How does a graphic card work? Is it pretty similar to a mini-computer in itself? Is a GPU simply a graphic specific CPU?
How can you possibly make BIOS chips? How do you preload information onto a small chip and know what information you’re putting on it? Does another PC make it? How was the first PC’s made?
How does flash memory/RAM work? Is it again nanoscopic capacitors being charged or uncharged to represent bits?
I know these are pretty intense circuitry questions. My knowledge of circuitry is limited to wiring a bulb into parallel with another, I barely know anything.
I don’t believe the PC builder deserves respect. I believe the person who made the motherboard, who made the graphics card, deserves respect. I believe the person who actually made the GPU or CPU in that mobo/graphics card deserves the UTMOST respect.
Any references, wether in print or on the net, are appreciated. I want to be guided into the direction of circuitry and how it actually works, rather than just using the “3rd party” end of putting a card into a slot. The fact that a PC works is an absolute phenomenon.
