Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have come up with a way to image polarization out of one snapshot. The tiny, portable camera is the same size as a thumb and can be used in systems of autonomous vehicles, aircraft or even satellites to observe chemistry in the atmosphere, or even be used to detect objects that blend into the background. The team presented their findings in Science.   The polarization camera gives us a glimpse o ...
A friend gave me a couple of Pomona Insulation Piercing Clips which I thought were pretty neat. Apparently they are quite popular with the automotive repair/test crowd. The clips were something I had not seen before, so thought maybe it would be good to share some pics/video if anyone else has not seen these before either.   In brief, they can connect to banana plugs (there is also a version of clip compatible with multimeter test leads) and then the other end can be hooked over an insul ...
The new smart network could drastically change how wearable devices connect to radio waves. These conductive textiles can be integrated into clothing to boost signal up to 1,000 times. (Image credit: NUS)   Wearable technology continues to be a major trend in electronics. From smart watches to smart clothing, developers are finding new ways to integrate technology and the human body. Most wearables are connected to your smartphone and transmit all data via Bluetooth or Wi-Fi signals. The p ...
Neuralink’s HMI uses ‘threads’ that are injected into the brain to tap into neuron activity, which can be read by machines, essentially understanding human thought. (Image credit: Pixabay)   Elon Musk recently unveiled the progress that’s been made with his neurotechnology company Neuralink and their endeavor in developing implantable brain-machine interfaces (BMIs). The company states that they are getting close to fielding human trials next year for their neuron-r ...
By age 45, many people may suffer from an eyesight condition called presbyopia, which causes the lenses to lose elasticity in our eyes. Our vision requires the elasticity to help keep our eyesight focused on nearby objects. There are also some fixes like reading glasses, surgery or progressive lenses that can help to overcome the defect, and as of recent, there’s autofocals. Developed by electrical engineer, Gordon Wetzstein and his team at Stanford University, the prototype glasses are id ...
Scientists from UCLA have discovered a new way to look at nucleation. By using 4D atomic resolution (which is three dimensions of space and time), the team was able to record how atoms rearrange. Their new discovery, which can be found in the journal Nature, offers a different perspective from predictions made on the original theory of nucleation that can be found in textbooks.   Nanoparticles in an iron-platinum alloy changes state three different times. Observations were recorded usin ...
I'm building a GUI for the electronic load we made here on element14. The development will be in a few incremental steps. This is the second iteration: add error logging make the LCD display emulation work a few dedicated controls to set current and enable / disable input   Retrieve Instrument Status: Multiple SCPI Commands Combined  The screen refreshes the GUI controls based on the instrument status. LCD display displays mode, set current, measured current and voltage, inpu ...
The researchers created a neural network system that can decipher text from lost languages. (Image credit: Sharon Mollerus via Wikipedia)   Researchers from MIT’s CSAIL (Computer Science and Artificial Intelligence Laboratory) and Google Brain have developed a neural network that is capable of deciphering dead languages, including Linear B- a syllabic script that was used for writing Mycenaean Greek, the most ancient form of the Greek language. In a recent paper titled “Neural ...
I'm building a GUI for the electronic load we made here on element14. The development will be in a few incremental steps. communication with the instrument basic GUI with a SCPI command line and results In the next iterations: add error logging make the LCD display emulation work a few dedicated controls to set current and enable / disable input   Functionality in the 1st Iteration  The application has its basic layout and one function implemented. I want to start with a lay ...
My electronic load failed. In this second post, I test the remaining parts of the DAC/ADC board.   Tests Approach  The eload DACs and ADCs are on a separate PCB, together with the voltage reference and the I2C isolator. The voltage reference isn't damaged. I've tested that in the previous post.   All DAC outputs and ADC inputs are broken out to the connector at the low side of the board. The load's firmware has low level SCPI functions that can directly talk to the convert ...
Introduction This blog post discusses a project to build a simple logic analyzer (hobby-grade; it samples at up to 24 Msps, good enough for basic debugging when other tools are not available), but it has a few extra features too. This project could be handy for troubleshooting I2C or SPI when working on projects. It can in theory also be used for generating protocol output too, and for operation as a programmer for microcontrollers and FPGAs.   Nearly all digital electronics nowadays has a ...
My electronic load failed. I was trying new hardware and software options. At a certain moment the power MOSFET died. There was no magic smoke, but the source, drain and gate are all shorted (source, drain and gate all measure a few Ohms in both directions). I am not 100% sure of what has happened, but I think that a bad contact at the gate or current sense resistor, while the FET was supplied with 40 V, did it. No sound, no smell. Just an instantaneous death. In this post, I'm checking what ...
