Papercrete! E a Turbina 3D, ligar Micro-controladores pelo telefone, Fita de carbono, soldar sem electricidade, e um Gancho à maneira

Papercrete!
Uma mistura de Polpa de Papel e Cimento, e faz-se de tudo um pouco com este Material fácilmente moldável...
Facilita a vida, quando se faz, por exemplo, uma Oficina, no Quintal e metade do Material é Papel que iria pró lixo.
Tomem nota da Maquineta de que se fala neste Artigo embaixo, porque acho que se podem fazer muitas mais coisas, com essagigajoga, sabe-se lá se não se usa para mil e um fins no Quintal, como preparar a uva pró Morangueiro, e transformar a Mata em lenha:


 

Everything You Need To Know About Papercrete

Expert Prepper 

For all those who aren’t much familiar with it, Papercrete, in essence, is a type of fibrous cement (cement with a certain proportion of fiber in it). Because of its unique composition, papercrete is lightweight and strong, hence a perfect fit for a multitude of tasks. But more on that later – let’s first begin with,
The Ingredients in Papercrete

The ingredients that make papercrete can vary wildly based on what it’ll be used for. From cotton, wool and hemp to paper (wood fiber), flax and jute, different fibers can be used to make papercrete. For example, papercretes for building the walls of a house are usually composed of basic formula of cement and plastic. However, for any load bearing platforms or walls, a small amount of sand can boost compressive strength even further.

The addition of fiber to the cement results in a much stronger mixture – more or less the same way as the addition of fiber fibers boost the strength of fiberglass.

Researchers create world's first 3D-printed jet engines

Ben Coxworth 

Working with colleagues from Deakin University and CSIRO (Commonwealth Scientific and Industrial Research Organisation), researchers from Australia's Monash University have created the world's first 3D-printed jet engine. While they were at it, they created the world's second one, too. One of them is currently on display at the International Air Show in Avalon, Australia, while the other can be seen at the headquarters of French aerospace company Microturbo, in Toulouse.

Cellular Connectivity Comes to Microcontrollers With The Spark Electron

David Scheltema

Meet Electron from Spark, the new board that puts GSM cellular connectivity directly on the microcontroller.
With its onboard cellular antenna, this diminutive board will offer a huge range of deployment options and alleviate the hassle of using a custom cellular breakout board with your micro controller projects. They’re offering two versions, with either 2G or 3G connectivity.
It thankfully also reduces the frustration of dealing with mobile carriers — more on that in a moment.






A Fita de Fibra de carbono serve para uma data de usos invulgares e vejam só estes 6 usos, para sobreviver no Mato:



Carbon tape to survive. 6 in 1

What is your the minimum kit to survive? Maybe a big knife and reliable lighter? We found one more thing - carbon fiber tape.
Using one piece of carbon tape you can make:
1. Water filter
2. Gas-mask
3. Torch
4. Oil lamp or stove
5. Care of open wounds and burns
6. Fiery sign

How to Solder Without Electricity (or a Soldering Iron)
DIY Hacks and How Tos

Soldering is a valuable skill. There are a lot of situations where the ability to repair or modify electronics can really save the day. But most people don't carry a soldering iron around with them. And even if you did have a soldering iron, there is a good chance that you might not have access to electricity.
So today I am going to show you how to solder using random objects that you might find lying around (and a little bit of solder).








E eis um Gancho de Génio, agarra obectos no chão, e serve para apanhar de tudo um pouco, ou atirar a Àrvores e telhados:







High Performance Grappling Hook
Mrballeng

We carry a lot of different things. Sometimes we drop them. Instead of leaving your everyday carry items out of reach, get your grappling hook!
This is the sequel to the original grappling hook I posted. The first one worked great but didn't stow so well. Here's what I'm working on now. It's a cross between a mechanical claw and grappling hook. When it touches down, gravity pushes the jaws open. Lifting it closes the jaws around your prize. Now I feel better about all the quarters I've lost in claw machines.
This is funding on Kickstarter right now of you'd like check it out. And for all you DIY folks, once the project closes I'll attach the file in step 4.

Hobbyist creates working League of Legends zapper pistol

Ben Coxworth

Laser weapons hobbyist Patrick Priebe is no stranger to building functioning versions of guns from video games. Recently, he received a number of requests to create something from the game League of Legends. The result, the Jinx character's zapper pistol, could certainly be described as "electrifying."
The zapper features a rosewood grip, white and blue LEDs in the barrel, and blue LEDs farther back. Other parts are made from gold-painted aluminum, and gold ol' steampunky brass.
Pulling its trigger activates a balloon-popping/hole-burning 1.6-watt blue laser, along with a "lightning-in-a-jar"-type feature in the rear. The latter is made from a flash tube of the type used in studio photo flashes, filled with xenon gas. When voltage is applied, the arcing electrical "streamers" are the result.





