@@netroy Pololu sells geared DC motors of all sizes and torque requirements. Not to mention continuous rotation servos are also sold. Why spend the money on a servo only to remove features that make it the servo in the first place?
This was great! Thanks for this.. Quick tip for those doing it.. use a servo tester and set to neutral. This is easier than trying to find the neutral point with a screw driver. But if you don't have one; the screw driver will do it. I did the first one with the screw driver. I did the rest with the servo test. set to neutral, pull the pin, cut, put back in; done!
Nice. But you have to mention that there is no more 0 positioning feature. Which is not a problem but something you need to keep in mind depending on what you build.
I can see 2 solutions ,one is to integrate a multi turn potentiometer they are generally 10 turns . the other solution is to use an absolute encoder (AS5600) coupled with a counter (ATtiny85) to generate a pwm voltage then you may program the full tension for 5 turns or 100 turns (obviously the precision of the positioning will be less accurate with 100 turns than 5 but you will have a real servo
Thank you very much, but I want the servo to rotate 359 degrees and then stop, or to rotate ±179 degrees. In the scenario you described, the servo rotates continuously without stopping at 360 degrees.
wait so to control the number of rotations (say number of 360 rotations) you would just write it as a large value? for example if I want it to do 4 full rotations. It would be servo.write(1440)? I am going to test it myself right now, just wondering how you did it. :) great job!
The potentiometer is for keeping center. The shaft rotates the potentiometer, so the servo IC can control the motor to go back to 0 after a pwm command. If you just cut the shaft, the potentiometer might also drift over time. Centering it with a servo tester or reciever while you glue the potentiometer makes sure it won't have an offset. If it does have an offset, trimming the channel can fix that.
I’m try this out. I did this few months ago before finding out this video exist and I ended up taking the potentiometer out and it just kept spinning in one direction, couldn’t control it or anything lol 😂 but now I see this video ima try it again
Superglue, CA glue. And it seems like a dremel or other cutting tool. Also, the endstop might just be pressed in there, and you can sometimes pull it out instead of grinding it off.
Awesome video man, I've a bunch of servos I need multiple rotations on that this'll help for. One question though, if you have a force acting against the (modified) servo, like the crane you showed at the end there, what's to stop the servo /pulley from unwinding? Is it just the internal resistance of the gearing? Great job!
so my servo started doing this on its own like i didnt do anything to it and now when i plug it in it just constantly rotates counter clockwise any ideas on how to fix?
You striped a servo gear. You will need a new servo the only way to fix it is if you have an extra servo that is the same brand and size that you can take the gears out of to put into your bad servo. In most cases it just means you need a new servo. If the servo has a lot of stress on it you can try and change it out for a metal gear servo to prevent plastic gears from striping out. It will add a bit of weight to change to metal gear servo. Cheers
eu quero fazer o contrario, quero usar na direcao do meu modelo porem o meu fica girando , girando, e girando, arrff, como resolvo isso? quero colocar para girar para uso na direção sem rotacao 360
I am confused as to how this works. The potentiometer is the thing that tells the microcontroller where the the top this is and makes shure that it stays there so by doing this you basically just created a high twork motor
Yes, that is basically what servo testers do. They usa a potentiometer (variable resistor) to position the servo. So, if you want to control the position of the servo with individual resistors you could use a servo tester, measure the resistances of the potentiometer positions when they are where you want them, desolder the potentiometer, and use something like a dpdt switch in addition to the correct resistor values to mimic the potentiometer being there
Aff.. This is just destroying the servo by removing the feedback.. Now its just a dc motor with a gearbox. Idk why you disconnect the pot when you could still use the positioning at 360 deg. Now, how is it going to hold positions? Also..Every servo isnt the same. Not even all Rc servos. 😢
Right to the point with no nonsense beginning or ending video and music. This is how instructional videos should be made! Thanks a ton!!!
yeah, nowadays videos filled nonsense music and useless speeching...
This is how to turn a servo into a DC motor
geared DC motor. for that sweet sweet torque.

Turing servo with positioner into just dc motor with gear box ... which you could by easily from the very beginning. Great!
THIS is how you make a clear and concise video!
Except the title is BS
Wait a no bs youtube tutorial? FREAKING THANK YOU MAN
This is not a 360 mod, it is a continuous rotation mod.
stay mad buddy
@@DaltonAaker the sensor is not working
well he sayed it right... its tutorial how to make HIGH TORQUE MOTOR@@DaltonAaker
congrats, you turned a servo into a stepper
I did the same thing with a few serves as well a while back. It's quite useful
Nice. But you have to mention that there is no more 0 positioning feature. Which is not a problem but something you need to keep in mind depending on what you build.
Wow this is great! I got some good ideas for this!! 👍🏼👍🏼
Thank you ! Great tip.
But it's also not a servo anymore, right? It's a DC gear motor.
Precisely, might as well have used a regular DC motor and attached a gearbox to it.
@@TheCyberSpidey ya , but the torque is much greater than regular motor . and weight is less

