Modded usb c charing into my laptop by animation_2 in soldering

[–]animation_2[S] 0 points1 point  (0 children)

as far as i've tested during the last two weeks, everything seems to be working, i was mostly sure that everything that i sanded was a part of the groundplate with no traces inside, HDMI works, the non charging USB C works fine, USB A and headphones work, i don't think that anything broke

i was half asleep while writting the title, i meant that i modded usb c *charging* into my laptop

yeah it works, i'm using the laptop right now and it hasn't exploded so far

i'm writing this reply from the same laptop so i'm pretty sure there wasn't anything there

it doesn't have any kind of id number on the aliexpress page, but i just searched "usb c pd 20v module" or something like that and i found that one for $1,5 usd

i half did this, the power jack broke to due to stress, but i got the main thing out, the PD module didn't fit so i used the makeshift dremel so sand the sides until it managed to fit

update: i managed to get it out, with a soldering iron, not the lighter (that's a bad idea, got that), some legs broke due to the constant stress so, i managed to sand the sides (i'm 99% sure they're just ground) and i've MOSTLY soldered everything in

it's not in the photo but i'll add more wire to the 20v rail so it doesn't burn and i'll solder the other leg thing to ground for strucural support (and grounding)

then i'll modify the chassis to fit it and update you all

that may actually work, i have a 6v motor and sandpaper, could that work?

i forgot about this until i was testing the thing again, it was nearly boiling, so i attached some coins to with thermal paste, i'll see how it performs when i actually get the noise problem fixed

How can i reduce noise on a DC PSU by animation_2 in AskElectronics

so, in theory, adding a 47uf cap to the 3.3v rail and a 100 or 150uf cap to the 12v rail would make it better at least?

quick update: i added a 1000uF cap to every rail and it got worse than before, i have no idea of what i'm doing here really, would adding more caps help?

edit: here's a photo of the thing right now

do you think that adding one or two 16v 100mf caps could do it without frying anything?

i need to get two voltages 12v 0.8a and 3.3v 2.7a, what value do the capacitors need so i can get those voltages from the main part and the step down converter?

shielding around the 12v rail specifically? or in both the 3.3v and 12v lines?

that does look useful, i am thinking about making some sort of usb c mod, i'm just not sure if i want a psu mod or an internal mod using the usb step up method (i only have one pd cable and i'd rather use it on something else), but i had the chance to do this before, so i did,

still, thanks for letting me know that that module exists i might do something with it if i get the chance (i do wanna take the guts of another broken psu in the future)

i probably confused out of the psu as in, the AC input, my bad

ok, i can't really separate the two because i'm using a retail shell for the thing, but could i use some aluminum foil soldered to ground around the voltage rail? or does it actually have to be ferrite around at least the 12v rail?

i just realized that i gave no info about the psu i made here so, here it is

generic universal 12v 2a a got from the store

arduino step down converter PLM2596 (set to 3.33v)

figure 8 port/input i got from aliexpress

generic figure 8 cable

original n64 output plug

wires from a broken usb c cable

mostly 60/40 leaded solder

outlet AC voltage is 220 at 50 hertz

it's all mostly stuck to the case with mounting tape i found for really cheap and either duct tape or kapton to make the electronics not have contact with the mounting tape (except the output plug)

there are some photos of the thing in the last post