...E, acho que isto foi Dica de Eddy de Ridder, como os Engenhocas têem tantas hipóteses de ganhar o TotoLoto, como qualquer um, podemos sonhar com esta Fresa, e Impressora 3D, assim mais para o...
GIGANTE!
Teriam de nos arrancar à força da Oficina, com um Bichinho destes, lá...

Artis develops giant KUKA robot, a 100 cubic meter CNC machine & 3D printer in one 

Alec

You might not think about it when toying around with a conveniently-sized desktop FDM printer at home, but 3D printers come in all shapes, sizes and price ranges. But while we come across large and unusual 3D printers all the time, even we were very amazed by the KUKA Quantec Ultra machine, developed by the Berlin-based construction and engineering company Artis Engineering. While exceptionally large, it’s especially amazing for its dual nature: it's a CNC milling machine and 3D printer in one.
Artis Engineering is an interesting company that really illustrates how continuous innovation is key to success. Established in 1994 as a producer of classic cabinetry, they have since grown to a company employing 30 people and specialized in creation unique shapes, cabinets and setups for museums, art exhibitionsm medical practices, trade fair stands and so on.

Injecção de Plástico, da Impressora! E forjar uma Faca, Micarta, e o CNC Arduino

No capítulo das ideias que todos goataríamos de ter, eis como fazer peças, com a Impressora 3D, ou pequenas, ou demasiado detalhadas, ou ambas as coisas...
Por exemplo, imprimam em 3D uma peça, e aperfeiçõem do Detalhes;
Usem a peça para fazerem um Molde em Silicone;
Injectem lá o Plástico, da Makerbot...
Já está.




Turn Your 3D Printer Into an Injection Molder
Matt Stultz

One of the issues with using FDM/FFF 3D printers is the ability to print small objects. The extrusion widths of the deposited plastic are just too large to capture the fine details in a miniature print. 
Molds, on the other hand, can capture every detail of an item they are trying to create. The professional world uses injection molding when they want to create small detailed parts. 
Now, Instructables user BFK (Bruce Kinsey) has created a great guide on how you can do the same with the help of your 3D printer. 







Eis um método facílimo de forjar em Metal, neste caso, uma Lâmina de Faca, mas pode ser qualquer outro objecto...
Com Ossos de Choco!
Chocante. LOL
...Chocante, de tão boa ideia que é!


Cast a blade
PowellMade 

When I was a kid my father used to make jewelry. I watched him make
amazing things and I could always count on him knowing how to do something that would help me with my projects.
One day I asked him to make me a fish necklace. I was surfing at the time and everyone was wearing something interesting. Dad pulled out some cuttlefish bone and asked me to draw what I wanted on it. I drew a fish and then watched him turn my picture into a 3d object. He used a fine tipped oxy acetylene torch to heat up a bar of silver and drop forge it into a mould.
The result was so beautiful! The fish had a timber-looking grain running throughout it and it was timeless because of the old-school feel. I never forgot that day and have always wanted to try it again. Well here we are! Time to forge a letter opener with a timeless feel. This knife may not be practical as a bush-bashing, hair-whittling kitchen knife, but as a work of art it will certainly have people asking how you created it. I hope you all enjoy and get the opportunity to try this at your own home.







Micarta! 
Parece um prato Japonês, mas não, é uma técnica do século passado, que consiste, muito simplesmente, em embeber Tecido com uma Resiña, prensá-lo, e produz-se assim uma Placa.
Sim, como a Fibra de Vidro, mas esta versão é mais para o Artístico, devido aos efeitos da Maquinação em camadas de Tecido de cores diferentes.
Mas poderá também servir para N outros fins!






How to make homemade micarta
oldanvilyoungsmit

Here is a short video showing how I make my homemade micarta that I use in knife handles quite often. One tip I didn't mention in the video was to use superglue to finsih the micarta. Sand it to 320 grit, rub it really well with a green scotchbrite pad (hot tip- those with dremels, chuck the scotch brite in the dremel for fast polishing). coat the handle with 5-6 coats of thin superglue, sand it at least to 320, use green then white scotchbrite (in the dremel for speed). that should give you a nice finish. attached are some examples of my homemade micarta. First two pics are a girly knife handled with pink and purple denim micarta. Third and fourth is a kitchen knife I made with the micarta in the vid, and the fifth is some with bright orange cloth. sixth is blue jean and pink jean (this was my sisters christmas present) . 







E acabamos, por hoje, com mais este Projecto para fazerem a vossa própria Máquina CNC, com o Arduino, e pouco mais:


Arduino CNC
JohnnieT

Hi, this is my first instructable and I hope to do more.
This project was for 'Creative Electronics', a Beng Electronics Engineering 4th year module at the University of Málaga, School of Telecommunications.
It's a cnc using Arduino UNO R3 , GCode Sender and GRBL. The cnc is made of wood thanks to the help of my father. It has taken us many hours to do the mechanical part however the electronic part is faster to do, but is very gratifying. I based my project on these videos and I have received much support from the author of the first video.

