- I need lots and lots of compressed air for sandblasting, but I'm on a tight budget and only have residential power. Let me show you how to create a rig with four compressors in parallel!
Transcript:
OK, Hi Kids! Welcome back to Hannah’s Bug!
To remove the paint and rust from my bug, I’m going to use a lot of sand blasting. Now, sandblasting requires a lot of air volume, not so much air pressure. Air pressure is measured in PSI while air volume is measured in SCFM, or Sustained Cubic Feet per Minute. You might think that I can buy, just, an air compressor with a really large tank, however, that will not work because the air tank will only supply me enough air for about 25 to 30 seconds of sandblasting and then the air compressor will need to refill the air and it’ll never be able to catch up.
For me to feel confident that I’m getting enough compressed air, I need to have 25 SCFM at 80 PSI. There aren’t many air compressors on the market today that can give me that on standard household 240 voltage. There are many on the market that can give me that on three phase power, however, on the street that I live on here in Teddyland, I can’t get three phase power off the poles.
One affordable solution would be to rent a diesel screw-type compressor. Those would really only cost my producer and camera-dog under 200 dollars a week. However, I don’t want to do all my sandblasting in one week, and to rent this over the entire course of the project would become extremely expensive, and I do not want to do that. So let me ask you a question. What would Chris Hemsworth do?
Chris Hemsworth would use multiple inexpensive compressors in parallel. Bernoulli got me these four compressors at about $140.00 each. Good boy Bernoulli! [Off-screen bark]
To run them in parallel, the air connection is actually very simple. You can see how I did them here, with more tube than 25 me’s. Yup, more. The final one. And now for the real problem: the electricity!
First, obviously, you need to make it so that each compressor is on an individual circuit because each household circuit only supplies 15 amps, while each compressor takes around nine. In simpler words, no 2 compressors in socket or else house go boom-boom!
So you’ll need to run a lot of extension cords. You need to plan this beforehand that way you get as short a run of extension cord as possible, because each foot of extension cord adds resistance to the circuit.
There are many problems to face ahead. The first problem is that reciprocating compressors have what’s called a duty cycle, which means that they’ll turn on so that they can fill their tank then take a break until it’s time to fill their tank again. Since these individual compressors are not in coordination, one of them may decide to be the hero and stay on all the time so that it burns itself out.
So I have to figure out a way to turn them all on in unison, but that will create another problem. It will create a power sag, which means there won’t even be enough current to turn them on, and they would all stall.
Each compressor has a pneumatic switch, which means the compressor will turn on when the tank is low, then turn off when the tank is full. You might just think that I can adjust these points so that the compressors are in coordination, but this won’t work, because the on and off points will change depending on the load. So I’m going to need to use electrical relays.
If these are my compressors, this will be my control, and these four will be my slaves. What would happen is, I would turn this one on, then there would be a 2 second delay before this one turns on, then another 2 seconds before this one, then another 2 seconds before this one, then another 2 seconds before the fourth slave. If I could see into the future, I would...

Someone is teaching this girl to be a tremendous value to herself and others. Incredible job on her parents part! Good for her for being interested in what really matters!
Haha. I was playing around with the idea of some kind of central control to make sure one of multiple parallel compressors under independent control doesn't burn up trying to fill all the connected tanks. I did not expect to find the relevant issues so well covered by a 13 year-old! Great job. Keep it up!
Doesn't mean she knows it all and wrote the info, could have easily been reading a script then edited together
Nor me I'm doing a similar project.
I raised my eye brows, shook my head, rolled my eyes, smiled SO many times during this video in amazement. I'm so impressed. You seem ridiculously knowledgeable. Your "producer" is a good father.
How do you know the producer isn't her mother?
because she has mentioned it
She is reading a script, Dah. Plus they way this is shot the video person/director is intensionally trying to sexualise this little girl.
@W Hoggdoc , settle down alright
@@Hoggdoc1946 Just because you get an HO watching a girl acting like a girl doesn't mean she is being sexualized short eyes.
There is more detailed technical information in this video than ALOT of other videos
I am impressed!!!! You rock!!
You dont really think she knows this shit. She is just repeating what her father says. I mean, its cool and all but damn.
You gotta learn from somewhere don't you?
I learned much of what I know from watching my dad as a kid. she does seem to understand what she's saying, which is what matters.
Yes, I agree, she seems to comprehend everything she talks about. And yes, sure, her father taught her, but she learned!
