Can't wait for 2022 finale
Me neither ;-)
Anthony Pinto I keep asking myself that.. 😎😎
me too
Polkacik I wonder where it'll be hosted as TH-cam will be a Pop Advertising Click Bait wasteland by then
I cant understand what hes saying ( Im deaf, with hearing aid, hard of hearing) what did he say about 2022 finale
I like that you explain how the individual components work in detail and not just what they do, can be difficult to visualise from a datasheet sometimes. Waiting for part 2 :)
Do you feel like a man
When you push her around
Do u feel better now
As she falls to the ground 🗿
This is the kind of content the internet was made for. Thank you so much for posting all these great videos. You are a great teacher to us less knowledgeable tinkerers. I love your content. And I would like to say also, your english is very clear and very good. I am glad to have your channel in my sub. list.
I just watched your "Make your own time machine" video. It worked like a charm :D
You should make scans of your wiring diagrams. It's art, man!
I love your hand drawn schematics. You should sell them as art. Freaking gorgeous.
Neato Electro truly
on art world no need to be smart but just sensitive, you underrate an engineer
Thank you for making this series! I've showered the internet for such a video several times
Great Scott, great job, I admire your determination to accomplish the Quadcopter project !
Do you keep your drawings and schematics? Your handwriting is beautiful and very clean. I'm not sure if you've ever considered scanning them for a pdf download but that would be really cool to have. Thanks for the great content
Looking forward to seeing the quadcopter finished this year 🙂
great! i have searching this on internet but you made it. thanks for the video, its helping me to understand a little bldc works.
Me watching this in 2023..
Same
Lol were right on time
Hmm
Welcome in 2024
Me in 2024 😂
Yeah! i knowed that will be something with motors his week :D
thank u very much to make a video on esc, i like u r videos
Every time I hear your intro music I cant help but think of the Mr Wizard tv show I grew up watching as a kid.
When you make video, it's always some Boom....
Keep on doing the projects and you'll make world more interesting place..
I'm curious about holding current from the ESC for an application when you want to hold the motor still under varying load
I once programmed an Arduino to function as a very basic ESC. It couldn't start the Motor on it's own and changing the motor speed while the motor was spinning caused the motor to stop. But as long as you start the motor by hand and don't change the speed, it works.
That was for a school project where we were supposed to build a DC motor, while many failed, and some didn't really fulfill the task, I had to overdone it ^^'
Neat. The issue is fidning motor position.
You can use the voltage created in the coils, but it won't do the start so you will have to step it up to run-able speed.
The other common option is having sensors in the motor to tell the position, and use them to determine what step to use.
Chickenbread Designs did you use a different power source and a mosfet switch?
Hey Great Scott. Only a few months left for 2022 to complete your quadcopter!
Thank you. I couldn't find any video in TH-cam where we can make our own esc. thank you very much
wow this is amazing and you are so smart
I used to watch GreatScott before i started droning with you Stu.😉
I'm not entirely sure that this is how a sensorless brushless ESC works. Commercial units read the back-EMF induced in each of the coils to determine the position of the rotor and turn on the correct phases. Speed control is achieved via PWM modulation of such phases and not by arbitrarily speeding up the phase switching.
Thanks for explaining in detail whats under the hood!! Love it!
Great Work Scott , I´ve been trying to make an arduino ESC controller for a couple of years!! This help me a lot! THX
Part 3 flying of quad quapter
Great Video! you can even 3d print a frame instead of using wood also would you please condider talking about SimonK firmware, BLHeli Firmware and other popular firmwares for ESCs? im constantly burning my escs , my guess is the BEC is causing some kind of short within the ESC and burning it, but this is a great video eagerly looking forward to the second part!
How much current are you using? How big is the filter cap on the ESC?
Well, what is burning? The BEC supply and rest of the ESC are typically separate circuits. There is usually a separate regulator for the microcontroller, which is sometimes shared with the relatively low current gate drive supply where applicable. FET failures can happen for all sorts of reasons (external oscillator stopping from moisture, excessive body diode conduction, no external pull-offs to deal with MCU resets, etc), many of which can be secondary failures.
You probably need higher Amperage ESCs
Thank you guys for the suggestions I should have given a little more information, so I use the cc3d FC, best way to power it is with ESC via BEC, the ESCs are 30A SimonK and the battery is 3s lipo 3000mah 35c, everytime the ESC with which I power the quad blows out (in my case ESC 1,which is front left in an X configuration quad) I dunno what to do, I will try to order a new batch of ESCs and then supplying power to FC via PDB directly (my PDB has a voltage converter IC on board), hoping this to solve the problem, as other wise when I opened the ESC only 1 MOSFET was burned, this could have been the voltage convertor or BEC too, as it's burned so badly I can't read what's written on the package.
