PVC para tudo! E uma transmissão em 3D, mais uma Forja Eléctrica, e um Congresso de INVENTORES!

Um achado, do nosso amigo José Abrahão, eis como podem fazer, por exemplo, um abrigo para a Mota, ou mil e uma coisas mais, com tubo de PVC!
E ainda lá encontram acessórios difíceis de encontrar...
É bom!



www.PVCPLANS.com 

FREE plans. Make a GREENHOUSE, Pastured Poultry Pen (Chicken coop house), Cold Frame, Quad, ATV, Golfcart Carport mini garage shed, Banner Holder, row covers and more structural buildings out of PVC pipe. See pictures of other's projects and find links to retail stores and wholesalers with hard to find funiture grade PVC fittings and clamps. 








Dica do nosso amigo Peter Smith, não há limites, agora, para os Modelistas, com a Impressão 3D...
Até podem fazer um Modelo funcional duma Caixa de Transmissão, como se não fosse nada de mais!



3D Printed Working 5-Speed Transmission for a Toyota 22RE Engine 

While we see plenty of very impressive 3D printed objects complete with plenty of moving designs, few building projects are more inspiring than Eric Harrell’s PLA working replica of the Toyota 4 Cylinder Engine 22RE. To refresh your memory, Eric’s recreation is a reverse-engineered engine that has been scaled down to 35% of the original size, as this was simply the largest possible option for his own RepRap Prusa 3D printer. Assembled with magnets, the 80 different components probably took up about a whole 1KG roll of PLA filament and took more than 34 hours to completely print. ‘It's definitely a challenge for you and your printer,’ Eric said.
But that was last January, and now Eric’s already back for more. Going for a larger and more complex model, he has now 3D printed the four-wheel-drive gear box for his previous model: the 5 speed transmission Toyota 22RE. It’s a fully working miniature replica of that matches his previous project, complete with a reverse gear. Like the engine, it’s not for the beginners. ‘This model is more complex than the engine,’ he writes, though it is in fact far more complex to assemble.










 ...E a pedido de várias famílias, e para gozarem de paz com as vossas adoráveis Patroas, cá vai esta Forja para derreter Alumínio, que como é Eléctrica, não produz toda aquela Fuligem & Fumaça que tanto desagradam ao Mulherio...
Com alguma razão! 
LOL


   
Electric Furnace
TunerFreak

The main reason I chose to convert to electric over any of the other alternatives that involved burning some sort of fuel is efficiency. Greater efficiency leads to lower operating costs and greater melting capability. Burning charcoal, wood, propane, or any other fuel sources require that many conditions be met before optimal efficiency can obtained. This is because burning is a chemical reaction and therefore requires that the optimal stoichiometric ratio be met in order to burn the fuel as efficiently as possible. This makes optimizing the furnace complicated and requires tools that most do not have access to. In addition, even when the optimum ratio is met, there are still bi products that are released that aren't heat. These bi products serve no purpose and therefore decrease efficiency. This brings us to another problem, expelling the exhaust gases. Because the bi products of combustion must be released in order to continue the process, we also wind up releasing heat in that process.









... E finalmente se vai realizar um Congresso de Inventores em Portugal!

X-Carve? E o Seebrick, uma Cãmara de Inspecção, Uma Mesa de Vácuo, e Moldes para tudo.

Da Inventables, vem-nos esta nova Fresa CNC, a XCarve, que podem configurar à vossa maneira, tanto no tamanho, como na potência da Fresa:


X-Carve: Inventables targets makers, startups with unveiling of the X-Carve
John Carpenter
Chicago-based design supplier Inventables took another step into the digital manufacturing sector Tuesday with the launch of X-Carve, a customizable computer-controlled milling machine.
The new model allows small makers to choose from a variety of features, from the size of the machine to the power of the cutting tool. The company says it can carve precision parts and other designs from plastic, wood and metal.
Inventables CEO Zach Kaplan ⇒ said companies making thousands of units of a product will still look to outsourced manufacturing options. He said the X-Carve targets hobbyists as well as maker startups that don’t yet produce the volume of bigger companies.







Seebrick é o resultado de se reunirem Mentes à volta de problemas concretos, do Terceiro Mudo, leiam isto para acompanharem esta Saga de ajudar a valer:





Starting small, aiming big

RS Components and Practical Action came together in a hackathon aimed at providing support to third world countries.

Three teams were brought together, made up of highly regarded engineers and designers including Ortis Deley from the Gadget Show, Adrian Bowyer, founder of the open source RepRap project and Jude Pullen from Design Modelling. Their aim was to produce an eco-friendly project that would generate electricity in third world countries. The teams had two days to plan, construct and present their ideas on how to enhance the lives of those living in poverty.

The first team, Maxwell, developed a way of producing power from the excess heat from cooking. The ‘SeeBrick’ that the team developed is made of clay and uses low cost metals (copper & steel) for wires. Its main function is to utilise the Seebeck Effect to create a voltage. Relying on the temperature difference to generate power, this brick is ideal for placement near a fire. The SeeBrick can generate enough power to light 15 LED lights. This innovation could supply a family home with enough light for reading, studying or even to charge a phone.

Large Vacuum Former 

fizzPOP-TheBirminghamHackspace

We had a requirement for a big vacuum former, as many of our members were interested in costume making and cosplay and needed to be able to make torso size "armour" etc. so we first took look to see what was available commercially and soon realized anything we could afford even second hand would be way too small for our needs. Having decided that our only option was to build our own we scavenged the internet for ideas and came up with a basic design that evolved into the machine we have made.

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.

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.
