Molded Nylon Special Standard Round Spacers
Micro Plastics announces a new product line of Special Standard Round Spacers. The new line of molded nylon round spacers includes over 250 sizes, with diameters of 1/8" through 1 1/2" and lengths from 1/8" to 2 3/4". These tough, resilient spacers can be used in a variety of assemblies. Useful in electronic and electrical applications, they may also be used as bushings, bearings, rollers, gliders, and bumpers. They are resistant to vibration, abrasion, and corrosion; are electrically insulating; and have a high strength-to-weight ratio.

Silicon-based nanoparticles could make LEDs cheaper, greener to produce
Researchers at the University of Washington have created a material they say would make LED bulbs cheaper and greener to manufacture, driving down the price. Their silicon-based nanoparticles soften the blue light emitted by LEDs, creating white light that more closely resembles sunlight.

NASA working on 'blue-collar' moon-digger robot

After decades of designing and operating robots full of scientific gear to study other worlds, NASA is working on a prototype that leaves the delicate instruments at home in exchange for a sturdy pair of diggers and the reliability and strength to work all day, every day for years.

Parallel mount kit from GAM Gear

Connecting to linear actuators just got even easier using the PMK (Parallel Mount Kit) from GAM Gear, which enables virtually any motor to be connected in parallel to any linear ball screw actuator, regardless of manufacturer. When there are space constraints on a machine design, the PMK can help save space compared to a typical inline motor mount configuration because the motor is to the side of the actuator. Available in four standard frame sizes from 3 in. to 6 in. (based on effective height), the PMK has maximum output torques from 2.4 Nm to 46 Nm in a 1:1 pulley transmission ratio. All PMKs are designed for universal mounting, which means they can be installed either horizontally or vertically without further specification.

Engineer's Toolbox:
Using disc springs in a heavy-duty power drill

When an engineer at quality power-tool maker DEWALT was tasked with limiting the maximum torque output of a high-power right-angle drill, he determined early on that the clutching thrust required in the space available could only be achieved by a disc spring design. Compared to conventional coil springs, disc springs offer a higher load capacity in less space. This article includes comprehensive disc spring design guidelines from SPIROL.

New friction calculator iPhone app

If you need coefficient of friction values for your engineering calculations, General Magnaplate's new Friction Calculator iPhone App can help. The new app provides static and dynamic coefficients of friction (COF) for more than 200 pairings of commonly used materials and engineered coatings. Friction Calculator's materials database is continually updated with new materials and coatings. Other features include surface engineering resources and friction engineering help. Use the online version until the Android version comes out.

The most compact drive on the market

The high-performance FAULHABER Series 1218...B Brushless DC Motor available through MICROMO is designed to address applications where high power and overall motor size are key requirements. Its 18-mm length makes it the most compact drive on the market in the 12-mm-diameter size. It has a wide standard operating temperature range from ‐20 deg C to 100 deg C. Based on the revolutionary System FAULHABER ironless stator winding design, the motor provides a reliable option for challenging fields of application such as medical pumps, robotics, and laboratory automation. This motor delivers continuous torque to 1 mNm and has integrated digital Hall sensor feedback. When combined with the wide range of FAULHABER planetary or spur gearheads, the output torque can reach 300 mNm.

A new spin on pneumatics: The AeroValve solution
AeroValve's innovative technology recycles compressed air through the valve body with each cycle of the valve, reducing compressed air requirements by more than 20 percent. Take a look at how this technology works, and see what it can do for you. AeroValve technology can be applied to approximately 60 percent of existing directional control valves.

One-wheeled motorcycle-like scooter
See the RYNO in action, a self-balancing, one-wheeled prototype electric scooter that lets you ride "in between the cracks of urban transportation." Chris Hoffman, RYNO's CEO and chief creator, says the scooter is "regulated in the city at 12.5 mph just like any other mobility scooter," but comes preloaded with way more fun. Although it still hasn't rolled into showrooms, the aim of the latest model is to "pack 4 horsepower into the wheel ... with 2,000 Watts of motor power, this thing will climb a wall." Twin removable, rechargeable battery packs provide an estimated range of 25 miles.
