Uma Roladora de Metal! E Bentonite, um Isqueiro todo-o-terreno, desenho Paramétrico, e a minha Delta 3D!

Mais uma bela dica da Construindoo, canal da autoria de Igor Kipgen, este impressionante Vídeo, de uma série de Vídeos, Make it Extreme,  sobre como fazer uma catrefada de Máquinas-Ferramenta, em vossas casas!
Maravilha! 
Esta, é uma Roladora de Metal, Chapa, e Tubo, que fazem com uma Rebarbadeira, (Esmerilhadeira, no Brasil), Soldadadoras MIG e TIG, e freeamental variado.
Não há limites, com este nível de Engenhoquice...







Homemade Roller Bender
Make it Extreme

This time we decided to MAKE this CONSTRUCTION to give to our viewers the opportunity to also, try to make their own METAL BENDER at their own home through electric welding, using an angle grinder and a drill.














Para a Fundição, em Moldes sobre Areia, é preciso Areia de Fundição, claro, e eis como se faz:







Bentonite Green Sand Recipe. Sticky, Oily and Just Great!
DuralM

This is my new green sand mixture. This one consists of 87% of sand and 13% of bentonite clay. And some water of course :) I think in some way it's little better than my last green sand formula which consist brown clay. Bentonite clay is very sticky and oily. It's very different from brown clay. And this time green sand is really green! :)












Este Isqueiro é um Isqueiro para levar a todo o lado, e podem fazêw-lo em casa, para vossa edificação e delícia, e para terem uma ferramenta essencial, nestes dias em que nada é certo...







Uber Lighter 2.0
lonesoulsurfer

Burn everything in your path with the updated, ups-scaled and most awesome of lighters
This build is easier to build, you can change the wick simply and without any fuss and ascetically, it’s a much better looking and hardier lighter (in my humble opinion). Also it's around 40% larger as well! The size of the lighter will depend on how long you make the body section. I decided to make this version even bugger than the first.
Instead of fabricating a sparker section as I did in this 'ible, I went down the easy road and brought one on eBay. I’ve also added a screw cap to the end so filling-up the lighter and changing the rope (which you probably won’t do for years) is a tonne more easier to do. Also, the lighter is all made from off the shelf parts that you can buy from most hardware stores.















O Desenho Paramétrico é aqui ensinado duma forma prática e divertida, mais uma vez um Vídeo de Maker's Muse, e ainda tem lá Links para Tutorials, na descição:







How to Draw a Geneva Mechanism in Fusion 360
Maker's Muse

In this video I'll show you how I drew the Geneva Mechanism in Fusion 360. Once you get your head around using constraints (relations) and construction lines you can create very complex, adaptable sketches with ease!















Não resisto a cá pôr este pequeníssimo vídeo, montei esta minha Impressora 3D, e ei-la a cantar...
Não aconselho ninguém a comprar Kits da China, foi um Pesadelo montar este bicho, curioso, os Vídeos são uma confusão, mas incrívelmente, têem uma boa série de Imagens 3D passo-a-passo!
Haja paciência
Quando convencer a placa, uma má imitação do Arduino, a fazer qualque coisa, a história continua...

Espero que gostem, deixe aquele like bacana e compartilhe com seus amigos nas redes sociais, um grande abraço e um beijo no coração.













Eis com fazerem uma Ventnoínha estilo Dyson, porque está calor cmo sei lá o quê, e assim não levam com o "martelar" tão próprio das Ventoínhas tradicionais...






3D Printed Portable Bladeless Fan
WhyyNot

"A bladeless fan (sometimes called an air multiplier) blows air from a ring with no external blades." Dyson is a very popular company who has utilized this technology to make a quieter fan that performs better than more traditional versions. A common misconception is that "bladeless fans" are not actually bladeless. Instead of being external, a small fan is located in the pedestal and forces air out of a thin ring.
Here I'm building a very basic model which won't perform nearly as well as the Dyson models, but will be a small fraction of the price. This small model is easily portable and can be refreshingly used in a vehicle or outside as well as inside.

Pode-se agora medir o Raio dos Cantos circulares de algo que queiram reproduzir, ou duplicar, com esta gigajoga impressa em 3D! 
Cortesia da JayconSystems, é perfeita para "reverse Engineering", e conserto, por substítuição, de peças que já não se fabricam mais:







How to Measure a Corner's Radius Using a 3D Printed Tool
JayconSystems

The world is filled with millions of different objects all with different shapes, angles, lengths, heights, widths, surfaces, depths, volumes, geometries, etc… You get the point. There are many different ways of measuring all of these different objects. Here we will focus on measuring rounded corners on physical objects. This can be a difficult task without the right tools.
Our Mechanical Engineering Team at Jaycon Systems creates, reverse engineers, and tests hundreds of hardware projects every year, so in order to make our lives easier, we came up with a simple 3D printed tool to help measure the various radii (believe it or not that is the plural of radius) of the things we work on. We hope we make your life easier as well by making these files available to the public.














Cá temos uma Fresa CNC, mesmo a puxar pró grandinho, que pode estar mesmo a calhar para alguma Oficina de Garagem, por aí...
Um Sonho realizado, para muitos.




Build Big Cnc at Home 3x2m
VladoM

So why this should be of any interest of yours?
This machine was build without any special tools, basicaly drill, clamps, saw and meter would do. Of course there is more, like drill bits or, taps... but i built this one without having even a proper table.
Machine was designed to use as few part as possible and to be as precise and strong as possible, also speed was desirable as i wanted to use it with plasma, then i also wanted to be able take the machine apart, build it from localy available components so no premade table parts are needed to make the build, and after all this this machine still needed to be nice and square. Weight of some components and force distribution was also thought over.
At the end here are some realy interesting solutions for problems i delt with, worth to check out, at least i believe so.

