How to Make a Zoetrope

[@MariaLuizaLimaBezerraDeFranca]

I have first graders and they’re fascinated by this, thank you so much for the files. Me and them we are so thankful for your time building this! You are one of a kind ❤

[@MChipsTV]

This is great! I'm a high school teacher teaching animation to a group of Year 7s and they really enjoyed this activity. Thank you for producing this content and resources and sharing it with us for free. You are amazing.

[@RimstarOrg]

Thanks for letting me know! There couldn't be a better use for it. Kudos to you!

[@sabyasachinayak24]

This is how they used to make gifs in olden days.

[@zagaberoo]

You have a unique clarity of instruction. "Fold along the dotted line, or just fold evenly". It's a simple step, but I'd imagine with kids especially giving multiple ways of looking at the same operation is helpful.

[@anilshirsat4406]

Just like you add creativity in the kids , to prosper their world of curiosity and enthusiasm .👍

[@owenguo6235]

I've always wanted to make a zoetrope! Thank you so much! it's a dream come true:)

[@mrankles7465]

Preciate you for this!! 💐 (I subbed and put all notifications on , as my thanks for this video)

[@stevethecat9194]

This is awesome. I'll be visiting your site. I'm a physics teacher and sometimes it's not only useful to get away from the graphs and online simulations, but there are some concepts that just lend themselves well to animations. Great video. Very clear and concise. Thanks.

[@RimstarOrg]

Thanks. I'm glad you like it. Having the students see the difference between when they look at the animation straight on and when they look at it through the slits should get them scratching their heads and as good scientists should, hopefully they'll theorize why, maybe even come up with experiments? Have fun!

[@cam9cam9cam9]

Ever since I was a kid, i always wondered how to make these

[@ghosteondogedoge4787]

Dude : portal gun from half-life Me : say sike right now

[@jaquegro4759]

Thank you for giving such good instructions! You answered all my questions before they actually arose in my mind :D

[@AirborneSurfer]

Oh, man! I loved playing with zoetropes when I was a kid! Great memories!

[@schoolaccountvlog]

This helped me so much to prepare my school project. Thank you!

[@RimstarOrg]

I'm glad to hear it! Thanks for letting me know.

[@metatrontf]

Thank you, sir! This is so helpful!

[@RimstarOrg]

Thanks! I'm glad to hear it!

[@scottadams5858]

Very cool project for kids, I'm totally going to try this, thank you for sharing this with us, love you videos

[@RimstarOrg]

My pleasure. Thanks for watching. The animations really are a lot of fun to make.

[@scottadams5858]

@@RimstarOrg it totally look like a lot of fun for all involved

[@hollysanefski9511]

This will be perfect for my science class on Thomas Edison! Thanks!

[@RimstarOrg]

Thanks! I hope your students enjoy and learn a lot from it!

[@YaxaSRI]

Thank you so much for the pdf's

[@greattit]

This looks like a lot of fun for young kids :D

[@dfortaeGameReviews]

Thanks for all that you do!

[@RimstarOrg]

It's my pleasure! Thanks for your support!

[@linahtareksoliman7795]

You are a life saver ❤️✨

[@528kaison]

Thanks I have done my project

[@chachelawson5149]

great video! but the portal gun is from portal not haft life.

[@RimstarOrg]

Thanks! Ah, when I checked before I found it on the Half-Life wiki half-life.wikia.com/wiki/Aperture_Science_Handheld_Portal_Device but I see now it says it's actually in Portal. And I now see that Portal is just set in the same universe as Half-Life en.wikipedia.org/wiki/Portal_(series). Oh well.

[@DoNotPushHere]

well they are supposed to be stories of the same "universe" at some point along the HL saga someone mentions that the partnership with Aperture science got rotten because they didn't care about the subjects of their experiments... :D the cake is a lie :P

[@deborahanne675]

Thank you so much. ☺️🙏x

[@SalihArtAndTech]

Very Informative. thanks for this video.

[@TheNei]

Very funny and cool!!

[@veerarajph]

Thank you

[@viviemorton14]

were doing this for my animation class :D

[@RimstarOrg]

Awesome! They're certainly lots of fun to draw.

[@bobpourri9647]

Great! Thanks.

[@PepperPizzaPasta]

hey man i love your tutorial good job!!! :)

[@aibohpphobia6246]

This is so cool!

[@mrbroomallsciencevol1006]

Very cool. I'd like to make these with my students animating the phases of the moon. Do you know if there is an easy way to adjust this for 8 images instead of ten? Thank you.

[@RimstarOrg]

Thanks. Download zoetrope-blank.pdf from my webpage here rimstar.org/science_electronics_projects/how-to-make-a-zoetrope.htm , print it out, and draw new lines on it such that there are eight spaces to draw in instead of ten.

[@SillyBobScience]

Good zoetrope. We had fun making one too.

[@Miss_Prowlheart]

yesss this is so cool i love animating and i like to make flipbooks ... but this is even better than a flipbook!

[@DoNotPushHere]

Hi there! I had some experiences with zoetropes and I found that the images tend to stretch down the horizontal axis by a factor of 50% have you experienced the same? analyzing the zoetrope itself I rhink I found the reason in the fact that the slit runs at the same speed but in the opposite direction from the picture itself, thus the image looks 50% shorter in the plane of spin. That was my own experience but I found no literature about it. did you encounter the same effect? thanks!