Build Your Own Toys with ThinkFun’s Maker Studo
Kathy Ceceri
As I mentioned yesterday, the big theme of this year’s Toy Fair in New York is “joining the maker movement.” But to qualify as a genuine maker toy, a plaything should meet some basic criteria. One new series of kits that fits my definition of a maker toy is the Maker Studio Construction Sets from ThinkFun. The building sets are a departure for ThinkFun, which is better known for their logic games like Robot Turtles and Rush Hour, but completely in keeping with their theme of brain-building and hands-on fun. Designed by engineers David Yakos and Parker Thomas, the three Maker Studio sets — there are Gears, Propellers, and Winches — include struts, connectors, and moveable parts like wheels. It’s up the user to find a suitable body, and the sets encourage kids to look for recycled containers and materials to build out their projects, like the mac-and-cheese box racecar chassis.

Regulem uma Voltagem determinada, e quando um circuito tiver uma Voltagem maior que ela, esta simpática Gigajoga da Littlebits acciona luzes, motores, etc.
Mais uma boa ideia da LittleBits:
threshold
SHORT DESCRIPTION
Think of the threshold as a toll booth for signal passing through your circuit. The threshold compares the incoming voltage coming from the bit snapped before it against the voltage amount you’ve set by the threshold knob. If the incoming voltage value is greater than the selected voltage, the threshold will allow the signal to pass and activate any bits (lights, motors, etc…) following it. If not, then nothing will be activated. Use it to make any sensor module into a trigger module!




 



 ...E o que é uma óptima notícia, e bem que precisamos de boas notícias, descobriu-se agora, como é que um ingrdiente do Azeite Extra-Virgem, que Portugal produz, do melhor que há, mata as células Cancerosas!
O oleocanthal, é esse o nome do tal Ingrediente, vai ao compartimento, nas células, que contém os desperdícios,e fura-o, desencadeando a auto-destruição das Células cancerosas, por isso, é de esperar mais esta Arma no Arsenal da luta contra o Cancro...




Olive oil ingredient leads cancer cells to their death
Nick Lavars 

An ingredient found in extra-virgin olive oil called oleocanthal has been known as a compound capable of killing a variety of human cancer cells, but how this process actually played out was not understood. Now, a team of researchers has uncovered not only how oleocanthal destroys cancer cells, but that it is able to do so while leaving healthy cells unharmed.
Paul Breslin, a professor of nutritional sciences at Rutgers University, had thought that oleocanthal killed the cancer cells by targeting a key protein in cancer cells that triggers apoptosis, a process that sees dangerous or damaged cells self-destruct by upsetting the balance of ions in the cell membranes. In investigating this theory, he teamed up with David Foster and Onica LeGendre, two cancer biologists from New York City's Hunter College to more closely examine the process.

E só porque sim, cá vão de embute, dois Instructables impecáveis...
Este, como fazerem uma Oficina num Móvelzinho articulado e cheio de truques, com rodas e tudo!



Complete workshop in a shelf
sachsie

Most Instructables projects require you to have some basic tools and a workshop available - unfortunately, most people do not have the space for these bare essentials available. Just like me.
My girlfriend and I live in a moderate sized apartment for some years now. We have got a spare room that offers sufficient room for our hobbies. Now we expect a baby and this room is assigned to it. As a consequence, I have to move all my tools in a tiny compartment of an IKEA shelf and have to find a new workspace too.
I approached this problem, by building a compact yet solid frame made of low-cost aluminum extrusions. It offers some very handy features:
  • storage space and organization for my tools
  • frame acts as a multi-purpose workbench. It offers:
    • a drill press
    • a router table
    • a bench vise
  • Concept is very flexible and may find further extensions.
Everything is designed to fit the size of the compartment. Total costs of this project are about 150 EUR.

UPDATE! Backpacking Gasifier Stove
Quark-

Hello, this is Quark- and I am here to show you how to make your own TLUD (Top Level Updraft gasifier stove), and you can look them up at http://www.build-a-gasifier.com/gasifier-wood-stov.... They are essentially a stove that burns the fuel not once, but twice. The base thermos holes allow air into the fuel, while the top holes allow preheated air down into the stove to basically burn the fires smoke. I recently learned about the design while looking up specification for the popular Biolite Campstove, a design which I sought to make. Only then did I learn that it was a gasifier, and the rest is history. They are often used in third world countries, due to the fact that they are incredibly cheap to manufacture and are 10x more efficient than just a plain fire. Because of the double-walled construction, it is easy to use a simple food thermos to make one of these beauties. Enough talking, Onward!
