Codeable Objects, Scanner 3D com Arduino, Pantógrafos e Tractores

Dica de Paulo Costa, através dos nossos amigos da DIGI-FAB USP, eis Codeable Objects, de Jennifer Jacobs, para fazerem Atrefactos usando Computação Geométrica, para adicionarem estructuras à vossa Impressão 3D:


Codeable Objects

Codeable Objects is a library for Processing that enables novice coders, designers and artists to rapidly design, customize and construct artifacts using geometric computation and digital fabrication. The programming methods provided by the library allow the user to program a variety of structures and designs with simple code and geometry. When the user compiles their code, the software outputs tool paths based on their specifications, which can be used in conjunction with digital fabrication tools to build their object.
The first case study for the Codeable Objects library was conducted with a set of methods that facilitated the creation of a laser cut lamp. To test the library, I held a workshop at the MIT Media Lab. Over the course of a day, participants used the library to design, and construct lamps of their own.  All of the lamps displayed in the images were created by people in the workshop.



Um Instructable para Fabbers, Engenhocas, e fâs do Arduino, eis uma Scanner 3D, feita usando Lego Technik, um Stepper, e o tal Arduino:

Ever wonder of copypaste method, usable in real life, not only in virtual reality? Me too. It is  21th century, and those are nearer than most of all can imagine! This is possible thank to 3d scanners and printers. So let's try to scan something!


 

Eis, apresentado pelo Blog da Shapeways, uma ideia que eu também tive, e falei dela aqui, algumas vezes, usar um pantógrafo 3D, para reproduzin N vezes um Original feito dum Obecto Impresso em  3D...
E numa Figurina absolutamente... Re-vigorante!

3D Printing Reinvigorating Wood Sculpture

We get to see a lot of amazing uses for 3D printing here at Shapeways, but this technique is new to me! Ben Godi from Italian company 3D Wood shares a really interesting technique that combines 3D printing and traditional wood turning.

In his words...

Hi I'm Ben and I would like to share a production process I have developed this year, together with a local wood carving company 3D Wood. We already use this production pipeline daily now, because it has so many advantages and Shapeways plays a major role! (how could it be otherwise!) I'm going to explain the steps with the help of two models that are for sale on my website.

Muáháháháhá! O sistema contraptor oferece-nos esta pequena gema de Vídeo, para além, é claro, de toda uma discussão e dados sobre um Mini CNC feito com as suas peças... É muito bom!


 
 
Mini CNC case study
Albanetc

This is what I made tonight. This is just a wheel. I wanted to test how it would come out before cutting the inertial damper wheels for steppers. It took about 10 minutes to cut, using tungsten carbide bit, speed setting 2, pass depth of 0.02" and feedrate of 12 IPM. I got these parameters from earlier mini router experiments/tests.



E como está o que os Especialistas chamam de... Frio comó caraças, aprendam como instalar uma Sopradora de Neve, nos vossos Tractores, nest caso o popular Tractor Kubota!

Installing snowblower on Kubota BX tractor
nlinventor

Fist snow of the year  this morning and more is forecast for tomorrow so I got the snowblower on just in time. This rear mounted Kubota snowblower does a good job clearing snow but getting it installed is always a bit of a challenge, especially as it's something done just once a year so you don't get much opportunity to develop smooth installation techniques.

I stored the snowblower and 3-point hitch parts under a tarp all summer, but even with that, a lot of oil and grease evaporated and some rust set in.  I live in a damp climate so that doesn't help any.

The photo above shows the snowblower fully installed, adjusted and lubricated. 



E para que os Canitos não vos arranhem a porta toda, eis uma ideia simples e eficaz, para poupar a Porta:


Sliding Dog Gate Protects Door from Scratches

Anyone with a dog knows that if you let them out to do their business you better be waiting by the door when they want to come back in. If you're not, it's a sure bet that they will be scratching at the door trying to get your attention and, the bigger the dog, the greater the damage. This instructable is a classic example of my "closing the barn door after the horse got out" but, hopefully, it will save your door before it meets the same fate as mine.

Um Brasileiro Fundador do Facebook, uma Arma excêntrica, uma Bateria de Condensadores, e o Contraptor

Eis Eduardo Saverin, Brasileiro, e um dos Fundadores do Facebook!
Ora toma!



Eduardo Saverin From Wikipedia, the free encyclopedia
Eduardo Saverin Born March 13, 1982 (age 30) São Paulo, Brazil Residence Singapore Nationality Brazilian[1] Alma mater Harvard University (B.S., Economics, 2006) Known for Co-founder of Facebook Net worth steady US $2 billion (March 2012)[2] Eduardo Luiz Saverin[3][4] (born March 13, 1982;[5] Portuguese: [eduˈaɾdu ˈsaveɾĩ] or [saveˈɾĩˑ]) is a Brazilian internet entrepreneur and investor.[6] Saverin is one of four co-founders of Facebook, along with Mark Zuckerberg, Dustin Moskovitz, and Chris Hughes.[7] As of 2012, he owns less than 5% of Facebook's shares and has a net worth of $2 billion, according to Forbes. He has also invested in early-stage startups such as Qwiki[8] and Jumio.[9]

Um revólver excêntrico, três canos e 16 tiros, com a possiblidade de disparar os 3 canos por tiro!



The triple barrel, 18-shot Pistola con Caricato revolver

By Brian Dodson

A host of unusual firearms have been floated and (mostly) abandoned over the two centuries of largely trial-and-error design. After our recent coverage of Arsenal Firearm's AF2011-a1 double barrel semiautomatic pistol, we wondered if more extreme versions of multi-barrel repeating handguns existed. The outlandish Pistola con Caricato three-barreled revolver is a definite candidate.
This revolver was manufactured in Italy during the early part of the 20th century, complete with three barrels and 18 chambers in 6.35 x 16 mm semi-rimmed caliber (.25 ACP). While rather more bulky than one would want in a pocket handgun, 18 shots would provide a certain feeling of security in back alleys and dark lanes.

Para chamar a atenção de Alunos e quem mais queiram, uma Bateria de Condensadores, a partir de Cãmaras Fotográficas de deitar fora:


Make a cheap disposable camera capacitor bank



This instructable will show you have to make a simple capacitor bank and charger out of old disposable cameras that you can get for free at your local store.

You can then use it for powering things such as coil guns or just blowing things up! See the second picture above? that was the spark created when I discharged such a capacitor bank. It was also very loud too!






O Contraptor vem-vos dar a possibilidade de criarem os vossos projectos, como um Meccano para CNC:



What is Contraptor

Contraptor is a DIY open source construction set for experimental personal fabrication, desktop manufacturing, prototyping and bootstrapping. 

Make Contraptor
You can make components of the Structural + Basic linear motion subsets of Contraptor at home for about $300 in parts and materials, plus shipping, taxes and time. Sketchup models of Contraptor components are hosted on Google 3D Warehouse while the DXF exports and SVG templates are hosted on Thingiverse.
Help beta test Contraptor - order one of the beta kits. The kits are currently made to order.
