David explained Freescale developed this microcontroller (MCU) primarily for portable and industrial devices that can benefit from low power consumption and the capability to drive... MoreLink This | Email This | Comments (26) Where Are the Inexpensive-But-Useful Design Tools?Recent information from a company pitched a new net-list editor at a cost of $5000, and that was a special introductory price. I have seen prices in the multi-thousand-dollar range for a variety of software-development, circuit-simulation, and circuit-design tools. That made me wonder where engineers can find low-cost yet capable tools for design work. Of course companies offer free software... MoreLink This | Email This | Comments (1) Miniature Motor Squiggles into Small Precision DevicesLook at small motors for a product design and you’ll find a gap between small DC motors and micro electromechanical systems (MEMSs) fabricated on a silicon wafer. New Scale Technologies has helped filled that gap by designing squiggle-motion motors, or squiggle motors, for engineers who need a tiny motor in miniature and subminiature applications. You can find out more at:...

I don’t like to waste a decent AC motor that might find use in my workshop. The pump arrived in a plastic-foam enclosure that included a control panel and an AC power cord. I pulled apart the enclosure and found a set of pipes and electronics. An aluminum box that contains the electronics... MoreLink This | Email This | Comments (2) Single CMOS Image Sensor Sees in 3-DAn email arrived from Canesta, a company that I hadn’t heard of, so I went to the Canesta Web site where I learned the company makes 3-D CMOS image sensors. You can buy or design 3-D vision systems with off-the shelf cameras, but most of these systems use off-axis laser beams or several cameras to grab images that intensive software processing turns into a 3-D image. That means they... More |

Light Matters: The Unsung Heroes of
Modern Health Care
First, let's define "no-compromise." In an ideal configuration, this lamp would use a high-brightness LED (HBLED) that is built into a small, integrated package and is able to produce a large quantity of focused light, operate with a high level of reliability and generate no audible noise. Is this difficult? Yes, but it is possible.
