Micro 105 FPV Quadcopter - 3D Printed punkkills 
I've been flying 250 sized FPV (first person video) quadcopters for just over a year now. For those who aren't familiar with FPV, you outfit a camera to the front of your quadcopter and transmit the video to a pair or goggles or a monitor. You then get to pilot the quadcopter from the perspective of the aircraft. It is so much fun and lets you fly in ways that would be impossible line of site.
I wanted to build a micro FPV quadcopter that I could fly around my house and in areas where my larger copters are too big. I have a 3D printer so I was hoping that I could find a 3D printed frame that I could use. Unfortunately, I couldn't find any 3D printed frames that were exactly what I wanted. I decided to design my own! My goals were to keep it crash resistant, light weight and offer good protection for onboard gear.
I'm going to walk you through the steps to building your very own micro FPV quadcopter. You will have a blast flying it and will have the pride of having built it yourself!

Este nosso amigo, Shiv Kumar Ganesh‎, mandou um Link para a Internet of Things, IoT Internet of things technologies, e é algo de imprtante que importa partilhar... 
SAM, é uma maneira de desenharem e prototiparem a brincar! 

SAM – The ultimate Electronic toolkit for your IoT applications
May be you are a developer or rather you are a designer but SAM brings joy to your life. Using it you can start developing without coding. SAM is a one stop solution to get started with IoT Solutions. SAM brings you an awesome way to learn about Internet of Things, Coding and seamless integration of Hardware and software.

So one can conclude by seeing these videos as well as the content that SAM is the best one stop solution for kids as well as engineers. This can be revolutionary when it comes to education as well as the way people understand the various aspect of connected life.

Esta Dica vem-nos de Henry Owen, na Promo Video Buzz, podem fazer os vossos Video-Blogs no Youtube, ou até Produções Teatrais, etc. com um ar bem mais  apelativo, com um Écran Verde, e um fundo à maneira...
Pois aqui, vão aprender como fazê-lo em casa!

E partirem daí, para o que quizerem fazer!

10 Breadboard Projects For Beginners

Breadboard is a great way to construct electronic projects easily and in less time without the need of soldering. A problem that is faced by beginners in the field of electronics is that they cannot solder the components neatly on printed circuit boards. One bad solder joint can lead to the project not working. When the project does not work, they eventually loose their confidence and cease to continue making projects. Before attempting another project, they have to think twice. Another problem faced by them is that if they try to solder and make a project, it does not work because of poor soldering or the circuit that was taken from a book or magazine lacked instructions or it was wrong. Now after spending a lot of time on making it, what they have to face is dissapointment.
This instructable gives a walkthrough of ten projects that can be made easily on a standard size breadboard thus solving the problem of hobbyists. Each projects is followed by a schematic, a breadboard layout, complete description with instructions, parts list and the difficulty level. The difficulty level increases as you make each project. Before making the projects a description of breadboard as well as electronic components is given which gives a complete understanding to beginners. All the projects are tested before they were added and all of them work. 

..E isto a seguir, dá-nos esperança na Humanidade!
À espera que este jovem Génio ou patenteie esta maravilhosa Invenção, ou a torne Open Source, admirem o que é o nascimento duma Ideia que vai marcar o Mundo das Marionetas, para sempre!

NEW PUPPET CONCEPT (24/05/16)barnabydixon
Here's a new puppet concept that I designed and built during the last two months. It took some time to refine, and alterations may still be made, but it's at a stage now that I'm happy to show y'all.

Brixo, Lego e electrónica! E Tinta que muda de côr(!), Câmara de Infracvermelhos, Massa sem Borax, e a máquina de aproveitar garrafas.

Para facilitar ainda mais a vida aos Engenhocas, aparece agora Brixo, que faz da electrónica um sinples Jogo de Montar!
Com Motores, Sensores, e Bluetooth, e compatível com o Lego, esta nova ideia ajuda-vos a ter ideias, e a pô-las em prática.

