Electrónica Fácil! E Impressoras SLS mais baratas, Um E-Book da Sculpteo, e Coragem a sério!

Dica excelente do nosso amigo Alan Metcalfe, nesta Rubrica de E-Revista a seguir, Electronics Weekly, Engineer in Wonderland, surge esta maravilha, ou melhor, uma série de maravilhas, 10 Programas de Simulação de Circuitos Electrónicos, como Fontes de Alimentação, Apmlificadores, de monitorização, etc.
Tomem nota do Artigo, da Revista, e do Link para a série de programas que figura nele:

LED flasher 2: Hats off to Mr Kurt and LTspice

Mr Kurt, wise commenter of this parish, drew my attention to LTspice.
What a revelation :-)
LTspice is a free version of spice from Linear Technology, and it is delightfully easy to use, intuative, and seems to work rather well.
Note, there is a flasher version 3
Current through component and voltages on nodes can be displayed with a single click on the schematic.
Having messed for ages with my little flasher circuit on the bench, running it through LTspice has helped me think through its limitations and confirm some suspicions I had.
Good thing 1: It oscillated in spice – once I had messed with some values a little.
LED flasher block diagramThis is the basic idea of the circuit
My cunning idea (now proved to be not-so-cunning) was to have constant current supply to a capacitor and load it with an oscillator whose load is an LED.
The oscillator senses the capacitor and turns the led on when the supply voltage reaches a high threshold, then off when it drops below a lower threshold.
Providing the LED current is greater than the supply current, it should flash along happily and regulate the capacitor voltage.

As Impressoras SLS, as de pó sinterizado, estão cada vez mais baratas, dica da 3D Printers Online Store, o que as torna acessíveis a cada vez mais gente...
É bom!
Dica de Scarlett Jackson, vejam este Artigo sobre a Ester 3D Printer, a 2500 Dólares:

SLS 3D Printing Machines Are Getting Affordable

Even the expensive and most wanted SLS machine are getting affordable. Addictive manufacturing is getting more popular among scientist and engineers, who is not buying a 3d printer for research instead making a 3d printer with some unique features that no other current market does.

In no quick time we are hearing some good news about SLS machine which are hitting the market with bang, Ester 3d printer has launched their product in indiegogo at the rate $2500 which comes as unassembled. For those who doesn’t know about SLS machine cost won’t be surprised since the price usually around beyond $200,000, Brandon Fosdick is the genius behind this invention of Ester 3d printer and provides all these parts, hardware, software so that people can upgrade, modify this machine into a better one. This machine doesn’t support material as they accept the powder kind of material to get print.




Como saber que peças mandar imprimir, ou que Máquina comprar, quando se escolhe a Impressão 3D como parte da nossa Vida Profissional?
Eis um livro bastante completo, com os vários métodos de Fabrico, omparando-os e dando várias dicas sobre como mandar imprimir em cada caso.
Basta preencherem com o vosso nome e emal, que têem direito a este E-book, e ficam ainda a saber as novidades da Sculpteo.
De notar, o Link no fim da página, para o caso de quererem saber em quanto ficará mandarem fabricar uma peça repetidas vezes, para a Sclupteo: :

3D Printing / Traditional manufacturing: Guide to cost efficiency

In this guide, you will find a comparative study between 3D Printing and Plastic Injection Molding. In order to download it for free, all you need to do is fill the above fields.
In comparison with traditional production techniques, especially plastic molding, the advantages of 3D Printing go far beyond Rapid Prototyping or object customization.
Sculpteo’s online 3D Printing services allow professionals and consumers to produce short series in an economically competitive manner.
We conducted a study on cost efficiency through short series manufacturing with the hope to prove 3D printing’s competitive edge. The study’s goal: determine when it’s more cost effective to use 3D Printing (through SLS processes) as opposed to Plastic injection for your production.
Our study first takes into consideration qualitative aspects such as elasticity, resistance and finishes before switching to more quantitative research.

Isto é que é um caso de Coragem, de Família a sério, e de Serviço à Humanidade!!!
Estão todos aqui, de parabéns;
As Crianças, os Pais, e também, essa maravilhosa ideia que foi a KidMob.
Leia, e maravilhem-se com o melhor que a Humanidade produz, graças a Deus...

Playful Prosthetic Arm

I met nine-year-old Aidan Robinson at a summer camp he attended called Superhero Cyborgs. This camp, run by KIDmob, is a place where kids with a variety of limb differences design their own prosthetic and orthotic devices. Each kid's design was impressive, but Aidan's playful ideas really resonated with me. To me, Aidan's ideas were a model for how prosthetic devices could and should be more appropriate, useful, and fun than those typically used for both children and adults.The typical prosthetic arm has a robotic hand or a hook that does not adapt well to a variety uses.
Aidan was born without a left arm below the elbow and has had many different types of prosthetics, all leaving him feeling almost better off without them. Despite these hurdles, and like the resilient and creative kid he is, Aidan adapted extremely well to life with a limb difference and is more active than most kids his age. Because the prosthetic is a part of him, we both felt that he needed a device that accurately reflected his personality and interests.

Imprimir em Metal, um Jogo de Construcção, um Lançador de Aviões em Papel, e reciclem Plástico

Neste Kickstarter, dica de Dave Addinsal, na 3D Printers PT, uma Impressora 3D que cria peças em Metal, não só para Joalharias, mas peças sólidas e densas, por menos de 4000 Dólares!
A Equipe por detrás desta maravilha criava Motores de Foguetão, mas demorava muito tempo...
Por isso, vai de juntar esforços, e fazer uma Impressora que vai dar que falar.


