Aulas de Design 3D, free Class! E publicar 3D paramétrico, uma Câmara de Infravermelhos de Bancada, um Torno feito por Impressão 3D(!), E UM MOTOR BRUSHLESS!

Aulas à borla, é bom!
Estes nossos amigões da Autodesk, oferecem-nos uma série de Aulas bacanas para aprenderem a desenhar 3D, no programa Fusion 360, como deve de ser.
Vão-se lá inscrever:

Autodesk Design Academy 
Learn 3D modeling in Fusion 360 in under an hour! Whether you are new to CAD or already using parametric CAD software, this short video-only class includes everything you need. We'll introduce you to valuable tools for learning and teaching Autodesk Fusion 360 essentials, and give you great tips and tricks from industry professionals. Through a scaffolded learning experience, you'll develop your 3D modeling skills by applying them to a real world design challenge inspired by the Louis Kalff "Krähenfuss" table lamp.
The class includes step-by-step video instruction, a printable PDF guide, and a quiz.
Let's get started! 

Desenho 3D paramétrico, é outra coisa.
Porque é infinitamente adaptável!
Só para dar o exemplo mais óbvio, um Desenho paramétrico dum par de sapatos pode ser configurado para todos os tamanhos, cada número de Calçado é uma derivação dum desenho-base.
Por isso, este novo serviço, Profissional, permite-vos publicar um Modelo, e esse pode ser configurado N vezes, para os vossos clientes, por todo o Mundo.

ShapeDiver is a web service for publishing parametric 3D data. It is run by ShapeDiver GmbH, a limited liability company registered in Vienna, Austria. Alexander Schiftner, Mathias Höbinger and Mathieu Huard founded it in 2015.
Our motivation is to bring parametric modelling to the web, and to make it a smooth, convenient and exciting experience for both designers and viewers. We want to offer the flexibility of mass customization to every company, big or small, in a simple web browser. Read more about our mission.
Our responsibility is to do it in a way that respects every designer's needs and concerns, be it regarding intellectual property rights, data security, privacy or any other issue that concerns you when you think about the idea of uploading your precious work to the cloud.

There is nothing like seeing your product through our technology for the first time. Request a demo and let us show you how parametric design can enable new possibilities for your company.

NewFLIR ETS320 Thermal Imaging Camera, Temperature Measurement Range: -4 → +482 °F 320 x 240pixel
FLIR ETS320 Test Bench Thermal Camera 
FLIR ETS320 is a professional, affordable solution designed for hands-free laboratory testing. Ideal for reducing test times and improving product design for electronic board and device evaluation. The ETS320 detects design flaws that materialise as heat. Which is an important indicator of how a system is functioning. The ETS320 helps engineers and test technicians collect accurate, reliable data in seconds and analyse it quickly.

Quando se é Engenhocas, é outra coisa...
Este bacano, como nas Aulas tinha de esperar à vez, para tornear os seus Objectos, vai mas é de fazer, ele mesmo, o seu próprio Torno!
Brutal! Bravo.

3D Printed Lathe
First off, I am a sophomore high school student who actively participates in FTC Robotics representing Shark Beta Team #10088 and FatherBoards Team #10087. The goal of our robotics team is to learn as much as possible before graduating and going off to college. One crucial skill everybody on our teams had the desire to learn was how to manually lathe parts our self instead of sending the files for somebody else to machine them for us. This was where the idea of building my own lathe came in. As our school did not want to purchase a full-size lathe or for that matter allow students to operate a full-size lathe; the only other option was to build a miniature one myself. The major challenge of this project was that because all of our funds go straight into our robotics program and purchasing parts, the lathe had to be constructed out of existing parts in our lab, or the parts needed to be made personally (this is where the idea of 3D printing the lathe itself came into play. Another major challenge of this project was that the lathe needed to be relatively precise and accurate so that the final parts could actually be used on our robots. Those were the main challences I was faced with and I believe I did a relatively good job at solving these. If you do decide to build this you will find how percise and accurite it is despite it being 3D printed. So lets get to building! 

600 Watts! 

Eis um Motor Brushless, que vocês podem construír em casa, se tiverem uma Impressora 3D à mão, ou puderem imprimir estas peças nalgum lado, nalguma FabLab...
Usa o Arrenjo Halbach, de que já falei algumas vezes, e é fácil de montar:

600 Watt, 3d-printed, Halbach Array, Brushless DC Electric Motor
This is a very powerful, 3d-printed brushless DC electric motor. It has 600 Watts, and performs with more than 80% efficiency. The main components like rotor and stator can be printed with a common FDM-printer. Magnets, copper wire, and ball-bearings are ordinary components. The magnets of the rotor are arranged as Halbach Array. The motor runs with a standard ESC widely used in different RC-applications (plane, drone, car).
