DIY Torquemeter - How to measure torque! [Arduino & 3D Printed]
HTML-код
- Опубликовано: 8 июл 2024
- 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
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.
Your channel deserves to have soooo many more subscribers. Your content is super interesting and original.
Really refreshing tbh ^^
Thank you so much :D
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!!
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 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
The amount of work you put into these videos is great. I appreciate your humor while teaching me new things
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.
Aw man I really enjoy your content, I hope the RUclips algorithm is nice to you and that your channel explodes. Because this is some quality content
Thank you so much for that :D
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.
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
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)
Super stoked that I found your channel. Keep it coming 😉⭐
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 :)
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 RUclips 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
ahh my man. i thoroughly enjoyed this video. i learned a lot and your song is going platinum
Great production values and content, I'm sure more subscribers are on the way!
Thank you :D
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
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
You have such amazing videos that get me inspired to design and create! Much appreciated buddy your doing the world alot of service. 😊
DIY Powermeter is so cool! Insta-subbed. Keep up the good work!!
Thank you so much :D
Very good combination of technical and Comedy : brilliant explanation of static vs dynamic torque
Once again, great content! to the moon and beyond dear Watson!
I just dropped a tear :D
Thanks so much for sharing your model! Awesome work getting this working.
Thank you for that comment :D
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 are a such a talent man. You should have millions subscribers.
Your content are incredible valuable and very entertaining
Thank you very much!
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!
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
Your videos are interesting AND FUNNY. New level in making science and technology closer to ordinary people. LIKE :)
The most useful video of all time everyone should watch great job
Thank you ;D
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
Just discovered your channel, great job sir, keep it up!
You just found a new subscriber :)
Thank you and welcome :D
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
Love your delivery.
Thanks :D
This is one of my favourite channels
Thank you owais :D
I gave up after emptying a can of tea...
THORQUE!
Very nicely explained....
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 :)
Well done !!
You have excellent entertaining and educational videos.
Inteza keep it coming bro
awesome video bro!!! keep it up!!!!
Thank you Joe :D
I just love this channel more for every video.
And this channel loves you !
@@integza The RUclips algorithm gave me something great for once!
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
Hi mate, your content is excellent! Really funny and full of lots of engineering. The way life should be!
Great content and entertaining thanks
Dude, totally awesome !
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.
love your channel
Your soldering skills is amazing!!!
May God bless you son!
this is one of the best channel on youtube
I just found you today. I like your stuff. Keep it up.
Thank you :D
I love this channel it's educational and funny
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.
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.
You are an excellent entertainer, sir.
Subscribed, buddy!
A yr on and this video is still making me laugh! You're knowledge and teaching ability is second to none mate!
Beirão, a marvelous choice.
Adorei o video vou subscrever! Loved your video will subscribe amazing way of teaching science you are very skilled! keep up the good work!
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!
Fricken got me with the mayonnaise analogy 😂😂
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)
youre videos are great dude, keep em coming hahahahaha
Had to like, cant argue with that logic
Qué buen canal, saludos desde México. Obrigado!
Man you are so fun!
Thanks :D
A Great way to learn having fun!
so funny and informative thank you:)
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
I like when you make stuff. Makers make this channel
you are a very entertaining person :)
Thank you :D
Well, I'm impressed...
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)
Love that black and blue gingham
Excelente vídeo!
Thank you :D
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!!!!
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
this channel deserves way more subs :[
I damn near choked to death watching this video... informative and funny as hell !!!
Thank you so much !!!
Catchiest song in the world! Now i know what wires i need to use
Eye de ee, not ed di e ! Brilliant channel and brilliant content ! Well done! Keep it up!,,
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
Keep going with this RUclips videos and you gonna be successful!
Btw: Tesla is amazing! Could you also do some stuff from DaVinci?
I have a question. Won't the friction clamp stop the shaft from rotating? How tight is the clamp clamped on the shaft?
What did he take the length as? Length of the entire clamp and distance between the shaft center to the point where the clamp touches the load cell
Licor beirão sem dúvida uma ótima escolha!
subscribed because of 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.
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
Cam you help me with the setup..like how is thorque mounted on the shaft of the motor?
I'm trying to recreate this as a personal project, in your code there is "float arm = (28);", does this mean the torque arm is 28mm in length?
Also, is there a way to not measure maximum but just constantly monitor both rpm and torque values?
Very glad I found this channel. See what happens when you google Tesla coils after smoking?! Lol
Great work!!
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).
science brilliance and comedy .. how can it be that u have only 500k subs?
Hey there...quick question:
In the sketch you simply calculate torque as (force * arm),
but where do you account for a friction coefficient between the shaft and the lever?
Otherwise you are just calucating the reduced torque transferred to the lever but not the real torque on the turbine shaft.
Using different materials for the shaft interface, you would certainly get different friction coefficients and thus different force readings.
How did you calibrate this friction coefficient?
No need for friction coefficient.
Part of the torque is removed by the lever and the other is used to accelerate the axis.
Because we know both the torque removed and the speed of the axis, we know the total torque.
Also, this is a DIY project to measure only the dynamic torque and not an industrial level device.
@@integza I have to think about this some more :D had the idea of implementing a simple torque sensor of this type in my Thesis, maybe I'll be back with another question ;)
Oh please make more of this "Tutorials" (I don't mean the drinking part) ;-) I like your channel!
Thank you :D
Pela garrafa de licor já sei a tua nacionalidade :D continua com o bom trabalho.
Can anyone explain how the load cell is used to measure the torque on the measuring tool. Thank You