I highly doubt that. (The comprehension bit) but I do like that she is spending time with Dad and maybe she will some day. A relay yes but a bridging resistor, no. That circuit goes a little beyond V=IR.
I don't even know how to spell ardwino....I assume it is one of the blueberry raspberry pi dohickies I've been wondering about.
Hannah has single-handedly restored my faith in the American youth.
she shouldnt.... you arent supposed to run air compressors on extension cords because of the high amp draw... it can cause fires because extension cords arent usually made of the same gauge (thickness) of wire as whats in your walls... NEC (national electric code) calls for no less than 14 gauge wire in your standard 20 amp 110 outlet.... (important to note that even though the outlet itself is only capable of 15 amps the breaker is usually 20amp).....
in summary during prolonged use the extension cord wire could get so hot that it would melt the insulation off of it and cause an electrical fire.... this effect is magnified by the length of the cord.
you do realize that a large majority of grounded extension cords sold are 14 if not 12 gauge. Unless you are buying the absolute CHEAP crappy extension cords you will be getting at a minimum 14 gauge. Also the duty cycle of the compressors will never allow the heat to reach that point in the cord or construction work would be having fires left and right from compressors running on extension cords all day while we do things like roofing or framing houses.
pmoore4321 how old is she? She seems pretty smart for "youth"
she just turned 34
Impedance in an electrical conductor is as much a function is length as it is gauge. She mentioned earlier to keep the lengths down. She'll be fine.
Wow. Simply astounding. Someone has a Masters in electrical engineering. You have spent some time researching this for sure. You Just found a way to build a $7500 dollar compressor for about $600 bucks. I have heard there is some crying in the comments about this or that but who cares. What you set out to design so you could restore your Bug on your terms simply impressed the hell out of me. You young lady are the most impressive youth I have seen in quite some time. Bravo
I cannot believe the petty, insecure, and negative comments. Absolutely thrilling. This is HER solution. She invested the time to comprehend and implement. Everyone must learn somewhere. Clearly very gifted and intelligent. A note, there is a lazy solution to mechanically couple. I tracked down a US mfg that makes a phenomenal, all metal yet cheap check valve. Sellorcity on amz. I operate by pairing down into a single connection. I have two pairs of eight gallons. One mobile, and one fixed. Each pair uses this check valve joined at a T. I then have an adapter so I can run two 3/8 lines and join at the destination, or join at the pairs. Same idea. I made sure the pressure sensors cut in within a threshold. Also, drying the air is important. I recommend the check valves on quick connects so they can be oiled once every six months. I must use dedicated 15 amp circuits for each as they all synchronously cut in. I solved the frequency by pairing 7 gallon Kobalt tanks to keep mobility. I also configured the couples and check valves so I don't need every compressor on always. Not as refined, but fast and dirty. Also, check out the Makita 2HP oiled 2.5 gallon. I'm building a new array, and these peaked my interest. Taiwan made. The quality appears to be leaps over the last gen CP compressor that was very efficient. That would be the one with the crank exposed towards the handle. For performance expectations, I can run tools rated > 14 cfm.
simply amazing. I searched on how to connect parallel compressors and watched 12+ minutes of me feeling like I need you to come do it for me. I've a math and computer degree and struggled to keep up. Excellent job! I'm having my kids watch and learn. Thank you for educating the world! Proud of you!
you just restored my faith in this current age of youth! glad to see there's kids/teens out there who have taken up a hobby and passion in mechanics/electronics/engineering rather than out on the streets in the middle of the night raising hell, getting high and causing trouble. keep up the great work and will be subbed for more videos! :)
its crazy! why does no one have a real hobby!? in my electrical engineering classes, unless they have work experience with the stuff have no clue about the simple things! my class is 3 years in and they have never even used a transistor on their own! I was using them on my own when I was a freshman in high school!
I used transistors when i was about 7 years old... Maybe You are right, this generation will be rised with computers and smartphones, i think her dad did a great work to led her into the trial and error of real things and using her own fantasy to create things and come up with solutions and find out if it will work or not on her own, but with hi´s assistance i guess if things hawe a potential to become dangerous.
Aaron's Vlogs the term is mechatronics. A lot of young people are taking it.
Defdakilla41 sad part is there are not more people willing to use their minds. But I suppose that's how it's always been. There just happens to be more people on the planet today. Your kid could end up being a Nobel physicist one day. Never know.
She 36
The best video on YT for slaving multiple compressors. Well thought out, planned and executed. Girl Power, well done Hannah.