What is Brixo? 
BRIXO's electric bricks are normal sized building blocks that are anything but normal. It's like Lego® on steroids, if steroids also gave you superpowers and taught you new languages. 
Basically, they're bricks that safely conduct electricity and connect to your phone to enable you to do all sorts of cool things with your designs.  And no, you don't need to buy a whole new set, because they're used interchangeably with your favourite building blocks to add an element of interactive awesomeness. 
BRIXO bricks include LED lights, motor blocks and even sound, light and proximity sensors. They’re powered by a low voltage Bluetooth controlled built-in battery brick and coated in chrome, a non-toxic metal, to ensure your safety. 

Um Projecto bem Didáctico e divertido, eis como podem aprender a...
Fazer a vossa própria Tinta que muda de cr!
Neste caso, a Tinta muda de côr conforme a Temperatura!
A gama de usos possíveis é infinita. 

How to Make Colour Changing Paint
In this tutorial I am going to teach you how to make a colour changing paint. On this occasion, I have chosen to create a paint that changes colour with temperature (thermochromic).
There are so many applications in which thermochromic coatings can be used. Some of these include, colour changing t-shirts, colour changing posters, colour changing birthday cards, promotional items and educational products. 

Não faltam Telemóveis, ou Celulares, por casa, com Câmara, mas sem mais uso, nestes dias, então, porque não, transformá-los em Câmaras de Infravermelhos?
É escandalosamente SIMPLES, e é o que vão aprender, neste Instructable: 

Make Basic Infrared Thermal Imaging Camera For Cheap ! Convert Any Camera Into Infrared Thermal Camera
Kedar Nimbalkar
How To Convert Any Camera Into Infrared Thermal Camera Very Cheap But Useful Hack . Every Camera Sensor Has Ability To See Infrared i.e. Thermal Part of The Light But The Infrared Blocking Filter Inside Digital Camera's Protects The CCD Sensor From Burning With High Energy Infrared Light Such as Sunlight .
Now , If We Remove The Blocking Infrared Filter The Camera Can Also Able To See Infrared Part of The Spectrum of Light ! Which Is Pretty Cool Because After This Hack You Can See Hot Objects With Your Camera Glowing More As They Emit More Infrared Energy & Many Other Things You Can Do Like See Through Some Clothes , Black Objects Which Takes Teardown To a Next Level !  

Mais Diversão, para Engenhocas novos e velhos,  eis como fazer Flubber, em casa, mas sem utilizar Bórax, que não há à disposição em todos os Países:

No Borax Or Starch Flubber/slime/putty
I've been looking for a no starch or borax flubber for a long time
Some recipes had tide, cornstarch, lotion, clear glue and other ridiculous ingredients
Today, I found a recipe on YouTube on flubber and sounded very believable
I tried it out and a total fail
I then viewed the videos comments and one said just use glue, eye drops and baking soda
I tried it out with using the same ingredients in the video and the same ingredients the comment suggested it turned out great
But it smelled horribly like bleach and it was very wet
It was also very airy and not that stretchy 
So I just used the recipe the comment suggested 

E vamos dar as Boas-Vindas a este nosso amigo Romanurshuak, que conheci através dos seus Vídeos no Youtube, e em boa hora lhe sugeri que fizesse também Instructables, pois cá está este, para aproveitarem Garrafas de Plástico, com esta magnífica Engenhoca que as desfia, em rolos que podem aproveitar para vários fins:

How to Make a Plastic Bottle Cutter / Tutorial
How to make a rope out of a plastic bottle?
We often need a strong wire or rope at rest or at the cottage. For example, you need a linen rope, and there's nothing suitable at hands. Don't worry! It is possible to make a long and strong rope out of an empty plastic bottle.

How to Extract a Cell Phone Motor's Flywheel

There's an endless source of Micro-motors, in old, discarded Cell Phones.
Trouble is, they come with those pesky, off-balanced Flywheels, that mess up everything, as no one wants wobbly motors that can't be connected to the gearwheels, pulleys, and what not, you want to use these motors with.

Yes, and Quadracopter's Propellers, too! :)

Flight-case Toolbox and Workstation


My toolbox is an expression of my making practice. It has developed over the past 5 years as my needs and abilities have changed as a fabricator and artist. Some of the tools are specific to the kind of work I generally do, which is usually a blend of mechanical and electronic. It includes LEDs, a electrical system with a power tool charger, benchtop power supply, and soldering iron. It has a mirror and an anvil. It is heavy and I love it. I hope you do too.

