- čas přidán 30. 06. 2024
- Hey everyone! Today i'll be showing you how to modify or "Hotwire" a small Miscro Servo to run on simple DC battery power! No Programming or Coding or Microcontrollers reuqired!
Why do this you ask?
When starting a hobby that uses small servos like robotics or in my case; Cosplay and making Iron Man helmets that open and close with buttons, this step can be very overwhelming.
I know when i started out the prospect of codes and arduinos and microcontrollers scared me!
Having a strong background in DC 12V systems i knew there must be a way.
Sadly most tutorials out there werent that great and were hard to relate to what i needed it for.
So i figured it out and made this tutorial for you all to enjoy! I really hope it helps! It's a great way to start with automation of parts and projects without having to worry about coding.
The Servo can be easily swapped out later if you choose to upgrade and start really getting fancy!

Cool. Coding is not necessary for many on/off things. Just like an old school electromechanical pinball machine. Bumper switches, limit switches, solenoids and DC motors.
Finally what I was actually looking for. I see so many tutorials that use Arduinos and I just don't have the skills for that yet, since this is the first time I'll ever use servos and I only want to do something pretty simple like what you did. Thank you so much!!
The knot is a good idea for any project you don't want wires getting pulled out, good idea
Thanks man. I also replied to the other comment
what u also could do is use a servo tester, it has a knob u can turn and the servo takes the position u turn the knob, it is also very cheap and requires no programming, just putting it out here
But can you use it for two servos
Or will I have to use two testers
You can connect up to 3 servos to most testers
Never thought about servos out of Arduino context. Great eye opening tutorial!
I wish I came across your channel sooner. I can’t stop clicking on your videos because they all have tips I need for a lot of different projects that I have going. You’re very resourceful and good at explaining. Keep up the awesome work!
Thanks so much!
After watching this, I know it’s a W for my final year project. Thanks so much man💪🏿
THAT was a great video! I never DREAMED I could do anything like that, but you made it look so damn easy! Step-by-step! Thanks dude!!!
Getting Fit at 50 anytime!
Awesome video! Seeing this has given me further inspiration for a few of my own projects.
Samuel Wicklund that’s exactly the point !
Thank You Frankly Built! I wanted to be able to throw switches on my G scale outdoor layout when I'm done building it. It was either pneumatic, (which is still an option I'm contemplating) or the servos. I knew there was a way to move the servos without having to program them and You have the answer. I asked the question about another way to operate the servos I was looking at on amzon without using a transmitter, and all the knuckleheaded answers said there wasn't. Thank You again.
This helped so much. The amount of projects I’m going to do with this. I am Inevitable. Sliding Door here I come!
Awesome video! I wish I would have found it a week sooner as I just got my helmet mechanism working using a microcontroller and struggled with the code for awhile. I appreciate the detail you go into and the camera angle makes it easy to tell what you’re working on. I didn’t even think of using limiter switches along with this. Looking forward to future videos and I’ll have to try this out on my next helmet.
Paul T hey thanks man! I appreciate that a lot!
Frankly Built Sure thing! The rest of the suit looks great too of course! My MK VII was also almost entirely 3D printed so I appreciate all the sanding and finishing you went through to get your final result!
Thanks for this tutorial frank. This really help me with my RC car project.
OH MY GOSH THANK GOODNESS I FOUND THIS VIDEO!!!!! A MONEY, TIME, AND ENERGY SAVER ALL THE WAY!!!!
Another question well answered :) thanks again Bud great work
LOVE IT! I'm probably gonna skip right to arduino but this is great for testing!
Holy crap... you just solved all my problems!
This is amazing! Defo gonna use this tutorial to make moving spiderman lenses
Thanks for posting this video. Totally helped
OH MY GOD THANK YOU, I feel like programming would be too hard for me just to move a servomotor for my cosplay, this is way easier!
