  The EC-Eye has a similar structure and size to a human eyeball, and it has similar capabilities. (Image Credit: Yaying Xu, (c) oFantastic Color Animation Technology Co.)   Researchers from the Honk Kong University of Science and Technology have developed an electrochemical artificial eye, called EC-Eye, which closely resembles a human eyeball’s size and structure with similar capabilities.  EC-Eye could one day provide vision for humanoid robots or function as a bionic e ...
Researchers use new gel-based solution to change taste perception. The gel solution is applied to an electronic device the user presses to their tongue. (Image credit: Meiji University)   When it comes to satisfying cravings, we don’t make the best choices. It’s hard to limit yourself to one cookie if you have a massive sweet tooth. Recent Human-Computer Interaction (HCI) studies have experimented with the idea of Augmented Gustation, altering the taste of food and drinks wit ...
Researchers used the DeepMind Lab to compare how children and AI agents learn about the world. (Image Credit: DeepMind)   Researchers from Alphabet’s DeepMind and the University of California, Berkeley, have proposed a framework to compare how children and AI agents learn about the world via exploration behavior. The team’s work could narrow the gap between artificial intelligence and humans when they’ve learned new skills. For example, it could lead to the development of ...
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 of scientists from the University of Science and Technology in China, National Taiwan University, and Dartmouth College thinks they can make them even better. They created ThreadSense, a smart thread that’s able to locate up to two con ...
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 the load circuit.   That voltage (always negative, because the resistor is "below" the circuit's analog ground) is amplified by a non-inverting OpAmp circuit, with gain 7.8.   Test Setup  A DMM measures the voltage of 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 dozens of different ways to solder though. I have a reflow oven, but it is overkill for a single IC. I have a pre-heater and a hot air tool but the ones I have are under-powered.    Although I have seen an expert present drag solderin ...
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 that is fitted onto a subject as they sleep. It lets researchers communicate with the subjects as they slip into hypnagogia. This device, called Dormio, tracks heart rate, muscle tone, and skin conductance. It even notifies researchers when the s ...
