This weeks video is going to come out a bit late, sorry guys!

A search on how to convert a fridge showed me this video. The level of detail, and the demonstrated level of competency at working with tubing were my first clue that this wasn't going to be useful to me. And to top it off, at the end our guide says that (despite showing one in the thumbnail) he doesn't have a vacuum gauge, but he's ordered one that should arrive "soon", with the promise that he'll put the measured results in the description. But here it is _6 years later_ and there's nothing to tell us how successful he was - or wasn't. Shows how much he cares...

To help with the soldering (I used to work in HVAC). Clean the end of the tube then apply some flux to the end of the tube. You have to use MAPP gas because propane wont burn hot enough. The solder should melt when it touches the copper pipe and be drawn into the heat. Solder like to move towards the heat. Hope this helps, fun videos as always

Hey bud, I'm am A/C and refrigeration technician, first of all the compressor can go down to less than 500 microns or around 25 inhg. Secondly those compressors require oil in the Freon flow and Freon flow to lubricate and cool the compressor. running it the way you are is not very reliable and is going to have very short life.

I find your channel entertaining! Good job on keeping me around months now! i'm still waiting for your version of the laser razor. also thank you for doing these videos

A video about a >big< musical teslacoil would be great :D

You can do this with a normal air compressor as well. The one I used can easily vacuum down to boil off water. You can also use the refrigerator pumps as an air compressor in a pinch but the normal fridge ones are very low volume (slow) The other trouble with the refrigerator pumps is they easily overheat, and eventually sieze for the lack of oil even when the heat issue is avoided by only using it with short on cycles. These are so low volume that any vac forming has to be very small indeed.

I work hvac and I've always been interested in how these work. Great video

You're a cool dude. You know that? You remind me a lot of my younger brother. I started him off with electronics and computers but he was the one to follow it into an computer engineering degree. I couldn't keep up with the tech and my hands just became too unsteady for such work. Long story short: Good stuff, man. Keep up the good work.

I always wonder why you only have like 108k subs. Your videos are very professional and you have a great style and very cool ideas. Keep the good vids coming!

I used to build custom refrigeration systems, so I have experience at this. Soldering copper tubing generally needs acid flux and preferably, silver solder, working on clean metal. When sanding the stubs of tubing, turn the unit on its side if necessary, more than 90-degree turn even, so the grit will not go down the tubing into the compressor. Or plug the tubing with a rolled up bit of paper towel, to be removed after sanding. Just be careful not to dislodge the temporary plugs while sanding! _For better vacuum, especially for deep vacuum, pump _*_into_*_ vacuum!_ (Deep vacuum is always good, but especially needed for vacuum tubes.) For instance: Run 2 old compressors in series, with the outlet of one into the inlet of the other. If one has larger capacity than the other, you would generally want to put it on the low-pressure side, for maximum pumping rate, but valving varies and some valves require more pressure to open than others. The one with least valve restriction at low pressure should be the one connected to the system being pumped down. Also, a proper vacuum pump can be boosted with a crap pump like a single old compressor, IF the proper pump has a vacuum fitting on the outlet. Another way to go is to pre-evacuate a large cylinder and attach it to your pump outlet after it has pumped what it can out to atmosphere. You also can increase pumping speed --and protect your pump from water damage-- by using a makeshift cryopump; that is, pumping through a U-shaped section of larger tubing you have prepared for the purpose of dunking in ice water with salt poured over the ice. Salt over ice makes the briny solution temperature drop to near zero Fahrenheit, so it can condense some water vapor even in vacuum. Better still, submerge the makeshift cryopump in a container of dry ice and alcohol, or if you can get it, use LN2 (liquid nitrogen). Copper wool (or brass wool or stainless-steel wool) inside your makeshift cryopump will improve the performance by adding a large surface area on which the pumped molecules can slow, contract, and even solidify. Purging the whole system with *very dry CO2* will allow you to turn a crude vacuum into a high vacuum if the cryopump is chilled with LN2, because the CO2 will solidify on contact with such low-temperature surfaces. Other gas molecules being carried along by the CO2 will get buried and trapped in the dry ice formed in the LN2-cooled cryopump. Normal refrigerants will also solidify in a LN2-cooled cryopump. With proper valves installed and operated, you can make a laboratory-grade vacuum in a cheap way. After using the cryopump, be sure to warm it up and pump it out with your regular pump, to dry it thoroughly. As always, higher temperatures of the system being pumped will speed the process of evacuation. Water is particularly sensitive to temperature and will basically not pump at all near 32 F (0 C) unless the vacuum is prolonged and very deep.

