What is worth desoldering from old electronics? || DIY Fume Extractor 

100% agree

I got a taste of desoldering components and I'm hooked!

I agree, i got 3 organizers filled with parts, and the best thing is that i dont use them that often lol

Some people can't go in a bar, or a casino; I can no longer go to recycling centers.

Кирилл Рагузин It does make me truly sad. Sourcing quality parts when you live overseas is a complete pain in the ass. Don't get me even started on consumer electronics these days.

Кирилл Рагузин God bless Mikhail Gorbachev

Кирилл Рагузин It's easier to buy new part than to salvage old parts. Furthermore what is the chance that you will find enough scrape PWM controller of right type that suit your needs? Personally, I don't have lot of scrape electronics so i have to buy parts. In past i was scraping electronic parts mostly DC motors (never resistors and capacitors) because that was only way to get some parts. I could forget parts like servo motors, step motors, transmiters etc. Now i have eBay where i can buy parts that i would pay 4x - 10x higher overhere. It's not crazy world, it's only economy of situation.

Кирилл Рагузин They are probably like most and don't understand or care they just buy the latest trendy new gadget.

Mat Matej because it keeps your skills sharp and ready that's more of a reason to do it.

lucky b*stard!

Some college kids are just overly spoiled by their rich parents. It's sooo unfair!

I'm not surprised. When I was in college I would dumpster dive at the end of every semester. You will now believe the stuff they throw away. I once found a macbook pro with a bad hard drive. For the price of a hard drive I had a less than one year old macbook.

@@cultclassic999 what else did you salvage from this dump ?

@@laurentl3410 I work at a university and it's totally true, college students throw away plenty of useful things. Mini fridge, microwave ovens, smart phones, scooters, bicycles, laptops, computers, backpacks , clothing and dorm furniture. They waste money like its water. They should clean up what they dont need and sell it or donate it so as not to waste resources and pollute the environment.

That's *EXACTLY* what I was just thinking

Sorry I didn't understand. Why therapeutic ?

Strangely enough, this is what I looked forward to doing on Christmas Eve for a a period in my teens and twenties. My parents would go out for the night socializing and I had the house to myself. Turn up my favourite music albums, get some soft drinks and pull out a stack of boards I'd accumulated for the past year. Most of it still ended up in the garbage years later, but the point was I was doing my thing with no one bugging me. (Oddball!!! LOL)

@@tuxxic For some, the process is relaxing. Speaking for myself, there is a satisfaction in retrieving useful parts from something regarded as junk. The process doesn't require intense effort. You don't have to think very hard. It requires a little attention, but overall it's a stress-free, useful occupation.

I agree. For some reason, it's relaxing and removes stress.

I agree! Electronics recycling can’t recover and reuse things like FR-4, ceramic, silicon, leaded glass, and etc found in electronics. Reuse of components is better. I also heard somewhere that it takes 70 gallons of water to make one IC

You'd be surprised to see how many guys fund throwing electronics away wasteful! 😝 It's best to salvage!!

Finally, im not the only one

Ya bro Mee too 😂

I try fixing first, then salvage, recycle the plastic add the metals to the pile. I separate by type and take to salvage yard about every five years or donate to the Boy Scouts. As for small electronics I will save a few boards just in case you need a small part for a repair, also if you use a hot air station you can remove an IC easily.

I get 99% of my stuff from the side of the road or op shops

great tip!

Hashem Mehyar Thanks

And what if you do both the inlet and exhaust? Or will that just decrease the performance again?

@@yosyp5905 Yeah, that doesn't really help.

Good point about the environment! 👍

Screws are huge and useful everywhere.

@@cultclassic999 no, it isn't. The same time is better spent elsewhere for the same purpose. It's a ridiculous fallacy.

Stephen Low , good idea. I'll do that next time.

Life hack

And if you cut off the connector from the power supply cut the cable in the middle. So you can save the connector (with the rest of the wire) as well :)

@@alexstone691 LOL. I hate that term "hack" as it's used now.

no way!!! that's so cool!

Just use a fabric mask

i made a fume extractor using pieces i salvaged from old PCs lol

I'm exactly the same I collect and desolder old PCBs just because there's something very satisfying about figuring out how some random obscure component with no part number woks There's been some.... Interesting side effects

@@harrcorr216 Meanwhile I repaired my first electronic. I replaced a mosfet and I was very proud.

