In this week’s podcast, super tiny technology is taking center stage! First up, I check out world’s first and smallest sensor that can enable touch gestures through any material. Dan Goehl (Co-founder and Chief Business Officer at UltraSense Systems) joins me to discuss how UltraSense’s new 3D ultrasound sensor is going to usher in a whole new era in user interfaces. Also this week, I investigate … Read More → "Changing the UI and UX Paradigm Once Touch at a Time"

Happy 50th Birthday to the Signetics 555 Timer IC

A Tribute to Hans Camenzind, an Extraordinary Analog Engineer
by Steven Leibson - January 10, 2022

Signetics announced the NE555 timer/oscillator IC in 1972, 50 years ago. Over five decades, this simple 8-pin chip has consistently sold in the billions, each year. It’s a perennial hobbyist favorite. Well-known authors such as Walter Jung wrote 555 timer cookbooks, and 555 circuits have been popular for new circuit designs since the 1970s. Engineering acceptance has been mixed. Some engineers routinely put 555 chips in their circuits. Others … Read More → "Happy 50th Birthday to the Signetics 555 Timer IC"

Software and Automotive Safety

Sponsored by Siemens Digital Industries Software

In the realm of automotive designs, safety must reign above all else. But the question remains: How can we innovate within the constraints of today’s safety standards? In this episode of Chalk Talk, Amelia Dalton chats with Rob Bates from Siemens about the role ISO 26262 plays when it comes to COTS and open source software, what certified software components are all about, and how heterogeneous multiprocessing can be helpful in your next automotive design.

How an SoM accelerates and simplifies processor-based designs

Sponsored by Texas Instruments

If you're comfortable working with integrated circuits that have four to 48 pins, building a custom printed circuit board (PCB) for a new product might make sense. But when your design is complex—think: processor with more than 300 pins, DDR memory, eMMC, complex physical layout, and all the electrical considerations that go with it—a simpler, lower-risk, off-the-shelf product is often a better solution. Discover the benefits of a system-on-module (SoM) for complex, high-pin-count PCB designs.

" actuation actuated " feedback ( which clicky-feel does inherently ) saves me from personal aggravation at being forced to wait on the dumb bucket of bolts, presumably to appreciate agape the digital wonder of it all even from the list of feedback second-bests ( display, beep ), the control is tolerable if not too awkward
