How to build a telescope from a hard drive

[@saadtiwana]

The way you made a concave mirror out of the hard drive plate is pure genius!

[@abumoslemtamer7331]

Anyone who has a simple idea about optics knows that the owner of the video is a liar! In order to make a mirror suitable for astronomical use, it must be highly accurate in terms of concavity, whether spherical or parabolic A concave curve can never be created using hand pressure on a cup!! A mockery!

[@jirik_cz]

What about colimation? And the primary mirror isn't concave/parabolic, you can see that because there's no deformation of the reflection when you were showing the telescope. And if it would be concave/parabolic, it's hard to trust that you made it this precise, and even the eyepiece outline is too perfect. I don't trust you sorry :D

[@unperroarmado5456]

Like how much force did you use for the mirror and how much focal length did it have?

[@SergeyIvanov25]

This is 100% fake. I took a screenshot before and after pressing the disk and they are absolutely identical reflections of the picture in it.

[@luisfontesoficial]

Será que você não estava usando um disco com espessura diferente e talvez não tenha usado força o suficiente para curvar adequadamente o disco?

[@Propustite_wivaita]

[@jatindersingh4299]

You need concave mirror to create magnification

[@calind9393]

I had this idea too, but to use vacuum to make the mirror concave. It's great to know that it works and I'm definitely going to make one now! Nice work!

[@wahabsafi4420]

did your telescope work

[@AndyP3r3z]

How do you do this? I saw the cup thing... But it's not clear to me how that would make the mirror concave :/ I only have one HDD plate, so I would like to use it wisely...

[@h.n.4060]

@@wahabsafi4420 I tried this myself. Built a 20in mirror using a drum that I could pull air out of. My results were just okay. Because of distortions on the edges I had to mask off most of the mirror, giving me an effective aperture of 10in. I was able to get an image, but it was of very poor quality. It might be very good for spectroscopy, but not so much for imaging or using an eyepiece. The biggest problem though was getting the vacuum to hold. Even small changes in air pressure, air temperature, or tiny leaks resulted in enough of a change in focal length that it was impossible to maintain focus for more than a dozen seconds or so at a time.

[@Shelep524]

May I ask what diameter the main mirror of such a telescope turned out to be?

[@Astrovibrain_laboratory]

Hi, what could be the focal length you achieved by pressing the disc? Does it got raunchy test pass? Could you please reply

[@bardiyaabbasi5748]

First of all the video is fake second he ain't responding

[@IdeationGeek]

"The non-magnetic substrate material used for the disks in hard drives is often aluminum or glass. Aluminum was commonly used in older hard drives." (ChatGPT) "Depressing a circular ring on top of an aluminum disk would indeed cause it to bend, but the resulting shape would not be a perfect parabolic function." (ChatGPT) "The resulting deformation in the aluminum disk from a centrally applied load would likely resemble a combination of a parabolic shape and other higher-order functions." (ChatGPT) Could you say what was exact diameter and border profile of the cup you've used? Do you still have the specific model of the hard drive? I'd like to see how repeatable it is :)

[@AdityaRaj_6350]

I mean his idea is genius tho As hard disks can be great concave mirrors If only there was a way to make it parabolic at home

[@PauloDand]

The amount of people believing this and not realizing the moon on the phone was a pre recorded video is absolutely scary...

[@SeanDespres]

I had this ideal too but never got it to work I'm going to retry it soon but I think there's a way to do this with a normal mirror but would be much bigger and much more powerful but would be very hard to do but if got it to work then that would be great

[@jhonenadahumanosalenda]

I'm going to try to curve some disk but in a smart way, screw stretcher like corkscrew

[@SeanDespres]

You'd just need some type of frame around the mirror and something like a piece of wood at the bottom to hold the 2nd hook that's holding the 1st hook that's holding down the center of the mirror I hope you can try this one day too

[@SeanDespres]

My ideal was to just use one of those hook screws that you use on your ceiling to hang stuff but to put it under a regular mirror right in the middle and use another hook to pull the first hook down but would have to be perfectly centered and the 2nd hook can't pull the mirror down too much or mirror would be far too curved and wouldn't focus properly I'm not sure if you get my idea but I will make a video on it one day when I have what I need then I'll try to see if it works or not

[@pongzachanel4185]

May I ask you? Can pressing like that really make it curve?

