  • A hot air station is nice but the biggest help with small electronics is magnification, your hands will be a lot steadier once you see better. I think the control loop in our brain can handle small movement a lot better once the feedback is bigger. Once i see the tip of the iron under the microscope i can solder miniature smd stuff without shaking at all.

    Good tweezers are a must. And a iron with intigrated heaters in the tip like the cheap t12 stations from ebay works a lot better than the stations with tips and heater separated. A nice project is this:
    https://github.com/wagiminator/ATmega-Soldering-Station

    You can get t12 handles and tips for cheap on aliexpress.

    Also the cheap hot air stations are fine but i would check the temps with a thermocouple when setting it up the first time they may not be calibrated correctly.

    Get lead solder, if you wash your hands and dont eat the solder its fine, it will flow better and doesnt need the high temps of unleaded solder.

    Flux also is really important, you can mix your own with rosin and ethanol for cheap but you can only clean it with ethanol so be aware that its very sticky. If you have questions please ask, its always nice if people learn to repair stuff :)


  • Yea you also should have the car your are charging from run while charging yours and while starting so the alternator can help out with the current that is needed and the other batterie does not deplete to much.

    Hell if you have a diesel with no batterie and a gas car with an empty batterie you could still start both by first starting the diesel with a roll start and then charging your batterie from their alternator while its running.





  • I cant even see the goalpost annymore… I dont care if you were in the military or not, what i implied is sad is that you somehow never learned enough about electronics to know that what you wrote is bullshit. Maybe you fixed all the equiptment? But you sure as hell didnt fix it by understanding circuits or electronics if you think 12v can harm you by touching it only because the supply is capable of high apperage (with the source “movies” none the less). “Fixing” stuff is in this day and age also not something that shows you understand how something works. In most industries and i would guess the military it is the same, fixing means “i replace module xy because the error code says so / untill it works”.

    I also dont feel like responding annymore because the next message propably will be another goalpost push on why i dont think you did x or y when it was never about that…


  • if you really judge someone about spelling mistakes and typos on a platform that people use on phones where it is super easy to mistype something well then i cant help you… also why are you calling others child if this is your reaction to what i wrote? You had the most childish reaction i saw on here for a long time.

    With what you wrote i woild bet that anny ee student that passes the first semester has more knowledge than you… and no i am not a student annymore i graduated with a bachelors end of last year :)) Also if if i still were a student that would still make me a lot more qualified than you, because before going to uni i had a 3,5 years apprenticeship as mechatronics technician that made me a “elektrofachkraft” so i am qualified to work with industrial systems up to 1000V.

    If you really worked on all those systems you said you did and dont know the basics about how voltage current and resistance relate to each other it would be very sad…


  • I am an electrical engineer i have touched plenty of 12v and 24v… If movies are you source for eletrical safety then yoi are a idiot…

    Current has nothing to do with that because it doesnt matter that your car battery can supply 100 100000 or 10000GA 12V will not be enough to make a significant current flow through you because your skin and body resistence is way to high… basic like 6 grade physics with current=voltage/resistance (yea i know body is not purly resitive etc but its good enough) whoever said voltage doesnt kill but current does was a idiot… neither does its a combination of a bunch of factors that matter…current voltage time frequency etc…

    I dont even need to write something for point 2 because you have shown to not know basic understanding about dc circuit analysis…wtf

    Rhis is so much bullshit… car batterie wont do shit because

    1. You wont feel 12v at like 60v you maybe start to feel something depending on how you are connected…
    2. You get shocked because the neutral and litteral earth are connected. Not because of reflecting waves…





  • Have you read the first paragraph if the lidnked articel? It quotes the criteria right there: "Extensions must not be AI-generated

    While it is not prohibited to use AI as a learning aid or a development tool (i.e. code completions), extension developers should be able to justify and explain the code they submit, within reason.

    Submissions with large amounts of unnecessary code, inconsistent code style, imaginary API usage, comments serving as LLM prompts, or other indications of AI-generated output will be rejected."

    Maybe instead of commenting under every comment that lines this change read the articlw first? Ai is fine if your code is fine and you uderstand it. If the reviewer has to argue with a llm because the submitter just pasts the text into his llm and then posts the output of said llm back to the reviwer it is a huge waste of time. Thiss doesnt happen if the person submitting the code understands it and made shure that the code is fine.

    Yea that is true but a lot of these questions use the division sign when they should just use a fraction and everything would have been easy to understand. If i see the devision sign and there are more than 2 elements like x=a÷b+5 i cry because if they just used x=a/(b+5) or x=a/b +5 it is just visible no ambiguity. (a/b as in a over b, idk how to do fractions on the phone if you know tell me!)

    Using parenthesis can really help if you want to simplify a term or need to rewrite something. I do that all the time because a lot of times you then can just cross stuff out fast on equations or get a common term that just has some factor instead of having a convolutet equation.
