ID/OD Retaining Ring Lock
Spirolox Retaining Rings can operate in an internal and external groove at the same time. Install the ring in one groove and then compress the ring with the mating component into the second groove. When the grooves meet, the ring snaps into place creating a low-cost, hidden, high-strength, tamper-proof rotating joint. Over 6,000 rings are stocked from 1/4” to 16” diameters in carbon and stainless steel, customs up to 120”.

Porsche takes a look back at its four-cylinder engine history
The market launch of the new Porsche 718 Boxster last July represented the first time since the late 1960s that Porsche is cranking out sports cars with four-cylinder flat engines. The launch presents a nice opportunity to take a drive down memory lane through Porsche's four-cylinder engine history.

Metallic glue may stick it to soldering and welding
A team of researchers at Northeastern University has created a glue made out of metal that sets at room temperature and requires very little pressure to seal. MesoGlue "is like welding or soldering but without the heat,” says Hanchen Huang, a professor and chair in the Department of Mechanical and Industrial Engineering, who created the substance with two PhD students and started a company to feature it.

No. 1 Mike Likes 2016: ABCs of gears and more
KHK USA takes you on a journey through the history and applications of gears in two information-packed free volumes called "The ABCs of Gears." Part A is aimed at beginners, while part B moves on to intermediate fare, such as types of gears and tooth forms, heat treatment, surface treatment, production methods, etc. Another mid-level text called "Introduction to Gears" and an in-depth "Gear Technical Reference" are also available, chock full of materials information and calculation examples and tables. Best of all, there is no registration for any of these valuable no-cost PDF resources.

Top Mike Likes: Intel drone developer kit
Pre-orders are open for the Intel Aero Platform for UAVs. Designed from the ground up to support drones, the $399 UAV developer kit is powered by an Intel Atom quad-core processor. It combines compute, storage, communications, and flexible I/O in a form factor the size of a standard playing card. When matched with the optional Vision Accessory Kit, developers can create sophisticated drone applications. Also available early 2017: Intel's Aero Ready To Fly drone, a fully assembled quadcopter with compute board and integrated depth and vision capabilities.

Chairless exoskeleton solves long-standing problem

The Chairless Chair is a new solution for relieving strain and fatigue from excessive standing during long work shifts. The entire construct is lightweight, easy to put on, and hardly noticeable when walking. By operating a switch on the strap, the flexible construct turns into a stable seat. Two small DC motors activate a stop valve in the hydraulic elements of the shock absorbers, locking the support into the seated position.

A look at ion propulsion technology

Ion thrusters are being designed for a wide variety of space missions -- from keeping communications satellites in the proper position to propelling spacecraft throughout our solar system. These thrusters have high specific impulses (ratio of thrust to the rate of propellant consumption), so they require significantly less propellant for a given mission than would be needed with chemical propulsion. Here's a look at how they work.

No. 1 Product: Robotics modular kit for low-cost automation
The Robolink D modular robotic kit from igus allows users to assemble custom robotic systems for a range of applications. Separate joints, which are motor-driven directly on the axis, are available in a range of installation sizes. A new, 6-axis arm with strain wave gearing (in two installation sizes) is also available, along with universal gripper adaptors. The gearing, available as an individual component or with integrated NEMA motor, consists of an outer ring gear and flexible, wear-resistant inner ring gear made from self-lubricating, wear-resistant iglide plastic. This solution offers minimal backlash and ensures a precise adjustment with incredible smoothness.

Top Product: Nanocoating waterproofs electronics
Ever wonder how top name brands like Sony, Nokia, Agfa, and Skullcandy can crank out more and more products with better and better waterproofing characteristics? They turn to a Belgian company called Europlasma and its time-tested Nanofics line of plasma coating solutions. The company's Nanofics 120 family of coatings can be applied at the component level, PCB, or even the whole device, and is typically used to reach water ingress protection levels up to IPX4 (splash of water for 5 min.), and salt mist corrosion protection for at least 48 hours. A new ultra-thin version allows electronics to survive full water submersion while powered on, reaching IPX7 (immersion in water up to 1 m for up to 30 min.) or higher.

Videos+: Technologies and inspiration in action
Two-seater electric helicopter takes first flight
Germany-based e-volo’s emissions-free Volocopter VC200 took its first official manned flight in April 2016. The all-electric flyer is made of a lightweight, fiber-composite material and features 18 rotors with motors driven by nine batteries. With a 450-kg take-off weight, the VC200 requires about 45 kW to hover, depending on the air pressure/temp. Its built-in multiple redundancies help ensure stability, even if parts of the system fail, and make the unit easy to fly using only a joystick. Unlike a helicopter, the blade angle on the VC200 cannot be adjusted. The amount of thrust produced depends solely on the rotation speed of the rotors. The copter received its permit to fly as an ultralight aircraft from German aviation authorities in February 2016, and NASA invited e-volo to present the technology at its On-Demand Mobility workshop in Washington, DC, this past March. And did we mention it folds up too?

5 fun, easy project ideas you can try with a
$35 Raspberry Pi

Patrick Norton from Digital Trends scratches the surface of cool things you can do with a Raspberry Pi, that $35 credit card-size computer board that makers and budding science geeks love. Why not make a vintage arcade console, an ad blocker (called a Pi-Hole) for your home network, or a DIY streaming box for your HDTV? Raspberry Pi boards and accessories are available at element14.

You crushed it! See stuff get smashed
Some enterprising guys in Finland with a penchant for smashing stuff have created their own Youtube channel -- and they want to share all the fun. “Wanna see stuff getting crushed by a hydraulic press?” they ask. This is the right channel for you. From cameras to ice to an old safe, a ball bearing, a running four-stroke motor, a motorcycle helmet, and more, take a few minutes out of your day to feel like you crushed this one.
