- Correction: The power is actually 3.8 W and not 38 W. Ma Bad!
Torque is a very important part of the world around us.
Almost every machine around us uses levers in one way or another so it's important for engineers, designers, and builders, to be able to measure this rotational force.
In a general way, is possible to separate torque into 2 categories:
-Static Torque;
-Dynamic Torque;
Static torque is very easy to measure, so the core theme of this video is how to build a simple and cheap device capable of measuring dynamic torque or torque linked to a rotational speed.
The final result is a device that uses an Arduino, a load cell, some 3D Printed parts, and electrical components
to measure torque.

this channel deserves way more subscribers!! brilliant content! keep it up!
Thank you so much Bradley :D
It’s criminal... this channel is aaa quality! I hope he keeps it up!
I was thinking the same thing. The amount of hard work he puts in his channel is great. I always learn a lot! Thank you for your videos, Integza!!!
Very impressive!!!!👍
@@integza this aged like fine wine
"A drinking game you say?"
*Looks at length of video.*
*Looks at bottle of cheap Scottish battery acid on the shelf.*
"Might just spectate this round."
Looks like Scotland have some nice names for their drinks.
Last time I was there I got a beer called "Used engine oil"
I was thinking to myself "...if i played with alcohol I might well be dead by now" halfway through this video.
Can confirm drinking is a bad idea, not Making that mistake again
Over the course of 3 days you have become one of my favorite youtubers, such awesome ideas and builds! I’m a recent mech engineer graduate and had no idea what projects to work on until I seen your videos.
I love you. This is quality quality stuff. I'm ajust getting started in open source engineering and your content has become something I look forward to every video you post. You not only educate but I like you as a personality. Keep it up!!
Your channel deserves to have soooo many more subscribers. Your content is super interesting and original.
Really refreshing tbh ^^
Thank you so much :D
The amount of work you put into these videos is great. I appreciate your humor while teaching me new things
Also, soldering tip (pun intended): Get the parts hot before you melt the solder. That way the flux covers them and the solder flows over them. Your trouble at 7:42 is because you weren't heating the pins.
And don't use fake cheap chinese flux and solder.
@@paulcohen1555 also also, clean the tip with a bit of brass wool, de-crap it with flux and tin it with a small bit of solder. Dirty tips give bad solders.
Good work man. Your content is exactly what we all need more of. Especially the youths that need direction. Keep it up and thank you for sharing this with the world.
I just discovered this channel, and let me tell you, it's awesome. Educational and your sense of humor is on point
Thank you Ruan :D
Very good combination of technical and Comedy : brilliant explanation of static vs dynamic torque
Aw man I really enjoy your content, I hope the TH-cam algorithm is nice to you and that your channel explodes. Because this is some quality content
Thank you so much for that :D
ahh my man. i thoroughly enjoyed this video. i learned a lot and your song is going platinum
Super stoked that I found your channel. Keep it coming 😉⭐
I already love this channel. Also if you soldering, first touch with hot iron tip pads and pins. Then after 2 seconds start melting solder! Your pads are too cold to solder, you must preheat it! That's why solder not sticking to board :)
You have such amazing videos that get me inspired to design and create! Much appreciated buddy your doing the world alot of service. 😊
hahah si nu grand comba' stai fuori come un balcone!!! Watching your videos make me feel the stress of the competition in which I may graduate in electrotecnic a little less painful and anxiogenic!! Thank you!
You are a such a talent man. You should have millions subscribers.
Your content are incredible valuable and very entertaining
Thank you very much!
Great production values and content, I'm sure more subscribers are on the way!
Thank you :D
Thanks so much for sharing your model! Awesome work getting this working.
Thank you for that comment :D
Kudos on your videos 😊
I see this video is about a year old, and much has probably happened in that time, but I just wanted to give you a few tips about a couple of things:
1.: Dynamic torque:
If you have the effeciency, the current, and the voltage of the generator, you should be able to calculate the output wattage, and the torque of the turbine.
2.: Soldering:
Get a better soldering iron, clean the area (as little as a fingerprint can have a negative effect on the result) you are soldering and/or use flux (it will make a world of difference. The flux cleans the surfaces, and makes it easier for the solder to flow, and it makes the tip of the soldering iron last longer), solder at high temperatures (I find that 350C (48W soldering station) works for most normal PCB soldering (add flux, heat surfaces for a couple of seconds, add solder). I hate it, but leaded solder is the easiest solder to use. Unleaded solder will eat a low quality solder tip in no time, giving you an uneven surface, causing the solder to stick more to the tip, causing bad results - again; flux mitigates this, but a good soldering iron, with a good tip, will still make a big difference.
I just discovered your channel yesterday when looking up info on turbines. What a gem! I subscribed within watching one video. You clearly put a ton of effort into your content and you're pretty damn funny too :) Great content! I'm going to tell all my engineer friends about you channel, I hope you get many many subscribers!