@@funkblack fixing things is far more rewarding then taking them apart I respect that

Yes

It smells like angry smarties to me 😛

@@blick9538 I can’t rally explain it

Fume extraxter :but not for me

I hate it

QSL

Also it's good to picture the board and store it as your own components database. EXIF stores max 64KB, so you can add to it the characteristics of almost all components!!!

Well a little on the ocd side arnt we now

Hi-5 for 1 upping me I've been using my propane torch which can get a little too spicy for the board. I bet I could dial in my heat gun and be looking like I'm a pro at it.

@@GbpsGbps-vn3jy I wish I had thought of that; excellent tip! This beats digging through stacks of boards to do a random search.

The question is what is you time worth for a 5 cent resistor?

Well, salvaging those components even if they are 5 cents is always good if you have the time

@@San-zi1ig not in the real world of economics. Most people have realities to deal with.

@@larrybud Every hobby is worth your time, is not about the money.

@@MastersPipe Everybody has a finite amount of time, is spending a couple of hours to pull a dollar's worth of parts really worth it, rather than spending that time creating useful stuff?

interesting 😂

Hmmm I don't know if my eyes would like that . . .

i would think that would be hard because solder is shiny...

@@fungusenthusiast8249 Paint it black and use welding goggles.

Electronics, not to be confused with Electrical work. The difference is scale and one is primarily DC and the other AC with some crossover in each. In a nutshell! Lol ...... once you get into it, be prepared to be hooked forever.

videos like this validate my electronics component hoarding. I should not be watching.

I've been doing that forever haha

Pssh. You used a propane torch? I throw it in my fireplace!

What about EXPLOSIVES??

Works amazing for IC’s. Just heat up a row and ply it up with a screwdriver. Repeat for other side.

@Demo but i don't have carbon windows

Doesn't the pet store just have carbon bits, something like Norit?

@@saltysoysauce954 What he means by carbon filter is carbon-impregnated pads, which are used for chemical filtration in most aquariums. They're usually thick enough and might do the job just as good, but some are too spongy to be effective.

@@SartBG Oh interesting, never saw those. Pretty good idea!

They are also used in vacuum cleaner air out..put? You can buy them from stores and they usually are "cut your own" type. Fanned cooker hoods also carry one, they are replaceable parts and in Finland super/hypermarkets sell them too.

you _can_... never... have too many screws i concur

U screwing with me!? XD

CTI go screw yourself ;)))

exscrews me?

***** when did this comment became the place for screwed jokes? =]]

Just use a propane torch on the solder side of the circuit board and they all fall out.

+Crazy Hans Use a bathroom vent fan hook up a dryer hose and vent it outside.

+Patchuchan great kill the human race... very very extremely slowly.

i made myself one of an pc cooler (fan) and an adapter

I smell something and it ain't solder fumes

Yeah, I just have a window fan blowing out a window, away from me.

ALWAYS!

So true! xD It's usually the one you finally decided to part with! ;p

Is it okay to reuse salvaged component I mean, are there any lead poisoning or health issues about it

+patprop74 Thanks mate ;-)

soldering fumes certainly is harmful to our health lol. i kind of like the smell as well.

yes the symptomes you get are like astmha

You can get AIDS from smelling it .............

you will know because your asthma will get worse. Just build or buy a fume extractor for soldering and let fresh air in every 30mins (winter).

That's because there are no lead fumes from soldering. The temperature is nowhere near high enough. The fumes are from the flux, which is a known carcinogen.

My brother made one explode in the lab for science (they took their distance). One piece got stuck in the roof, so yeah, be careful with the big ones.

Ya me too

And there's a method to do a super easy and fast to it's just a propane torch.

even more terrible that people would rather throw stuff away than to donate it to someone who could use it. Hell id be happy if people tossed busted hardware at colleges for learning purposes but no... trash can is the only way the get rid of good hardware.

@@oceanbytez847 Laziness. It's not even legal to toss electronics in the garbage, but people do it anyway.

@@baruchben-david4196 its not legal to do a lot of things that people do daily. kinda like that unspoken thing where everyone always goes 5 mph over which drives me insane bc breaking the rules so easily just gets you in a mindset where other rules lose meaning and are easier to break as well. so essentially speeding on the daily sets you up for careless thinking that can result in bad driving. psych 101 on that mark. If i am known for anything it will be for saying that everything is reached in steps. The taste of black coffee, spiciness, law/ rule breaking, bending your own principles, ect. Starts out small but doing it repeatedly makes doing it again easier and doing something more severe easier. today it is tech in the trash. tomorrow it turns into dumping used oil in your own lawn (just saw someone do that yesterday in fact haha.)

