IntroductionIn this post, Post 2, I describe an instrument testing framework. Whilst creating that framework, I wanted to be able to unit test (regression test) parts of it as I progressed - there was a degree of complexity that I needed to ens...
Most humans living on Earth have experienced the dramatic turn of events that the year 2020 brought. We all have been affected somehow by the Covid-19 pandemic. We are 3 months away from the end of the year 2020, and no definitive solution has ...

Hayabusa2 deployed three rovers and a lander on the Ryugu asteroid, which collected samples of the asteroid's surface. The return mission has been officially approved to land in Australia on December 6th. (Image Credit: JAXA/Akihiro Ikeshita)&nbs...
The TI-125 is designed for measurement, detection, and sampling tasks for R&D and industrial functions, but can also be utilized for COVID-19 applications as well. (Image credit: Omega) Omega designed its T-120 Series of thermal imaging came...
'This physical property can be used to make more precise measurements, which in turn can lead to advance technology like quantum computers. Quantum laser light shines on to a chemical molecule that needs to be measured. The light then passes thro...
The new system would be ideal for underwater data centers that need to connect with surface networks. The system uses various off-the-shelf components and a Raspberry Pi to act as a modem. (Image credit: KAUST) With Wi-Fi readily available in ou...
The new method of tracking space junk involves using high-powered lasers that detect diffused reflections bouncing back from the debris orbiting up to 36,000 kilometers away. (Image credit: NASA) There’s a good chance that no matter where you a...
Citizen-owned seismometers showed significant reductions of noise around schools and universities in places like Cornwall, UK and Boston, U.S. (Image Credit: Imperial College London) Seismometers measure seismic waves from earthquakes, vol...
IntroductionThis short blog post documents a simple project to measure current in devices that may have low power operation for periods, but possibly have periods of high current draw.I recently needed to monitor the current of a few wireless devices...
I have a ST Micro Nucleo board with a low power microcontroller. The STM32F030R8I'm going to measure its power consumption, to see how well it would do in low power designs.ST has a good power measurement example; called PWR_CurrentConsumption. I...