3D multifunções? E uma versão DIY, apanhar fruta, pregar pregos, Jacto de Areia, e Simulação de Circuitos!

Se há Impressoras Multifunções, porque abóbora é que ninguém aparece com uma Máquina CNC, do mesmo modo, capaz de Corte Laser, Impressão, Fresa CNC, etc?
Pois já há! 
A Construindoo brilha outra vez, com este achado, uma Máquina CNC Multifunções, dersenhada e feita inicialmente na Alemanha, um espectáculo de Design e Qualidade Germânica!

CNC de Mesa Multifuncional - All-in-one Desktop CNC

A Stepcraft 2 está disponível em 5 tamanhos para melhor atender às suas necessidades: 210, 300, 420, 600 e 840 milímetros de comprimento de espaço de trabalho útil.  

Eis senão quando, aparece, logo a seguir, este Instructable, e funciona com um Raspberry Pi, por isso, sai bem baratinho!

Raspberry Pi CNC Machine
My friend and I thought about building a CNC Machine for a while. But we didn't want it to be just an ordinary CNC Machine. We wanted to make a very unique machine that could have very unique attributes. We set out to make a CNC Machine that could do different types of Machining. For example, routing, laser engraving, 3D printing, drag knife, etc. We took about a few months to design the basics of the machine. For example, what kind of linear motion we would have for each axis, what kind of material we would use for it, what kind of style to make it, etc. We chose our build area to be 24" X 24" X 7". After those few months of finalizing everything, we took our first step into physically making the machine. Note: This is made for the average consumer, for home use, and for someone who doesn't have the money to invest in a $1000 CNC router or 3D printer. 

Agora, 2 das tais "ideias óbvias", mas alguém teve de as ter, primeiro...

Uma maneira de quem tem quintal, apanhar fruta, sem Escadotes, nem chatices!
Um simples Tubo de PVC, e muita cabecinha, e voilá! 
Apanham a Fruta toda. 
E vem com mais 2 ideias práticas, de Bónus: 



This berry picker is made out of PVC pipe. Heat is used to shape the plastic. Two "fingers" at the working end do the picking. The berry then falls through the pipe and lands in a plastic bag tied to the other end.
This berry patch belongs to a neighbor. I plan to grow some at my house on rebar trellises, for easier maintenance and harvesting. See my trellis instructable when you are done with this one:
Also, for further PVC working inspiration, see my instructable: 

A segunda ideia genial, a ideia não é minha, para pregar pregos sem trilhar os dedos.
Mas o Instructable, para fazer isto em casa, em 5 Minutos, e com só um tubo e um ìmane, é mesmo da minha autoria:

5 Minute Thumbsaver

As seen on Youtube, here's the Thumbsaver!
Only, a more modest version... Cheaper, too!
This is another no-brainer, that will save you a lot of grief, a nail setter, for nails, of course, 

and other fasteners.
It's just a question of finding some tube, and then in 4 or 5 Steps:
-And cut, (if needed) 

Ainda às voltas com a Oficina, uma Máquina de  Jacto de Areia serve para um sem-fim de usos, na casa, e para fazer ou manter peças de Engenhocas de toda a espécie, por isso, cá vai como fazer essa màquina em casa...
E atenção, se são amigos do Ambiente, (ou Sovinas, como eu), este desenho re-utiliza a Areia:

DIY Sandblaster
Make it Extreme  
Here we are with another brand new structure by the ‘make it extreme’ team, a Sandblaster.
This structure is capable for multiple uses such as removing the rust from old objects and coatings as well as writing on many different kinds of materials like glass, stone and others.
Our own design of the particular structure aims to recycle the sand in order to be able to use it more than once.

E para acabar em beleza, os nossos amigos da Página do Facebook Engenharia Elétrica e Eletrônica, vêem-nos dar esta dica bem bacana, que figura em Artilharia

Aprender sobre trilhos! E o Arduino sem Mestre, nem Solda, façam o vosso Filamento, uma Impressora para fazerem com Impressoras, e Kerf!