I think mindlessness is a more dangerous slippery slope than breaking the law. I have the utmost respect for safety, order, and effective solutions. But sometimes the law is not that, in which case I will consciously and deliberately break the law, and stand by my actions if called out. IMO the dangerous part of being a scofflaw is not forming a habit of rulebreaking, but forming a habit of thoughtlessness. Every time a group of people I'm with attempts to jaywalk, I will call attention to the specific details of the situation, how close the crosswalk is, how often and how fast the cars are coming, and so on. In order to force the people to be mindful of their actions, and not just break the rules out of careless habit. I don't have a big problem with jaywalking (though i usually don't do it), but I do have a problem with mindlessly jaywalking in a situation where waiting for the crosswalk is a faster and safer solution

^ this is true

joblessalex I was think the same thing LOL.

joblessalex i would say the same!! Ceramic capacitors and small transistors are worth to save... It will make you save kilometers to go to the electronic shop! I save also cables and some connectors. As he said "we never know when we will need it"

yahnsolo I always save the small transistors and ceramic caps. Electrolytic ones go to the trash, but the ceramic ones are definitely worth saving. I use my secret weapon to remove them all quickly. Blowtorch to the back of the circuit board and a pliers or big magnet to gently pull them off. Works every time. XD

+theLuigiFan0007 i also save the ceramic caps ,resistors,transistors and dip chips

***** Indeed. Especially when you find lots of a specific value or high precision or a unusual value you think might be hard to find if you ever need it. I usually can't save the tiny SMDs even though I had a small tweezers for handling them. They just get stuck in a blob of solder. I might try *****'s idea over a white sheet of cardboard once I get my oxyhydrogen torch I use to desolder working again. I need a new clear plastic tank and graphite plates for the hydrolysis.

you can actually do nice things with bare PCB's. I made a phone case from one.

Scavengerx3 You're welcome ;-)

Scavengerx3 j

when a youtube guy is better than ur teacher

+Patchuchan propane torch works well also...

Sometimes the pins are bent over. and you should use a clothespin or something to help grip them to extract them.

DO NOT DO THIS UNLESS YOU HAVE A BOARD OF INDUCTORS OR RESISTORS!!! I used to do this and it heat damages the parts very badly... sadly it is the only way to get BGA chips off of boards though. The fumes are awful too because you are getting burnt board, solder, plastics, and other crud all at once, which is a HORRIBLE thing for your health

@@allurared9029 i dont think a soldering iron is much better, because it takes a lot longer

Hackermaaaan! :)

I think the point is potentially saving these items from landfill or incineration, and the benefit of reuse. Of course that didn't work out in your case though but at least you tried and now, later on, there are places to donate those components to to save them from needlessly being thrown away. Certainly when you first started to collect there might not have been the same places to donate those items to. Globally WEEE is a scandal and we are spending a lot of time and energy taking metal out the ground just to put it back in within a few years in an almost unrecoverable state.

Growing up in the 80s my dad saved everything electronic from the 60s on.. we used all kinds of things. Lots of audio circuits from old radios and stuff like guitar effects pedals, even a safe.. he was an electrical engineer so maybe it's different but I save stuff and use it all the time.. lots of connectors, lamp, voltage regulators, switches and jumper wires.

Once you have more than you'll ever use, you have too many.

@@ionymous6733 Maybe so... But how do you know when you have more than you'll ever use? Having a ton of extra parts may even encourage you to try something you might otherwise not try...

It works if the components have long leads that you can heatsink on the other side.

Yep but the torch idea isn't good actually. Because the components reach a sudden abnormal amount of heat which will degrade the parts? Or cause failure after the heat was applied? Idk desoldering seems to be the best I guess.

put a fan on the other side to cool the components and you'd be fine. most of these components ain't worth it anyway so break a few won't matter and most importantly it save you lots of time. Just check each of them after so you keep the good ones and throw the others.

Yep. Silicon components are more robust than most think, and a hot air paint stripper gun is your friend. After all, the components had to tolerate pre-heat and wave soldering in the first place, and SMD parts need to tolerate reflow temperatures. Regarding donations, This guy sounds like he may be in Europe. Since this video was made, things have changed. Unless you are outside Europe, donating through Patreon is a bad idea since they collect VAT and under normal circumstances it wouldn't be payable. Better off donating via Bitcoin if the channel has a Bitcoin address, or via Paypal. Also, two currency exchanges soaks still more of the donation.
