A new prototype from UCLA can translate sign language using a smartphone with 98.63% accuracy. Unlike previous devices, this one is lightweight and inexpensive. (Image credit: UCLA) American Sign Language (ASL) is a difficult language to l...
The diagram shows the conditions that cause the Kohn anomaly to rise in convenient metals (left) and a material is known as a Weyl semimetal (right). (Image Credit: MIT) Researchers at MIT and elsewhere have discovered an exotic physical p...
A small script for the DMM6500 to take a number of measurements, triggered by an external signal.This can be useful when you're automating a test setup. On a production line, on a binning desk, in a setup with a foot pedal, ...I've deliberate...
Organizing wire stock is an important requirement in any lab but there are always costs and compromises. This is yet another attempt to deal with some of my spools of solder and hook-up wire. So far it is a great solution for my solder spools. It wou...
A little bit of nostalgia: my Philips power supply.3 channels. Isolated. Constant voltage and constant current.And perfectly silent - no spinning fan.Made in Belgium!click to enlarge Over here, Philips was the go-to brand for lab instruments.Whe...
The AI-powered eye exam could replace the Snellen eye char in the future. The StAT test has proven to be more accurate. (Image Credit: Gary Cassel/Pixelbay) Classic eye exams are poised to get an upgrade in the future. Researchers from Stanford ...
The KnittedKeyboard prototype was created by using advanced 3D knitting machines. By using this technology, the customized keyboard could be printed in just one hour. (Image Credit: Andreas Eggenberger, MIT Media Lab) Instruments aren’t flexible...
I'm thinking about building a low power SMU.We're playing with OpAmps and discrete semiconductors regularly over here, and there's a Keithley 2450 SMU with I-V Tracer Software road test going on.Learnings from those activities can b...

A team of scientists creates ThreadSense to test their new touch sensing technique. The smart thread can detect touch locations. (Image credit: Dartmouth) Touch sensing technology is becoming more common, and it’s continuously improving. A team ...
Detailed review of the current shunt circuit of the Programmable Electronic Load.The circuit and measurements are discussed here. Circuit The current measurement circuit reads the voltage over a 50 mΩ shunt resistor that's in series with th...
I had to solder an IC today, nothing new there, but usually I'll use a 1mm conventional soldering tip (slice off conical shape) to solder each individual pin one-by-one, deal with any bridges with desoldering braid, and call it a day. There are...
The glove-like device, Dormio, is outfitted with a series of sensors that can determine which sleeping state the wearer is in. (Image Credit: MIT) Researchers from MIT's Dream Lab are in the process of developing an open-source glove-like device...
LabVIEW 2020 Community Edition has just been released (yesterday on the day I type this).I was part of the Beta test team.To celebrate the release, a flow to characterise a lab instrument: use a power supply and a digital meter to validate a DC load....
The sensors are incorporated into narrow channels of the garment, which can be worn to monitor vital signs, like breathing, heart rate, and temperature changes. (Image Credit: MIT) Researchers from MIT have developed a new lightweight sensor tha...
UNI-T multimeters have spread widely in recent years, due to their low cost and characteristics that come closer to the higher-end DMMs. Many models have an interesting feature: the ability to connect to a computer via USB, for data logging. For...
