Yes! This is it! At long last we’ve reached the final part of this epic saga into all things related as to why switches bounce and how to mitigate against this phenomenon; that is, how to debounce the little rascals. On the off-chance you’ve only just run across this modest magnum opus, we should perhaps … Read More → "Ultimate Guide to Switch Debounce (Part 9)"

I’ve just been talking to the folks from a jolly interesting company called IOTech. One of the things they told me that really struck a chord was that their technology bridges the OT-IT divide. “But what is the OT-IT divide, and why does it need to be bridged?” I hear you cry. Well, I’m glad … Read More → "IOTech: Bridging the OT-IT Divide"
I can’t believe it; we've finally arrived at the ultimate part of what started out as a mini-series and ended up being a mega-epic. In a moment, we're going to consider FPGA (hardware) and MCU (software) solutions to the switch bounce problem, but first...
I think this is it! I honestly believe this is going to be the last installment in our switch bounce saga. This is where we finally get to consider software solutions to the switch bounce problem (along with a bunch of other topics, of course). Having said this, as usual there are no promises, because -- like you -- I have no idea what is to come until I've written it down.
Way back in the mists of time, when I was bright-eyed and bushy-tailed, as I penned the first words in this quest to explore the topic of switch bounce and debounce, I actually thought it would take only one, perhaps two, columns. Sad to relate, as the days grew into weeks and the weeks grew into months, I grew into a much sadder and wiser man.
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).

Could life evolve on ice worlds, ocean worlds, ocean worlds covered in ice, halo worlds that are tidally locked with their sun, and rogue worlds without a sun? If so, what sort of life might it be?...

I get pleasure from good quality things. Quality is a vague term, but, to me, it is some combination of good design for usability, functionality and aesthetics, along with reliability and durability. Some of these factors can be assessed very quickly; others take time. For ex...

[From the last episode: We looked at the complexities of cache in a multicore processor.] OK, time for a breather and for some review. We've taken quite the tour of computing, both in an IoT device (or even a laptop) and in the cloud. Here are some basic things we looked ...
