  @lcamtuf this is a Homer-Simpson-Causes-a-core-melt-in-a-simulator-that-didn't-even-originally-contain-fissible-material scenario, isn't it?    @lcamtuf Nothing to see here. Move along.       @lcamtuf@infosec.exchange Soldering, or forging?    @lcamtuf ah, you set it to brazing, that's slightly hotter than soldering  @lcamtuf@infosec.exchange you're holding it on the wrong end /s :neofox_solder_googly:  @lcamtuf I had that exact thing happen on the same type of station not once but twice. One had a shorted output mosfet, the other I didn't bother debugging and instead replaced the station with something less crappy. I also found out that this comprehensively fucks the coating on the tip, so the tip needs replacing too if you repair the station.  @lcamtuf if you want to solder that hot, you're also going to need a barrier gas feed   @qbi "Wir sind Handwerker. Wir können das. Das Handwerk.  Holy shit! @343max sorry i assumed you are a german speaking person.. @343max oida won i mit dia weaniarsich red und du mi mit deine deitschen hirnwindungan ned vastehst, donn tuats ma lad.  Update: As @343max pointed out, the photo is a fake. It was never used as an official photo in an ad campaign.   @lcamtuf specialist here, this is not funny!   @lcamtuf yes, once it starts to melt you can use it to attach components (that’s why you always should have multiple tips, they get used up over time). /s   @lcamtuf@infosec.exchange yes. and make sure to hold it like this neocat here :neocat_solder_googly:  @lcamtuf Glowing 1000 degreee soldering iron vs the sanity of the fediverse     @bluestarultor @lcamtuf it says "Error" right there and it sure looks like it's having an error to me so I guess yeah that's normal, nowt to worry about  @ifixcoinops it also says 0% which I guess is output power PID setpoint. Something's wrong. But this little thing should not be able to deliver the power required to reach a red hot temperature anyway. If this is indeed an internal short, it should trip all sorts of fuses, RCDs, etc. So maybe this is simply just a Dall-E image? @bluestarultor @lcamtuf @otte_homan @ifixcoinops @bluestarultor Hmm yes, looks like there's a gang of DALL-E forgers trying to sully the good name of a $38 soldering station from AliExpress @lcamtuf @otte_homan @bluestarultor I mean if summat fails short rather than open then you're gonna have a day y'know These things don't have variable output, they go RIGHT HOT AS WE CAN LADS until the computer tells it stop hotting @ifixcoinops @lcamtuf @otte_homan @bluestarultor The surprising thing to me is that the internal current carriers can handle enough power to heat a soldering iron tip orange-hot without instantly dissociating into smoke. Usually these things are made out of gossamer and fairy wings (cheap, factory-farmed fairies, obviously) and have a safety margin of -10% or so. @whbboyd @lcamtuf @otte_homan @bluestarultor Well they can't, that's why they melted into a lump capable of passing a lot of current but no longer capable of saying That's Enough Current Thanks  @lcamtuf@infosec.exchange it's normal for it to say error when there's something wrong, yes   @lcamtuf Yes, that's totally normal. Your modern soldering iron has a built-in working light to help you better see the components evaporate. It's also perfect for night soldering!   @lcamtuf    @lcamtuf Everything's   @lcamtuf maybe a decimal error, and it tried for 1500 °C (but only getting to 1000 °C, judging by the orange glow)              @whitequark@mastodon.social @lcamtuf@infosec.exchange "The feedback loop is open!" Famous EE last words.   @lcamtuf I had this happen on a TS100 and they made me take pictures so they could send a new one under the warranty   @devkitsune    @lcamtuf I don't have a soldering iron, but I do know they're supposed to get pretty hot to work, so I think this is perfectly normal(???) 😁 /s   @lcamtuf Yeah! The KSGER units have a setting enabled by default that can cause the unit to lock up. If it does this while the PWM cycle is on, it'll just keep heating the element until thermonuclear fusion occurs. No, I don't remember what the setting is. :(   @drwho Almost hot enough to start a Honda Scrambler on the first kick. Maybe. My uncle found his in the burned out remains of my dad's garage after the Northridge quake and it still was too cold to start.    @lcamtuf This advanced version lights up the handle in a nice red color so you know how to hold it properly            @lcamtuf  "It's your father's lightsaber. This is the weapon of a Jedi Knight. Not as clumsy or as random as a blaster, but an elegant weapon for a more civilized age." @lcamtuf This is how hot my high school robotics team thinks a soldering iron should be used at. Always. @MarkAtMicrochip @lcamtuf well it does illuminate the solder joint, so you can see better. They have my sympathies – waterpipe solder really makes it hard to make these joints look good.  @MarkAtMicrochip @lcamtuf "the solder isn't melting properly, better turn up the heat some more" is always the hardest habit to break for newbies @gsuberland @MarkAtMicrochip @lcamtuf recently helped at an extracurricular "soldering for EE and related programs university freshladies and -gentledorks" workshop organized by two student clubs. 40 people who never soldered before, LED christmas tree with THT LEDs, SMD transistors and a TSOT MCU. They honestly did amazingly well. I didn't understand how well they did until I was asked by one of them who was having trouble: their tip simply transferred maybe half the heat, and of course … @funkylab @MarkAtMicrochip @lcamtuf I think I'd have gone with "flux tends to work better if it's in the solder instead of in your nostrils" @gsuberland @MarkAtMicrochip @lcamtuf … still was oxidized enough to make it hard to have a nice solder coat. |
@lcamtuf you w0t m8?
