   John Servo, huh? ?

2. 

   Gud explanation sir but can i use the built in micro servo circuit and connect it to a diy h bridge MOSFETS to drive larger dc motor for a diy large servo? Thank sir…

3. 

   Something I really would want to see is a loop with a incremental incoder.

4. 

   The whine is from it being driven via pwm, and also it being undervolted

   Pretty cool! The larger servos are expensive, I diy what I can. @14:149 The whine is the pwm drive being heard from the motor, if I'm right.

   It's often good to use supersonic PWM frequencies when driving motors so they don't sing.

   I am just trying to get information of how to make an animactronic

   That's awesome bro..thanks for sharing n keep up the good work of doing n sharing ? hope to see some Brushless ones too next time..thanks

   Now that is a big servo.

    Why do you always slam things down on the desk? Slam, slam, slam, slam … what on earth makes you do that lol?
    COmponents shouldn't be treated like that lol – those pins might bend, the PCB might crack … Why would you teach people it's ok to do that?
    Apart from that, great video!!

    Can you make a Freddy fazbear animatronic head

12. 

    We will be waiting for part 2.

    Haha, DJ an overwatch fan? I spot Zarya, Snowball and the OW logo. I also spot Claptrap and the borderlands logo. A 3d printed pokeball, too. What did I miss?

    Great vid, but could you do this with analog? It seems like something that would be overkill even for an 8-bit mcu.

    I've made some giant 7 segment displays for a giant (jumbo) digital clock I'm working on. uses some LED modules with a plastic housing and adhesive backs, have 3 LEDs in a row and have wires on each end arranged as a 7 segment display, I have some various boards for driving them using shift registers and CD4511 BCD – 7 seg decoders and a board that has an RTC and 328p (arduino nano essentially) that will drive the digit board drivers

    How easy would it be to repurpose an electric power steering motor and controller into a servo?

    A remark on your testing. It might have been better to let it keep a horizontal position, and you keep adding water until it can no longer hold (i.e. discover the maximum holding torque). The way testing is done now, is less accurate as well as that the weight swinging around adds so many dynamic factors with peak-loads exceeding far above the average load. These peak loads can wreak havoc on the mechanics, and I expect that these high peak stresses caused the PLA to break (because PLA has no 'give' before its failure point, a high 'hardness'). Also, the servo arm changing position all the time means that the net torque varies a lot because of the force vector of the mass of the load being non perpendicular to the servo arm.
    Of course nylon would be better for the pulleys, and if you have a modified 3D printer it is definitely printable as well.

    The DRV8871 is a champ of a motor driver IC! Nice choice, and great project! I use that little guy all the time! Keep up the great work!

    I wish I have this tools, Great 😉

    Could u guys make an automatic coil winder i think it would be really helpful for the community for winding transformers,rf chokes etc

    Thanks for the build, DJ! Your hard work is well appreciated and I look forward to seeing your next build. I don't personally know DJ and neither am I being paid to say what I say. If you guys haven't watched his animatronics projects with the huge robot in the back corner then you should definitely check it out. I'm going to watch it again soon!

21. 

    Nice

22. 

    Cool

23. 

    Pretty impressive!

24. 

    D.J. well done, that servo is epic!

    If I micro servo can adjust ailerons on RC planes… can ya make it DO AN ALIERON ROLL!!!! ?
