this right here is something quite a few people who do a lot of soldering never use
some irons actually tell you to not use them
EG those Hakko stylus tips
but there's other stuff like some tips are just weak to a lot of flux or you may have nicked it
either way, unless you're using fancy Hakko tips most are pertty cheap. My most expensive Goot tip was maybe 1,200JPY (like $12)
I'd go for a Hakko station but I don't do nearly enough precision work to warrant it
AliExpress has 10packs of tips for $3
probly crap but i could afford to replace them every day 😄
well, it all depends on what you're soldering too
if you're doing surface mount and stuff like that then you should actually use a good iron and tip
but pretty much anything else and a $6 tip should last you a good year or more
I have a client trying to weasel out of a bill and I saw it a fucking mile a way. I put a stop on an addition to the order because I knew if it went any further he'd just drop off the face of the earth
im mostly practicing on cheap craft circuits and old PCBs. I probly wont try to solder onto a fresh board until i get better
if i had a nice station i might find a way to ruin it 😄
I bought a multimeter and one of the first things I learned was using it incorrectly can break it
once you get into it get a good multimeter. I've got a fluke I've been using for... like 20 years now 😄

I have 3 things to say about soldering. Fuck non lead solder, fuck flux, and inhale all the fumes you can, it makes the experience less painful.
i am exactly the kind of faggot to buy non-lead solder
JIK is that plain steel wool? or something similar?
one guy on youtube suggest nothing besides paper towels and retinning
well i hate soldering, so i probly wont do it often enough to get lead poisoning 🙂

Here's the chip I burned out on my board, the L293DD Motor Drive IC
https://www.arduino.cc/documents/datasheets/H-bridge_motor_driver.PDF
@M4Gunner Just do what I did and burn out all three NAND gates in the middle of the class exam.
If I'm not wrong, it looks like it can't take power above 7v max. So likely was burnt out by connecting 2 18650 batteries in series, which gives up to 7.4v
@meratrix that would be sweet, then they could show me what i did wrong faster
what kinda hardware?
Now, I still have to confirm whether this IC is suitable to power 2 12v motors at all
Seems legit, however I'm reading some posts that say if you give the L293D about ~6v, the voltage drop is high enough you may see barely 3v of actual power, with the rest being wasted on overheating the living shit out of the chip. People suggest other driver chips for this. Havent confirmed for the DD yet

these ICs can actually be stacked in parallel, though my Driver board only had one on it
Hello Comp Sci, I'm a sw engineer CS degree new to this discord. I'll be lurking here.
Looks like yall talk a lot more about electrical eng.
if anyone needs assistance in the discrete math realm that's my jam.
Nice to stalk ya.
just what we need, another lurker <:pepe_eyes:378719408362881024>

By day I work for an ISP/Telecom using PHP in the whole stack range to do a thousand things.
But my work history is in QA.
By night i'm working on designing a minecraft server plugin that lets you build zelda-style dungeons.
