When extending thin pairs of wires like these I like to stagger the joins, so cut one wire 50mm or so shorter than the other so even if the heatshrink moves or wears through, the solder joints won't easily touch
Watching this in New Brunswick, Canada on February 10, 2021 and it is -2 F out, so no cooling fans needed today. Always a joy watching your videos, I will be warmed vicariously. Ride em, Cowboy!
Make sure to follow me on Instagram for daily updates and little pieces of art instagram.com/the_post_apocalyptic_inventor/ (Also one correction concerning the video: The computer fans are "axial" not "radial". I simply misspoke there.)
Great simple project. When lengthening cables I prefer to stagger the joins slightly (so they are not on top of each other) then when you add the final outer heat shrink it’s not so bulky looking in the one place. On low voltage you don’t even have to heat shrink the individual cables if you stagger them enough.
A bout 5 years ago, I also made an ultra quiet, single fan unit. I reverse flow mounted the fan with blade guards on top of the AC transformer to extract solder fumes from my PCB work area. I could not afford one of those fancy fume extractors. So for less than $8 bucks, problem solved.
I liked this project and associated video. Great up cycling! It's also very sweet of you to go to the trouble of making this fan for your hospitalised landlord - I hope it gives him some relief from the hot weather and his operation and recovery go well.
This is actually one of my more favorite projects you've done in a long time. I think it's because it fits well with the name "The Post Apocalyptic Inventor" given the circumstances to which it was made.
Great minds think alike... I have an *very old* 120vac computer muffin fan that I gave to my mom & she just loves it. She has it on her headboard and its sturdy... she tends to knock over and break any tabletop oscillating fan she has so this never breaks. It's very quiet and I oil it up from time to time. It's been the only one that lasts.
Interesting that you mention Tucson Arizona. It's where I live, and right now we're in monsoon season with high temperatures and periodic high humidity. The last week in July I measured outside air temperatures of 44.4C on my back porch in the shade. My solution to the heat is air conditioning and ceiling fans.
Hello From Austin, TX... Thank you for your great videos, I am a newbie at electronics and although only a few things are over my head... most things are exactly what I need to learn. Your style answers all the questions I am usually left with in other videos.. Again, thanks!
Nicely done. You could also fit a flat foam charcoal impregnated filter on the inlet side and use the thing to filter and blow away soldering fumes from your workbench. Adding a variable DC control would give you some speed control as well.
I look forward to new video even though I really don't understand all the science behind electricity. I know how you feel about the heat wave in Germany. Here in Texas we have just cooled down from temps that were above 41C (101F - 107F) for almost 2 weeks. We will have a week of mild temps next week....relative term I guess......33C - 37C (90F - 98F) I work Midnight shift so I'm out of the higher temps that happen during the day. Keep those "simple" videos coming as they do represent projects we do most at home.
Simple but heartfelt project to help your landlord out. Very nice thing to do. I don't mind smaller projects, while I do learn a lot from the more involved ones, sometimes a simple but clever project, especially one with some theory behind it, is just fine as well. Keep cool!
great mini project ! - can i suggest another? its mainly poped up because ours died a death and its repair is beyond me at this time. The challenge would be for a electric fence energizer. from what i understand its a pcb board (with pulse times etc controlled on it) a capacitor to hold from 1-10 joules and then some other bitsnbobs.
Great Job, Gerolf. I love the "american accent" lol! The fan turned out great. Greetings from Georgia, in the United States. It was 96 F with 80% humidity where I live.
I'm using a pair of silent PC fans in summer. Much nicer than a regular household fan. And for the stand I used a spring clamp camera/flash holder. All the making was to do the mechanical adapter to connect all the parts and the electrical adapter to connect to power supply. No parts were modified - everything can be reused after disassembling.
