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

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.

I think we all know this will be used against us. The NWO is upon us everyone. Don’t take the mark or the beast and please repent while there is time. Jesus is the only way.

I have to admit that I do like the feel of a classic (preferably vintage) toggle switch -- I also like the fact that in modern TV series like Cowboy Bebop (https://www.netflix.com/title/80207033) we see a mix of modern (spaceships) and vintage (control panels replete with toggle ...

In university, I didn't do so hot in thermodynamics, so this article is welcome. BTW, some great engineering design approaches and equations for thermal management available from heat sink vendors (Wakefield, Vicor) &c.

" 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

Good article. Brings back a flood of memories of when I was a "digital" chip designer at Cal-Tex Semiconductor (purchased by Fairchild) during those times.

I do not know why this level of technology poses as consumer gear, except that it's built down to a price. User interfaces in the form of buttons and displays cost money.

logical and complete user control with fully-defined function is the design philosophy that I would not mind paying for and would gladly endure more clunkiness in the implementation of....instead, user control is minimized and awkward if it is not toward a purchase decision with wireless in the linkage and ...