Brinquedos Didácticos assim, é outra coisa...
Uma aceleração brutal, nestes Modelos  de Monorail, e é certo que se mantém a atenção da Pequenada, na componente de Ensino do projecto. 
Apesar de ser um pouco caro, para indivíduos, não o será tanto, para Associações e Escolas.
E há sempre a possibilidade dalgum Engenhocas fazer isto, com Sucata e pouco mais! 

High Speed Rail Racer
De veloped in association with Stephen Hill, Head of D&T at Turnford School in Hertfordshire.
This amazing system has been designed to put the WOW into a range of STEM activities. Using a simple friction drive principle, small electric vehicles running on an electrified rail can achieve astonishing acceleration and speed from a standing start. The rail concept has parallels with both large-scale linear rail transport systems and small-scale goods transfer lines used in manufacturing - and offers pupils or students unlimited opportunities to learn through a highly motivating and enjoyable technical challenge.

E para aprenderem a dominar o Arduino, nada melhor que este Kit, que vos ensina a criar as vossas Engenhocas, sem sequer se meterem a soldar componentes, nem mesmo, precisam um Breadboard!
Mais fácil, não há! 

The Arduino Coding Kit is an intro to programming, allowing anyone to create and code inventions without breadboarding, soldering, or wiring. Learn the basics of coding as you create and program 8 inventions, or upload code from the site using codebender.  

Se acham que o Filamento para as Impressoras 3D está muito caro, já podem é recorrer à vossa própria Fábrica de Filamento, e fabricar o que precisam, e fazendo essa Fábrica caseira com pouco dinherio:

Build your own 3d printer filament factory (Filament Extruder

Too long, didn't read:
Make your own 3D printer filament !
Cheap and high quality at a decent speed of 150-190 IPM ! (4-5 meters per minute)
UPDATE: Now with wiring diagram !

Long read:
3D printers are cool and they finally start to drop in price. Kickstarter campaigns like the one from QB-UP or M3D are popping up and they are finally "affordable". And with affordable I mean affordable like 200 $ and not "affordable" like 2.199$ affordable. However, once you are a proud owner of a 3D printer you will soon realize that your wallet is far from being let alone. No ! You need plastic filament of course to print those super awesome coat hooks and wheel chocks. Since the price for these filaments tend to top the actual material costs, printing before mentioned life savers is kind of expensive and could become a problem to the development of the ever growing 3D printer community
BUT FEAR NO MORE !! Some clever gents came along - Hugh Lyman with his Lyman Extruder may be mentioned here or the guys over at - and saved the day ! YAY. And there was much rejoicing ! They have built plastic extruders everyone can build or buy at a decent price. However if you are a fellow user the first thing that should come to your mind is "I can build this by myself...and cheaper...". Building at lower costs is the nature of DIY after all.
And much more fun than putting together a premade kit, of course.

Para continuar neste tema, se já têem uma Impressora 3D, mas precisam de outra, pois podem fazer mais uma, com peças que fizerem na primeira.
E com duas, pode acabar com 4, etc...

The D-Bot, my self made reprap.

After I bought my first printer and began printing for friends, I felt I could use a 2nd printer. Instead of just buying a 2nd one, I came up with the idea to build a reprap. I had a printer, so I could print the parts. You could buy the other parts everywhere on the internet, so that wasn't a problem either. I began creating a design that was easy to built, compact, cheap and still accurate. Continue reading to see if I succeeded!

Já aqui falei antes de Kerfing, a técnica que nos permite obter Madeira curva, sem Câmaras de Vapor, pois tal pode também ser feito sem Laser CNC, mas com este acessório, nas vossas Serras eléctricas:

An Easier Kerfmaker

Phil B
Someone showed a group of us a simple kerfmaker he built from scrap. I was reminded of a nice aluminum kerfmaker Instructable posted by Steliart and I thought about building it. This Instructable describes an easier kerfmaker I built from some hardwood. It is not a disposable kerfmaker fitted for only one tool. The precision sliding parts are so easy to make well that it is almost foolproof.
A kerfmaker is initially set by you for the thickness of your cutting tool (saw blade, router bit, bandsaw blade). From that point, it allows you to set the kerfmaker for the thickness of a piece of work so you can make a precise dado for that piece without further measuring.