Sometimes the simplest projects can be the most inspirational. Your videos have helped inspire me to go about buying and fixing old machines or consumer electronics like transistor radios and old angle-pose lamps. I've got an old General Electric fan that needs some TLC as an upcoming project as well. Thanks for the excellent content!
One thing you could do to make the fan better in the long term would be to make it servo controlled by remote control. I realise that in this case, speed was the most important factor, but in the long term you could make it better. Have fun with your projects, Joe (First time viewer and subscriber)
Such an original idea , the repurposing of the components was quite simple yet so brilliant , as they say simplicity is brilliance , good work my friend.
My computer desk lamp base, busted. So I needed an new base. I stacked two old dead computer hard drives on top of each other, and screwed them together. That became the new base. The base is solid and thus won't be breaking any time soon. Job done. I also have a foldable shopping cart in which I installed corrugated plastic side and bottom panels. But the foldable side panels had a tendency to fall inward. So I glued on to them the powerful magnets that came from the two dead hard drives. They hold the side panels open. Job done. The main wheels of the foldable shopping cart had worn out, so I replaced them with good but cheap lawnmower wheels. However, these new wheels had a 0.50" diameter nylon hub", while the shopping cart wheel shafts were 0.30". But not to worry, I had just replaced some old kitchen and bathroom faucet brass seats. The old brass seats had a 0.30" internal diameter, and the external side had a threaded diameter of just over 0.50". So I just screwed 2 of these brass seats into the axle hole of each wheel, one on each side. Bingo, each wheel now had 0.30" axle hold diameter, just as needed. Job done.
This it crazy, but my friend and I are thinking of riding from Germany to Greece on a electrically assisted recumbent trikes. The crazy part is we are both in our 60's, live in Australia and have heart conditions.Our wallets too are relatively thin(so we don't bother with switches either :) ...any information or projects on electric bikes, trikes, travelling through Germany on a bike, camping etc. will mean a lot to us. We are planning to camp much of the way, so it should be fun and very challenging...no, we are not planning to die.
That's a lovely gesture, I've just had 3 days in Frankfurt, so I've experienced your summer first hand. I hope your landlord feels better. It's been stupidly hot at home in the UK too, and I might have a few 120mm fans cabled tied into blocks ;-) BTW, when you've got the label off to remove the tacho wire, it's worth giving them a drop of oil on the shaft. Oh, and one last thing, in my experience, PC fans always blow towards the label side. They often have a mark on the outer case moulding too with an arrow.
Suggestion for future improvement: Cut the angle piece in the middle so you can tilt each fan on its own and add a speed controller. The Heat is killing me and we only got to 35°C at my house(outside, in my room i had 28°C max today). Fortunately i have to work tomorrow (climate controlled workspace!!!)
Even better, replace the clamp on those universal gooseneck mobile phone holders with the fan, and combine two of them into one! Now you can clamp it anywhere, direct the fans freely where you want, and you end up with have a unique-looking piece for not much money in parts!
Need more power? Use server fans! Some of those smaller fans looked like they might have been the stronger type with blades that have a steeper incline to them. Still, very good idea, I should do this myself with some of the many old monitor stands I have sitting around!
I did a similar thing and I use a cheep triac voltage regulator to control the voltage into my old fashion transformer based psu 12v 1A, and it eats up that triac chopped voltage, just perfect. Nice build
Nice little project and a good cause too, it's been hot here in the UK too, but not THAT hot, so fans have been pretty popular sale items, just glad I have a couple of them in my bedroom!! :P
