How to Augmented Reality Tutorial: Virtual Buttonsmatthewh8 

This tutorial is geared towards beginners so you won't need any prior experience with AR, Unity, or Vuforia. The video above goes through everything step by step. Overall, the video shows you how to implement virtual buttons with the augmented reality Vuforia SDK in Unity. This tutorial shows you how to create a zombie scene on top of a fiducial marker and then play a walking animation when your hand goes over the virtual button. Upon trying to figure out how to use these virtual buttons I quickly found that there is not much information online. I hope this video helps some people!
All you need to follow along is a computer with a webcam.
As far as software you will need Unity https://store.unity.com/?_ga=1.97655965.303547796.1455211926and the Vuforia SDK: https://developer.vuforia.com/downloads/sdkThanks for watching!

Cortesia da Autodesk Circuits, vocês nunca mais se vão fartar do Arduino, não, com estes mais de 100 Projectos, desde Óculos de LEDs, até como fazerem o próprio Arduino, numa placa Breadboard!

E também vem com um link bacano, desta vez, para o Electronic Lab...

100+ Arduino Projects

Autodesk Circuits 

Whether you are just beginning or have extensive experience with Arduino, there is something here for everyone.

In the Electronics Lab, you can prototype and design before you build a circuit in real life. The lab also allows you to program and simulate any Arduino code in the editor.

If you've made something cool using Arduino, share it. We'd love to see it! All you have to do is post a link to your circuits design or Instructable on social media (Twitter, FB, Instagram) and mention us @adskcircuits.

Isto é que é qualidade!

Já antes mencionei, e analizei, com Dicas, a Neje, que é uma máquina capaz de vos iniciar nas maravilhas da CNC, mas isto...

É outra coisa!

Maior, mais robusto, modular, vale bem o preço mais elevado:

MINI XY LASER ENGRAVER 

How do you usually represent your ideas, through drawing, taking photos or engraving it on your favorite objects? This Mini XY Laser Engraver, a perfect combination of Makeblock metal beams, stepper motors, a MegaPi and an engraving laser head, allows you to engrave everything you want. Compared with XY Plotter (with Laser Engraver Upgrade Pack), Mini XY Laser Engraver is much more portable but of the same capabilities.

Uma grande dica, mais uma, dos nossos amigos da apometron downloads, uma carrada de Software Portátil, que se pode pôr numa Pendisk, e andar por todo o lado com Programas que são capazes de seintalar emqualquer PC!

E isto, num Download Grátis...

Muito bom!

winPenPack: Portable Software Collection 

winPenPack is a project that aims at collecting the most frequently used and most popular open source applications made portable, so that they can be executed without installation from any USB Flash Drive or Hard Disk. The winPenPack suites offer a wide range of portable applications like office tools, internet tools, multimedia tools, development tools, security applications and other frequently used utilities. Everything you need, completely free, open source and portable!

Eu adoro electrónica, mas odeio soldar!

Eu, e a minha Rinite Alérgica, e saber que "fumar" Chumbo, dá cabo da Saúde a qualquer um...

Por isso, um ganda "Bravo!" para este Projecto, que não só vos tira o fumo debaixo do nariz, com, com Carvão Activado, não espalha esse fumo pelas vossas salas!

Impecável! 

Solder Fume Extractor With Activated Carbon Filter

nqtronix 

For years I've endured soldering without any ventilation. This is not healthy, but I got used to it and didn't care enough to change this. Well, until I got the chance to work in a lab of my university a few weeks ago...

Once you've experienced the huge benefit of a solder fume extractor you never, ever want to solder without one again.

I didn't wanted to invest much money or time, though. This design is simple yet pretty, can be build within an hour and is student-budget friendly. But most importantly: The air is not just pushed around, but cleaned through an activated-carbon filter. It has a "suction range" of about 20cm and can handle even gross amounts of fumes from additional flux.

Dia de Instructables Impecáveis

O meu trabalho está facilitado, hoje, Instructables tão indispensáveis, para tanta gente, que, para bom Engenhocas, meia palavra basta!

Sem mais cá vão eles, que é uma limpeza...

Primeiro, não gastem mais que 30 Dólares para fazerem este bacano Scanner 3D, e começarem a digitalizar tudo o que sejam Objectos à mão.
Para que não vos falte nada, até o Software, o Sardauscan, é incluído!

Build a 30$ laser Scanner

Sardau

Introduction

This instructable will guide you to build a 3D scanner for less than $30, or even $12 if you already have a USB webcam.

Seeing the price tag and limitations of commercial scanners I decided to challenge myself to build my own. It had to be cheaper and easy for anybody to build one using a 3D printer.

Result

The "Sardauscan" is a laser scanner, comparable to other professional laser scanners but for less than 20-30 times the price, and it has twice the number of lasers.

My design principles were:

· Keep it simple

· Keep it low cost

· Make it evolutive

· Provide a complete solution

The scanner is completely open source and open hardware:

· The "Sardauscan" software is written in C# - the full source code is available.

· You can write plugins for your own hardware or for your tasks.

The software allows you to scan, smooth, build meshes and export to various formats.

I bought a small harbor freight lathe for 200 something and never had the money to buy all the tools I wanted for it. so I started creating them as I went. hope you are inspired.

Mini Arduino CNC

me_zain

This instructable shows you how to build a cheap and easy, but very small CNC using Arduino UNO. You can use it to mill thin wood, different foams or you can use it for plotting different sketches and also can be used for engraving and etching purposes.Inspired by the Small Arduino CNC (thank you very much for your help), i made it easily.
PARTS YOU NEED:
For this project you will need:
3 old CD/DVD-Roms
1 Computer power supply
3 Easydriver boards
1 Arduino Uno
2 pieces of Wood

http://www.instructables.com/id/Mini-Arduino-CNC/

...E para rematar, cá vai esta Máquina CNC que faz de tudo, Impressão 3D, Fresa 3D, e corte  Laser, numa só caixa!

É bom?
É nada menos que ter tudo para se ser um Fabber, num só canto da Oficina!

Triple Threat: BoXZY Puts Printing, Milling, and Lasers in One Small Box 

Matt Schultz

On my way to the Midwest RepRap Fest, I stopped in at HackPittsburgh to meet up with the BoXZY team and take a look at their new machine in person. BoXZY is doing well on Kickstarter; with its promise of being an all in one 3D printer, milling machine, and laser etcher, it’s enticing backers. The BoXZY features a thick aluminum case that creates a stiff structure to help support its milling function. All movements are achieved with precision ball screws instead of the belts often found in 3D printers. I expressed my concern about the exposed screws getting “gummed up” from the milling operation, but the team ensured me that through their testing they have not seen any contamination in their bearings from milled material, and that they are working on a system to help ensure this.