Im an electrical engineer and I think this is great; keep up the good work ! The comment about a diode across the coil of the relay you are controlling with the transistor is a good one. When a relay coil turns off, it generates a voltage spike due to the energy stored in its magnetic field. This is known as a "flyback" diode.
Ive never been so proud of a child that wasnt my own... speechless.
If your dad is the secret off camera engineer, You have the father of the century
it's a great collaboration, what a TEAM!
also might be her mom,sister,brother/dad /just HER no matter what the presentations are GENIUS!
I’m most impressed that her dog is the camera operator.
This series is awesome, so glad I found it, but I'm sure it will be painful to watch for Hannah when she gets a little older! 😂
This little lady's future is looking brighter then the sun itself. She makes great informative and entertaining videos. I'm 42 and can't break this info down to my son. But after watching her he was able to teach me a thing of 2. Now my whole family loves her videos.
Keep up the awesome work!!!!
I remember this from some years ago. You’re an amazing artist .❤
hilarious i search for a video on how to chain compressors and find a very informative video by a (silly) girl :) ...provided all the info I needed
Haha (weird) girl
super impressed. electronics, software and mechannically savy.
I can't even say enough about your knowledge and drive at your age. You remind me of myself when I was young and repairing appliances with my dad in his shop. I learned so much during those times. It's everything that contributed to who I am and what I do now. Excellent job!!! I wish my own 2 sons were interested in these things even 25% as much as you are. You have brought a smile to my face and given me hope for the next generation of DIY inventors. :)
At first I was like "what the hell is this and I'm wasting my time", but then I was drawn in by your knowledge of everything and your sense of humour. Did get a good laugh at the burning house comment haha. Keep up the good work.
What ever became of this young lady? She is so talented but her videos just stopped. We hope she is okay.
girl power.... (with i think a lot of Dad power)
but thats perfectly ok
Can you not accept a girl being good at engineering thats funny
Il Dxnny lI can you not accept that this girl is very young and MOST LIKLEY saying everything her father has told and taught her? Lmfao. I’m sure Erin can accept a women being good at engineering, can you accept that this is most likely a father daughter bonding thing and that she doesn’t know all of these things off the top of her head like it seems?
@@Snoophouse66 Exactly. Men today are so sold out to this trendy "girl power" thing that they lack the discernment to see what's really going on.
I think her brilliance is clear. And I doubt that her parents are stupid... probably engineers. I've known engineers kids before and they not only get the genes they get the tech know-how and an environment that results from all this high IQ in the house. Getting help or inspiration from mom or dad takes nothing from this ladies intelligence and charm.... IMO
tom feiller who said their parents are stupid? We’ve all said that she’s probably learned what she knows from her parents
It’s 2023 just found this channel what happened to this impressive lady’s channel it seems it was short lived but informative 😊
I'm in my twenties and still struggling to keep up with this young woman's amazing DIY lessons!!
Because you don’t have a mentor as she does
I wish I would have started working on cars when I was in my early teens.
Yup! Through all that trial and error I have become a genius! ;)
I don't have any idea how I stumbled on this channel, but I am definitely impressed with Hannah. Running a lathe, sandblasting, building Arduino protoboards, programming, fiddling with compressor air de-watering homebrews... I'm in awe and wish I knew girls like this when I was her age.
Good lord. I can't explain how thrilled I am to see such a bright young girl applying excellent theory. Having a daughter myself, I hope she takes to my love of building and mechanical applications as much. I'll admit that I will be using this trick and some of your portable garage Info so that I can also blast and finish my 72 challenger project. Cheers!!
somebody in the family is an engineer
David Northrup wish I was an engineer . ha knowledge is power ;)
There is absolutely an engineer in that family. What is impressive though is how well she explains it. To convey what she has as well as she has involves a high level of comprehension for the subjects. Can't wait to see what prodigious youth like her create in their lifetimes.
Or a mechanic, like myself.
Nah. They probably wanted to but couldn't so they groomed her to become one. She's spent her entire life in that shed for this moment. Jk
@@cermit2376 lmao
I think you'd be more suited to my engineering degree than I am!
Very nice! I'm getting older, but I have not met a girl who understands so many technical things. Most of them drank in a drugged young age. They do the university, but they can not think much about themselves and want to get everything ready. You are so different! :-)
Mercy! My 62 year old brain lost track about 20 seconds in and I've decided the easiest and less expensive way is to purchase 1 60 gallon, 3HP IR compressor for about $850 and run a 240 line to it. Having run my own body shop out of my garage years ago I know it'll do almost anything I'll ever need it to do.