Ive done this before and putting the fans side by side is nice, but if you want to really move some air you have to put them in a row...I had 4 fans strapped together and that sucker could really move some air.
awesome video! these little projects are cool they give other ideas on how to do the job. i did an even simpler version of this using JUST the fan and a PSU and the accompanying barrel connect from a fried USB3 hub. never thought of using the stand off busted LCD stands!!!
im from south carolina, the southern accent was close, but needs some work, and we dont talk quite like that but you were close on that as well, although most of us just speak regular english.
no dude! remember to K.I.S.S keep it simple! instead use a variable/universal voltage power brick (with voltage slider 1.5V DC up to 12V DC ) to control speed of fan.
It was that hot about a month ago over here in eastern Canada, apparently it crossed the ocean :P The only thing on the news here about the heat wave in Europe is that there is one, that there's fires in Greece, and a beer shortage in Germany lol
Some of the power supplies should have had switches if they were nicer ones. Would have loved to see how you would integrate a switch like that in the build.
I liked it a lot. I think some smaller projects are very good so that viewers with less experience can also have a go at making some projects after seeing yours. Another option would be to do a several small projects that are linked together but are stand-alone so that you could stop at any point and still have something that works. For example take this fan, you can add two more on top making it a bit bigger. You could add in a small Arduino or 555 PWM controller for adjusting the speed, another week you could make it controllable wirelessly. What do you think? I am personally very very interested in building a cargo bike and eBikes too. Maybe a series on making a cargo bike and then converting it to an electric cargo bike would be good as a longer term project series. Another option might be to buy ones of those mega cheap engines used to convert bicycles off eBay???
This was a great small project to see. I just did something exactly like this recently also. Although I probably overcomplicated it by designing and 3D printing case.
BTW cool electric cargo bike! I just got an electric bike that I am trying to find cargo solutions for, also. The cargo rack built into it is so wide that normal sets of dual baskets won't fit over it and its about now I wish I had a welder to cut them and add some middle pieces to make it wide enough to fit proper. I was out zipping along in it by three lakes so long yesterday evening that I think I am catching a bit of a cold from the breeze. Fun, though.
Tell your landlord that your subscribers say get well soon
Thanks bud. I will do that!
... I'm in on this one!
I second that.
(and I sport a 12 V fan alike in my a/c-less car, mounted on a goose-necked suction cup, the latter a residue of an unrepairable nav system ...)
Amen ❤🙏
Ampere on transformer@@manfredschmalbach9023
I think it's a great idea with this fan, thank you for sharing your story. Glad to see small project also
mount one under your desk m8, saves you from(madding) long summer computer sessions
Please send 5.8 million of these to Denmark.. we are in dire straits here as well...
Allan Ø.N.
Come to India or Arabia then... and your straits will be straightened out !!!
bpanther ok - i have been to places like Egypt, Namibia, and also India (different parts of) ... what strikes me is that different climates (different humidity levels) is perceived very different. In India i I didn’t experience serious sun burning of the skin for instance like in very dry climates like the namib desert for instance.. our caucasian skin doesn’t seem to like the high UV levels. but you are absolutely right - in India you are very much indeed also needing fans :-)
Send 1.3 billion .... :-)
Nice project, great use of salvaged parts, and elegant design.
When extending thin pairs of wires like these I like to stagger the joins, so cut one wire 50mm or so shorter than the other so even if the heatshrink moves or wears through, the solder joints won't easily touch
And the bulge doesn't get as thick.
@@jerome1lm that's what she said
Watching this in New Brunswick, Canada on February 10, 2021 and it is -2 F out, so no cooling fans needed today. Always a joy watching your videos, I will be warmed vicariously. Ride em, Cowboy!