[@Kot_Baton]

The disk is very dense, I could not bend it with my hand. I showed in the video what to do. in fact I used my body weight to bend it.

[@ronysetiawan7184]

Good effort, to get a sagitta it requires a little bending, I've wanted to make it a little curve for a long time, even though it's very far from a parabolic shape, even approaching a shperical shape is very difficult, sometimes I wonder if it could be thinned until it's shaped like a sticker and then stuck on a parabolic mold, for example using 3D printed plastic...

[@timsonjava]

Deep research and asking an Ai I found out this theoricaly possible but it's not recommended platter is not made for optical uses additionally it can't reflect ligth much so u will get a bad image.

[@rudrasingh4856]

What is the focal length of the drive disk???

[@Kot_Baton]

I first deformed it, and then made a pipe for the focal length.

[@julesxfnaf4597]

you could create a cassegrain telescope without the first pane just with a classic cassegrain search cross

[@barmsoon]

Nice joke😊 Il n'existe pas de moyen (malheureusement) de déformer convenablement une surface aussi précise que celle d'un disque dur sans développer de grosses contraintes. À froid avec une tasse (une tasse d'un labo secret de la nasa sûrement😅) c'est incroyable. Dans aucun cas , mis à part dans les publications des chercheurs de Putin, un montage comme celui ci ne pourrait rivaliser avec un oeil nu.

[@urpc.politics1]

You should put a rock instead of a coffee mug to press down on the the mirror. Asking why? Because it rocks.

[@DIY_TelescopeMirror]

Don't try this again! It is impossible to make a parabolic mirror from an HDD! I tried it and there was strong distortion in the center, everything was crooked! The author of the video shows that the disk is not deformed at all, you can also see how the phone moves on the eyepiece contrary to what is happening on the phone screen! I took pictures with my phone through the eyepiece on a real telescope and I know what it looks like!

[@igorcruzz]

I have the same ideia while ago, but I broke my disk, and any try to press him to deform in a concave shape, even though smoothly and gently to avoid to break, it ended with zero magnification.

[@actiontech5948]

tell me in a good way how this can be made in parabolic shape

[@Kot_Baton]

you won’t be able to make a parabola, you need to make minimal deformations. I messed up a few discs, until at least something worked out.

He achieved that by pressing the disc with the cup.

[@Sharpless2]

@@SuperJoseee This is in no way parabolic whatsoever. Its not even spherical. And this isnt even real btw. Look at the field stop (the black outline in the eyepiece), its is WAY too perfect for what he made. If you know how telescopes work and have used them for a few years, literally everything in this video dictates that this cant work whatsoever. Not a single chance in hell that this would work. Theres a reason why an 8 inch parabolic reflector mirror costs 250€ if youre lucky and a 10 inch (just 5cm more) costs upwards of 700€.

fake..this is not a telescope..it is just a reflector..because the hard drive mirror is very fragile..and no way you can make it concave..because it is not metal..its glass..try forcing it into a concave shape ..it will break easily..one more thing it very best to make a secondary mirror as it is a best mirror u can find ..

The disk is made of aluminium. It has a reflective coating. It is easy to deform and it will keep its shape, you need to do this carefully, as it is easy to spoil.

То есть, для экспериментов хватит с головой ! Но сколько я ни искривлял таким образом блинчик, в центре искривляется по-любому сильнее. И что интересно - автор видео не показал по-нормальному выгнутое им зеркало. У меня вообще складывается ощущение, что он другое зеркало вставил. Фабрично изготовленное. А нам конечно же не показал. Зачем так врать? И последнее : вторичное зеркало почему круглое? должно быть эллиптическое ! Изображение с круглым должно быть ограничено справа и слева, а оно нормальное. Фигня короче.

You are right. True telescope mirrors are unfortunately pretty expensive (i do amateur astrophotography and have a 150/1400 Newtonian telescope). The reason it's expensive is how precise the mirror has to be in order to work.
