DIY Linear Actuator

[@BowzerTowboats]

Great idea for lock doors keeps the speed more realistic too.

[@HidroteknikTr]

It's too simple to work, but it works! Congratulations.

[@RVJimD]

Yes, thank you. I plan this summer to make a video of the build of four new actuators for this system and use a larger motor.

Where to buy things

[@bigronshobbies8209]

That looks great Lock master Jim, this will make an add touch for some great videos : )

[@melikeserseri5974]

Süper böyle birşey arıyordum tam denk geldi teşekkür ederim 1:17

[@anoirnunesdesouza9074]

My friend, congratulations on your video

[@hafizrachmad517]

can you tell about the torque dc motor? why small dc motor can move that part?

[@RVJimD]

The small motor is geared down, so the motor turns very fast, but the output turns slow giving great torque and can easily move the door.

[@mrdillmale1633]

Dear Jim, Could you please tell me what type of metal holder are you using for linear actuator to hold. I am looking forward to hearing from you, Your faithfully, From Dill Doe

[@RVJimD]

The motor fits into aluminum channel.

[@MrSasha3050]

30 minutes has gone the door opened 😊

[@bhargavrock8532]

Hai bro this is how much RPM motor

[@RVJimD]

This a gearbox motor,I do not recall the exact ratio, but the motor is quite small and the gearbox might be 1000 to 1 ratio. Thanks for watching and thanks for the question.

[@Ed19601]

These small motors are more powerfull than people think

[@WAQARALAMLIVE]

what are you using to connect rod to motor

[@RVJimD]

That is a piece of aluminum I drilled each end to fit the two different shaft sizes and drilled and taped for set screws.

[@foodstick]

Jim, if you build one of these that will reliably run rc airplane retracts you will have made an improvement on the ones sold now ;)

[@RVJimD]

Possibly, be fun to try. Do you have an elec retract I can look at?

[@FlyingRob1]

You can buy such electric motors (=actuators) for example used in retracts since a long time, it´s not new.

[@foodstick]

Hi Rob, I was actually joking with him because several of my friends and I have bought electric retracts for bigger models, and have ended up going back to air.. They still have some issues with the bigger sized electric retracts. Hopefully someday they will work flawlessly (until you land hard) and tweak them ;)

check out this actuator on kickstarter www.kickstarter.com/projects/deezmaker/maker-muscle-worlds-first-customizable-actuator-fo?ref=nav_search

[@Basantvirk]

Aapne konsi motor use ki hai.. kitni vatt or kitne rpm ki ??

[@Oproprietario]

Esse controla velocidade? E pode usar com fim de curso para retornar?

[@shivaa3ps177]

When you write DIY, there should be an explanation of how you made the linear actuator

[@RVJimD]

I have other diy actuators videos that show more detail, thanks for watching!

[@RVJimD]

For those of you search impaired here is a link - kzbin.info/www/bejne/joS4qniKpaisb68

[@shivaa3ps177]

@@RVJimD You made a Great video. It's about an application of linear actuator but not DIY of the actuator itself.

[@UrgenthelpwithSubscriptionsHel]

Right. We have to dislike those youtubers who are thinking only for their money but doesnt help people in the comments section. I have unsubscribed and I have disliked this video.

[@latestsongs6058]

How to get front of motor,which u put stick

[@RVJimD]

Saad, I made the coupler from aluminum. It has two holes drilled and tapped for set screws to attach to the motor shaft and screw. Thanks for stopping by. Jim

[@YensR]

Awesome! Will those be radio-controlled as well? Would you have separate radios for the infrastructure and the tug?

[@RVJimD]

Yens, thanks. My friend if doing the software component. I think there will be a wifi connection and control using a browser. Should be very cool!

[@YensR]

Oooh, I hope you keep us up-to-date on that progress, too :)

[@Casavlog777]

فكرة جديدة و ممتازة أعجبتني كثيرا 😘😘👍👍👍👍👐👍👍👍

[@candelarioruiz5074]

Donde consigo estos aparatos aqui en mexico?

[@banggober8322]

please give me how to make it :(

[@baseljamal8907]

hello, whats the thread diameter?

[@RVJimD]

I think it is #10-24 threads per inch. It was typical threaded rod from the hardware store.

[@edfilmfactory2495]

how much weight this setup can flip

[@RVJimD]

Electra Dynamo, the motor is probably the weak link. This first attempt uses a micro gear motor with very small gears in the reduction which probably would not allow too much stress. This application is horizontal and I'm not sure what the force measurement is.

[@sidamarali3030]

The low torque motor is suffocating.

[@you-tubejunkie2926]

What is that door for ?

[@RVJimD]

You-Tube Junkie, the door is one of four doors on the lock chamber on the model boat pond. kzbin.info/www/bejne/fn6bf5ShjrSdotk thanks for watching!

[@munutango]

What's the model of the motor you use? Does it have an encoder?

[@RVJimD]

+Sirikit Joshi, The motor does NOT have an encoder. It is one of the common Polou micro gear motors. Not sure if this one was maybe 1000:1 ratio.

[@vishalgaurav4411]

What is that black rod ?

[@RVJimD]

Vishal Gaurav that is delrin, a type of petroleum based plastic.

[@vishalgaurav4411]

RVJimD what should I type to search that item ?

[@RVJimD]

Vishal Gaurav, here is a Amazon link Delrin Rod, Black, 1/4" Diameter www.amazon.com/dp/B00EJNSPVA/ref=cm_sw_r_cp_tai_8k7kBb9K7NCMX Im not exactly sure I used 1/4" and my plan is to recreate this for all four gates using 3/8"

[@vishalgaurav4411]

RVJimD can you please provide Ali Express link ? I live in India. Also are they having threads internally ?

[@RVJimD]

Vishal Gaurav, this rod is solid. I drilled and added internal threads using a tap to match the thread pitch of the steel threaded rod. I don't use all xpres, you should be able to find it using delrin or acetal rod.

[@motorconnaught3987]

good

[@TheVintagetamiya]

Brusehless

[@sangarp2001]

poor actuator

[@RVJimD]

Ya, this was my first prototype. What I learned from this was that using delrin with the taped hole in the first 1/2" and clearance for the remainder works very well. This is the same design style I used on my Tonka dump truck which works very well. I also added a down limit switch to the dump truck. Thanks for the comment! Jim

[@sangarp2001]

there is a saying "a long journey start with one first step", so keep going.

[@iykmoses]

sangarp2001 it's not poor. Since it's his first build. He need more encouragement

[@abuxxx3607]

poor comment

[@sangarp2001]

dont think you are giving an intelligent comment

[@SwarthySkinnedOne]

What a stupid lousy demonstration, not to mention poor usage of camera.

[@whocares4574]

Crybaby. Also, it's better than anything you could ever put out. That's why you haven't uploaded anything in the 13 years you've been here.

[@whocares4574]

Why are you so triggered? It's just a simple demonstration with some not great camera work. Did you expect him to somehow fit a whole lecture into 1 minute and 17 seconds? Also, it's an extremely simple device. Detail is not necessary if your iq is above room temperature. Regarding the camera work, it's not the best, but it isn't exactly indecipherable. Again, it's such a simple device that only a few seconds are needed to understand it. IMHO, don't click on very short videos if you want thorough explanations, lower your stupid lousy standards, and work on your comprehension skills.
