The small brain implant is slid deep into the folds of the brain and is used to gradually restore muscle control and sensation functionality for paralyzed patients. (Image credit: Feinstein Institutes for Medical Research)   Scientists from the Feinstein Institutes for Medical Research have developed brain implant electrodes to provide muscle control and a regained sense of touch for patients paralyzed from brain and spinal injuries. In a pair of recently released scientific papers, the sc ...
The new telescope will explore 17 forming planetary systems and measure spectra to identify molecules in the inner regions of protoplanetary discs. (Image credit: NASA)   NASA is furthering its exploration mission with the upcoming launch of the James Webb Telescope, the successor to the Hubble. Slated to launch on December 8, 2020, the telescope will be located near the second Lagrange point (between two bodies in orbit) of the Earth/Sun system, which is approximately 900,000 miles from ...
I recently bought a QUICK 191AD soldering iron thermometer, here's a 3-minute review : )   This instrument costs about £100 in the UK (a couple of resellers in the UK stock it). It comes with a pack of ten sensors, there is a spring peg to hold it taut. It's a type-K thermocouple basically. I cannot say it is the most useful tool in the world, I'm unlikely to use it often just to check soldering iron tip temperature. I may get a bit more use out of the tool simply because it has ...
The clock uses lasers to cool strontium atoms to billionths of a degree above absolute zero and traps them in optical lattices. (Image credit: Pixabay)   Hidetoshi Yatori (University of Tokyo/RIKEN) and Jun Ye (UC Boulder/NIST) have won the 2022 Breakthrough Prize in Fundamental Physics for their contributions to the invention and development of optical lattice clocks that enable precision testing of fundamental physics. The Breakthrough Prize is like the “Oscars of Science” an ...
This ultra-short blog post is just a quick follow-up to the measurement amplifier project Viewing Noise with a Measurement Amplifier  which basically describes a X100 or X200 gain amplifier for working with sensors or measuring noise on power rails. The amplifier is fully described in the earlier blog post, but at that time I had not finished assembling it into the enclosure. The video here shows the completed amplifier in use:     The oscilloscope capture in the photo below s ...
Introduction What's a VNA, and What's "Calibration" in this Context? What can the DIY tool do, and what can't it do? RF Switching Unit OSL Board Assembling the Boards Using the Device Example Scenario #1: Inductor and Resistor in Series Example Scenario #2: Amplifier Input Port Measurement Summary   Introduction This blog post describes a DIY tool for VNAs that can allow users to get going with easily attaching components or circuits to the VNA and ge ...
Researchers developed a camera that captures images at a trillion frames per second using a streak camera and a laser that generates light pulses. (Image Credit: M. Scott Brauer/MIT)   In 2011, MIT scientists developed a camera capable of capturing images at a trillion frames per second. Accomplishing such a feat allowed the team to obtain video footage of light traveling 600 million miles per hour in a one-liter bottle filled with water. It only took a nanosecond for the event to transpir ...
Introduction 1. Save the Data 2. Transfer the Data to the PC 3. Export the Data in CSV Format 4. Convert to .s1p Touchstone Format Example: Viewing using Python scikit-rf Summary   Introduction When working with the FPC1500 in Vector Network Analyzer (VNA) mode, it can be handy to transfer the captured data into math programs and other PC software. Fortunately, that's very easy to do; there is an in-built file system and data can be transferred across easily. I ...
