Dobrar Metal? E extraír fumos, 3D do Smartphone, 507 Movements, e uma Prensa em Alumínio

Uma Ferramenta para dobrar metal, com qualidade e precisão?
Faz jeito, faz...
E podem agora ter uma em casa, feita de propósito para quem não tem muito dinheiro livre, mas quer resultados de qualidade:




Homemade Roller Bender
Make it Extreme 
The main problem that people, who are occupied with doing various metallic projects and generally constructions, face is the bending of metallic pieces. The reason that this problem is arisen during these projects is because the metallic pieces need a lot of pressure, strength as well as accuracy to be bent. There are many machines to be used to achieve this but the cost is high. Although, the metal roller bender has been already made once by the ‘make it extreme’ team, the particular construction was not affordable by anyone as more specialized machines were needed to be made than the ones that can be found in any home. Therefore, this our 56th construction is more user-friendly to everyone, is relatively affordable, is extremely useful and it will fill with feelings of joy and satisfaction the people who want to spend their time productively. 













Fumos, são um problema, tanto com a Soldadura, como em muitos processos, na Oficina.
Eis uma ideia bem bacana, que sai barata, e vos poupa na Saúde, também:







$5 Powerful DIY Fume Extractor
geekrex 
I love making projects from scratch whenever possible, so soldering comes in the process.But soldering needs to be done in a well-ventilated Environment or a Fume Extractor should be used.
But Why is soldering so dangerous?
Flux generates the visible fumes seen during soldering. Exposure to rosin can cause eye, throat and lung irritation, nose bleeds and headaches. Repeated exposure can cause respiratory and skin sensitisation, causing and aggravating asthma. Rosin is a serious occupational health hazard.
But Fume extractor are really expensive like 70$ which beginner like to skip because of the price.
In this instructable, I will share what I used for so many years.This project cost around 5$ but works like a charm.
Not only it can be used for soldering only it can also be used for 3D Printing ABS, as it fumes and also toxic in nature. 










Com este App, o Makerpad, podem imprimir em 3D, fazer um Scan 3D, Objectos 3D, e até cortar por Laser CNC, a partir do vosso Smartphone!
O que é uma forma porreira dum Engenhocas se poupar a muitas dores-de-cabeça...





“MAKERPAD” PLATFORM ALLOWS BEGINNERS TO 3D PRINT THROUGH SMARTPHONE
Peter Smith 
Purdue University’s researchers in Indiana have collaborated with the National Science Foundation to start an innovative platform that enables your smartphone to assist in 3D printing, allowing you to create some unique designs. This new platform is known as Makerpad – an inventive and advanced platform specifically for beginners. The patents of this platform are presently pending by the Purdue Research Foundation’s Office of Technology Commercialization.
Karthik Ramani, project leader of this venture said that manufacturing and product design are the purviews of professionals and enterprises like artists and engineers. On the other hand, Donald W. Feddersen, a professor of Mechanical Engineering at Purdue University explained that many people have ideas but only a few of them have guts to implement those ideas into a reality. This is actually a waste of available creative human resources and the economic prospects of the world economy.
This platform can even be used by amateur users to create 3D prints, 3D scans, 3D models and laser cuts. With the network accessibility and free technology available, anyone can easily attempt to become a designer. However, 3D printing involves some fundamental skills as well as tools. Hence, many designers are simply not capable of using 3D printing technology effectively. But with the help of this platform, “Makerpad,” users can now easily 3D print several designs.

Quando se depararem com um problema mecânico, é sempe bom terem uma fonte de Mecanismos que poderão resolver o que vos está a empatar a criação da Engenhoca...
Já vos falei aqui duma data de Sites com Mecanismos, como os Museus Reuleaux, uma Colecção de Animações 3D, e os Vídeos de Thang, mas pode-se dar o caso de que nem nesses Sites esteja o que precisarem, por isso, cá vão mais 507 Mecanismos, neste Site, 507 Movements: 




Welcome! 
This is an online edition of the classic technical reference Five Hundred and Seven Mechanical Movements by Henry T. Brown.
This site contains the original illustrations and text from the 21st edition of the book, published in 1908. It also includes animated versions of the illustrations, and occasional notes by the webmaster.
The animated versions are not yet complete. They are identified by color images in the thumbnail pages. To keep up with developments on this site, use the Twitter Follow or Facebook Subscribe links below.
Animation system
The animations are implemented with a custom JavaScript library, which uses an HTML 5 Canvas element. You must have an up-to-date web browser to view them.
The JavaScript library is highly experimental and is proprietary for now. We may polish and release it as open-source at some point, but at present it’s far too specialized to be generally useful.














Para quem tem acesso a uma cortadora por Jacto de Àgua, e a um Torno, podem construír esta pequena Maravilha, e terem assim a vossa própria Prensa Manual:





Hand+Ink Letterpress in Aluminum
kniegmann 
I recently had some time to revisit my mini letterpress project. After using the earlier design for awhile, I wanted to redesign the press to eliminate all 3D printed parts and make it out of metal for increased strength. This press can be made out of MDF or Aluminum with a few quick dimension changes. The files attached are for 5mm thick aluminium sheet. Almost of of the parts can be cut with a laser cutter/waterjet/cnc, although I did use a lathe to make the wood handles and the top cross bar. All dimensions are in mm since I have recently moved to Sweden.