Great simple project.

On low voltage you don’t even have to heat shrink the individual cables if you stagger them enough.
Wonderful build for your landlord! You’re a good man! Yes please make more of the simple build videos.
I hope your landlord is doing better. If you turn the fans around this would make a good solder fume extractor.
A bout 5 years ago, I also made an ultra quiet, single fan unit. I reverse flow mounted the fan with blade guards on top of the AC transformer to extract solder fumes from my PCB work area. I could not afford one of those fancy fume extractors. So for less than $8 bucks, problem solved.
Dear Sir,
A very original & noble entreprise; I am sure your landlord will appreciate it greatly especially at this time. Kind regards.
I liked this project and associated video. Great up cycling!
It's also very sweet of you to go to the trouble of making this fan for your hospitalised landlord - I hope it gives him some relief from the hot weather and his operation and recovery go well.
This is actually one of my more favorite projects you've done in a long time. I think it's because it fits well with the name "The Post Apocalyptic Inventor" given the circumstances to which it was made.

I very much liked that hint toward reusing the monitor stand and the *all you minimum* right angle channel.

Great project for a great cause! I hope your landlord gets the care that he needs. Love your videos!
You are the most successful ambassador for Germany 🇩🇪.
Nicely done. You could also fit a flat foam charcoal impregnated filter on the inlet side and use the thing to filter and blow away soldering fumes from your workbench. Adding a variable DC control would give you some speed control as well.
Great video! Doesn't matter how small the build is, as long as you solve problems. Inventors and engineers solve problems for people
Didn't you rent an underground vault? That must been quite cool right now. What happened to it?
Thats a neat context for why you needed to make the fan. Best wishes to your landlord. Stay cool.
I look forward to new video even though I really don't understand all the science behind electricity. I know how you feel about the heat wave in Germany.

Awesome and very generous of you. But you could have used a switch from one of those old power supplies that you opened up :)
Nice clean design, I like it a lot. An electric cargo bike sounds interesting.
Nothing trivial about helping an old man who needs it, esp if hes yr landlord. Great job!!
great mini project ! - can i suggest another? its mainly poped up because ours died a death and its repair is beyond me at this time.

Good for you helping him out with a little salvaging creating a much needed cooling device in this weather. 🌞

I've got an old General Electric fan that needs some TLC as an upcoming project as well. Thanks for the excellent content!
You can add Carbon filter and use this to soldering! Great idea with LCD stand.
Thanks for the "quickie" and a big get-well-soon to your landlord
The simple projects are great sprinkled in with the ambitious ones.
I love seeing old bits of junk get turned into practical devices!
Could you please make a smoke purifier/extractor for a soldering iron?
Would love to see your idea on that in action!
Just buy a hepa filter, put it in a box together with some pre-filter and connect a vacuum cleaner to it.
One thing you could do to make the fan better in the long term would be to make it servo controlled by remote control. I realise that in this case, speed was the most important factor, but in the long term you could make it better.
Have fun with your projects,
Joe (First time viewer and subscriber)
Weekly videos sound neat, same with that bike.
Nice , good project too to help someone out it was very hot this summer , how can someone thumb down a good deed ??
That's really good, reverse the flow and add a carbon filter and you have a solder fume extractor :)
Your serotonin levels pointing at tons .. happy happy happy
Very nice good idea to build an older person whos sick in the hospital a small fan to make them mor le comfortable
Very elegant solution! Surprised you don't have a bucket of salvaged toggle switches lol
Such an original idea , the repurposing of the components was quite simple yet so brilliant , as they say simplicity is brilliance , good work my friend.

I really like the small project I think you should do more of them.
Get that fan to that old man. 99F is hot anywhere. Stay cool.
I love the simple build. I'm going to do this today.
Ya pretty cool try it and make video ok
It's not about giving simple idea a chance. It's about helping fellow human being with it. Instant like. :)
What a great idea and such a nice thing to do.
That's a lovely gesture, I've just had 3 days in Frankfurt, so I've experienced your summer first hand. I hope your landlord feels better.