Anyway, I guess you're about 18 or so by now and about to graduate college and take over NASA any day now so more power to you!
My alleged son was smart like this when he was that age, except his interest was in old farm equipment like hit-and-miss engines. It wasn't until he was in his late 20's and returned from 8 years in the Air Force that I realized how depleted my scrap metal pile had become because of all his projects.
Excellent vid, TBH never thought of combining cheaper lower amperage units for an increased CFM rating to get jobs done. I see a lot of criticism and official "air compressor inspectors" up here with plenty to say what is wrong, but it's my understanding you built this with a particular mission goal in mind and I'm absolutely certain you achieved it lil lady :)
(I thought I was doing good saving up for an 80gal 240v deal, now that I checked the CFM rating on all my picks knowing sandblasting is definitely part of my long term goals, I'm honestly considering two cheaper 60gal 120v deals lol, the arduino part is not a problem)
Absolutely fantastic.you remind me of my youth.I would spend lots of time across from my house at a tv repair shop.They also had metal working machinery a giant three phase air compressor he bought the pump,big tank and ten hp motor used and assembled them .Also there was This postal delivery man he would always finish his walking route early and spend about three hours there every afternoon.He quit his job as a professor or physics and chemistry early on because he hated the job.(what a waste of education)I learned a lot from him.My BIGGEST regret is not learning the mathematics every one told me I would need.Math is the most valuable tool you will ever possess.I am sixty years old Even though I am very intelligent (and modest)it is too late for me to learn it by my self.
Words cannot actually describe how great your family is.I spent forty great years as a union construction Forman.Keep having fun and learning learn as much as you can.Al from Twinsburg Ohio
This girl is scary smart.....I know electrical circuits and she seems to do electrical circuitry is a easy as preparing a bowl of cereal for breakfast..... lol........Crazy impressed
will save your videos and pass it to my daughter when she grow up :D.
Cuong Chu Pass it down to your son's of you have any too!
Your going places young lady!
You go girl! It's refreshing to see a smart teen that's full of great ideas and that is interested in building, restoring and acquiring a ton of technical skills. For a long time I thought I was the last one of a dying breed (since the time I was your age and even younger). I wish you nothing but the best with your Beetle!!!
Hannah where did you go please come back the world needs more like you.
With all the self righteous, sanctimonious pricks hating in the comment section, she and her dad probably said fuck it. The know it all jerks ruined it for everyone as usual.
SCFM=standard (not sustained) cubic ft per minute, standard means at atmospheric pressure ...anyway your a cute and smart kid...
Wow - You are correct sir! Great to learn something new!
New video coming soon ? :D
Since this is a summer project, mostly Bernoulli films during the summer and then edits in the off season... But I think he's got a new episode edited that he'll upload within the next 24 hours.
:D Can't wait to see it
Were you seriously cutting your hair while explaining this to us? Are we boring you? lol Nice work.
Just a little trim ;)
What a smart kid! So many other videos from tradesmen don't even touch this one. I haven't seen one that addresses the electrical and the compressors are just paired pneumatically. Good job professor!
Excellent video. I just don't know how a teenager can be so knowledgeable about all of this? Really amazing! You are the smartest teenager on the planet.
Always remember to add your back EMF diodes across all relay coils :)
Alex Powers, why?
I would guess a preventative measure.
your dad is a freaking troll. this is genius. i genuinely feel belittled at times. well done. really hope none of you get into a car accident some day
Hannah, you are absolutely awesome!
I hope your going into one of the engineering fields, we really need people like you.
When do we get new content? I’m curious as to how the build turned out.
This video is 4 years old. She's a Portland protestor now.
That’s kinda harsh..... but ya never know
@@stevenboykin4709 She probably went to college on a full ride, she's smart.
I admire your ingenuity, energy, and intellect, but something to consider when you are designing your stuff. The KISS principle. Back in the early days of space exploration one problem they had was ballpoint pens wouldn't write very well in outer space. The USA solved the problem with a $250, 000 (a LOT of money back then) research grant, the Russians solved the problem with a $1 mechanical pencil.
Your system is subject to a lot breakdowns because of the complexity of your system. In addition the compressors are all turning on even when you are only using a small amount of air (excess power usage) and I can see where there could be a short cycling (off, on off, on) problem causing premature failure of the motors and more power wasted from the high amps pulled during repeated start ups. Probably a lot of excess noise as well at times. BTW, air systems are like electrical systems in that smaller lines have more resistance to flow, increasing the size of your airline might allow you to get by with less power or fewer compressors. Also, generally speaking, bigger compressors are more efficient. Small oiless compressors use a different tech than bigger compressors.
