Just to ensure we’re all tapdancing to the same drumbeat before we leap into the fray with gusto and abandon, let’s briefly remind ourselves that in Part 1 of this miniseries we introduced the concept of switch bounce. Later, in Part 2, we took a deeper dive into the bouncing associated with a single pole, … Read More → "Ultimate Guide to Switch Debounce (Part 5)"

With the COVID-19 situation continuing to evolve, numerous companies in our industry have been telling their employees to work from home (WFH) lately to enable “social distancing” to slow the spread of the virus. Large numbers of engineers, marketers, and other technology professionals may find themselves hanging out on the sofa, trying to squeeze out … Read More → "Work from Home Survival Guide"
It seems that almost every day I hear about some cool and exciting techno-wonder originating with those clever guys and gals in Israel. For example, I currently have a WifiWall Traveler sitting in my shirt pocket. This little beauty, which came from the folks at WifiWall.com, is small enough to fit in the palm of my hand (2.5" x 1.75" x 0.75"), yet it's awesome in its power.
I was recently introduced to the concept of Engineers Week (EWeek), which was founded by the National Society of Professional Engineers (NSPE) in 1951. This year, EWeek took place 16-22 February. Of particular interest to me was Introduce a Girl to Engineering Day (a.k.a. Girl Day), which was celebrated on 20 February 2020. According to … Read More → "Introducing Girls to Engineering"
Previously, as they used to say at the start of a new episode in a TV series, we discussed the history behind the use of hardware vs. software to debounce our switches. We also perused and pondered the idea of using an RC network followed by a Schmitt trigger to debounce a single pole, single throw (SPST) toggle switch (see Part 3).
In Part 1 of this miniseries, we introduced the concept of switch bounce; that is, when we open (deactivate) or close (activate) a switch, it may make multiple transitions before eventually settling in its new state (see also my Switch Types and Switch Terminology columns). We also noted that this occurs in toggle switches, rocker … Read More → "Ultimate Guide to Switch Debounce (Part 3)"
As we discussed in Part 1 of this miniseries, when we operate a switch, it may bounce multiple times before coming to rest in its new state (see also my Switch Types and Switch Terminology columns). This is caused by the fact that the contacts in switches are usually made of springy metals. When they … Read More → "Ultimate Guide to Switch Debounce (Part 2)"
As I mentioned in a recent column — [Electronic] Ghosts of Christmas Past and Future — the fact that we have just drifted into the year 2020, which means we are now 1/5th the way through the 21st century, is giving me pause for thought about how fast technology is changing. Take a moment to … Read More → "Not Your Grandmother’s Embedded Systems"
In my previous column — What the FAQ are CPUs, MPUs, MCUs, and GPUs? — we discussed the fact that the electronics industry is replete with acronyms, especially the three-letter variety. We also noted that we tend to learn a lot of things by osmosis, gradually (often unconsciously) assimilating nuggets of knowledge into a conceptual … Read More → "What the FAQ are ASICs, ASSPs, SoCs, SOMs, etc.?"
I’m sure you know what the terms CPU, MPU, MCU, and GPU stand for. I’d wager you think you know which functional blocks each of these terms embraces. But are you 100% certain? Would you bet on it? One of the problems we have in the electronics and computing industries is a surfeit of TLAs … Read More → "What the FAQ are CPUs, MPUs, MCUs, and GPUs?"