At Last! A Metal 3D Printer for Under $4,000
Geoffrey Craig
There is a perception out there that the 3D Printing Industry is about plastic trinkets, being pumped out of Makerbot machines, but there is an ever-growing list of industrial applications for this technology. Metal 3D printers have had a surge in popularity in recent times, owing their ability to craft complex components for the medical, aerospace and automotive industries. Until now these metal 3D printers haven’t been cheap. With price tags upwards of $100,000, small businesses would have a hard time leasing them, let alone buying them.
Earlier this year, San Francisco based startup MatterFab introduced their version of a cost efficient metal 3D printer, which they hope to start building and shipping to partners earlier next year. Although the exact price of their metal 3D printer wasn’t revealed, they claim it would cost a fraction of the cost of previous metal 3D printers.

Este jogo de Construcção é especial, porque compram as peças, dum Estojo-Base, como tantos outros, mas podem aumentar o número de peças, na vossa Impressora 3D.
Para além disso, vem num tamanho que permite fazer coisas de jeito...
E ainda vem com uma app que permite à míudagem, e aos Pais que estão lá a ensinar brincar também, criar e visualizar Projectos antes de os construír, para testar a idéia!

3D Printed Paper Airplane Launching Gun

Cabe Atwell

What’s cooler than a paintball gun? How about a gun that fires the most lethal of all 21st Century weapons- paper airplanes. That’s right folks, feast your eyes on the paper airplane gun!

One tinkerer is very serious about his paper airplane game. So serious, in fact, that he developed a gun that actually takes standard 8.5 x 11 in computer paper and folks it into quality paper airplanes that soar through the air, neutralizing every enemy within two feet.

How To Recycle HDPE Plastic The Easy Way


After spending 2 hours cutting up a single milk bottle with kitchen shears, I knew I couldn't do it again.
I felt like a late night infomercial and may have actually uttered the phrase, "There has to be a better way!"
Turning old milk jugs and bottle caps into useable stock for making. In this short video I process a 2 milk bottles and about half a dozen bottle tops into a 1 1/2" x 3" x 5" turning block.

You could just as easily press this into sheet material for use in box inlays or scroll saw art. The possibilities are endless. The total processing time was under an hour from bottle to blank! Less than waiting for a glue up!
The result is a stunningly colorful blank ready for some new project!

Livros sobre Propriedade Industrial, quantos mais melhor...
O nosso amigo Aniceto Pires vem-nos convidar para o lançamento do seu Livro, "A Vacina Mecânica", um livro que reflete a sua experiência pessoal, de luta pelos Direitos dum Inventor, e quem puder, compareça ao Palácio dos Aciprestes, dia 22 deste Mês:

A Vacina Mecânica

Composto por um conjunto de desenhos, que ilustra, do que se trata como objecto da Patente de Invenção, que durante a ausência deste equipamento, trabalhadores, foram vítimas de acidentes, que deixaram marcas, alguns deles fatais, ao qual atribui o nome do Invento; “Pórtico Alberto”. Abertura e fecho automático das portas dos contentores de acondicionamento de gás embalado.

Um PC na Lancheira, ou uma Lancheira PC, eis um Instructable que não deixa de chamar a atenção!
Usando a famosa placa RaspberryPi, eis algo para fazerem com uma, que não necessita grandes esforços, nem informáticos nem de Hardware, o que faz um grande primeiro Projecto com a Raspi!

Lunch Box Computer with Raspberry Pi

This is a quick and easy project to build a portable Raspberry Pi computer that fits right in a lunch box. It's a good first Pi project since it requires no coding, soldering or tooling of any kind. All you have to do it acquire the parts, plug everything in and secure it in the lunch box.
The Raspberry Pi isn't a very fast machine, but it IS extremely versatile and easy to use. This rig will have all the functionality of a wifi netbook, if a slow one with a very small screen.

There are lots of ways to do a project like this so feel free to deviate from my plans. All of the parts are modular and you can change its abilities a bit by using different parts.
EDIT: While I used a Raspberry Pi model B in this instructable, I would advise folks to use the Model B+, it uses less power than the Model B which sometimes can't run both the Wifi and Bluetooth dongles.


Atenção, pessoal dos Cursos de Engenharia, Engenheiros já feitos, e Designers e Engenhocas em geral, podem agora medir a curvatura duma peça com este interessante Aparelhómetro, que podem fazer em casa:

Get started with the Bend Sensor

We started by looking at how the Bend Sensor is buildt up, and how it works.
We then looked at different areas we can see it beeing used in.
Finally we made a lamp were you can change colour of the light, and also the brightness of a LED.
You will find the steps of how to make your own lamp, including code and fritzing wireing at the end.

...E aos estrondos, entrou, de repente, esta maravilhosa Maluqueira, Paintball com estes Monstros vindos da Ficção Científica, para uns belos momentos de Apocalipse Geek...


Megabots: Paintball with giant robots

David Szondy

Who hasn't looked at a sporting event and thought that it would be better if it involved giant robots wailing on each other? That seems to be the thinking of the people behind the MegaBots Kickstarter campaign, who are raising money to build giant humanoid robots with human drivers to take on each other in paintball arena games.
A MegaBot is the sort of robot that stands out in a crowd. Run by a driver-and-gunner team, the 15-ft (4.5-m) tall walking robot weighs 15,000 lb (6,800 kg) and has modular arms tipped with pneumatic guns firing 3-lb (1.3-kg) paint MegaBalls at 120 mph (193 km/h). According to the makers, it’s clad in customizable breakaway armor plating that flies off when it takes a hit while, like a videogame, a computer keeps track of "damage" and makes the robot eject limbs, limp, make noise, and jam its weapons as the hits mount.
