Schematics Gen

where do you find schematics? after digging my nose around preparing a library for general-purpose schematics I may encounter, i'm starting to realize this modern internet isn't the matrix i was promised. i figured that when the time came i would just search for stuff and it would pop up, that that is generally not the case, as many schematics are either not easily indexed or are behind a shady paywall. anyone more seasoned know where to look? the thread on the tail end of this board that died for this thread was about appliance repair, it could've been a good thread if schematics were posted; we could start there and move out, but let's draw up the schemas for every possible thing we may encounter, toasters, cars, planes, lawnmowers, tractors, microchips, w/e.

people like to keep them secret when they find them

I'm probably spoiled w/r/t schematics, the majority of electronics I screw with are audio / musicial things. depends on what you're looking for specifically.

I only have schematics for few Thinkpad computers. That's because they are the easiest to find. Everything else is either behind a paywall or obscure russian forums. Probably because appliance repairmen are the modern day illuminati who like keeping their source of income untapped.

>>5753 I am pretty sure that it is the companies making the products that aren't releasing schematics.

>>5758 Schematics, firmware, debug utilities are always released to official repair centers, otherwise how would they perform repairs? Some voluminous appliances like washing machines and dryers came with a schematic printout clipped on the inside, a repair technician could access one when he disassembled the unit. I discovered this by accident myself when I changed the belts on my washing machine from 1993. Even Apple schematics are somewhere online, jewnigger from youtube talked about it. They are leaked, smuggled (Andrew Huang wrote about phenomenon of gongkai, the unofficial free share culture in China, or just any place without defined copyright law) and archived by communities, but these communities are extremely secret. That one Russian forum lain referred to is probably https://remont-aud.net/ , they require you to pass a test on knowledge of schematics in order to sign up, never share files with outside world and contribute yourself. Most household appliances are really dead simple on the inside, and have interchangeable components, it doesn't matter whether a stove costs 200 or 2000 Euro, on the inside it will have same spark generator, same valves and sparks. Moreover, they often share body parts between different brands in same form factor in a way different auto brands share and reuse body parts. Exact replacement parts like knobs and buttons become hard to find at reasonable prices after N years though.

>>5759 Well, induction cooktops are bloody complex on the inside. And aside from the usual "it's the caps!" in electronics repair there is a lot more too it. The real art it repairing it without the schems... Comes down to experience, intuition, ability to guess / trace out parts of the circuit, knowledge. Usual joke is when you fox smth complicated out: "Will propably never get a broken one with the same fault".

>>5770 Also, for the linux-apt lains: A lot of appliances (like smart tv's) run linux on the inside. And there often is a 3-4 pin connection on the pcb with a 3.3V uart signal. Where you can listen to the device boot and spill it's guts about the problem it might be having. That out of the way, nobody said the error message would be helpfull. Or that knowing the firmware flash chip died like an old usb-stick would help in reviving the darn thing. But one part of a lot of modern smart tv's that lends itself to re-purposing is the integrated wifi and bt modules. Quite often attached by usb, only difference is they are powered by 3.3 not 5v. And they show a different vid/pid. But looking up the chip name and "echo'ing" the vid/pid into new_id on the linux driver for it... make fine wlan cards for raspberrys and stuff - fast ones too.

>>5759 With modern electronics, there are plenty of companies with official repair centers that don't actually repair anything, but just replace big expensive modules and throw the old ones away.

alright, so like... manuals, people...

>>5783 doep, mega drive. thank.

I heard at some point the Soviet Union included schematics with electronics so they could be more easily repaired.

>>5783 Where did you find these PDFs?