Afzal Patil what amperage are your ECSs and what motors?
their polished surface looks so satisfying
Great video, thanks for sharing, my recommendation you do need create with the resistor network one sensorless method for know the position of your motor and applied the current in the correct moment for increased the speed and performance of your driver.
Great Scott, can you make a video about AC motors or the difference between AC and DC motors please?
There are tons of videos out there explaining the difference between the two.
Petru Sfecles, yeah but GreatScott man.....
The gist of the difference is simple. A DC motor is just an AC motor with a controller/commutator.
In other words all motors are AC internally in the sense that without a changing field it's impossible to create motion.
All motors work from AC.
Scott please make an air conditioner (not a swamp cooler).
Cool & Quiet ... the reality is they are much different.
You are the best... and I don't give complements easily. Subscribed !!!
Awesome, and awesome channel in general (long time follower), but would love more of this.
your quadrocopter will still be finished before the airport BER (Berlin Brandenburg) haha
Good one :-)
Hi grear scott
Hugs from mex
@@greatscottlab HEY MAN I GOT BRUSHLESS MOTOR WITH 14 MAGNETS FOR MY LONGBOARD AND WHAT CIRCUIT SHOILD I USE FOR WIRED REMOTE CONTROL ???
On which software do you simulate the circuit?
Im rewatching these vids since I have a 12 DC Volt frigde, and for what I can see the compressor is a BLDC compressor so Im gonna try to make a control board that control the compressor's speed acording to the temperarute, thank you for the well imformative video!
oh man this was a tough one.......darn phases! I need to watch this a couple of times
Do yourself a favour...
Buy a fountain pen and fill it with red ink. It will be more cost effective/environmentally friendly then using hundreds of throw-away pens per episode xD. It will also look awesome in the drawing shots of your video!
Keep up the great work!
Who else wants bootstrapping basics?
Me!
Kau Mohlamonyane ido
Me!
What is bootstrapping? I'm asking serious. Explain this to me like I'm a total noob plz.
Still waiting on an explanation
I love the frequency of 20 milliseconds. It's the perfect rotational speed.
Great Scott. Finish it quickly. look up "ardupilot". I'm working with it and made mine with less efforts. So far made 2 quad copters. I recommend you get an external compass for ardupilot to minimize noise from ESCs.
I watch all your videos. awesome work man 👍
i like variable resistors
same thing, just different shape
when I read the title I thought this was actually a guide to macbook "pro" owners to make their own physical Escape key
hehehehe
Finally a tutorial I've been waiting for.. But until now I somehow managed to save money to buy a new one.
Can you make a video on what parts you always keep on hand?
PS. I think you should chose a different material for your qaudcopter like metal mesh because the wood prevents airflow therefore adding more wind resistance.
1:36 frequency of 20 milliseconds?
Yeah with a period of 50hz
Wow,
Nice to see a TH-camr that responds to comments
Very interesting and well explained, looking forward to part 2
how can I use this steps to do an esc to work with 48V and 1500w?
if anybody know please help me
I wanna know too
I'm in for a 48v 750W +/-
What is Bootstrap?
Bootstrapping is a method to drive high side n-channel MOSFETs. I might do a video about it in the future.
I second this question.
please do :) you explain stuff very well. so would be much appreciated.
In a nutshell, when we talk about MOSFET transistors it's a technique to obtain a higher voltage level than your supply voltage. In order to correctly drive the gate of a N channel MOSFET placed in a high side topology you will need to provide a gate drive higher than supply voltage.
Petru Sfecles ohh ok. That makes what he was saying make sense in a way. Thanks.
I'm more of a computer guy so my first thoughts were total confusion xD
Hey your explanation is better than any school teacher I've ever seen. New here.
+GreatScott! thank you very much for this! It is exactly what I asked you a few weeks ago, and here it is! Hope it will be helpful for tons of other people!
laughed so hard at 0:07
Yeah "probably"!
it's a joke lol
Well the joke is getting serious..... Its soon 2022
HOLY CRAP! You have a $10,000 Oscilloscope?
It's just a hobby scope you know. Just like Great Scott tries to make you think it is. But he has extreme good gear for just a "hobby".
Nice project!! I look forward to part two.
I really enjoyed this more practical video, the last two videos were to theoretical for my taste. Please do some more of this kind.