That comment made my day!
Thank you so much :)
Your videos are interesting AND FUNNY. New level in making science and technology closer to ordinary people. LIKE :)
I'm was amazed when I saw the bottle of Beirão and realized you were actually portuguese. So proud
And you make these videos so entertaining, you're quite the smartie :)
7:42 buy some soldering flux dude, your life will change forever
The saddest part is that I use flux XD
Oh... what an awkward moment...
@@OlivierLopezCh Awkward was when I tried to sing ahahah
@@integza That was beautiful. For a moment I thought my wife was playing Andrea Bocelli
in the living room
Also ditch the round iron tip. Seems the guys that do circuit stuff a lot (EEVblog or Big Clive are the ones I watch) say round soldering irons kind of suck. An angle tip is better for transferring the heat.
I have died 4 times now from the drinking game. Expect to hear from my non-existant lawyer, señor cactus, when he finally stops shooting gatling lazors from his flying cyborg shark
Captain Diomedes wut a cyborg shork
Damn, I'm gonna have to play New Vegas again.
Uh...
Don't use alcohol. Use chocolate milk. You won't die 9 times and wait for you t Rex lawyer to be done shinning a dime for a jumping goat is going to get you 45 bucks for a heart attack as the cause of deathcyther 5g jaggy rock solid wall
Once again, great content! to the moon and beyond dear Watson!
I just dropped a tear :D
DIY Powermeter is so cool! Insta-subbed. Keep up the good work!!
Thank you so much :D
A yr on and this video is still making me laugh! You're knowledge and teaching ability is second to none mate!
Your soldering skills is amazing!!!
May God bless you son!
i counted you saying "Torque' 33 times
That's a lot of chocolate milk!
@@integza if we do the math, eight 1oz shots = 1 cup, so that's 4 cups = 1 quarter gallon, about 1lb of milk, .45 kg ~ .45 L
@@MrRyanroberson1 i thougth about doing the game with vodka i have laying around but after this comment im glad i missed out on that
You made me realize I underestimated the volume by a factor of 2. 1 pound = 1 pint, so it's more like .96 L
Ryan Roberson that would have been more than I have here at the moment (and that’s good. Nobody needs more alcohol at home at a time)
The most useful video of all time everyone should watch great job
Thank you ;D
Holy crap this channel is awesome! I subscribed after 5 mins watching this video! Keep it up! 👍
5 min? What took you so long?
Thank you :D
Your work is awesome, it deserves much more appreciation. Very funny way to explain science at a high niveau. Even if its not much, i do some promotion for you when i meet my friends.
Alright. I got my glass of milk, turned up the volume, let’s do this!
[edit: Ugh... I give up... this is too much milk for me!]
And too much liquor for me XD
That’s because milk is denser than most other liquids...
works well in betting games
1l milk is not that much for a time i drank 1.5l a day
I have been waiting for this video. It's very interesting and educative.
The song was very funny hahaha.
I was the like 100. I think it's an honor for me hahaha.
Its an honor for me!
Thank you for always commenting and liking the videos.
I can only pray for more subs like you :D
I don't understand how other TH-cam channels, that their content is not as good and dedicated as yours, they have many subscribers. Your channel should be more popular.
Actually I follow you on Instagram😎
@@humbertokokoa11 We will get there soon enough :D
What you made is essentially a small scale dynamometer! Very cool, I could see RC car hobbyist wanting this very thing, just in a slightly different configuration.
Love you channel,if there is anything I can do to help, just let me know!
You make me laugh even though today is a really difficult day for me.
Sorry man
Your weight is swinging. Doesn't this add swing weight?
Same
I’m a year late, but I hope you are feeling better
@Macho Sancho couldn't have said it better myself
What a great channel I found!
Thank you for doing this!
Sorry by my English (Brazil)
Thank you :D
Don't worry, I'm Portuguese, so I'm right there with you on english XD
Hi mate, your content is excellent! Really funny and full of lots of engineering. The way life should be!
Great project! The friction brake using PLA may be problematic, it's friction is likely to vary as it heats up. Closed loop control of the clamping force e.g. a stepper controlled by the arduino could be an interesting development.
You could also try a much simpler way of measuring torque with no load cell required; simply use use a large enough flywheel with known (or measured) moment of inertia, and measure the angular acceleration caused by the motor.
Thank you :D
I actually thought of measuring the angular acceleration and is a great idea but in the end, I opted for a more direct way of measuring it :D
Hello from Germany, i pretty much love your Videos. Please never Stop doing that! And i have a little tip for your Solderskills: If you soldering THT-Parts you have to heat the Board and the Pin at first and after 1-2 seconds you can apply the solderwire. It is also a good idea to use a solder-spnge to hold the Tip clean.
