(Image credit: Anthony Quintano via Wikipedia)   2018 is coming to a close in a few hours, with the start of the new year being ushered in by party-goers everywhere. One of the most populated areas for celebrating the New Year is in Times Square, where thousands have gathered since 1907 to watch the famous ball drop. As you could imagine, security is a big concern for the event, and the NYPD will be out in force to make sure nobody gets hurt during the festivities. While the police have mu ...
The bandages use pulses from the body and could only take days instead of weeks to heal wounds Electrical bandages could help to speed up the timeline for recovery. (Image Credit: Sam Million-Weaver/University of Wisconsin-Madison)   Newly developed self-powered electrical bandages designed by researchers from the US and China promise to be just as easy to wear as dressings.  These new dressings have tiny electrodes powered by nanogenerators wrapped around the torso.  The only th ...
The researchers used a technique known as ‘implosion fabrication’ to shrink objects to nanoscale. (Image credit: MIT)   Researchers from MIT have developed a way to shrink complex 3D objects down to nanoscale sizes using hydrogel and a laser. Using a new technique known as ‘implosion fabrication,’ the researchers are able to create any 3D structure they want by using a laser to pattern a polymer scaffold. They can then attach hydrogel to the structure to shrink it d ...
A Brazilian research team invented a wheel chair that the user can operate using his/her facial expressions. (Images from HooBox.com)   Last year, Apple surprised the world with a new generation of iPhones that use facial recognition; and even though it is a first in the cellphone industry, facial recognition is not really new. Just like fingerprints, facial recognition is a biometric feature. Software and devices have sensed facial characteristics and compares them to stored data to ident ...

Mestek Multimeter

Posted by mp2100 Dec 14, 2018
This item arrived on my desk today (thanks Terry).  Mestek model CM81, Digital Clamp Meter.  It's inexpensive, available on Amazon.  It's made in China, Shenzen.   It's Cat III, 600volts.  It has a lot of features.  I have two low end Fluke meters, and I wanted a clamp-on amp meter for when I'm troubleshooting control panels. The user manual is short, but then, the manual that came with my Fluke 115 had less information.  It comes with basic test leads, wi ...
A team at Imperial College London and M Squared have built a new navigation device using a quantum accelerometer. The large device is made with ships and trains in mind. (Photo via Imperial College London)   GPS is essential for navigation and since it’s a standard feature on all smartphones, getting lost is no longer a worry. Unfortunately, it’s not always reliable. All it takes is a failed satellite or a jamming attack to make GPS useless. Now, scientists believe they have fo ...
BrainGate2 is an electrode system implanted in the brain that lets you text, send emails, and browse the internet with your mind. Two people send text messages using BrainGate2. (Photo via BrainGate)   Imagine being able to fire off a text message with your mind. A new electrode system called BrainGate2 does exactly that. A new study found that three people paralyzed from the neck down were able to use unmodified tablets to send text messages, browse the internet, and stream music using th ...
