Introduction This is the next instalment in my insulation tester review series, in a bid to find a more suitable tester for the type of work that I do. The previous testers reviewed are; Keysight Insulation Multimeter FailureMegger MI...
I'm designing a low power IoT in the Cloud framework for the Arduino MKR WIFI series. A firmware proof of concept that uses the low power option of this Arduino as much as possible, only to wake up to make a measurement and beam it to Amazon Web Serv...
www.youtube.com/watch A team from Northwestern University has created a body sensor to help monitor babies in neonatal intensive care units (NiCU). The sensors are wireless, soft and flexible and have an advantage due to replacing other sensors ...
IntroductionMy car battery died recently, and I thought I’d try out an Energizer car jump-starter. This was a new product to me – I had not realized that such compact lithium ion jump starters were available! It reduces the need to find someone else’...

IntroductionFor years I’ve been “helping hand”-less. Since I was a kid, the design of the classic helping hands has not really changed - it has stood the test of time, but just for lightweight tasks. For anything large/heavy, it all goes wrong. ...
Pt100 Sensors for Industrial Use The use of a platinum resistance thermometer probe in industrial and scientific applications will normally result in good, accurate temperature sensing without the need for special cables (unlike thermocouples). ...
Now that I have a programmable psu, dc load, oscilloscope and multimeter, it's time to build a flexible test bed.It's main purpose is to specify efficiency of switch mode regulators. But with some tweeking itcan also be used to measure ripple...
www.youtube.com/watch Advances in electron microscopy have given a much deeper insight into the nanoscale world. Experiments using electron microscopy only has a small amount of information generated as the beam hits the samples. A team at the D...
Late last week at work, our head of Maintenance at work had an older Fluke 190 Scopemeter at his desk. He said that something was wrong with it and he wasn't sure what to do with it - send it in for repair, or get rid of it and get a new one. At almo...
Advances in a nanomaterial-based detector platform arrive thanks in large part to Mahmooda Sultana's fund winnings. The $2 million award comes from NASA's Goodard Space Flight Center and will take two years to advance the multifunctional sens...
Introduction Continuing with my insulation tester series, I have changed the rules for this review slightly. Whilst the earlier reviews showed different offerings from manufacturers, this one will be a review of two very similar meters, detailin...
Cruising in Siberia's Lake Baikal. (Image via pixabay) The magnetic north pole is rapidly moving away, and scientists can't explain why. It's been occurring in the past few decades, and the effect makes estimates for navigation a bit...
I'm road testing the Keithley Bench Digital Multimeter DMM6500.In this post, a simple method to save measurements and list them in a table with a keypress. Saving Measurements to a Table This is the default behaviour of the DMM....
One of the things that jump out in Louis Rossmann's videos is the type of flux he uses (and the amount ).The fluxes I have at home are liquid, and that works well when building new PCBs. The Amtech flux I'm testing here is a jelly when applied and be...
A city that was completely lost to time in the outskirts of Johannesburg, South Africa has been re-discovered. The ancient stone huts that can be seen from the naked eye was actually an active city that had been lost for 200 years. Archaeologists in ...
I'm road testing the Keithley Bench Digital Multimeter DMM6500.I proposed in my application to focus my review on instrument automation.In this post I review Keithley Communicator, an application to directly send TSP and SCPI commands to the me...
I'm road testing the Keithley Bench Digital Multimeter DMM6500.In this post, I investigate how to use the external trigger to start a measurement.In this post, everything is configured and executed in LabVIEW. In the previous post I used the fr...
I'm road testing the Keithley Bench Digital Multimeter DMM6500.In this post, I investigate how to use the external trigger to start a measurement.In this post, the setup is manual. In the next post I'll use LabVIEW to automate the process. ...
I'm road testing the Keithley Bench Digital Multimeter DMM6500.In this blog, I presents a script that measures a microcontoller power consumption using an EEVblog µCurrent.Knowing the amp hours your application consumes, helps to predict batter...
I'm road testing the Keithley Bench Digital Multimeter DMM6500.In this blog, I verify the performance of an EEVBlog µCurrent via LabVIEW.Note: this is not a real validation of the µCurrent . This is a showcase on how a DMM6500 can be used in su...
I'm road testing the Keithley Bench Digital Multimeter DMM6500.In this blog, I verify the performance of an EEVBlog µCurrent; from the DMM6500 frontpanel controls.. The µCurrent is a test instrument that translates current to vol...
Start-up company, Spryng has released its latest device, Spryng, to help with those tired, achy legs after a workout. (Image Credit: Spryng) Exercise buffs, hikers, gamers, travelers, partiers and people who have sat at the desk for too long all...
I'm road testing the Keithley Bench Digital Multimeter DMM6500.The instrument can run apps, and you can roll your own (what a great time do be alive ).In this blog, I'll show how you can show images on the display. Why, Jan? App...