I built 2 less complicated solutions years ago using small compressors to save space in,a mobile shop. The small units could be stuck inside the vehicles frame and take up less space, use less power most of the time, and I could use smaller, cheaper inverters.
Solution A involved 2 compressors. I connected the air lines together in a common manifold and I simply adjusted the switch on one unit to kick in at a lower pressure setting (I had to scrape off the epoxy used to keep the adjusting screw in the switch from moving due to vibration, adjust the screw and epoxy it back). If the first compressor could keep up, the second compressor never kicked in. Took 15 minutes and some JB weld that already had laying around. I suppose you could readjust the cut off pressure lower also to make it cut off earlier too, but I never did.
Solution B involved three compressors. All 3 had the pressure switches set up to cut off at 120psi and turn on at 90 psi in the tank (factory settings) Basically the same concept only setting the air regulators at different pressures 90psi, 80psi, and 70psi and a fourth regulator close to or at the tool to control tool pressure. On startup of the tool when the pressure dropped below 90psi the first compressor motor kicked in, if the pressure kept dropping past the regulator settings of the other compressors each would start supplying air as it reached their regulator pressure and each would start up their motor as the pressure dropped below their switch settings. You could reset the regulators, if need be, for different situations. Cheap and simple to diagnose and repair. In your situation, with the addition of some ball valves you could disconnect the compressors and use them indivdiually or any combination very quickly.
With both systems, most of the time, there was only 1 compressor running, the rest was in reserve. I am sure that a hybrid of the 2 solutions would work also.
Last, but not least, I would like to remind you to be careful when working with any system that can turn on automatically or can be turned on remotely by someone else. Be sure to disconnect or lock out the power. Some systems common around the house or shop are: air conditioners, refrigerators, air compressors, vacuum cleaners, blowers and fans, lights, anything that can be set on a timer or sensor, or connected to the latest danger, "the internet of things".
PS. I'm probably biased because I'm not smart enough to do it your way
In solution A, I misstated "I connected the air lines together in a common manifold ". I connected the 2 tanks together so that they acted like 1 large tank with 2 compressors feeding it. Hope it is more clear now.
Solution B does have a common manifold that all tanks are hooked to but each compressor is feeding its own tank and all tanks are feeding the tool..
FYI, that story about NASA and ballpoint pens is a myth.
On what do you base this revelation?
I assume you meant that question for me. I based my comment on what I had assumed was, by now, common knowledge that the story was apocryphal. However, to support my revelation, I have a friend who knows a lot about things like this, his name is Google. To wit:

Hannah reminds me of Jeri Ellsworth: race car fabricator and driver, computer entrepreneur, and chip designer, an extraordinary autodidact. Perhaps lightning has struck twice.
Great Hannah, you are teaching a lot of boys too, good on you! and you have a great Dad!
Awesome! This is planned very well. Though instead of a standard electric outlet, perhaps a GFCI?
How much of this stuff do you figure out on your own?
MrTrollgubben none
I'm glad your consulting an engineer or professional. Nice work.
Hanna, your the bomb,
Hope to see more of you in the future,
Your parents are great Americans
Is this Alton Brown's daughter?
Dang, nice job, are you an electronics engineer also? your pretty smart! Nice ending lol
Bruh she like 12
Holy crap this kid is smart, even if it is memorize and regurgitate. Well done.
Ruin for resident, Hannah. You are a legend, girl !
I'm working on my 1989 f350 lifting it and doing body work and I'm 14 year old
Awesome Lucas!
Yeah well I'm fukin 13 and lifting an f450
One upped yo ass
is that an f450 durramacummins with a turbo diezal???
Tom Tommy pfft I lifted up so many things my jacks tired
Really girl buy a big auxiliary tank and connect it: job done.
its really great seeing a young lady without her head stuck in the phone like a zombie your so smart and talented its refreshing to see your not lazy your a go getter good luck in everything you do i feel you will go very far in life short stuff god bless !!!!!
Dude i swear this girl has a big brain make me look dum shes so smart glad to know their kids like u willinh to leanr and teach
For $300 more you could have bought one compressor that puts out just as much air with about half the current draw and still small enough to run on single phase although 220v but most all houses have 220 someplace. Worst case it would be far easier to install a 220 breaker than some sort of over complicated rely board.
