Thanks for the comment! I like your ideas :)Actually, you don't really need the dotted pattern - it's, in a sense, the optimal pattern to use, but any pattern could potentially work! so your idea about the trees and such could work :)To reconstruct the waves that formed with deformation of the pattern, you need some physical theory of what's going on. Here, the authors of the paper used Snell's law, but in other cases you'll have to use other tools (perhaps Snell's law would work as well). In the case of earthquakes and such, part of the wave is longitudinal. Such waves can measured directly using PIV without the need of integration! I'm so happy posting this instructable inspire you with so many great ideas! :)

thanks for the question! The method I showed is made of two separate parts. First, we measure the deformations of the dotted pattern (the displacement field), and then we use the measured displacement field to reconstruct the waves causing the image deformation. In stuff like you showed, you actually don't need the second part - all you need is the displacement field itself. For that, PIV is a perfect method. Instead of tracking individual particles, like Stefan (and any other particle-tracking methods) use, you look at the entire image and look for a displacement field that minimizes the difference between the two images. The paper you attached uses a DIC method, which is similar to PIV. The answer to your question is yes - and it should be really (really) simple to implement! Try lookin…

Try looking PIVlab to see what people use it for, and you should get the idea. PIVlab is based on MATLAB, but you can find similar software for free (let me know if you need help with that!). p.s. - you can use PIV with nearly any optical setup since you can use the method to measure the lens distortion too! :)

The method I showed is based on an image being deformed. If you're looking at a phenomenon that deforms some kind of an image (being optic or anything else), you can try to reconstruct the phenomenon that caused the deformation of the image. In the case I showed, it is assumed that the deformations are small, and in that case, you can use Snell's law to map the deformations of an image to the deformations of the surface itself. The good news are that if you look at small enough deformations, often things will appear as linear and methods the like ones I used here, apply.Thanks a lot for the comment! your ideas are super interesting! :)

Thanks for the comment and for the link! I'll make sure to include it in the text ASAP (and give you credit for it). I was unhappy about referencing to a paper which most people cannot access. Thanks!If you need any help with your ideas, let me know! :)

The potato thing does work:) it provides instant pain relief and no long-term effects. I haven't tried white toothpaste, but thanks for the idea! And thanks for the comment:)

Actually, I think this could potentially work, but you should have to make some modifications. This is a great idea for a future instructable, which I might actually make if you don't mind! :) The idea behind this method is that you need a reference image to be able to track these imperfections you mentioned. In the method I showed, you would have to place a pattern beneath the bed and it must also be transparent, so you could see the imperfections. However, there are ways to overcome this! Instead of placing an actual printed pattern, you can project one! That's a valid method which is quite often used in physics experiments. That way you don't have to make any changes to your printer bed. So - yes! it is possible! but you'll have to do some work :) maybe I will do it sometime!Thanks for…

That's probably the nicest comment anyone has ever written!! Thank you so much :) I appreciate it!!!

Thanks!!

Hi, and thanks for the question! The problem with bubbles is that they severely deform the surface between the bubble and liquid (water), while the method I showed here depends on a 'small angles' approximation. This could result and what we call 'ray crossing' - light bouncing off entirely different areas of your image could be deflected towards the same point in your camera. So I believe this method wouldn't be too helpful for your case. However, maybe there are other methods. For one, I can think of ways for estimating the 3D volume of a bubble given it's radius measured by 2D images, but my guess is that you guys are already doing this.Do you capture just 2-D images (like the one you attached) or do you have other cross-sections as well? I'll try to think of a way similar to what I sh…

I'll try to think of a way similar to what I showed here that might work for larger deformations like yours. If you like, send me a message and give me more details, and I'll see if I have any ideas.Thanks again for the question :)

Looks great:)Also, I appreciate the fact that people can recognize that you're the author just by looking at the cover photo! :) well done :)

there's absolutely no need! :) thanks again!

Awesome:) thanks for sharing!I especially appreciate the tip about throwing it out! I would have definitely let a kid keep it if you didn't mention that!!

nice job :) I appreciate the details as well. (since the uncertainty in U and lambda are independent you probably want to calculate the root of the squared uncertainties [Pythagoras] , not their sum) thanks for sharing!

These look delicious!!! Thanks for the tips:)

Thank you so much! :)If you ever go for it and need some extra pointers, let me know!

well done :)I recommend PIVlab if you're looking for quantitative analysis of the models you're testing! it could help you measure the flow field. Thanks for sharing!

Great job :) I love your ideas.Thanks for sharing!

well done!! That's a great piece of work :) thanks for sharing!

I love it :) Thanks!!

The use of 3D printed stuff objects it ingenious! thanks for sharing :)

You're very welcome! So glad I could help :) welcome to instructables! hope you're here to stay :)

It looks amazing! so does the view!!

That is awesome:) thanks for sharing

That turned out great! thanks for sharing! :)

This is great! I love how it turned outThanks for sharing :)

I'm really glad your instructable was reposted! It's awesome and I would have missed it! Thanks for sharing! (even if it was a while ago!)

I appreciate the simplicity, well done:) Thanks for sharing!

I love the cork holder! thanks for sharing :)

If anyone is reading thid, this instructable ia full of wrong explanations!