Thanks - Was helpfull to see how a servo angle limit can be removed.
Help a lot! thanks
Can u please do a video on this exact servo for reversing, how do I do it? 🙏🏽
Thank you very much, but I want the servo to rotate 359 degrees and then stop, or to rotate ±179 degrees. In the scenario you described, the servo rotates continuously without stopping at 360 degrees.
Thanks for the video!
I know this is an old video but if you are around, can I still control the degrees of throw in the servo? Thank you in advance.
I think that no. You know the answer to your question now?. I have the same question
@@gretyprieto9463I think that’s when the 360 degree servo motor comes into the play. It’s different from the 180 product shown in the video.
It can be used for dropping something.Thx
Is it possible to control the speed?
wait so to control the number of rotations (say number of 360 rotations) you would just write it as a large value? for example if I want it to do 4 full rotations. It would be servo.write(1440)? I am going to test it myself right now, just wondering how you did it. :) great job!
With this method, I am not programming a certain number of turns in the servo, just turning it off or on.
Did it worked?
how to make them from 360 to 180°?
Will this work if you just need more travel on the servi
No it will not but you can usually make more travel on the controller you can make it move like 120 percent rather than 100
wait but does the positional sensing still work and can I increment the motor by the same step per rotation?
Ffriggn Awsum Job !!! 😉😎
I seen a bunch of this mod how tos. So my question is why do you have to glue potentiometer and cut the one shaft?
The potentiometer is for keeping center. The shaft rotates the potentiometer, so the servo IC can control the motor to go back to 0 after a pwm command. If you just cut the shaft, the potentiometer might also drift over time. Centering it with a servo tester or reciever while you glue the potentiometer makes sure it won't have an offset. If it does have an offset, trimming the channel can fix that.

It's possible to reduce speed then on ? and of course more or minus speed
I’m try this out. I did this few months ago before finding out this video exist and I ended up taking the potentiometer out and it just kept spinning in one direction, couldn’t control it or anything lol 😂 but now I see this video ima try it again
And does still PID after the modification?
I did this exact mod to my servo, but the servo slows down to a crawl after a couple of seconds. Why does this happen?
What are the material is used to make the servos hold, glue of some sort and what kind of a machine is that to cut up the gears ⚙️……
Superglue, CA glue. And it seems like a dremel or other cutting tool. Also, the endstop might just be pressed in there, and you can sometimes pull it out instead of grinding it off.

what is that wire you use with the rv?
Thank you for this short info video, however my servo rotated 360 by just cutting the gear part
Hello does this have enough power to push a parfum bottle to spray thé fragrance out ?
Excellent tip!!! That maybe the best how to in a long time!! Thank you..

Just to clarify there is no longer any position control after this modification correct?
Correct

sorry to ask but wouldn't the servo lose its accuracy
Is there a way to decrease from 180 rotation to 90 rotation on RC servo using resistors
Yes, that is basically what servo testers do. They usa a potentiometer (variable resistor) to position the servo. So, if you want to control the position of the servo with individual resistors you could use a servo tester, measure the resistances of the potentiometer positions when they are where you want them, desolder the potentiometer, and use something like a dpdt switch in addition to the correct resistor values to mimic the potentiometer being there
How do i rotate it in the opposite direction using arduino
To make it reversed you can adjust that by making the servo revers on your controller.
Just curious as to why they don't make some servos like this?
They do. They’re called continuous servos.
Also known as: Gear Motors. He simply took the servo out of the servo motor.
is it possible to just cut the stop? What would happen then
It would turn over 270-ish degrees before wrecking the feedback potentiometer.
Why not just use a continuous servo or a motor?
But i need to Concerto 360 to 180
Rip dc gear motors🤔
very very easy and fast huh
but it disables the main function of a servo
What if you want a winch or a motor for a robot?
So now it is a motor 😂
Why don't you just use DC motor?
That isn't a servo anymore. That is a DC motor.
Why don't they just sell them like this?
Because most of the time, it then doesn't work the way it was meant to. For example RC airplane flaps only need a bit of rotation, not the full 360.
@@Mediamarked That makes so much sense thank you!
They do. Its called a "Gear Motor".
You mean 180° to 360° ?
it just spins in one direction
No it changes direction and stops you can see in the video I use the switch to change directions it is spinning.
Now you have unprecise serve which doesn't know how much it rotated
yes exactly it just spins 360 degree
But . . . Why ? You can already buy the 360 degree version of a servo at the same price as the basic servo !
You just get... continuous servos!
u just converted a servo motor into a cheap gear motor .
umm you just made it a motor
thanks for info 👍👍👍👍👍👍👍🇲🇾🇲🇾🇲🇾🇲🇾#FYP
Damn it literally only rotates 90 degrees huh? why did they do that I wonder
So in this tutorial we will be striping what makes a servo a servo and make it a DC motor
I'm jk man great vidio tho
You need a more expressive voice synthesiser
there are 360 servo... modding is just a waste of time if you don't plan ahead
It stops being a servo, you know
True
no mate! that is not 360... its continues in both directions!
now make 360 to 180