Thank so much for the compliments and tips :D
@@integza Additional tip: There is no such thing as "too much flux"
Also, I love your video, always laughing my butt off and still learning stuff
@@xSchattenfluchx I don't completely agree with you on that. Flux also leaves a dirty surface behind. You can clean it but yeah, if it's not neccesary... :-)
@@integza , your soldering skills are fine but it looks to me like your soldering iron tip sucks, making it difficult to solder well. I use this:
www.amazon.com/X-TRONIC-XTR-4040-XTS-Digital-Soldering-Station/dp/B003TC8EQS
and I love it. It heats up pretty fast (30 seconds, I timed it just now). The tips can take some serious abuse (I have left it on at 320 C for almost a week on accident and the tip was fine), the tips don't erode and they stay tinned nicely over a large area (to me, the tinning on the tip is the biggest factor for nice soldering besides temperature), plus it has a hot-air rework station so that you can solder and desolder BGA, SOT, SOIC, TSSOP, QFN, Etc. IC's and components with multiple tiny pins.
I also highly recommend using water soluble flux, I like to use:
www.amazon.com/Chemtronics-CW8300-Water-Soluble-Dispensing/dp/B0091VQ3U0/ref=sr_1_20?crid=2Z32MTN98X0V3&keywords=water+soluble+soldering+flux&qid=1552184438&s=hi&sprefix=water+soluble+%2Ctools%2C210&sr=1-20
you can clean it off your board with water and a toothbrush, then dry thoroughly with fast air, I have used:
www.amazon.com/XPOWER-Airrow-Multipurpose-Electric-Duster/dp/B07MV1GSTT/ref=sr_1_3?keywords=electric+air+duster&qid=1552184667&s=hi&sr=1-3
or you can use a hairdryer with a reduction or set the drying PCB in a bag of rice/descant for a while.
but for soldering my process is always:
-Clean the soldering iron tip by stabbing a copper scrubby a couple times (scrubby available in the cleaning isle at the supermarket).
-Add a tiny amount of new solder to the tip (for best heat coupling)
-Touch both pad and component with the tip, using the side of the tip that has the most solder hanging on.
-Add more solder on the opposite side using the smallest amount of solder to do the job (I recommend using a small gauge solder wire for more control).
the last step is optional if there is enough solder on the tip, and you are using liquid flux/flux paste. In fact this is how I solder multiple tiny pins on say an SOIC chip. I cover the pins and pads with flux, load up the iron with solder, and then drag the iron across the pins. The surface tension of the solder in the flux keeps the solder from sticking across the pins.
Anyway, your skills are fine, you just need some better equipment, I might have done worse with what you were using.
You need to tin the tip of your iron, which means melt some solder on it first. The liquid solder makes and excellent conductor for the heat to pass from the iron to the part.
You have excellent entertaining and educational videos.
this is one of the best channel on youtube
This is one of my favourite channels
Thank you owais :D
Love your delivery.
Thanks :D
I just love this channel more for every video.
And this channel loves you !
@@integza The TH-cam algorithm gave me something great for once!
Just discovered your channel, great job sir, keep it up!
You just found a new subscriber :)
Thank you and welcome :D
You are an excellent entertainer, sir.
I just found you today. I like your stuff. Keep it up.
Thank you :D
I mean, great video is nothing compare to this!! Not only science and techinolgy!! Very very good :)
Thank you!
Coming from you the compliment means a lot :D
@@integza the compliment is necessary. You make video better than mine, more interactive and funny:) yes I also notice that the power of 38W is alittle bit to large haha;) it shoul burn the friction with the shaft..
@@ATLaboratory To many conversions and I messed it up XD
@@integza haha it happens also to me to say something and let people see somenthing else in the video;) I just post a comment and I pin it at the top
I love this channel it's educational and funny
This guy is multi-talented. Good shows. Well so far I've only watched two of them. We all love Science, and Engineering, and then you present it so entertainingly. Maybe soon you could replace Bill Nye the Science guy. I think he makes a pretty good living down in LA presenting Science to Kids, and Adults.I like the hands on approach. It's cool!!!!!!!!!!1
Adorei o video vou subscrever! Loved your video will subscribe amazing way of teaching science you are very skilled! keep up the good work!
I like when you make stuff. Makers make this channel
Very nicely explained....
I gave up after emptying a can of tea...
THORQUE!
Very smart guy. Most videos cover things I will never ever fully understand.
Love every video I've seen so far.
Soldering skills need some major improvements.
When I first watching this video I could only make it to 5mins before I passed out. With practice and now a fully fledged alcoholic I can now watch it to the end. Yay!!!!
Love that black and blue gingham
science brilliance and comedy .. how can it be that u have only 500k subs?
Inteza keep it coming bro
Dude, totally awesome !