[@RimstarOrg]

Now that you mention it, I see a horizontal shrinking effect, maybe by 50% and regardless of the direction I turn it. Another thing to consider is that the slits are so narrow that I don't see the entire object at any time. That means the eye/brain has to do some processing to put it back together and so maybe it guesses wrong.

[@DoNotPushHere]

RimstarOrg hmm my experience is that the brain guesses right. I didn't do a great job last time describing the alledged explanation. I'll try again: easy explanation. Imagine one single frame. You have to see the frame through a slit, so you run the slit along the frame, and you rely on your persistance of vision to see the whole frame at once. If the frame is static, the slit must run along the side of the frame, say a distance of 1cm. The slit moves at 1cm/s but for now it does not matter. But if the frame moves 1cm/s to the opposite direction, the slit gets to the end of the frame in half that time. So the slit has shown you the same frame in half the time, and... (dramatic drums) half the distance! thus the lenght of the frame appears to be 1/2cm! does it make any sense to you?

[@RimstarOrg]

Yup, that does make sense. I guess a solution would be to widen the slits to get the whole object into a single viewing or move the eye closer if the slit is wide enough to make the help (I can't get close enough to mine to see it).

[@DoNotPushHere]

RimstarOrg I dont wanna sound like a smartass, but I am afraid that the width of the slit does not affect the phenomenon. Actually, if you are familiar with photography, by widening the slit you will get a brighter picture but much more blurred. Same thing if you get your eye closer to the slit. You are virtually making the slit dissapear, thus you dont get the shuttering. Imagine a slit so wide that would meet the slits on the sides... problem solved? nope And from a mathematical approach, you can see, the width of the slit is not part of the variables that I have used to describe the phenomenon. Back then I just opened Paint and widened the frames by 200% on the Y axis. That should stop me from lingering you any longer and fix anyone's problem :P Anyway, glad to meet a zoetrope again. I use to follow your projects but electronics is definitely not my field. This one I really enjoyed how simple yet effective it is.

[@m.gracekeech4960]

Oh my gosh, this is so cool!

[@jhowardsupporter]

It is. I've seen them in a few movies and stuff, it was even in the intro for one of the James Bond video games. I just never knew what they are called.

[@SharowbladyeGaymerPorate]

pne of my uni asssignments is to make a Zoetrope and this is a huge help

[@Alphaship]

Can I also use a dc motor, so that I can just focus on the animation

[@RimstarOrg]

I'm sure a way can be found to power it using a DC motor. Even just taping it to the top of something that rotates might be good enough.

[@biarritzzz]

so great!!

[@boo5681a]

Cooooooooooooooooooooool

[@amarimboanga2255]

MALI ATA SINABE NI MA'AM AHH HAHAA😂😂

[@luzelvlogs209]

omg tysm

[@pranavkraj8128]

Can i print it on an a4 paper

[@RimstarOrg]

You'll have to do some test prints and rescaling to get it to the right size to make it work.

[@Ayri389]

Nice vid

[@Ducksauce33]

Nice!😵

[@RimstarOrg]

Thanks! I'm glad you like it!

[@Ducksauce33]

You're welcome! Whats the fraction you use to get difference between the size of the black shutter squares at the top from center to center of the cut out notches and the sections you have marked to draw in on the bottom. It looks like the drawing area is like 1¼ the size of the black shutter sections. Just wondering so I can make different sizes.

[@RimstarOrg]

The slits are around 7.5mm and the black sections are around 37mm. Each drawing frame is around 42mm. I selected them all pretty arbitrarily. Basically I figured that 10 frames would fit animations which would be visible well while still being spaced apart well. And the slits were selected just by watching other people's videos and seeing what other did and how well they worked.

[@BillySugger1965]

Great resource, thank you! But could you please also print to PDF templates for A4 sized paper, for the 97.5% of us who aren’t North American? Thank you 😊

[@RimstarOrg]

I'd like to but I don't think I have any way of testing it. I'll look around.

[@catsoften]

Billy Sugger so that's what A4 paper is.

[@BillySugger1965]

RimstarOrg I’m happy to test it for you.

[@BillySugger1965]

catsoften Yes, it’s the letter sized paper used in the rest of the world. The great thing about the A-series of paper sizes (besides being available the whole world over, apart from North America), is all sizes have the same aspect ratio of root-2:1. So you can create a document for one size and print it on any A-size just by rescaling it. And if you have A4 paper, you can make A5 by cutting/folding it in half. So if you have a booklet made for A4 printing, you can make low cost versions by printing both sides in ‘booklet format’ on A4, centre stapling then folding in half to make an A5 booklet half the size.

[@RimstarOrg]

Billy Sugger Cool info re the A-series! I love it when things work out like that. I'll take you up on that offer to test it because I'm not having any luck with the printing stores around here. I guess there's no demand for A4 in our area. Send an email to [e-mail] and I'll reply with some PDFs to print. It won't be until later today. Thanks!

Why can't u put it on a motor

You can put it on a motor.
