Glad you like like it! :) Any ideas how to make other uses of it? I didn't even look at it that way! Maybe I'll add an Arduino version of all this!

awesome job! :)

Thanks!

Thanks for sharing, and welcome to instructables!Just wondering - would making different types of beer require different equipment, or do you just use a different recipe / process? thanks!

https://www.amazon.com/LAFVIN-Include-Ultrasonic-B...what's the difference?

haha the black/white video is great!! thanks a lot for adding the videos it makes a huge difference!!

awesome :) I've never seen a tiny rocket before!

cool project! well done :) looks like a lot of workAlso, the take-off video is great. You can click 'embed video' in the instructable editor - it would make it easier for people to see.

you made that out of nothing.. that's amazing! great job! got my vote :)

looks great!

can you add some videos of paper planes flying??? and maybe some detailed instructions?:) thanks!

sorry to hear that, but hopefully that'll give you more time to bring larger traffic around here, maybe get closer to what we had a few years ago :)one question though - where will you be posting announcements (such as this one, upcoming contests and more)

Nice job!:)

Thanks a lot for the feedback! Glad to hear you like the idea :)as you mentioned, razor blades could work too, but actually I like the fact that these are less shiny -> safer! If you're going at it, maybe also try to hold a single hair against a laser-pen, that would be the simplest way. Another cool idea is to shine a small spring with your laser (springs just like the ones you find in regular pens). This leads to a diffraction pattern similar to that of the structure of DNA! This is basically how people found its shape in the first place!

Finally a simple solution!!! great job! I love how you don't need any sensors, arduino, programming or anything too sophisticated.. just a good idea. great job!

Thanks sharing :) looks great!Does the glass jar ever get too warm? Do you think it might fail?

Looks great! I love how you used the area under the bed! well done! Thanks for the ideas :) hoping to see more instructables soon!

Can you add a few pictures of the inside as well? looks like a nice camping van :) also, maybe a picture of the entire back door covered? And one more thing - can't the door close on you?? welcome to instructables:)

I like how you made a letter seal with it :)

nice upgrade :)

great job! Step 13: Use at Your Own Risk!

Are you sure that's not a waste of good steaks??:)

bravo! :)

well done!!

the dragons are cool too :)I think letting people know the secrets of how you make stuff is a good idea!Don't be afraid that your ideas will be 'stolen', they'll still be yours, but others could enjoy them too! that's what instructables is about!

looks great:)

Awesome! I love the idea! good job! :)

Nice job :) I like how all your tools are kind of home-made.well done!

looks great! I'm glad she liked it after all the effort you put into it :) good job

Nice project :) how did you hang it?

I made something very similar my modifying an old hair-cutting machine :) It ended up looking very similar to your design, and it had the same problem - it didn't really work! It got stuck as soon as I tried to use for serious jobs.My point is... you're right - it's about the process!!ANDyou can still use it!! For example, you can use it in the kitchen! turn in into an electric whip or something :) (when I made my instructable about making an electric whip my first goal was to transform my lame home-made dremel for it)good job anyway :)

to be honest I thought it was going to be made out of Lego! But I like the design and the end result, good job :) wish I had a 3-D printer...

So many MCT students from Howest lately:)Good job on the project!

I like the idea! :) thanks for sharing

nice job:) thanks for sharing

Nice project! Is really enough light for your plants? do they live longer now??

Thanks!!:)

Thanks a lot! I hope you make your own!:)

I wonder what happens if you walk around with this mask....... :)

looks perfect!!

I love it :D good job

I like the idea but do you have any use for it???

nice job! :) thanks for the detailed instructions!

Is that really just tap water?? nothing else?? looks like magic :O

Welcome to instructables! :) Thanks for sharing your idea! it looks like you put tons of effort into this project (and into posting it!). Would it be possible to add a few more images of the final result? maybe a short movie? I'm not sure that I completely understand the demo you uploaded and what the different lights indicate.Thanks and see you next time! :)

I always wondered how they coat these.. thanks! it came out perfect:) good luck in the contest!

nice project! good luck at the contest:)

great job! Turned out perfect :) got my vote!

You could place a ruler next to the object and take an image. By using simple free software (ImageJ for example), you could calibrate the images so that instead of reading the distance between two points in pixels, you can actually measure real distances. Of course your method is more accurate :) But the upside of what I said that you only take a couple of images and someone else can measure what ever he likes.

looks great!

got my vote :) thanks for the tips!

nice job!Can you approximate how much energy it requires to work per liter/gallon of water? :)Also, you might wanna add some information to the title so people will click it more often! :)

I'm going to try and make one of these! thanks for sharing!!

Thanks!About what you said about different parts of the speaker making different sounds (just because it sounds like you might be interested):Each moving part in your speaker (or any other object) has its natural frequencies. When you plan music, or even a single tune, chances are that its not one of the natural frequencies of your speaker (or any of its moving parts). Since its not a natural frequency of the any of the moving parts, it will invoke many harmonics, and not a single tune, and since each moving part would have different natural frequencies, each of them would have different harmonics which makes them sound different! that's why playing the same note on a piano or a guitar sounds different, it's all in the harmonics!So the vibration of each of the parts would be mostly of t...

Exactly! I figured many people on instructables.com would have an electric drill/screwdriver but no baking/cooking tools (like you and me). If you do end up making it, I'd love to see your 3D design / result!

Waiting for the pvc stand:) nice and simple projectGood luck!

Thanks for sharing!! The template idea makes so much sense!

nice job :) I like the idea, could be useful!

Nice project!from my experience, featured projects are often selected by their pictures.Make sure you look at some 'How to take a good picture' instructables/classes! Good luck :)

Nice project:) looks cool!I was wondering about a few things:1) why do you need the cling-film? Isn't it enough to just attach the mirror to the speaker? It's already shaking by itself, isn't it?2) In step 1 it looks like you did connect the mirrors to the speaker itself, but then at the 2nd step it looks like you covered it with the cling-film. At the mirror attached to the cling-film? (if not, I'm trying even harder to see why you need that part for the project)Thanks!

Thanks for the detailed explanation 👍

Nice job! The title was a bit unclear but the videos and pictures speak for themselves

Very nice job :)

I have a stack that I didn't play with for maybe 15 years.. still, they used to be so expensive that making a box out of them seems crazy (!!) to me :) Nice job :)

Nice project!! I'll definitely try to make one of these!

congratz! :D You deserved it! well done!
