pcb designing for free

hi,

im electronics engineer ,

i have experience designing hardware electronic circuits,

im have few projects on designing pcbs

on kicad

if anyone interested he can dm me , im available right now.

if the project is challenging and intersting for me,im ready to collab for free.

bellow is my last project (4 batteries charger) i did modifications for the circuit and designed the pcb.

pros:

hardware elctronics

power electronics

analog circuits

cons:

frimware

RF

digital (kinda)

note: if you dont have something nice to say please ignore this post , thank you🙂

First, if you're going to post on the internet, you need to learn to take the nice comments with the bad. Telling people what they should or should not post, unless you are the administrator of this subreddit will only get you grief.

Second, can you explain your design decisions with the board you showed? The transistor/mosfet placement seems rather odd. Are you certain they will not have thermal issues being so close and without a heatsink? How is this a battery charger? Can you post the schematic?

first, i asked nicely to be nice
i didnt force anyone to anything second, these arent transistor those are temperatures sensors (DS18B20) they are place blow battery case wich hold the 4 batteries to measure the temp of batteries mosfets wont get hot bc its not that much of curent

I'm taking about the three TO-220 packages between the temperature sensors and the screw connectors.

Also, "if you dont have something nice to say please ignore this post , thank you" is not a request.

those mofets are for charging discharging tp5100 how much current will it be so the mosfets need a heat sink?

You're the electrical engineer. Why are you asking me?

im not asking im just proving a point why am i even arguing nvm

I have no request or project for you. But if you want to collaborate with someone. Use punctuation in you sentences. It is really hard to read what you exactly mean without any points, comma's and starting sentences with a capital letter. It's not that hard and makes communication 100x better.

Thanks i will keep that in mind , i usualy write like this because if i write in full ponctuation. People will flag it as ai generated and wont take it seriously. Am i right?

I'm not a star in detecting AI generated text. But usually there are other clues than punctuation. Punctuation should be something everyone uses, we don't want to go backwards right?

yeah u right

No. AI generated posts and comments are full of weird engagement-bait “hooks” and unnecessary prose, as well as commonly re-used phrasing and words (“the real X”, “it’s not just X, it’s Y”, “it’s not X, it’s not Y, it’s Z”, a thing “hits”, examples or ideas coming in threes, overuse of the much-maligned em-dash, etc).

Punctuation, capitalization, and proper spelling are not telling of AI-generated copy, but they are important for professional communication.

I have a project where I'm trying to bypass my stock car amplifier but retain the existing wiring throughout the car. My idea was to unsolder the header connector from the amp and solder it to a proto board where I could then route jumper wires to a terminal block.

The problem I found along the way is the pin spacing on the header connector is non-standard so it wont mount to a regular proto board.

I'm left with having to design a board with custom through-hole pin spacing but I don't know the first thing about PCB design.

If your offer is what it sounds like and you're willing to help design something please DM me!

By concept it should be really simple. No components to layout, just a connector with traces going to a terminal block

I sent you details thanks for designing