Love this video!!😘😍
I’ve managed to rig up an accelerometer to my servo. I’ve got it set so that when I nod my head upwards, the accelerometer (once it hits the threshold) will tell the servo to “open” the face plate. Then it does the reverse when I nod my head downwards, closing the faceplate. I just need to 3D model some brackets up for the servo and faceplate to connect them.
Thanks .. exactly what i needed for the garage door of my vacuum cleaner robot 🤖
I'm trying to get my mask to open and close with a switch under the chin, this video is a great start!
Just the info required for my project thanks
You need a bit of coding to use the servo in a “proportional” way. But this excellent hack is good for “bang-bang” (to the limits of each direction of rotation). Thank you
Bro thank you 🙏🏻!!!!!!!!!
This has been a huge help! I'm working on a character with opening face plates and was so intimidated by the advanced stuff of programming the servos. While I can now hillbilly rig my servos (🤣), how would I connect it to a power source and switch to activate them? Do you have a video on these ideas too?
Hola a todos, me gusta mucho tus explicaciones con lo que, con ellas, tengo salidas para los proyectos que tengo en mente . digo lo mismo es un trabajo impresionante lo que haces y lo facil que es seguirte, aunque es en ingles, el cual no entiendo. gracias por todo
Great video
you exposed the mystery of servos.
This is brilliant, and somehow in 2 minutes you have explained soldering better than any of my electrical engineering teachers.
LOL no way hahaha
@@FranklyBuilt To be fair, those classes were FAR beyond my understanding and I quickly changed my major to computer networking, but seriously nobody ever explained that the point was to heat the wire and have its borrowed heat melt the solder.
Oh well yeah. How else would it work haha that makes sense tho. Glad I could help!
Frankly Built for the longest time, I failed at soldering because I let the solder melt all over the irons too then touched it to what I wanted the solder to ultimately join. It....didn’t work very well.
Mason Luxenberg I used to do the same thing haha. Wait till I make a video about pre-soldering wires to attach them to small boards and junctions! Your brain will melt
Awesome!
did you ever do a follow up video on how to add the on/off switch? great video by the way!
This is what I am looking for! How did he reverse the direction of the servo without just flipping the battery poles? Please let us know if you find out how, thanks!
Having a servo hit the stops at full speed WILL strip the gears. You can also take the potentiometer out and the stop pin, so you have a gear motor that can turn in either direction without stopping. Check out "continuous rotation servo". More useful than this...
Thanks man! Appreciate the input
Thank you!
Finally this is what I want to do with my Ghostbusters pke meter prop
Nice!
HAND ALL BURNT: “I’m comfortable with my soldering skills”
Just joking!! Thank you for the great video and all smart tips given!!
Very nice video. Is there a way to wire it so the helmet stays open the the room light comes on and closes when you turn off the lights. I'm assuming you can use a photocell to make it go one direction,(90 deg), but how do you make it go back when the lights change? Thank you for your thoughts and video
I like your idea of using the servos without a controller. I want to use one to raise the tonearm on the turntables that I build. You spoke of circuitry to prevent the full stops from reaching their limit. Did you ever do a video on this?
+1 for this follow up video
@johnlake6321 did you ever figure out how to their full stops from reaching their limits?
Great video. I am totally ignorant to arduino and servos but I understand that what I want to do can only but done with these units. I want to lift a top ( square wood top) from the four corners top up 5 or 6 inches. What do I need? What do I need to learn and where? Thanks for your time
Nice video! Does the motor shaft keep stiff when it's not powered?
Thanks you
Could you show the circuitry from the servo motor to the on off on switch? Have a difficult time making it spin in both directs
hello Franklin it would be interesting a video on how you put the hooks to hold on the armor😁✌🏼
Gio Gio it’s one work!
following...
new sub great vid brother. any way I can reach out to you privately? No BS, No games and got No problems paying you for your time and help. thanks man blessed be... ps just seen another video that you don't even gotta take apart the servo and use the all 3 wires as is. you don't gotta cut anything either, you can just run 2 jumper wires right to the motor and still leave the servo wires and board as is and use them later with no damage done.
