Accelerometers for vibration measurements & wireless condition monitoring
https://www.electronics-lab.com/accelerometers-vibration-measurements-wireless-condition-monitoring/
Graham Prophet @ eedesignnewseurope.com discuss about two new MEMS accelerometers from Analog Devices: Analog Devices (ADI) has added two devices to its low noise, low drift, low power, three-axis MEMS accelerometers. The low noise performance over high frequencies provided by the ADXL356 and ADXL357 MEMS accelerometers delivers high resolution vibration measurements that enable the early […]
Open Source UV Index Detector

Boris Landoni @ open-electronics.org documents his UV index detector. It measures solar radiation and visualizes the corresponding value on the integrated display of a miniaturized Arduino, in order to tell us when to expose ourselves to the sun… Open Source UV Index Detector – [Link]
SEPIC/Ćuk converter sprouts second output
https://www.electronics-lab.com/sepiccuk-converter-sprouts-second-output/
by Gheorghe Plasoianu @ edn.com Many applications require positive and negative supply voltages, with only one voltage requiring tight regulation. This Design Idea describes a dual-output, hybrid SEPIC–Ćuk converter whose positive output voltage can be lesser or greater than the input voltage. The unregulated negative output is a mirrored replica of the positive output. SEPIC/Ćuk […]
Reverse engineering the 76477 sound effect chip
https://www.electronics-lab.com/reverse-engineering-76477-sound-effect-chip/
Ken Shirriff has written an article on reverse engineering the 76477 “Space Invaders” sound effect chip: Remember the old video game Space Invaders? Some of its sound effects were provided by a chip called the 76477 Complex Sound Generation chip. While the sound effects1 produced by this 1978 chip seem primitive today, it was used […]

by Graham Prophet @ eedesignnewseurope.com: Lattice Semiconductor positions its Embedded Vision Development Kit as the first of its type, that is optimized for mobile-influenced system designs that require flexible, low cost, and low power image processing architectures, by which the company refers to Robotics, Drones, ADAS, smart surveillance and AR/VR systems Embedded vision development kit […]
Printed Two-Dimensional Transistors
https://www.electronics-lab.com/printed-two-dimensional-transistors/
Researchers from AMBER (Advanced Materials and BioEngineering Research) and Trinity College (Dublin), together with the TU Delft have succeeded in producing printed transistors, which are made solely from two-dimensional nano materials. These materials have characteristics with much promise and, importantly, can also be produced very cheaply. Possible applications for this procedure are food packaging with […]
Zephyr Project Hosted by Linux Foundation — Yet Another RTOS for IoT
https://www.electronics-lab.com/zephyr-project-hosted-linux-foundation-yet-another-rtos-iot/
What is Zephyr? Zephyr is a small footprint IoT RTOS (less than 10kB) with no user-space and dynamic allocation which make it suitable to run on resource-constrained platforms. Moreover, it’s modular and supports multiple architectures, including ARM, X86,ARC, NIOS-II and others). Zephyr is an open source project under Apache 2.0 License and hosted by Linux […]
What Is Household Ground?
https://www.electronics-lab.com/what-is-household-ground/
RimstarOrg published an interesting video on his Youtube channel to demonstrate why In north America you can find 3 holes in the electricity socket; which are hot, neutral and ground. The hot wire goes to a breaker-panel and then to electricity grid and finally to a transformer somewhere. While the neutral line is connected with […]