The $1 Pocket Microscope - Explore the World Around You at 80x and 140x!
anisotropy

Microscopes let you explore the world around you at a small scale. With this $1 3D printed microscope, you can see tiny things in amazing detail! Looking at insects, plants, and even dirt close up can be fascinating.
I've already seen firsthand how impactful inexpensive tools for scientific exploration can be. I started this design about two months ago when I wanted a cheap microscope to bring with me to Liberia, where I participated in a program training science teachers. Some of the teachers, particularly those from rural areas, had never used a microscope before. Using this very Pocket Microscope was the first time they saw the microscopic world firsthand!

Low-cost desktop injection moulding
Janie Barrett

Low-cost desktop injection moulding - here, Mitchell Brown from VERT Design, explains how they did it using Asiga's desktop 3D printing solution ...
Our product design company was engaged to develop a variation of a hose clip that is used on a high speed production line. The product works through the use of an integral hinge and flexible clipping geometry.
Traditionally we would test the design through the used of SLS 3D printed models, however, the results achieved were not accurate. We required the geometry to be proven in the actual production materials, which in this case was injection moulded polypropylene
Through the design phase, we developed multiple iterations. Eventually this was short-listed to two possible concepts. Producing a prototype tool in steel or aluminium would have cost many thousands of dollars and taken a minimum of 6 weeks. We turned to 3D printed tooling as it was faster and cheaper.

The Easy Way to Design Gears in Fusion 360
Desktop Makes

One of the first things I ever made from a 3D printer was a gear. But it wasn't just any old gear. The beauty behind this gear was that it was a replacement part for the very printer that was making it. This still blows my mind to this day. I love printing gears and still get excited about this new world that 3D printers have opened up. The problem is that designing gears have always been a bit of a challenge for me. That is until I learned what I'm about to teach you.
In the last step I also include a video demonstrating the entire process.

Maker Reinvents Electric Spinning Wheel & Rolls Over Kickstarter Goals By 979%, Then 1,744%
Lisa Horn

If you think knitting and crocheting are only for grandmas or that macramé and woven wall hangings were just a fad in the 1970s, think again. Thanks in part to festival fashion, yarn arts are alive and well…and growing.
In fact, 38 million people knit or crochet according to the Craft Yarn Council—including celebs such as Cameron Diaz, Daryl Hannah, Julianna Margulies, Sarah Jessica Parker, Julia Roberts, Hilary Swank and Vanna White. And the Association For Creative Industries says that the U.S. creative products industries are valued at $43 billion.
There are more craft-related blogs, websites and tutorials than ever before. YouTube has 12,000 woven hall hanging videos, 400,000 macrame how-tos, 2.6 million knitting tutorials and 3.6 million crochet trainings. You could spend days on Instagram getting inspired by #bohemianstyle, #yarnlove and #makersgonnamake. Pinterest is filled with DIY yarn craft ideas. Craftsy offers lessons in 18 types of creative arts.
While these kinds of artistic expression provide a creative outlet, reduce stress, improve mood and build confidence, many makers are finding there is a business opportunity as well. On Etsy, there are 13,000 listings for woven wall hangings, 228,000+ macramé items, nearly 700,000 knitted products and 1.18 million crocheted designs.
That’s a lot of yarn.

Build Your Own Electric Car!
bennelson

(AUTHORS NOTE, July 9, 2017)
Hi Everyone, there' been a lot of views on this project lately! Thanks for coming by to read through it! Much has changed since I originally built this car, including the fact that there are a LOT of great commercially built electric cars available for sale, including used at good prices. When I built this car, pretty much the only electric car available was the $100,000 Tesla Roadster. Now, I'm driving a used Mitsubishi iMiEV electric car and power it with my Solar Garage! Please take a look at my other Instructables and at 300MPG.org for the latest on my clean transportation adventures!)

How to Make Playdough (Play-doh
canida

Playdough (aka Play-doh) is easy to make at home, and fun for kids of all ages.  Here's how to make your own non-toxic toy with custom colors and fragrances.

This is the classic method that involves a bit of cooking on the stovetop - I prefer it because cooked playdough has a better texture than uncooked varieties.  If you want the kids to be able to do it all themselves, try this uncooked playdough recipe.

Warning:  Keep away from dogs and other pets.  Playdough smells like people food but contains lots of salt, and a hungry dog can eat enough to cause a dangerous salt imbalance.

Benchtop Disc Sander
tomatoskins

Disc sanders are extremely useful tools used for rough shaping wood. When I needed a dedicated sander that could take off a lot of material at once, I was less than impressed with what was available. After not finding any disc sanders with the size and power I wanted in my price range, I started thinking of other options. Looking at what others have made in the past, most did not include a tilting work surface. This was a great design challenge that turned out better than I could have hoped!
If you are looking for your own disc sander and not impressed with anything available for the price, a homemade disc sander may be for you.

















Não que os Inventores precisem de ajuda para inventar, até inventam sem querer, mas de certeza que precisam de aprender a fazê-lo duma forma mais organizada!

Por isso, cá vai uma série de Instructables, que formam um verdadeiro Curso de invenção:




 





INVENTION CLASS

This class will focus on the process of invention and how to create quality designs (products specifically) through a straightforward series of steps that provide – even for those who consider themselves to be uncreative – a path to new, innovative, well executed ideas.
Using empathy, iteration, imagination, and a dedication to problem solving (let your inner Sherlock shine!), you’ll follow along with me as I design a portable smartphone amplifier to illustrate the concepts I’ll be covering in each lesson.
Inventing is by no means a mindless paint-by-numbers process, but a systematic way of thinking – both in and out of the box – to create meaningful products that solve problems and have the potential to change lives for the better.
Let’s design a thing!
