Nexen Enhances Roller Pinion System With Increased Torque Capacity

Editor Design World

Nexen Group, Inc. has improved its revolutionary Roller Pinion System (RPS) by significantly increasing its torque capacity. With up to 60 to 140 percent more torque capacity*, the RPS offers industry-leading power density for precision linear motion control applications.

“In the past, the market has used the phrase ‘power density’ to differentiate similar motion control solutions,” said Tony Kliber, Lead Project Engineer Precision Automation Components, Nexen Group, Inc. “The new torque capacity ratings eliminate this factor, allowing our customers to reduce the size, cost and weight of their machines without sacrificing superior linear positioning performance.”

Nexen’s RPS offers linear positioning with zero backlash for high-precision motion control applications. With more than 99 percent efficiency and a long operational life of up to 60 million pinion revolutions, the RPS yields up to 36 million meters of travel. Differing from a traditional rack and pinion system, the RPS features a roller pinion/toothed rack combination. The pinion is comprised of bearing supported rollers that engage a unique tooth profile. Each tooth profile is measured to ensure high positional accuracy and eliminate cumulative error. Racks are available in standard 1-meter and ½-meter cut lengths or can be custom cut to certain lengths, leaving no limit to travel distances.

The Best Gingery Lathe Video Series To Date

Gerrit Coetzee

Makercise] has been working on a Gingery Lathe since September last year. His videos on the process are by far the most detailed, clearly shot, and complete series on making a Gingery lathe we’ve come across.
For those who aren’t familiar, the Gingery series of books describe how to build an entire machine shop’s worth of bench top tools using only the hardware store, dumpster dives, charcoal, and simple skills. The series of books start out with the charcoal foundry. [Makercise] has built a nice oil fired foundry already so it’s off to the next book, Gingery 2, is the metal lathe.
The Gingery books and, really, most DIY books from that era are: not well laid out, well written, or even complete. All but the most recent prints of the series still looked like photocopies of typewritten documents with photos glued on. The series provided just enough detail, drawings, and advice to allow the hobbyist to fill in the rest. So it’s really nice to see someone work through the methods described in the book visually. Seeing someone using a scraper made from an old file on aluminum to true the surface is much more useful than Gingery’s paragraph or two dedicated to the subject.

Build Your Own (metalworking) Lathe - Part I
corradini

You can make an entire machine shop worth of power machine tools, using basic hardware store/home center supplies and scrap metal. Melt aluminum in a metal-pail furnace, using sand, charcoal, and a clay flowerpot! Cast sophisticated metal tool parts using supplies from a gardening shop and modified kitty litter! End up with a full machine-shop lathe ("the only tool capable of making any OTHER machine-shop tool, including itself!") for just the cost of your time, some scrap steel and aluminum, and a motor!

Customizing Indoor Wireless Coverage via 3D-Fabricated Reflectors
Abstract

Judicious control of indoor wireless coverage is crucial in built environments. It enhances signal reception, reduces harmful interference, and raises the barrier for malicious attackers. Existing methods are either costly, vulnerable to attacks, or hard to configure. We present a low-cost, secure, and easy-to-configure approach that uses an easily-accessible, 3D-fabricated reflector to customize wireless coverage. With input on coarse-grained environment setting and preferred coverage (e.g., areas with signals to be strengthened or weakened), the system computes an optimized reflector shape tailored to the given environment. The user simply 3D prints the reflector and places it around a Wi-Fi access point to realize the target coverage. We conduct experiments to examine the efficacy and limits of optimized reflectors in different indoor settings. Results show that optimized reflectors coexist with a variety of Wi-Fi APs and correctly weaken or enhance signals in target areas by up to 10 or 6 dB, resulting to throughput changes by up to -63.3% or 55.1%.

Build Your Own Inexpensive Powerbank with 3D Printing
Matthew Mensley

Instructables user Nematic! details how to make your own portable powerbank from laptop cells, 3D printing and a little electronics savvy.
We’ve all experienced that unique feeling of helplessness and anguish that only a dead cellphone battery can bring. Cut off from the internet and contact with others it becomes impossible to navigate, and what the heck are you supposed to do while sitting around waiting for the bus/train/plane. It sucks.
Fortunately there’s no shortage of inexpensive power banks knocking around to keep you topped up with juice on your travels. But for the thrifty with time to kill and a handful of old laptop batteries lying around (a common scenario, we know) there’s an alternative.
In a short-and-sweet post over on Instructables, user Nematic! shows us how with nothing more than a few tools (3D printer, soldering iron and glue gun), a cheap powerbank module and some 18650 cells, you can make your own smartphone powerbank lickety-split.

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.

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.

Solder Sleeves
Solder, heat shrink and waterproof your splices in one operation.

This is the easiest way to make soldered splice in your wiring. It is our favorite way to extend the wires on stepper motors.
This part combines a low temperature solder ring inside a piece of clear heat shrink tubing. It also has rings of hot melt glue at each end. You strip each wire, insert one from each end and cross the stripped ends inside the solder ring. You then heat the tubing with a heat gun. The solder and glue melts and the tubing shrinks. You get a reliable, insulated, waterproof and soldered connection in one operation.
It is also great when you need to fan out one wire to several wires. This often happens when you have one ground terminal, but four wires coming to it. Place the four wires in one end and one in the other end.

Next Thing Co. Releases “World’s First” $9 Computer

David Scheltema

Snuggly situated in an industrial section of Oakland, CA is Next Thing Co. a team of nine artists and engineers who are pursuing the dream of a lower cost single board computer. Today they’ve unveiled their progress on Kickstarter, offering a $9 development board called Chip.

The board is Open Hardware, runs a flavor of Debian Linux, and boasts a 1Ghz R8 ARM processor, 512MB of RAM, and 4GB of eMMC storage. It is more powerful than a Raspberry Pi B+ and equal to the BeagleBone Black in clock speed, RAM, and storage. Differentiating Chip from Beagle is its built-in WiFi, Bluetooth, and the ease in which it can be made portable, thanks to circuitry that handles battery operation.

Make Your Own Injection Molding Machine

John Hannon

Tried, true, and totally doable. Start cranking out solid thermoplastic parts.

Sometimes there’s a tool you want to buy, but you can’t justify the cost. In that case, why not make it? For me, a plastic injection molding machine fell into that category — and it turns out they’re not hard to make.

I wanted to make solid plastic parts for some of my amateur science experiments. There are a number of ways to make things out of plastic, each with its advantages and disadvantages. Often just cutting raw material to the desired shape works best. Some plastics can be cast by pouring a liquid resin with hardener into a mold (see “DIY Rotocaster,” Make: Volume 41). Vacuum forming works well for making things out of thin sheets of plastic (see “Kitchen Floor Vacuum Former,” Make: Volume 11). I considered making a 3D printer, but for the few plastic parts I envisioned needing, it wasn’t worth the time and money.

Plastic injection molding has been around since thermoplastics were invented. It’s a great way to make many copies of a part quickly, and what I like best is that it’s easy to reuse old plastic objects to make new ones.

So I built an injection molder based on the plans in Vincent R. Gingery’s book Secrets of Building a Plastic Injection Molding Machine. David Gingery could be considered a forerunner of the Maker Movement — he and his son Vincent have written a whole series of books on building tools for the machine shop.
