ELECTRONICS: Electronic components distributor Digi-Key Corp. is now stocking C&K Components’ ELUM Series switches. Designed to eliminate the need for separate LEDs and light pipes on printed circuit boards, these switches feature a 6 mm profile and are available in through-hole and surface-mount configurations. The ELUM features silver- or gold-plated contacts that range in ratings from 0.01 to 250mA and from 20mV to 50V dc. The latching version (push-push) can be specified for switching functions such as mode select and power on/off, while the momentary version is ideal for test, reset and notification functions. The ELUM Series device is one of the only push-button switches designed so the LED travels with the actuator, ensuring even distribution of light. The compact design saves space on the PC board, enabling product miniaturization and greater onboard functionality. ELUM Series switches are RoHS-compliant and compatible with high-speed reflow soldering processes. The 30,000-cycle life expectancy makes the push-button devices ideal for telecom, industrial, medical, automotive and consumer electronics applications.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
