I've been running a roadtest called AVNET Monarch LTE-M Development Kit -- EU   This dev kit is a cellular IoT kit featuring the NXP LPC55S69-EVK and the Monarch Go Arduino Shield. It's well-suited for LTE IoT application development.   I opened the roadtest to U.S. members only because it comes with a Verizon ThingSpace IoT SIM card. (Verizon is a U.S. based mobile operator.)   At the point in time, I have only a handful of applicants.   If you are a U.S. member, and ...
After completing the Multicomp Pro Non-Contact Voltage Tester - Review, I asked myself "Why don't I use this type of tool more?"  Then I started thinking of some of the events that distracted me along the way.  This blog just might be my version of the bloopers reel.   Does a good ground really matter? I know it does, but how much?  I call this the Flamingo Testing Method.  Stand on the sneaker.  Measure.  Stand on the bare foot.  Measure.  Hope Amazo ...
Early last year, element14 published a spotlight article ( Are You Ready To Use an IoT Enabled Power Circuit Breaker? ) on an interesting product by Eaton called the Power Defense Circuit Breaker. In the article, we said it was an IOT-enabled CB because it not only provides the typical functions of a molded case circuit breaker, it also has the ability of connecting to the Internet in order to report on "breaker health" or can be customized to transmit a variety of sensor data to the cloud. Give ...
To a man with a hammer, everything looks a nail.          To a man with a non-contact voltage tester... anything energized needs to be checked. As part of roadtesting the Multicomp Pro Non-Contact Voltage Tester, I couldn't resist trying it out in a few non-roadtest applications.  Here is one.     Yes.  The string is repaired, ready for next year. ...
Part 4 of R&S NGP814 Power Supply - Review   This part of the review focuses on transient behaviour, the Rigol DL3021 electronic load is used to generate the various load conditions used in the experiments. The table below is from the NGP814 datasheet, the T90 rise time value is below 10ms.     To get a feel of the rise time over the rated power range the following tests were done using Channel 1 at various percentages of the rated power (200W). [Note: all measurements ...

Introduction I designed and built 2 projects to go along with the RoadTest of the Eaton easyE4 PLC. These go with the RoadTest, but are extra information. I will try and keep my opinion to the review. All pages are likely to be updated as I get to grips with adding information. (I can already see the screen grabs of the ladder diagram have lost some resolution and will try again) I tried to keep everything fairly basic as I was trying to test the PLC and the software that went along with it. ...

I will try and keep my opinion to the review. All pages are likely to be updated as I get to grips with adding information. I tried to keep everything fairly basic as I was trying to test the PLC and the software that went along with it. As such I also tried to keep the voltage down to 12Vdc. A lot of what I ended up using (Arduino/Ras Pi) ...