It turned out great! It does not at all look like a first project!! Well done and thanks for sharing! :)

That looks great! :) And I love the pictures too! you did a great job documenting and explaining everything, thanks a lot for sharing! :)

great job! I've never heard of this technique before! thanks for sharing :)

This is a great design! very inspiring :) thanks for sharing!

Thanks for sharing!The cleaners I know are based on high frequency vibrations (ultrasonic baths), is that what you were aiming for, or did you just want something to shake the box on it?p.s., I think your videos might be distorted because you're using video stabilization while trying to focus on a moving object:)

congrats! hope you win big :)

That's evil!!

awesome :) thanks for sharing!

Thanks so much for the tips, I'll definitely use something like that next time! I really appreciate the time you spent on commenting & helping me with the concrete stuff! Thanks again!

of course:) glad I could help

they're a great band!! :) Thanks a lot for the comment :)By reinforcing you mean put some wire mesh or something? I'm really new to concrete, that's probably why mine crumbled! Any advice would be appreciated :)

Thanks a lot jessy! :)

you did a great job on this :) I really hope you win! Thanks a long for sharing!

I love it :) thanks for sharing!

Looks great, thanks for sharing! I'd love to see some more pictures of that lamp too!!

I love the simple solution you thought of, but won't changing the computer's sleep settings be even simpler? is that not possible at your work place?

great job :) thanks for sharing!If you ever make a stop-motion video I would love to see it too! :)

amazing :) your designs are inspiring. Please keep on sharing!! Thank you so much :)

don't be sorry that your photos are upside-down! I saw your intro photo and thought you made a real-size rocket! hahaI found that you cannot flip images in the instructables editor - you have to do it before uploading (I just do it in windows). Hope that helps for next time!Nice project, thanks for sharing :) good luck in the contest

awesome:)my cat used to love laying on top of it since it kept her warm.. maybe add a balcony?:)

Impressive work:) well done

Never heard of this technique before! Thanks for sharing:)

A basket full of braided brrad buns sounds fantastic!! Thanks for the comment! :)

It looks delicious!!! Well done I'm so glad you and your family liked it!! My family got hooked too:) good thing it's fun and easy enough to make!Thanks for taking the time to comment and share your results! It makes a huge difference!!:)

That's so nice of you :) well done! good luck in the contest

wow that looks amazing!! :) So glad you enjoyed it! Such a long braid, I love it! this inspires me to make something similar on Friday!! :) Thanks for spending the time to post! I really appreciate it :)

Awesome project!! Well done! I voted for you, hope it makes a difference. You're really talented!!!

Hi, thanks for the question.In my experience, whole wheat flour lead to denser bread, so when I tried optimizing my recipe I didn't consider using whole wheat. Whole wheat flour is so different from white flour when it comes to bread, and for a Challa recipe that's going to be even more pronounced. So the answer is, sadly, that I don't know!Since people usually want a really tender and delicious bread when the eat Challa, not many people use whole-wheat. It's kind of like replacing a beef burger with a veggie burger - people do it, and it can be pretty tasty, but it'll never match the real thing. Sorry I couldn't help more!

Never heard of someone having a Smurf wedding before! that's really cool:) and the cook looks amazing!! The details are overwhelming! You're a living proof that you don't need to know the science of baking to be a great baker. I hope you'll start posting your recipes soon! Instructables is a great place to share & I highly recommend it :) Letting other people enjoy the stuff you make is awesome (and you can actually win some really great prizes). See you soon :)

wow those look great!! If you made those without a recipe you must be super gifted! :) I think that you're closer to a recipe than you might think! Once you have the feel for it, just measure the stuff you put in before you do, and see what comes out. By now you probably know what each of the ingredients in your recipe does and how modifying each it would affect the final product. So if your bread comes out, say, too hard, you know how to fix that.If you want any further advice feel free to contact me here / message me :) I'll make sure to follow you just in case you decide to post recipes for those!

Haha! :) Well I don't have lots of free time, but you know how it is, I'm awake for 17 hours a day and I try to make the most of it. I just have to stay at 100% efficiency :) Oh and posting this instructable took me about 3 weeks to film and write, bits and pieces of free time stack up!! Thanks a lot for the comment :) I really do appreciate it!

haha sure :)

Thanks! I thought I fixed that, but looks like I only changed it in step 2.Done! :)

I'm sure you will! :) Hope you and your family enjoy it :)Thanks for taking the time to comment!

Thanks! So glad you enjoyed the instructable.And thanks a lot for taking the time to comment! :) It makes a huge difference!

Looks great! Thanks for sharing & good luck in the contest:)Did I miss the part wherr you used strawberries?? Maybe you replaced it with apple sauce?

Awesome:) Can you give us an update in a few weeks/months to see how well it was preserved?? I love the idea:) thanks for sharing!

That sounds great! :) Thanks for taking the time to comment! So glad you enjoyed the soup:)

Thanks for the answer! I love how scalable your project is. Also, I think this could be a really useful (and cheap!!) way for capturing the location of instruments in many Arduino projects. For example, linear actuators that indicate their current position (like a servo does) are super expensive, but ordinary actuators are way cheaper. Your idea can be used for cases like that. Thanks for the insparation :) great project.
