Unit Conversion Tool Convert popular spring units such as force or retaining ring thrust capacities into metric units with Smalley's engineering tools. Simple tools allow for units to be converted such as mass and weight, angular measurements, velocities, temperatures, pressures, and more. Other tools allow engineers to design custom springs and retaining rings.

Mike Likes Extra: Raspberry Pi -- this educational toy is not a toy So if you haven't heard of the Raspberry Pi single-board computing craze, well, it's never too late to jump into something really great. Eben Upton and his colleagues at the University of Cambridge's Computer Laboratory have come up with a $35 credit card-size Linux computer with 512 MB RAM "that plugs into your TV and a keyboard. It's a capable little PC that can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video." It is also incredibly flexible, design-wise, so makers and professional engineers alike can get really creative with little investment. A power supply or SD cards are not included, but they can be purchased at the same time in bundled packages. You can order one from Newark (link below). Check out raspberrypie.org and then get to Googling projects. I think you'll be pleasantly surprised.

Urethane-covered bearings, cam followers, and rollers Fixtureworks will be showing Fairlane Products' urethane-covered bearing, cam follower covers, and press-fit rollers at the 2013 PAC Show Feb. 12-14 in Anaheim, CA. Urethane-covered bearings have a smooth surface that is cast directly to a precision sealed ball bearing, providing a smooth, quiet, and non-marring operation. Cam follower covers have a smooth urethane outer surface that is permanently bonded to a steel insert. They are designed to be press fit onto standard cam followers to prevent metal-to-metal contact and damage to finished or delicate surfaces. Press-fit rollers have a smooth surface, permanently bonded to a steel insert that allows for customizing the mounting configuration.

Ball guide screw linear rails Haydon Kerk Motion Solutions, a brand of AMETEK Precision Motion Control, has introduced the latest and final addition to the new BGS (Ball Guide Screw) linear rail product line. The BGS06 linear rail is a versatile system utilizing the popular size 17 single-stack or double-stack stepper motor linear actuator. Depending on static, dynamic, and moment load requirements, the product design engineer can now choose between 3 BGS frame sizes: the BGS04, BGS06, and BGS08. All BGS frame sizes are designed to position heavy loads and maintain repeatability and accuracy while withstanding significant cantilevered loading.

Cool Tools: Tablet computing goes big time -- 27 inches big Lenovo unveiled its multitouch, multi-user IdeaCentre Horizon Table PC at the CES show in Las Vegas Sunday. What's so huge about that? Well, the tablet size, for one: 27 inches of Windows 8 high-performance desktop computing that would sit nicely on your coffee table serving as game-play or design central (at 17 lb, you have to put it down somewhere). For those who are nonplussed with the size, the company is also working on a 39-inch widescreen version. Can't wait to see the carrying case for that one.

| Tiny, 8-axis micropositioner used for precision optical alignment in a new handheld instrument | |
| New Scale's latest micro-positioning system fits eight axes of motion into an 80-mm space and runs on 3.3 V. Drive electronics are integrated right into the module; there's no external control board. It accepts high-level motion commands directly from your system processor over an I2C interface. This implementation solves an optical alignment problem in a new and highly miniaturized instrument. New Scale applies the same design skills and micro-mechatronic expertise to just about any positioning application that requires small, precise, and smart motion.