plastic tube instead of welding was a good trick. thanks.

Neato! Another use for air tool bits!

WHAT IS THAT AWESOME LOOKING PEN

If you want to learn how to solder, first, clean everything with emery cloth and then use flux. I have a frig compressor vacuum pump and they work VERY well. You'll be surprised.

love your videos there are all useful and fun stuff

nice video you are amazing!!!!😉

Thank you! Keep up the good work looking forward to new videos:-)

you should try making a weak fusion reactor, not just a fusor. I made a tiny one using a vacuum pump and old high vacuum parts from ebay and scrap yards and ta refrigerator pump. if you need deuterium praxair sells it, you just need your own canister.

AWESOME projects on the way. Don't forget youre amazing

In regards to soldering the pipe... score and clean it first with a steel whool or steel bristle brush, then apply flux and heat just below the flux until you see it start to form a droplet and then run your solder across it in streaks covering the exposed surface. After that use the steel whool or steel brush again 👍🏻 then fit into the receiving fitting and heat and rotate until sealed and apply additional solder as needed 👍🏻

Great job on the video. Like your refrigeration diagram, however It is important to note that the vapor compression refrigeration cycle doesn't work with just a pressure change but a phase change with the refrigerant. There is a solid column of liquid always feeding the expansion device on the high pressure side which flashes to a vapor on the low pressure side. It is the condensing of the high pressure high temperature gas on the high side (Condenser - Hot Side) which releases heat absorbed by evaporation of the liquid to a gas on the low pressure side (Evaporator - cold side). Older CFC (chlorofluorocarbon) R12 "Freon" systems most commonly used mineral oil or a synthetic oil called alkyl-benzene (AB) for lubrication and are very benign. Newer HFC (hydrofluorocarbon) R134a systems use POE or PAG oils that are extremely hygroscopic (absorbs water from air) and turns to acid which attacks all components including the varnish on motor windings. If you were to attempt this you definitely want a compressor which has mineral oil or alkyl-benzene (AB) for lubrication. As mentioned by others refrigerant is used to cool the compressor motor windings and that heat is usually expelled by the condenser. Oil also mixes with the refrigerant and is carried around the refrigeration loop back to the compressor. Some compressors do have internal lubrication strategies and don't rely on refrigerant flowing in the system, but without the flow of cool vapor refrigerant back to the compressor, the windings will continue to heat up. If you do this for a quiet air compressor or vacuum pump, then keeping the load minimal and operation time short is critical for the lifespan of the compressor. The thermal cutout (unless internal in the windings) is external to the compressor housing and relies on refrigerant in the compressor shell to properly sense the temperature of the windings and shuts down the compressor if it overheats.

Nice video thanks , 👍 one of the guys made interesting comment that these usually have freeon gas in them which has oil lubrication in it for the compressor .. so surly running it dry will damage it ??

Anyone ever tell you that you have nice penmanship? Lol

Not sure if you were making due with what you had on hand (because I've done the same thing in a pinch) or if you didn't know, but the fitting that you pressed into the hose @4:27 is the male end of air line quick connector and not a barb that would be use in this case. Oh and the "check valve" you used is just a 1/4 turn on/off ball valve. I'm sure someone else already told you, but I just wanted to let you know. Hope you get to feeling better! keep up the great work!

Add a pressure chamber then you get a higher vacuum than just the pump itself, since those compressors have really small displacement but are instead extremely high powered for their size, actually add two chambers then you have both vacuum and compressed air from one unit. Old fire extinguishers should work.