They could have bought the smaller 220 unit at HF and been done with it for the same price they spent... They would have gotten the cfm and volume. These unit only put out 4-5 cfm at 90 psi.
She says seeds 25 scfm at 90psi. What compressor at harbor freight can output that much?
She also mentions she can't get 240v 3 phase so that rules out any of the 10hp + units that usually cost 2k+.
These 10 gallon hf compressors are 2.5hp each and put out 5.3scfm@90psi. They also cost around $120 on sale. So for $500 she got 10 hp and 21scfm @ 90 psi. Tell me again how spending $800 on the hf 60 gallon which puts out half the power is a better idea?
SoDiezl350 Thats bullshit. The biggest one that HF offers is 17 CFM at 90 pounds. Its $649 on sale. 220 SINGLE phase. She said she couldnt get 3 phase power. She said nothing about 220 single phase. Home Depot, Lowes, Nothern Tool, Air compressors direct and several more places have compressors that fit her needs and more for just a bit more than what she paid. This is just stupid and risking burning the house down. A also hate to break it to you... They are 2 HP compressors and only 4.5 CFM at 90. So your calculations are a little off... Next time do a bit or research before you talk out your ass...
@@robby844 I don't think you can have 220 single phase in the typical house, pretty sure it needs to be at least two phase to get 220.
@@ZeroEntropy. Uh.... You stupid or something? Its either single phase or three phase... Three phase power is ONLY available in commercial OR industrial coded areas....
I have built and repaired many industrial controls from scratch, the few concerns i have with this is that first, you are using a wooden enclosure to store electrical components and any well designed enclosure must be able to contain a failure from a short. The wooden box is literally a fire hazard. Second it is very bad practice to mix multiple power sources that are controlled from a single board, there could be a short and jump between phases.
What could be a safer and more practical solution would have been to use a small breaker panel with two 15a tandem breakers running on a 240v 30a welding circuit. This way you know that all of the components would handle a short and withstand the current. This also gives one disconnect point for safety and you don't have a risk of a cordset getting pinched or causing a hotspot with all of the plug connections. Also the idea of using the programmable chip is nice, but you could have also used a simple time delay in line with a 120v relay or even a time delay relay. These offer a easy and fast way to update your sequencing.
I can appreciate a homebrew design based on things in practice, however this design should be upgraded for safety reasons and simplicity.
Funny, I sandblasted 2 1936 Ford Bodies with one 5 HP Sears Compressor using a professional sandblasting rig with no problem. I believe my lines were larger but had no problem. The trick is to keep the compressor cool using a fan. The cost of my compressor and sandblasting rig turns out to be the same as yours with less headaches. My unit is 220 V.
You have a good head on your shoulders , don’t let anyone steer you down the wrong path! Nice to see young people working with their hands & minds rather than face planting a phone screen!👍
Great video but can I make some suggestions? Your delivery sounds like you are reading it straight from a script. Try reading your script first, then turn on the camera and rephrase what you just read into normal 'speaking' words, like it's just a conversation you are having with someone. It will sound less forced and more natural Also you might like to tone down the quirkiness from a '10' to a '7'. Never go full quirky. :) Keep them coming though. Great stuff!
there is no way that you've learned all this stuff at the age of 12. wth I was playing video games and going outside at your age.
I am impresssed young lady. You studied your mechs and have a sponge for a mind. More input for you. You have it in you to be an engineer of many disciplines, keep it going. Awesome.
Very well thought out. I'd suggest adding a watchdog into your microcontroller circuit. So if your Arduino freezes up the watchdog will restore order. Even if your code is perfect. Mills timer will overflow. I would use it without provided I was aware to pay attention to the blower off valves when using it. And when not killing power to the controller
I just got my ass handed to me by a 12 year old.
ReDevil, her father or mother provided the insight to school you. This knowledge far exceeds the typical 12 year old.
Mr. drjjlj and all the rest of you people just need to get up off Mr. Collins back and leave him alone. It's oblivious that he does not have one real friend to talk to, so he watches little kid videos and argues with people he'll never ever see or meet just to keep from being lonely. Mr. Collins i got your back, cause i'm lonely too. Mr. Collins we'll show Ms. Thang, Hannah bug our 2 compressors in 30 years. Boys won't she be jealous.!!!!!! And next year were gonna go on that Ms. Thang, April Wilkerson site and get on her too. Who these girls think they are? When everyone already knows that you are the one-and-only true compressor Guruuuu.