Qué buen canal, saludos desde México. Obrigado!
this channel deserves way more subs :[
love your channel
Had to like, cant argue with that logic
1:54 rewatching this, i think they still use levers. spoons are highly advanced fluid levers with fulcra near the user (usually on another finger)
awesome video bro!!! keep it up!!!!
Thank you Joe :D
Great content and entertaining thanks
automaticly taking Nmm instead of mNm means, you understood math basics :D GJ!
Want the solder to stick to pins better?
1. Lower the soldering iron temperature
2. First heat up BOTH the pad and the pin with the iron, then apply solder
3. Use flux (either solid flux, or paste, whichever You prefer)
Beirão was a really good choice, I recommend.
I was about to say that tiny motor could never reach 38W of power! But you can still power LED's, listen to music, and charge your phone (just very slowly).
A Great way to learn having fun!
Beirão, a marvelous choice.
Well done !!
Gosh I'm so glad I suscribed to your channel!, also, I counted 32 times the word "Torque", I would be very wasted If I drank alcohol
Are you a man or a rat ????
Just kidding. Thank you for subbing :D
Eye de ee, not ed di e ! Brilliant channel and brilliant content ! Well done! Keep it up!,,
Man you are so fun!
Thanks :D
Catchiest song in the world! Now i know what wires i need to use
Fricken got me with the mayonnaise analogy 😂😂
This shows me how much the US education system has failed us because I just learned more in the past 16 minutes than I have in the past 2 years of highschool
Hey! This only tests power for a specific rpm. What you really need to do is to change the clamp strength, and then graph torque vs rpm. Then plot Watts vs rpm, and you will see some kind of a bell curve. This way you not only get the maximum possible power output, but also the required rpm and torque to reach that value. This principle is quite intuitive when you give it some thought: The one extreme is no load and max rpm with, obviously, zero power output, and on the other hand is zero rpm with static torque and also no power output. Somewhere in between is the maximum power output, and I'm pretty sure it will be higher than what you measured in the video. Also ... keep making videos, I sense a glorious future for your channel!
You're 100 % right but I didn't want to overstretch or complicate the video...
Thank you so much for the compliment :D
@@integza is that mean if i plot Torque vs Speed curves with different value of friction for each curve (the value of friction is constant for each curve ), i will get the same result ?
the second question: can i use weight scale instead of load cell and multiply the value with 9.81 to get the force value in Newton ?
THANX
@@SK-we1ty Yes, you can use a scale.
What controls the speed is the level of friction, so you can do it but is a little bit redundant .
Well, I'm impressed...
I really enjoy you channel. It would be interesting if you mounted the motor/generator on bearings and attached the load cell to it. Put a variable resistor in the output circuit and include the arduino as a data logger. Then you would have an electric brake dynamometer.
Keep going with this TH-cam videos and you gonna be successful!
Btw: Tesla is amazing! Could you also do some stuff from DaVinci?
subscribed because of thorque
you are a very entertaining person :)
Thank you :D
Subscribed, buddy!
Great video man 👍
But I still have a doubt on the load cell connections and the lever...like how to efficiently get the rotational force on the lever and to the load cell? Plz help
If I understand it correctly, the dynamic torque meter does the same as the static one, which weighs the hammer on the scale...except that the handle of the hammer slips.
The higher you clamp down (less slippage, aka more brakeage), the slower the motor will go. And that's the relation you measure: rpm at a given brake force.
The brake force is measured by putting the scale under the brake(aka the hammer) - just as with the static setup.
thinking about it even more, you have all the tools necessary to calculate the exact mass of an object using a kibble balance.
Really entertaining style of video! If I may give you one tip on your soldering? Use a smaller tip and 0.5mm solder. Then you can (1) maker sure the soldering tip is touching the pin and the pad, and (2) you can see the solder start by filling up the gap between the pin and the hole, before spreading on to the pad and up the pin :-) Also, use flux!
Thank you for the tips and compliments :D
youre videos are great dude, keep em coming hahahahaha
so funny and informative thank you:)
Licor beirão sem dúvida uma ótima escolha!
I can't believe a video could make me laugh this much times! :-D
I really like this clever idea!
Soldering tip: Heat the whole pin + entire pad both as well as possible, then add solder, stop adding solder and remove the iron. If your joint doesn't turn out as you would've liked it, keep in mind that you need to fully heat the whole joint including solder again. So you can't simply scrape some excess solder off of your joint, because that will result in different layers in your joint which will fail much quicker. (And those fails are VERY shitty because they're really hard to find out about...) :-)
Thank you for that comment an tip Peer :D
Pela garrafa de licor já sei a tua nacionalidade :D continua com o bom trabalho.
The curve at 4:18 actually shows your hammer as quite the average hammer :D
I damn near choked to death watching this video... informative and funny as hell !!!
Excelente vídeo!
Thank you :D
