SUREFLY! OOOOHHH, YEAH! E Engrenagens, a Roda de Genebra, um Instructable meu, 19(!) Programas CAD, e um Professor e seus Relógios

EU QUEEEERO!

Desde que apareceu o primeiro Quadracóptero que andava à espera que isto aparecesse, e agora...

Já cá tá!

E atenção, este veículo, não é uma carroça que se pilota a ela mesma, o que seria extremamante perigoso, pois podia até aterrar calmamente num Edifício em chamas.

É pilotável, cabe numa Garagem, e estará à venda em 2019:

The Surefly is Your Personal Octocopter That Flies Like a Drone and Can Even be Parked in Your Garage

The time has come. After 78 years, the helicopter has been reinvented. SureFly is a personal helicopter/VTOL aircraft designed for safe and easy flight.

Podem ver uma bela duma Roda de Genebra, na imagem acima, e se precisam de cortar ou imprimir uma, com N passos, pois não têeem mais do que seguirem este meu Instructable, que vos permite visitar um Site onde se calcula tudo para as rodas, e se cria um Modelo, que podem animar.

Daí, é um processo simples, que eu explico, para sacar esse modelo e transformar as imagens em desenhos Vectoriais, que podem depois mandar cortar por laser, ou imprimir em 3D:

Geneva Wheels À La Carte, to Sgv

Edgar

What Gizmo maker won't, some day, need a Mechanism that will transform a continuous rotation into a move-pause-move one?
That's the Geneva Wheel!

And the question is, where do you get a Vector Drawing of the parts, so you can Laser cut/3D print/machine from a template/whatever?
I've managed to make these parts in sgv format, from an Online Geneva Drive Generator, great program, highly configurable...

But I've not got an Svg directly! No such luck...
I've managed it by snapshotting that page, and then using both Gimp and Inkscape, to make Vector drawings of those parts.
And that's why I've made this Instructable.

Gears and Gravity: Finished Clocks (Day 13)

J. E. Johnson

Wow, took me long enough to post this. The last day of DEEP camp on June 28 and I learned so much from my students that I’ve been completely absorbed in revising the clock design that I haven’t taken time to post the photos of my student’s truly excellent work. Can’t wait for next year.
The video below shows six cardboard clocks running (mostly) all at once. What a lovely sound.

Engineering the "Swiss-army knife of robots"
Kristin Hanson

The Cohen Translational Engineering Fund is helping promising startups like READY Robotics bring their innovative technologies to market as quickly as possible
...
"The Cohen funding allowed us to see how our product would solve problems in real-time, and how it could provide value, rather than just existing in the lab as a research toy," Guerin says.
Now READY Robotics' president and chief technical officer, Guerin calls the startup's product, TaskMate, the "Swiss-army knife of robots."

The company installs its software in a pre-made robot, making the machine easy to program and adjust — similar to how Microsoft made personal computing accessible to non-programmers with software like DOS and Windows. Once trained in the system, users can switch the tasks their robot performs in minutes or hours instead of days or weeks and cut out the cost of an outside programmer.
After using the Cohen grant to build and test a READY Robotics prototype, the technology earned a $100,000 Maryland Innovation Initiative grant from TEDCO — the Maryland Technology Development Corporation — and then raised $3.75 million in seed funding. Since opening for business officially June 2016, READY Robotics has grown to house 12 employees in its South Baltimore office, and Guerin and his team have kept busy testing prototypes with manufacturers and attracting more investors and customers.

Your Guide To Making Electronics Project Boxes

DJ Harrigan

Introduction To Electronics Project Boxes
 

You’ve just made something great: It blinks, it whirrs, it speaks in tones, it’s voiced-controlled and it’s “cloud connected” (of course). And now this assembled heap of your own design is waiting on your desk for the final touch. If you want to keep your electronic creation alive for years to come, and draw fewer eyes as you ferry it through airport security, you’ll want to make a robust electronics project box to house and protect it.
The benefits of a small electronics case are clear: Your project will last longer, work more reliably and demonstrate a detailed attitude about showing off your work. It’s time to think outside the box when it comes to thinking about the insides of boxes.
But where to start? Where to finish? This post will guide you through the many different kinds of materials, joinery and aesthetic options for your electronics project enclosure.