2021 and counting.
lol phantom props
Cool, nice to see how that works, looking forward to #2 :)
Very cool ! Someday I hope to have a better understanding of electronics so I can do something like this off the cuff.
This project is waaaaaaaaaay beyond my brains.
MrRCking84 That's fine, it's all about learning and that doesn't happen instantly. If you just need a good ESC, they are under $5 for a 30 amp speed controller. I'm not an expert on it either, but I like learning about it.
Jake Garrett But you are good at what you are doing.
wait is it possible to create an esc without arduino?
i mean well i do have arduino but i dont understand much of it
so there should be second option to create an esc without a arduino, right
It is possible to do without Arduino, but I think using a µC is the easier way to create one.
Logic gates and shift register?...
I have driven stepper motors with an ULN2008, 4017, a few diodes and NE555 before. It should be possible do to the same with a BLDC Motor.
You don't use sine with a BLDC. Only PMSM need sine waves; BLDCs use 120° shifted 0 -1 0 1 (stair?) waves
Also called block-commutation.
awesome video as always! eagerly waiting for part 2
I love watching your videos, I don't have a clue on alot of what your saying but I do learn some.
It's actually "Electronic Speed Controller"
Actually some people say electronic, others electric. Doesn't matter.
I have to agree with Francis.
GreatScott! If one would want to nitpick electronic would be a little more correct. I guess it's the same like the difference between electrical and electronic engineering. Electronics is more about the working of the semiconductors, controllers,... And electrical more about power distribution, high voltage, etc. Not that they both don't have an overlap. But there is a difference, albeit a small one.
Not that it actually matters that much.
Electronic engineering is a subset of Electrical engineering. Electrical engineering is the BSc that you get from university, and you may specialize into electronics/power/communications/EM/nano/etc.
Francis Rohan John 😂😂😂your that one guy. Who just had to day it🤣
Am i first??
Keep the good work up!
Yaaay a quadcopter in 2022 really like your videos and waiting for 2022 thanks for content
Thanks for your explanation!!!you are a genius i follow all your videos.
Me watching this in 2024..
Same
1:36 frequency of 20 ms?
"cycle duration"
yep, I knew that but I wanted to point that mistake out :)
Or period?
it was not a major mistake. you know what he meant
maks886, to the technical community who can understand the main point, you're the equivalent of a grammer Nazi
I have been waiting for this video, Thanks!!
You taught us a lot of new things, thank you
Who noticed he never shows his face on his videos?
You need to watch more GreatScott!'s videos.
Been looking for a video like this for ages.
Nice analysis..... Excited for the next part.
Cool project, Joop Brokking did make his very own flightcontroler for multiroters driven by the arduino
Henkel gezwenkel everything is becoming diy these days .You can make your frame (3d printing) ,your radio(opentx mega,nextsteprc),flight controller (joop brokking,multiwi etc),ESC as this one and in another channel I have seen.someone even created his own 3d printed motor(halbatch or something like that).wow really wow
hey man 2022 is pretty close , can't wait
I dont understand the programming but I m glad I watch your video. yet still I dont understand. I love your videossss
Hey mr great Scott. Beautiful wrk.
By far your best video. Thanks.
Absolutely brilliant mate, loved this video. So informative.
Thank you for sharing.
👍👍👍👍👍THUMBS UP👍👍👍👍👍
Subscribed 👍😁
I'm always hesitant to open one of your new videos, every time I do open it up I know I'll end up spending the next 5 hours on a new project. Was würde ich ohne dich tun? Lol
What program do you use for prototyping your circuits?
Thanks, your videos are great!
I really like your video good job continue bro
great vid scott!
Thanks man it really very helpful to my project keep post BLDC related videos👍
Great! You have amazing pedagogy.
If you use two seperate power supplies(your supply has two channels obviously) It may work.just an idea.great video greatscott !
I remember asking about this a while back. Glade to see it here,
I found your channel the best
So clever the whole lot, EG sourcing the IC ,etc.
Thank you for sharing your knowledge.
Great! I was looking forward for some more info aboud BLDC and ESC because your last video about it was pretty general and don't include many interesting things. Thanks!
One of the best TH-cam channel
Such an awesome channel!
Had a class professor could explain in such a way!!!
Waw, this is a very interesting video ! Congratz !
It's 3/4 quarter of 2019 already. Can't wait for 2022.
I needed this video! Got my Sub.
Great start Scott, but what you are implementing is open loop commutation which is very inefficient. I hope you can reveal the secret of sensorless commutation feedback which allows variable power with best efficiency, so critical for battery operated drone flight.
