Functional 3D Printing Looking Attractive with New Magnetic Filament from Graphene 3D Labs
MICHAEL MOLITCH-HOU 
Graphene 3D Lab Inc. has already demonstrated some success with the release of their Conductive Graphene Filament, which at least one of our team members thought was fun to play around with. Now, the Canadian company is introducing yet another functional filament and, this time, it’s sure to attract some attention. Currently for sale on the company’s online store, BlackMagic3D, and on Amazon is Graphene 3D Lab’s all new Ferro-Magnetic PLA filament. 
As must as one might like to create fridge magnets with the material, the new magnetic filament from Graphene 3D Lab can actually be used to make functional objects like sensors, mechanical actuators, and motors.  I won’t pretend to know how to build these, but there are plenty of tutorials online describing how to make magnetic motors, sensors, actuators, and more.  Combined with conductive filament, we are slowly approaching the day in which all the parts necessary to reproduce a 3D printer will be 3D printable, fulfilling the dreams of RepRap founder Adrian Bowyer.

Arduino Laser Engraver Wood Design!
MichielD99 
Hi everybody, my name is Michiel and I am going to show you how to make an awesome looking laser engraver!
A couple of months ago, there was a CNC challenge here at instructables, while checking out the entries of that contest, I saw some pretty cool engraving machines and I thought: "Why shouldn't I make my own?". And so I did, but I didn't want to make someone else's project, I wanted to make my own. And so my story began... :)
This laser engraver uses a 1.8W 445nm laser module, of course, this is nothing compared to the industrial laser cutters who use lasers of (a lot) more than 50W. But this laser will do well for us. It can cut through paper and cardboard and it can engrave all kinds of wood. I haven't tested other materials yet, but I'm sure it can engrave many other materials. l will let you know! It has a large engraving surface of about 500x380mm.
Who can make this laser engraver? Everybody, if you are an engineer, a lawyer, a teacher or a student like me, you can build this thing! All you have to do is follow this instructable. 








Para Modelos e Maquetes bem realistas, mas numa máquina acessível, esta nova Máquina da Mcor vem-vos ajudar, agora ainda mais, porque vem com uma data de truques novos!



This 3D Printer Builds Full-Color Paper Models!

Tested


Traditional desktop 3D printers use melted plastic as their build material, but Mcor's printers layer sheets of paper on top of each other to create their models. We check out the new Mcor Arke, a printer that cuts from a large spool of paper, glues those sheets together, and then prints color on them to turn digital files into large paper models!

235 Dólares, e feito em 7 horas, não há razão para não tentarem!




How to assemble very cheap 3D printer
Nikus 
3D printing is great tool, you can print almost everything that you need. For example my lamp was broken since few weeks but now I design part that I needed to fix it and it works!
Cheap printer maybe mean for somebody bad printer. But I think that for this price ($235)it works great. It can print offline, has heated bed (without glass table but I will show you how to make it). Assembling it is very easy. I made it without instruction (I didn't check SD card, on it you can find some video tutorials). It took me 7 hours to build, calibrate and print first thing (small 1cmx1cmx1cm cube). 









..Mais esta, como, com a vossa humilde Serra Tico-tico de Bancada, podem fazer Engrenagens Cónicas, as tais a 90º!
Para quem queira fazer maquinetas em Madeira, isto é indispensável... 
E até vem com os Planos para o Helicóptero que aqui vêem!
É bom!

Não se é Engenhocas, sem se acabar por acumular uma série de Motores Eléctricos, e eis que vem este noisso amigo, Taifur, ajudar-nos a encontrar o que fazer com eles, no campo da Robótica, e não só:




Complete Motor guide for Robotics

taifur 
Robot is an electromechanical device which is capable of reacting in some way to its environment, and take autonomous decisions or actions in order to achieve a specific task.
Roboticists develop man-made mechanical devices that can move by themselves, whose motion must be modelled, planned, sensed, actuated and controlled, and whose motion behavior can be influenced by “programming”.
This definition implies that a device can only be called a “robot” if it contains a movable mechanism, influenced by sensing, planning, actuation and control components. Motors and actuators are the devices which make the robot movable. Motors and actuators convert electrical energy into physical motion. The vast majority of actuators produce either rotational or linear motion.
In this instructables I will explain more common types of motors and actuators, their basics and how to control them. 










Sugerido por mim, a eles, e em boa hora, eis que a KJMagnetics nos oferece mais um simpático Instructable, sobre como construír em minutos este carrito, que é tanto Didáctico, quanto divertido!



Magnet Car

KJMagnetics 
Here is a quick, easy way to create a self-propelled car using simple household items! All it takes is some magnets, a AA battery, and some aluminum foil!

Façam o vosso próprio Micro-PC! E Motores a partir das Impressoras, um cartão de Visitas Digital, e uma Base para Fresa Dremmel.

Com muito pouco, fazem o vosso próprio Micro PC, daqueles que carregam directamente dum Chip, usando este Instructable:


Make your own 'Home Computer'

gfwilliams
Many of us learnt to program on a Sinclair Spectrum, Commodore 64, BBC Micro or similar - 8/16 bit Home Computers. These computers booted straight up to a command prompt and encouraged you to write code and play with them.
You can now make your own (that runs JavaScript) in a few hours using a Espruino Pico microcontroller!







E que tal fazerem um Quadracóptero a partir das vossas Impressoras? Ora aqui está uma ideia mesmo bacana...




Upcycle Brushless DC Motors From Printers

ossum

If you are at all interested in robotics and electronics you will probably have disassembled an old printer or two (if you haven't, I highly recommend it, there are always interesting parts, and you can learn a lot about how the experts put electro-mechanical machines together). If you have taken a laser printer apart, you will likely have come across brushless DC motors, which range in size.
These motors have some pros and cons, obviously it varies between printers, and the functions of the motors within the printers, but I have found the following to be true most of the time 
http://www.instructables.com/id/Upcycle-Brushless-DC-Motors-From-Printers/ 










Aqui, explica-se como vocẽs podem ter o vosso próprio Cartão de Visitas Digital...
Pois não é que esta gigajoga transfere o vosso Contacto, para o Smartphone de quem vocês conhecem?
Simplesmente... Fantástico! 





Digital Business Card with NFC
Joep1986 
NFC is found everywhere these days from credit cards to door locks, but must importantly: your smartphone! With a few simple steps and relatively low costs you can create a digital business card that uses NFC and can be read by a smartphone to transfer contact information. This high-tech solution makes exchanging your contact information not only fast and easy, but also makes you look very cool!
(this Instructable was made for the TfcD course @ TU Delft)

E se têem uma Dremmel, ou uma Maxcraft, etc. podem agora fazer um brilharete, com trabalho de Fresa, o que é sempre mais uma funcionalidade para estas pequenas maravilhas...

Notem o genial uso duma Pré-ferramenta em Cartão, para fazer uma Ferramenta final, em Madeira!
Ahá! 
O Génio Inventivo, está vivo, ainda!!!