$1 Inflatable Sander Replacement DIY

johnzhu

Inflatable sanders are problematic, leakage being a problem with anything full of air. I decided to make a replacement from a piece of dowel, some velcro, and a bolt. The cost is less than $1. I really like the resulting round sander, and I hope you find it useful too.

Um Engenhocas vai sempre ter de medir a força dos seus Ímanes e Electro-Ímanes, por isso, saibam como o podem fazer com precisão:

Gizmo Makers will all eventually get to need to measure Magnetic Fields, of their static and electro-mangetic Magnets, so learn how to do that accurately:

Measuring Magnets 

We like to use this blog to answer common magnetic questions in a bit more detail.  Here we can provide a fuller explanation than might be possible in an email or brief conversation.  It’s also nice to share this kind of stuff online so people can find it for themselves while searching!

In this installment, we’re going to focus on questions about measuring the field strength of a magnet.  Perhaps the most common question is:

I’m measuring the Surface Field of a specific magnet with magnetometer, and I’m measuring less than the specified Surface Field.  Why are my readings low?  Is something wrong with the magnet?

Let's dig down into the details and see how these measurements can be useful.  We'll also learn about what their limitations and pitfalls might be.

Dubai’s New Drone Laboratory is 3D Printed from Concrete

Matthew Mensley 

And the award for the most “the future is now” headline goes to this story, and the news that concrete 3D printing company CyBe has completed its first project in Dubai.

The Dutch firm has been working on the city’s new R&Drone Laboratory, one of a number of progressively technology-focused projects commissioned by Dubai’s numerous authorities.

Located in the desert at the city’s Solar Park, it will be home to exciting research facility. Exciting indeed, since 3D printing will be one of the areas of focus, alongside the building’s titular drones.

The Dubai Electrical and Water Authority, architects Wanders Wagner, engineering consultants Witteveen + Bos and construction firm CONVRGNT all have a stake in the project. But it is CyBe that planned and physically constructed the structure.

To achieve this the company used its array of proprietary, concrete-based products. This includes software, material and the CyBe RC 3Dp mobile printer.

Eis um simpático Robot Open Source, o Q.bo One, e é mesmo para todos, Programadores, Educadores, Hobistas, ou mesmo os mais novos!

Porque pode ser programando com um Interface de programação intuitivo, o Scratch, ou para Engenhocas mais sabidos, em  C++, Java, PHP ou Python, vai ser uma ferramenta bacana:

The Perfect Platform for Kids, Educators and Developers

Qbo Robot 

Q.bo One is built to be easy. It is easy to adopt because it is relatively inexpensive, it is easy to understand because it is interfaced with very simple parts and it is easy to build applications on because its hardware and software are open source.

Programming language such as C++, Java, PHP or Python can be used to program Q.bo One. Notwithstanding, those with little or no programming language experience can always start with Scratch. Scratch is easy to learn, so much so that even kids can pick it up. Essentially, Scratch is supported by comprehensive and interesting tutorials together with references and discussion forums to get the learner up to speed. It is designed to be graphical so that users can just pick and drop various modules to write a program. It similar to building a jigsaw puzzle, only that this time, instead of putting an image together, the user writes a program.

Quantas vezes já não vos falei do Torno Gingery!
Pois para vos inspirar a fazerem um, cá vai esta história de sucesso, para verem que sim, pode ser feito:

Re: Home made tools!

ndr1968 

Here’s my ultimate home made tool. My lathe! It swings 10.5” over the bed. Turns 24” between centers. Threads the full compliment of SAE threads. Has steady and follow rests as well as a Southbend inspired taper attachment. Yep, I cut all the change gears, made most of the tooling (except chucks) including a sector type dividing head with hole plates. This little lathe still turns with +/- .001” (or better) accuracy and I still use it on occasion. I completed it back in the late 90’s and as I recall it took me about two years of pretty much devoting every spare moment I had to it. 

I was inspired by the David Gingery book Metal Lathe. The book outlines detailed plans and instructions for building a small lathe from aluminum castings. I used no castings for mine but the shop lore and techniques in this little book were all I needed to understand the processes and basic machining skills needed to complete the project. Even if you have no intention of building such a thing the book is well worth looking at. Gingery is a genius of what I like to call “bootstrap engineering”. He takes scratch building to a whole new level. He has several other project books out including how to build a drill press, a shaper, a horizontal mill, sheet metal brake, dividing head, etc.