I have a question, im new to this whole thing and I'm trying to use servos for some wings. Is there a way to slow down the servo and to reverse one of them using this method? Also, how did you attach the switch and can I use a different switch or button?
Plz give the link for the 2nd tutorial i.e to add switch and control its movement
what is the switch you used can you make also some tutorial thanks
Would love to see how you use it with a switch . I want to do this with model railroad turnouts .
Sir, will they work on three servos at a time with only 1 charger ?
Can this same process also be done with 6volt or 12volt servos as well? Im working on a project that i will be using two 12 volt servos that have to work in sync with one another using the same exact switch that you used in your video. I would gladly appreciate your feedback and thank you for your awesome content from your videos!
Cool so easy part is done. How do you wire it so it starts and stops.?!
Fantastic clip
Im trying to build a g seat for a flight sim
I need to operate a servo by a push to make switch then when the switch is not pushed the servo returns ,can you please help ?
Thanks
Dave from Scotland
Do you have a tutorial/video for opening and closing with switches in fingers? As I saw a quick clip pop up near the end and it was exactly what I was looking at doing but can't find a video of it anywhere? Lovely work btw
Not yet but soon
@@FranklyBuilt I eagerly await that video, just finished making my hands. May be a bit small but sure I can make it work. Electrics are my concern and so glad I found your channel :)
Also may be a stupid question but does it matter what wire you use for electrics as I have found 20m of red and black pvc and says max current 1.4amp. Is that enough to use on whole suit? Probably just going to wire each light to individual batterys throughout the entire suit
Possibly a stupid question but the wires on my servos are copper in colour. Does that matter? Great videos by the way.
Hey Frank, What power source would you recommend for this. I was thinking AAA battery(s) or AA
That works fine! I have a new live stream talking about electronics for newbs
hello, Does this servo stop when it hits the turn limit or will it keep trying to run and burn up motor ?
hi man, you have a link for this motor? where is possible buy the motor in this video? :)
Thank you for the video.Do you have the video using the Reed switches posted? Thank you
shellumus working on one soon
@@FranklyBuilt thank you
Please can u do a video on how to wire up different switches like the 3 prong rocket swich or one for just different types of switches please thank you 👍
Actually you can remove the rotary encoder also to save it for other projects .
They make liquid electrical tape. Just paint it on for quick isolation for wires.
Frank hopefully you still reading these. I followed your example so I could hot wire my MG90 180 degree servos. After I wired directly to the motors it now spins 360 degrees. This has happened on 3 monitors so far. Now when I wired it I did pull the monitor and the attached board out. Have you ever experienced anything like this? If so any suggestions on fixing it so I get my stops back?
Thank you for all the amazing videos you’ve really been a big help and inspiration.
I do still! I’m actually not sure about thah man. Maybe try asking in the electronics section of my discord? Discord.gg/franklybuilt
How do I make it turn the other way after it already turned withought switching the wires manually?
I've looked 3 times at my smartphone, just to realize everytime it was yours
Sorry! Haha
Thanks bro v
Exactly what brand of servo do you use? I’ve tried Tiankongrc from Amazon and the wires are so small it feels like only a surgeon could hot-wire them.
I to tried the tia and also tried the reversal and could't get to the 3 wires or even the board on inside. Motor portion was a snap but end up destroying it.
I was thinking what will happen if you forgot to off the switch, it will continuesly power even it is already on her angle limit, do you think it will damage the servo?
I had my coworkers play a massive trick on me and I would like to get back at them. My thought is to hide a liquid ass spray bottle in their offices with a servo that would automatically spray it, but I would like to have it automatically spray only once per day. Any thoughts how I could accomplish this on a build?
Will it work on sg 90 servo?
Hi, how can I use it on my HO turnouts. What I mean is for the motor to turn the arm just not too tight to move the tie bar flush on either side when I power it. Is there a device that can be adjusted to control the movement of the motor to my requirements please. I live in Sri Lanka and things are not that easy to find. Thank you anticipation of your help.