I have been trying to find a way to connect several small compressors for an increase in CFM for a long time. Now I know. Thank you and good luck with your Bug
Extremely useful! This helped me setup my own parallel system with a Raspberry pi. Thank you!
its brilliant but has room for a lot of breakdowns as well. 1st of all, 4 compressors that are oiless...omg, you cant possibly have neighbors or be working in the same room. 2nd is you have 36 amps load just to fill roughly 40 gals of tanks and you have 600 bucks invested plus all the extra relays and power box so lets say 700 bucks to be conservative. not to mention all the future issues with 1 relay or switch or compressor that affects everything downstream. i have sandblasted for 20 yrs so i know your situation all to well. and i tandem 2 compressors as well to sandblast simply by setting the switches cut in and out the same and run both air lines to a T and a 3rd line off the T to the blaster. i am only pulling 16 amps total load, i have 18 cfm output, and 45 gallons of air and i can run the blaster constant for over an hour and maintain 75 psi. i have 100 lb blast pot so about an hour and im out of sand anyway. and believe me, 1 hour of blasting and your ready for a break anyway. i love the theory but the KISS method is better. half the electricity, double the air volume, oh and half the noise due to mine are oil bath compressors. you also will be buying 4 more in 5 yrs or less because of no oil...both of mine are from the 1980s and still going. the only difference is you did get out cheaper on the initial investment of 700 bucks. my 2 would cost about 1000 in todays world...but i will make up that 300$ difference in power bills vs yours in 12 months or less. keep up the good work, happy blasting and if your within 50 ft of those things, in addition to the standard respirator and sandblast hood, you will also need ear protection because they are insan
Those are oil-lube compressors and an incredible value when they're on sale at $99. They're loud like any direct-drive compressor. Another consideration is when she's done sandblasting she can sell two of them and still have plenty of air. However, I suspect the bug is merely the beginning and she'll find plenty to do with all that air.
Ok so u got me on a technicality, yes they are oil lube, but not a true belt drive oil system that is super quiet. I can run my 2 and have less noise, more cfm, more gallons storage, and less cost...and not have shit for compressor. Mine are 30 plus yrs and i could sell tomorrow for $200 each...these i. The vid will resale for $50 the very next day if she is lucky and 30 yrs from now, they will be just a memory, kinda was my point and you kinda missed it ;)
And theres no way she is doing much sandblast with those 4 toys. Maybe 30 seconds at best and shes out of air, then a minute later, maybe another 30 seconds of air...smh. god if she gets rid of 2 then she mights as well use a tire for air :). But seems like you know what your talking about so..... how about this: post a video of this exact setup sandblast a rusty car rim. I wanna see it. Id love to see her attempt to do whole rim just to see the sand stop at 30 second mark. My setup will do that rim front and back without stopping. Uses less amps, has more cfm, more gallons, longer yrs service and you actually have something worth something a yr from now...do a video of these 4 compressors 1 yr from now...3 of them will be replaced by then...great value! !. Yeah, you kinda missed that point too. :)
Michael Collins, 2 summers and counting. All four are running smoothly.
Ha, mine are 30 plus yrs. Get back with me in 30
SCFM = "STANDARD cubic feet per minute." Do some research to learn about the "standard" part.
I built the Arduino assembly according to Hannah's instructions, and it worked! However, and perhaps I am mistaken, the unloading valves on the particular HF slaves that are used in the video are simply mechanical check valves that are operated via springs, and they automatically release pressure above the cylinder heads when the cylinders stop moving....therefore the unloading valves do not have to be unscrewed slightly to release pressure above the cylinder heads.
Jesus Christ just buy the kid a late model car. Kidding....very cool you are giving her all this knowledge. She will be head and shoulders above engineering graduates before she gets out of highschool.
Please PLEASE stop!!! The "S" in SCFM does NOT stand for "sustained". The "S" stands for Standard as in Standard Cubic Feet per Minute (SCFM). The "Standard" is defined by CAGI or Compressed Air and Gas Institute. Your controls will cause electrical fires. I've seen way too many cheap-o solutions like yours lead to disaster and heartbreak.
Your video about making a desiccant dryer using PVC is creating a HUGE danger for unsuspecting people. You don't take in to account the fact that PVC degrades when exposed to sunlight, heat of compression, vibration and synthetic oil. PLEASE, kid, stick to what you know. In my 42 years in the compressed air industry I've seen way too many people killed and maimed using methods very similar to what you propose.
