Tinijet — Affordable Waterjet Cutting At Home

James Hobson

While laser cutting remains the dominant force for rapid prototyping anything made of plastic, MDF or wood, the real holy grail is the ability to cut metal — something most laser cutters are just not capable of.
In the industry, this is done using extremely high-powered laser cutters, plasma cutters, or water jet cutters. All of which are very pricey equipment for a hacker. Until now anyway. Introducing the Tinijet, the missing tool for affordable water jet cutting.
We first covered this project a few years ago when it was just a university research project called Hydro — it’s since evolved immensely, and will be available for sale very soon.

DoggoBot Version 1
makerinchief

Ever since I started programming Arduinos, I wanted to build a robot using one. I also want a dog. However, living in NYC makes it tough to take care of a dog. So after hours of watching videos of robots and dogs, I decided to put my phone down and build myself a pet!
I present to you find readers, DoggoBot Version 1! I created a 4 legged walking bot which can be build with cardboard and hotglue. The electronics are simple and can be ordered from Amazon. However, I noticed the links from Amazon tend not to last very long so the links provided are from websites which routinely carry the items. If you want to get them from Amazon, simply enter the name of the item in the Amazon search bar. You can definitely get a lot of these items cheaper on Amazon then directly from the websites provided.

GO THERE!

Marblevator Mini, Loop.

gzumwalt

I had to dust off my physics textbook for this one...

How fast is too fast for a marble machine? Well, check out the video "Marblevator Mini, Loop, High Speed Test", at 324,000 marble runs per day, it is indeed the fastest marble machine I've ever designed.

"Marblevator Mini, Loop" is not quite as "mini" as my previous Marblevator Mini designs, but is still quite small, and features a 7.5mm radius loop with a tapered auger lift. Using a few relatively simple physics equations, the height of the entrance ramp (H) is determined by the simple equation H = 2.7R (where R is the radius of the loop). My desire to keep the model small determined the loop radius (7.5mm) and ball bearing diameter (8mm). And to add friction compensation, especially for a 3D printed track printed in this orientation, I increased the height of the ramp over the calculated height of (2.7 * 7.5mm) or 20.25mm.

In the video "Marblevator Mini, Loop Stress Test", the stress test ran over 29 hours and is still running. The auger rotates at approximately 75rpm which in this test translates to 75 marble runs per minute. At this rate, Marblevator Mini, Loop has executed (29 * 75 * 60) or 130,500 marble runs without loosing a marble.

Measuring Success: Maker Crushes Kickstarter Goal By 2,087%
Lisa Horn

The Secret Behind The Elegant Instrument That Measures The Golden Ratio
Sir Edward Victor Appleton, 1947 Nobel Laureate in physics, said: “The golden ratio is the key to universal physics.” And for Scott Onstott, founder of SIPS Productions Inc., the golden ratio is the key to a Kickstarter campaign success story that had this maker crushing his initial goal to raise $1,618 by 2087%.
The Golden Ratio Is Everywhere (Even If You Don’t Know It)
From great works of art down to the credit card in your wallet, the golden ratio is everywhere. In mathematical terms, the ratio is 1:1.618. While these numbers may not hold much meaning to the casual observer, they have been studied by scholars for centuries.
“Some of the greatest mathematical minds of all ages, from Pythagoras and Euclid in ancient Greece, through the medieval Italian mathematician Leonardo of Pisa and the Renaissance astronomer Johannes Kepler, to present-day scientific figures such as Oxford physicist Roger Penrose, have spent endless hours over this simple ratio and its properties,” says Israeli astrophysicist Mario

Visual 3D Print Finishing Guide
Tom Nardi
With 3D printers now dropping to record low prices, more and more people are getting on the additive manufacturing bandwagon. As a long time believer in consumer-level desktop 3D printing, this is a very exciting time for me; the creativity coming out of places like Thingiverse or the 3D printing communities on Reddit is absolutely incredible. But the realist in me knows that despite what slick promotional material from the manufacturers may lead you to believe, these aren’t Star Trek-level replicators. What comes out of these machines is often riddled with imperfections (from small to soul crushing), and can require considerable cleanup work before they start to look like finished pieces.

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.

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.

steelcase X MIT create customized furniture by 3D printing into liquid gel 

up until now, 3D printing has been a desirable yet limited tool for manufacturing. whilst great for creating small, one-off objects, the technique has long needed to be adapted to be used on a large, commercial level. with this in mind, scientists at the MIT self-assembly lab have collaborated with the global furniture brand steelcase and acclaimed product designer christophe guberan to yield a 3D printing breakthrough—piloting a new process dubbed rapid liquid printing. the technique allows for the creation of large scale objects in just minutes, and is poised to make large-scale manufacturing of customized furniture a reality.

Take The Mystery Out Of Laser Engraving Costs With This Price Comparison Tutorial

Lisa Horn 

Laser engraving: It turns basic laser cut designs from ordinary to extraordinary. But this added style, beauty and impact can significantly increase your design costs. To be able to achieve excellent design while staying on budget, you’ve got to get smart.

This means you’ve got to get smart with how files are built…and this may take some detective work to determine exactly where there are opportunities to tighten up a design that saves time—and money.

But does getting these laser engraving costs just right seem like a mystery that can’t be solved? You don’t have to be Maxwell Smart, Inspector Clouseau or 007 to solve this case. We’ve done all the legwork for you…and it didn’t require a clandestine impossible mission or an enigmatic decoder machine to get the files.

Ultimate Third Hand

Franklin7993 

What is a third hand?

A third hand is a devise used to hold something in place while work is being performed. It is essentially a third hand to aid your two hands. It is like having someone else’s hand to help hold something that you are working on. With the aid of another hand to steady your work you can perform the task that you are doing with a steady hand.

You can use a third hand to hold parts while using a torch to heat the parts and solder them together.

A third hand is useful to hold parts in place when using a soldering iron to make a join.

A third hand is very helpful when gluing parts together. There are dozens of other uses.

Essentially a third hand holds items in place while you work on them.
