Façam a vossa Impressora 3D! E magia LED, Acabamento 3D, Peltier para Câmaras, e Craftware

Se têm acesso a uma Impressora 3D, dalguma Fablab, ou de alguém que conheçam, podem, em troca dumas Bobinas de Filamento extra, e mais uns Trocados à parte, ter esta bestial Base CNC, que pode ser uma Impressora 3D, uma Fresa CNC, uma Cortadora Laser...~
Ou as três, com 3 cabeças de encaixar!

É bom!



Cheap Scalable Arduino CNC (Plotter, Mill, 3D Printer...)

mendelecha1 
In this Instructable I'll show you how to make a cheap scalable CNC machine controlled by Arduino. My printer has a usable volume of 1500x1000x200mm. It will provide a computer controlled plate where you can add any kind of tool for your application: laser, mill, drilling machine, 3D printer head, pencil…
THIS IS MY FIRST INSTRUCTABLE, PLEASE VOTE IT IN THE First Time Author Contest!!!
In order to maximize customization capabilities and reduce costs:
Most parts are 3D printed
Open source hardware / software
Tube profiles work as Rails
If you are looking for a CNC but don’t want a single purpose thousand-dollar machine, this is your project!!
Be sure to watch the video above, and if you like it please consider subscribing to my channel which has been recently created and will be updated with new amazing projects.
Before starting you should know the usable length, width and height you want for your machine. The less heigth (Z) the better.
This project is based on Allted's design CC BY-NC 3.0 










Algo fácil de fazer, mas espectacular, é este Globo LED que podem fazer, e ter a satisfação de criar, sem dar cabo da cabeça...
Claro, isto vai-vos convencer a mererem-se em mais Projectos, mas há Vícios bem piores! LOL





Make Your Own POV LED Globe

GreatScottLab 
In this project I will show you how I combined a couple steel pieces with an Arduino, an APA102 LED Strip and a Hall effect sensor in order to create a POV (persistence of vision) RGB LED Globe. WIth it you can create all kinds of spherical pictures or even letters which is a definite eyecatcher. Let's get started! 












Uma Impressão 3D para uma Prova-de-Conceito, não precisa de ter um acabamento especial, mas há alturas em que o Aspecto vende uma ideia.
Para isso, ou seja lá para o que for, Montras, festas, Modelos para Arquitectura, etc. vejam bem aqui, como obter um Visual de fazer chorar as Pedras da Calçada...

Guide: How to Finish 3D Prints

brett 
While I have 3D printed hundreds of designs over the years, not once have I taken the steps to finish a single print. There are plenty of videos and articles covering the process but they are often a general overview and leave out small but important bits of information. For someone inexperienced like myself who prefers to follow explicit instructions, the artistic process can be a rather daunting task. Unfortunately I purchased my 3D Printers for costume and prop design and can’t leave them unfinished forever, where this guide will cover my successful, albeit awkward adventure into the task of post processing 3D prints. 













Não sei se não se poderá usar isto para cabeças de extrusão das Impressoras, ou mesmo para os Computadores sobrecarregados dos Engenhocas, mas já para estas Câmaras espectaculares, é uma Maravilha...

A Impressão 3D depende em tudo duma boa traducção dos nossos belos sonhos em 3D, em GCode que produza algo de jeito.
Sem isto, é só Filamento estragado, acreditem que sei do que estou a falar...
Por isso, estes Programas Grátis, que encontram na Net, são tão importantes!







CraftWare
Overview 
CraftWare is a FREE, fast, easy-to-use slicer software that converts your digital 3D object into a .gcode toolpath format understood by most 3D printers.
CraftWare primarily works as a slicer for solid 3D digital objects, but it is also an excellent tool for many other tasks. You can interactively manage your prints, thus reducing build time and finding the optimal build supports. CraftWare also utilizes the most impressive gcode visualizer on the market; this allows you to see each print layer-by-layer, from any angle, easily allowing you to detect any places that you may want to modify before printing. It is basically like seeing a finished print in front of you before you press the start button.
CraftWare utilizes dual channel communication for real time interaction between the software and the printer -just another great tweaking option.

Robots de Papel! E Inventores de Drones, um Móvel para as Ferramentas, Electricidad de pesos, e um fidget!

Robots de Papel! 
Isto é muito bem achado, da Industry News... 
Robots que se movem como Minhocas, e podem mover-se por aí, muito mais baratos, pequenos,  e fáceis de fazer.
Não vai passar muito tempo até que se faça disto por toda a parte, e nem sei se não vai alguém fazer uma espécie de micro Stepper, e daí uma micro-CNC! 





Researchers Make Robots Out of Paper 
A team of researchers from the University of Illinois Department of Mechanical Science and Engineering has made a pair of crawling robots, Peri and Poly, out of little more than a sheet of paper, a few 3D printed parts, and a handful of screws.
The researchers used origami paper folding to create cheap robots that move like earthworms.
Poly is 51 mm wide and uses a pair of origami towers that expand and contract when twisted to make the worm robot crawl forward. The robot has directional feet made of hard plastic and rubber. The 3D-printed toes allow the robot to slide forward while the rubber heal stops it from backsliding. This particular example of bio-mimicry was inspired by the setae on earthworms.
Peri is more than twice the size, and fully mobile. Peri is 106 mm wide and runs on batteries unlike the Poly, which is tethered to the power source. Peri also uses on-board controllers to navigate. 











Podem pôr a Míudagem a fabricar Drones, aprendendo técnicas que os vão potenciar para um futuro emprego.
É bom!
Vem com mais de 16 Missões, mas o que é SÓ isso para um Engenhocas? As aplicações são INFINITAS!
MUÁHÁHÁHÁHÁ!

Da Página da Facebook, Zink, vem esta ideia muito bem-vinda, usar o velho mecanismo de pesos dos Relógios, para produzir electricidade para iluminar uma casa, em zonas sem Rede Eléctrica.
Muito Bom.





The Problem
 
Over 1.2 billion people globally have no access to electricity and millions more have an unreliable supply. Instead they use dangerous, polluting and expensive kerosene lamps for light.
A typical kerosene lamp is made by taking an empty bottle or tin can, putting a wick in the middle, filling it with fuel and lighting. Using kerosene for lighting is extremely inefficient, dangerous and expensive, and it has extensive health and environmental drawbacks.

How It Works
Combining kinetic and potential energy, GravityLight works by connecting an elevated weight — filled with rocks or sand — to a pulley system that slowly powers a generator as the weight falls to the ground. 











Para se divertirem um pouco, fiquem com esta ideia, que é uma boa maneira de renovarem a Novidade dos Fidget Spinners:






Electromagnetic Fidget Spinner Accelerator
tanner_tech  
Fidget Spinners are little plastic toys with a bearing in the center. They are fun for a little bit, but get boring after a while due to their slow spinning speeds. There are ways to make them spin faster, but these methods involve using a bulky air compressor or an expensive can of compressed air. Luckily, I have found a cheap way to accelerate these fidget spinners to extremely high speeds with the power of electromagnetism. You can even hold the spinner in your hand while you accelerate it! I have clocked a spinner that is spinning with this accelerator at speeds up to 1440 RPM, that is fast. You can build this accelerator too, it is really cheap and really simple to build.

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:

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.

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.