Do you have simple way to fwd and rev for that servo?
One question. Cant I just cut the orange wire and call it a day? I think I just screwed up one of my MG90 becuase its sooo small and hard to work withh. So I was wondering if cutting the orange wire would be enough
Hey Frank I wired my servo like you said but it just constantly spins, how do I stop it or only make it turn half or quarter? 🤔
Check my new helmet motorization tutorial. Video 2
@@FranklyBuilt will do thanks for replying
so after you're finished with both servos you put on the hinges and put them in to the helmet? if I'm incorrect can you make a video on how to install them
I have a video for that. It’s a live video called “let’s motorize a helmet”
ok thanks
How do you set it say a 270 degree servo to stop at 90?
Asl can you include a inline fuse to prevent hazards as well if you were routing it on a car?
How do I control it using a tactile/momentary button pleaseeeee
What happens at the end of the rotation ? The motor is still applying force frying to shear the gears ?
Some don’t have a stop built in. So you need to add limiter switches to kill the circuit
Yup.
are you using forward or reverse servos?
If you use this method, be sure not to leave the servo powered when all the way open or closed. This will burn the servo out.
If I just want a mini servo to go back and forth slowly non stop what would I need to do?
I don't understand how you make the servo
stops
A question to the Power Suply. A servomotor is a AC Power suply if im right. You used a DC suply. So how do you transfer the DC to the AC?
No a servo motor is not AC. Never out ac to a servo or motor lol 😂 you’ll blow it up. It’s a DC motor that needs its polarity flipped
But how do you control it in a helmet ? How do you get it to turn off when it's fully closed, or fully open ?
The jaw is magnetic. The controls are in the gloves
how do you limit the servo to say 90% without a data wire?
I have a 5v rechargeable battery pack and have exposed the wires of a usb cable, plugged it in and touched the wires to the servo wires to make sure they work, but I’m getting nothing from the servos, but the battery pack is lighting up as if something is connected, and it does charge other things, what’s wrong? I don’t think it’s the servo as I have 2 and both of them do nothing when connected, any ideas?
some battery packs need a load to turn on and give power out. I have one that works on the phone and headphones, but not the tablet blue tooth keyboard. The tiny servo may not have sufficient load to turn it on.
How much torque do these exact servos really have? They claim 13kg/cm so it seems like you could seriously get hurt if you stuck say your finger in the mask while it was closing. Can you stop it with your hand?
Thks for video,How can activate motor using a motion sensor using pr motion sensor?
I have been following your videos to a t... But no matter what I do my servos spin in different directions even if I use the spin trick with my hands please help me.
So I did this and the servo was working but now when it rotates one direction the gears jam and it won’t move back the other direction. Anybody know any solutions or should I just retry?
where can i found a diagram for the wiring ? trying to finish my helmet
luc killen right now I don’t have a specific one out. You can watch my MK85 update video 8-9 to see the system I use in my helmet
bro frankly, I have some question. Servo MG90 and MG90S is the same motor ? can the MG90S servo can be powered up by 4pcs x 1.5v batteries ?
The torque is different I believe and I don’t see why not but they will die very fast
@@FranklyBuilt bro frankly, which model servo do u can recommend to me for my motorcycle helmet visor? I took your idea to put into my helmet.
Whichever one has stronger specs
How do you make the face plate go back down if you got wire to like a 5 volt rechargeable battery pack
You need to use the switch
Hey I was wondering if you could send me a link to we’re you bought the switch at the end of the video
eBay. Search DPDT switch
@@FranklyBuilt Thanks man! Im currently making my own Iron Man Helmet
@@FranklyBuilt Btw how did you connect the battery to the switch?
With wires haha I have a usb battery pack
@@FranklyBuilt Thanks!
you literally saved my life i was gonna almost suicide
If i want to control it with a button of sorts how do i do it
How to use in a controlled rotation? A PWM?
Hello. Can't we just use a gear motor instead of this servo?