It was still a good video. :) hope your well. (This should make you feel better if not) I learned something new the other day. I learned how to make a very cheep electric fence. (The hard way) lol.All you need is Christmas lights. Yep, almost may and I still have Christmas lights up. .. anyways... I went to take them down while they were still plugged in. They went across my chain link fence. Well, it was a little wet outside and I didn't notice at the time that one (possibly more) of the light bulbs were busted. So when I touched the fence I became the light bulb and since it was wet outside, it took a few seconds for me to release my grip on them. Yep, that beats any coffee I have ever had in the morning to wake me up. I am ok. So that is how you can have a electric fence for cheep. But I am curious to see how much my pg&e bill would be if I did leave something like that on. Would it constantly draw large amounts? Take care. Hope you enjoyed my "bright" idea. Ha

Great video, thanks! I need compressors for the vacuum system of my proton accelerator.

How would this pump handle liquids intake? I'm looking for a DIY vacuum for when I want to separate solvents under a vacuum condition. But this will cause solvents to enter the vacuum system.

I love your videos . I hope you feel better soon. copper and zinc works great for colds. as well as colloidal silver. get better buddy .

It was a good video, dude. Just worry about getting better, okay? Get well soon!

are you sure? that looks like a scroll compressor. also... what are you using as coolant/lube? those compressors usually require the refrigerant to be in the compressor as a lubricant. or the compressor will die much much quicker.

Nice Vid

So howmuch of a vaccuum does it pull? I dont see the description where you added it?

will you blow the pump up if you turn the valve/tap off?

you are SO awesome! Yeah I'm sending you mail, I might even send a few of my favorite electronic components too! :) It's on its way!

Are you using this to make your own components like Tesla? when he used shellacs or resins to seperate parts he would first vacuum to get out most air then allow part to dry under high pressure compressing any small air pockets that might have remained.

That's how terriosts will take over, by leaking Freon into the atmosphere

I Love you & your Videos

IIRC not a piston type pump, but one with a spiral drive(hard to image I know) - google scroll pump/compressor. Otherwise your fridge would be way louder.

Hi ;) Do you have any idea about making a tesla coil using socket electricity? Its 230V so ot could be really cool...

I shorted the pump and one of the coils burned. Can i start that pump with a circuit or something? One coil is still good.

Really nice, man. :) Try making a vacuum forming machine. ;)

this video wasn't boring it was awesome dude I had a broken frige we were going to toss away I didnt know it was useful until now. I could make a vacume pump and one question were is the Freon? i want to dispose of it properly

5:34 what's its vacuum capacity in mm of mercury ???? Is it capable to create high enough vacuum for x ray tube ( 10^6 mm hg ) ??

Thank you

After emptying the oil, what kind of oil do we refill it?

Hi, can you do one video about how remote control drones operate & how the circuit works?

I work on submarines and we had a significant slow leak on our a.c. unit on one underway. we had to keep going. after a week my body started aching and I got terrible migraines.

Nice Video, but I have to mention that I can tell you how much pressure the tube must withstand. The maximum possible is your local atmospheric pressure.

in the background it looks like you've REALLY been experimenting with Tesla coils! there's at least 3!

A video on how to make an inverter plz. I'm looking to use the induction heater powered by a car battery and need to step up the voltage in AC then covert back to dc

Notifications enabled

you ought to put a fitting on the output as well so you can use it as an air compressor too

can the same be done with an ok old ac?

It won't last very long. However this also works for building a silent compressor for using air tools.

my mom is happy because i decided to do mechatronics :)

That was about the most absolutely confusing description of how refrigerator works I have ever seen.

So how much of a vacuum did it pull? You promised to post that!

👍

what happens if you like suck up crumbs and stuff like a household vacuum?

hey bud......cool....... I'm pretty sure that those type of compressors have an oil solution mixed with the refrigerant gas for lubrication & cooling........not that it definitely wont function at all running it dry(perhaps at least for short periods of time)..........but it will most certainly VASTLY reduce its lifespan.