Ernest Havner don't hate
I have a video of a proper system with proper controlls
Ernest Havner Give her a break. It's impressive to see someone under 18 trying to do something like this given that most teenagers these days just waist all their time on Facebook, texting or whatever new thing the cool kids waste their time on these days.
Ernest Havner the kid said she's only running 80 psi max. Schedule 40 pvc will easily handle that without degrading for years, if not decades. By the time this system has aged, I'm sure she & her "producer" (aka dad or mom) will have built a unit out of stainless. Btw...my "hugely dangerous" home made dessicant system has been in service in my barn for nearly 20 years in a 135 psi system. Should it someday schrapnel, you'll be the first person I contact to admit I was wrong. (No, it will not kill me as it's with the compressor up in the loft on a piece of 1/4" alum plate.)
Russell Fisher that’s not hate.....
also the girl power get old fast. and in my opion make you look lame.
Smartest younger person I have ever listened to. Go girl!
Oh My gosh. You go girl. I had boys but if I had a daughter I could only dream of her being as awesome as you are. Nurds rule, stay in school and give your folks a hug from me, one parent to another. They must be fun to help provide a space for you to shine.
Have a GROOVY Day, tommyj
Stumbled across this video searching for "air compressor control". Creative setup, and you're awesome. You've gained a subscriber. Another option is to pick up a larger compressor pump and motor at a place like Harbor Freight. The pumps are often on sale and you can find a 5HP 240V motor surplus or scrap fairly cheap. Then mount that on your existing compressor tank. That way you don't have to deal with controlling multiple compressors, draining them, plumbing them and it will be more power efficient. I did something similar on my Campbell Hausfield (see my channel, it's in the videos somewhere) with a 5HP motor and 14 CFM (at 90 PSI) twin cylinder pump. Total investment was about $150.
Cute as a button, and sharp as a tack!
all it takes is a good parent. i was like this too as a kid because my dad was a crop farmer truck driver who also knew house wiring concrete all kinds of fun stuff we built 2 houses to gather. he never gave up or failed at anything. ultimately i mean...he would someones screw up and it was mostly hilarious. so i learned ALOT from him and sometimes with him. he showed me how to get things done even when i don't feel like it..to just push on and do it!..
I admire your project. Honestly.
Excellent vid.
Hannah is a great talent with a massive future... 👍
Even if somone else did the math this is one smart cookie, I'll bet she's bored in school!
I wonder what class she teaches? Look at that sand blasting, woodworking electronics house wiring, what is she not doing provided she's working with all these tools.
Even if the camera man is telling her all this stuff she understands it pretty darn good.
I'd thought about running 2 compressors for more output air but she's showing us how to do it better. And Sandblasting? by some machine shop tools and make a screw drive compressor. or find a broken scrap one to rebuild.
7 years later still great video!
Fuck Einstein I am close to 3 times your age!... Been a DIY'er all my life!... I understood the part of hooking up multiple (cheap compressors)!... Makes so much sense!... After that I lost you and I started admiring your enthusiasm!!! Thanks, I liked, subscribed and watched till the end (as required of a "good" boy 😉)... You are a great teacher, unfortunately my brain is not on the same level as yours!... In future I will watch ALL your videos, mainly for your enthusiasm!!! Despite us being on different levels, I will still learn a lot from you!!! Please keep up the good work!!!... Most of all, keep up your enthusiasm!!! 👍👍👍
Saw this video around for years ago and had to come back to it today because it's finally time to build my own
Absolutely epic Hannah. I hope my daughter will be like this one day. Absolutely brilliant. You rock ;) Well done mum and dad for raising such a fabulous girl :)
Your father is the man👍🏻 way out of my knowledge. Kids need have more skills like you do! Awesome job.
We miss you Hannah.
Right now i will send a message to the TH-cam asking him changing the like button and allow more than one like ... one like is not enough you deserve millions of like for your information and the way you talk ... thank you keep going
I don't think your average home owner would want to get into electrical engineering just to do this.. but bravo!!!
So sad she didn't post more videos.
I think this may be my favorite video as far as your mannerisms and funny expressions go!
Wow now how perfect does it get. I just bought the exact same compressor a few days ago and am adding additional storage capacity with a portable tank to get a bit more out of it. That is quite limited though. The electronic distribution delay on relay box is what I'm going to give a try at. Only difference is it will be for just two compressors so that much easier. BTW coincidentally this is the first video I checked out and that also covered the electrical/electronic subjects. Yupperz... Perfect.
Thank You Very Much.