Nice use of that old monitor stand!
I love it, gonna build it for my fishroom and as a carry on for when i am walking between class on uni here in South Africa
not trivial. these excellent fans are often simply thrown away. this video inspired me
Me, I throw them in a box. Now I have to look around for a bit of aluminum angle and some kind of a stand...
Need more power? Use server fans! Some of those smaller fans looked like they might have been the stronger type with blades that have a steeper incline to them. Still, very good idea, I should do this myself with some of the many old monitor stands I have sitting around!
Videos like this make me wish TH-cam allowed multiple up-votes or a LOVE option rather than just like.
I did a similar thing and I use a cheep triac voltage regulator to control the voltage into my old fashion transformer based psu 12v 1A, and it eats up that triac chopped voltage, just perfect.
Nice build
Nice little project and a good cause too, it's been hot here in the UK too, but not THAT hot, so fans have been pretty popular sale items, just glad I have a couple of them in my bedroom!! :P
Ive done this before and putting the fans side by side is nice, but if you want to really move some air you have to put them in a row...I had 4 fans strapped together and that sucker could really move some air.
0:10 why not make the fan double or triple ended?
I like your cargo bike and good idea the LCD stand.
Hey Massi, nice to see you here, I hope you guys in Italy don't die from the heat as well, but I guess you're probably used to it :D
The Post Apocalyptic Inventor Yes, in this period it is very hot. It would take your fun. :)
Plant more trees = Less Heat
4:38 There are arrows on the fan pointing the direction of the airflow.
awesome video! these little projects are cool they give other ideas on how to do the job. i did an even simpler version of this using JUST the fan and a PSU and the accompanying barrel connect from a fried USB3 hub. never thought of using the stand off busted LCD stands!!!
Looks cool, love your channel... Hope the landlord gets better...
As a southerner from Texas, your southern accent needs a LOT of work.
:D of course it does. You guys will have to teach me whenever I make it to your parts ;)
The Post Apocalyptic Inventor , absolutely. It'll be fun
I think it sounds just ridiculous enough to be friggen hilarious! :) Don't change it!
Besides, let me hear your German accent... boy! =P
im from south carolina, the southern accent was close, but needs some work, and we dont talk quite like that but you were close on that as well, although most of us just speak regular english.
you could add a dc-dc converter for adjustable speed!
no dude! remember to K.I.S.S keep it simple! instead use a variable/universal voltage power brick (with voltage slider 1.5V DC up to 12V DC ) to control speed of fan.
you could even put another row of fans on top of that, so you get a square setup.
Aspall. Good man. They might do tours of the place.
It was that hot about a month ago over here in eastern Canada, apparently it crossed the ocean :P
The only thing on the news here about the heat wave in Europe is that there is one, that there's fires in Greece, and a beer shortage in Germany lol
If it's not to humid there y'all should make evaporative air coolers, they are cheap to build and work great.
Some of the power supplies should have had switches if they were nicer ones. Would have loved to see how you would integrate a switch like that in the build.
rubber at places to cut down on vibration
Cool i use those same type of fans to cool my solar charge controller and rv bathroom skylight vent nice job!
Digging your specular component!!!
Please make a video like you used to. Those were well made and a pleasure to watch. Where has your intro and precise, well edited style gone?
These simpler stuff is very nice. It can be up to us to make improvements and personal modification. Looks really cool! ;)
Why not have a small filter behind it with the cheap thermal gel? So it would cool the air even more.
I would have placed a drop of sewing machine oil in the fan bearings when you had the label off to cut the blue wire.
You can use that idea, to make an exhaust fan, for your soldering bench!
-2 Celsius right now where I’m at, and loving it haha!
I liked it a lot. I think some smaller projects are very good so that viewers with less experience can also have a go at making some projects after seeing yours. Another option would be to do a several small projects that are linked together but are stand-alone so that you could stop at any point and still have something that works. For example take this fan, you can add two more on top making it a bit bigger. You could add in a small Arduino or 555 PWM controller for adjusting the speed, another week you could make it controllable wirelessly. What do you think?

Greetings from Argentina, here we are "enjoying" about 6º C.
Will the electrical safety Dept at the hospital have to check your fan for leakage current?
I found you from Ave, I love a nice practical build to help a guy out. Weesles!
What about adding a motorized pan and tilt mechanism?
Great mini project.
This was a great small project to see. I just did something exactly like this recently also. Although I probably overcomplicated it by designing and 3D printing case.
Crude rude and effective but not scrap switch laying around?
You should see my improvised window ac unit that i brought back to life using an 87 jeep blower motor and an electric fan off a chevy truck
I like these simple hack-it-together projects. Makes me think. Love the hillbilly american accent.
What a great video. educational ,entertaining, and funny great job love to see more like this.
I like it great useful little project.
Love the smaller stuff very much
I hope your Landlord Gets well Soon!
BTW cool electric cargo bike! I just got an electric bike that I am trying to find cargo solutions for, also. The cargo rack built into it is so wide that normal sets of dual baskets won't fit over it and its about now I wish I had a welder to cut them and add some middle pieces to make it wide enough to fit proper.
I was out zipping along in it by three lakes so long yesterday evening that I think I am catching a bit of a cold from the breeze. Fun, though.