Can you make something that can fill painball air tanks? needs to pump up to 2000psi :D

hi best youtuber

Can you make an tutorial how to build that big Tesla Coil in the Background?

genial esos compresores son muy buenos hacen un buen vació pero también tienen bastante presión ese compresor debe ser como de un 1/3 hp yo solo tengo uno pero de un 1/6hp muy ben vídeo amigo

Piston? Clay? Minecraft!

I definitely want to see you create an x-ray imager... but, the number of other people across the country doing the same without proper shielding but a cheap building wall or shed makes me nervous. Also, cancer is a bitch.

LMAO HAHAHAHAHAHAHAHA too much ChaChaCha the first 2 minutes but informative, glimps of a genius mind. You're Smart, but Hands On LOL you get an A+ for effort. l liked that you thought outside the box and still got it to work. Thumbs UP, good video. i Like, OLE!

So.... how much of a vacuum can it pull? I don't see anything in the video description.

I have an advice the best way you can use this compressor is for pumping not vacuum it's so weak for sucking and it can reach 20 bar i guess

Good

Notification squad!

So how low is the vacuum?

Still waiting for USB killer video :3

have you seen codyslab before he made an old fassion mercury powered vacumme pump its an interesting video I wonder how much of a vacume it creates because its almost perfect if not a perfect vacumme

I once made a refrigerator out of a fridge compressor and I traded it for a key. They key opened a box on a boat at a local marina but to get to the box I had to buy the boat. At the time I thought I'd never get to see what was in the box, but one night on my way home from yoga class, I started thinking about gasses and things and how my mortgage wouldn't be paid out until it was paid off and as I trudged along towards an oncoming stampede of antelope, my downward gaze caught a sparkle that could be only one thing...a girl's best friend. The one that is forever. The diamond. As the herd barrelled toward me I curled up into the smallest form I could physically achieve, and as the beasts bore down upon me, I snatched the stone with my three-fingered hand and swallowed it dry. Now I'm's after having a difficult poop and a long canal ride to be meeting with my confidant Chum Lee, an international jewel dealer, and he knows a Scot living in Uganda who would give me enough to buy the boat. Soon I would have $3000 and the wonders of the box would be mine. I still don't know how to get the last of the butane out of my live resin, but the box may hold the secret...

Are you going to show us those Tesla coils in the background in action?

hey fun fact, you might be able to use that compressor to make a liquid nitrogen generator

super

now that I have a new phone I can watch your mediocre videos in glorious 1080p. jk I love ya

it's not freon on newer fridges, could have noted that specifically...

So three years later I wonder what Vacuum it pulled ? it was meant to be in the comments as said...............

About 2 years ago I had a fridge compressor blow up in my kitchen. Not even an old fridge but of course out of warranty. RIP ozone :(

Тема интересная Я тоже сейчас делаю. Использовал трубки для фильтра от воды

Electrical excitation of oxygen molecules in the upper atmosphere from lightning aids in the formation of ozone, many people (not you!) still think that it cannot be rejuvenated.

Please show the component name in your video, thank you.... from indonesian brother

Can you make your own cathode ray tube?

Where the fuck did my other comment go? Anyways add a pressure chamber like an old fire extinguisher or diving tank and you'll be able to pull a better vacuum, add another and you get compressed air aswell from the same unit. The compressor is strong as hell but it's displacement is minimal. Also if you haven't make sure to change the oil since it's made for freon not oxygen/air, it can ignite if worst comes to worst. All of this probably occurred to you already keep up the good work 👍

jm ikr

Now you have a pressure and vacuum pump for cheap :P

musical ZVS circuit please it would be awesome if you did

why every video is "be carefuller to not create a global catastrophe" the microwave gun than this

Yes, Freons (Kohlenwasserstoffe) kill the Ozone. Nice Project

can you make a video on why it works to make hydrogen from salt water?

5:32 you can't creat xray tube using 600 micron comp

Please upload a big musical Tesla coil video🙏🙏🙏

not powering brake lights?

What are you doing with it?????????
