Keysight MXA revision-b signal analyzer / Spectrum analyzer review, analysis & experiments from The Signal Path: In this episode Shahriar reviews the long awaited Keysight MXA Signal Analyzer (N9020B). The new X-Series Spectrum Analyzers from Keysight offer an entirely...

Seismic activity or "Vibrations of the earth" is measured using ProtoCentral's OpenPressure 24-bit DAQ System. A geophone is a magnetic device used to measure the Earth's normal vibrations (some abnormal during events such as earthquakes). These movements are also present when there...

Engineers at the University of Bristol have developed a three terminal pico-power chip that can cut standby drain in sensor nodes – even compared with today’s low-power microcontrollers. It does this by replacing the low duty-cycle sleep-wake-sleep pattern used on MCU-based sensor...

pinko @ exrockets.com has published a mini barometric altimeter based on PIC18F2553. He writes: I found on Ebay very nice, small 12v 23A battery holders for PCB mounting style and decided to fit the SMALL DIGITAL BAROMETRIC ALTIMETER just on the back of the holder. So basically...

Radiation is always present in our lives. We can't see, taste, feel or smell it, but it exists. Excessive exposure to ionizing radiation may cause potential damage to our health. The new Dosime device helps you to track and understand radiation exposure in your environment and display...

Stoneslice has shared a Curve Tracer tutorial on Youtube that uses an X Y mode Oscilloscope to test components and their characteristics. Using the on-board Phase Shift Oscillator to provide the test signal, passive and active parts can be tested. These are the  components needed to...

"pinko" build a laser trigger for chronograph using PIC18F2550 and LM393 comparators. He writes: I finished this laser wall trigger for my HIGH RESOLUTION AND ACCURACY CHRONOGRAPH. The purpose of this device is to generate the trigger start and stop impulses for my chronograph as...

Silicon Lab’s TS1100 and TS1101 current sense amplifier’s features discussed in this app note. Sensing and controlling supply current flow are a fundamental requirement in most all electronic systems from battery-operated, portable equipment to mobile or fixed-platform power...
