Laser Beam Wireless Smartphone Chargers: The Next Big Thing
https://www.electronics-lab.com/laser-beam-wireless-smartphone-chargers-next-big-thing/
Cellphone chargers have been in existence for years and have grown from one stage to another. It started with the mobile phone traditional charger which had a USB interface, a DC converter, and a charging plug and now has expanded to a close-range inductive wireless charging. The commonly used inductive wireless charging is nice but […]
IBM just unveiled the ‘world’s smallest computer’
https://www.electronics-lab.com/ibm-just-unveiled-worlds-smallest-computer/
by Paul Miller @ theverge.com The computer is 1mm x 1mm, smaller than a grain of fancy salt, and apparently costs less than ten cents to manufacture. To be clear, the picture above is a set of 64 motherboards, each of which hold two of this tiny computer. IBM claims the computer has the power […]

Introducing Project Fin, a carrier board designed for the Raspberry Pi Compute Module 3 Lite. It’s a carrier board that can run all the software that the Raspberry Pi can run, hardened for field deployment use cases, and adding some of the things we’ve seen our users needing the most. It includes 8/16/32/64 GB of […]
Powering Batteries With Protons – A Potential Disruption in the Energy Industry
https://www.electronics-lab.com/powering-batteries-protons-potential-disruption-energy-industry/
Climate Change have been a crucial factor taken into consideration by the Australian researchers from Royal Melbourne Institute of Technology before creating the first rechargeable proton battery. After considering all available options about cost and availability of the materials needed, the researchers in Melbourne decided to make a proton battery to meet up with the […]
Program Pi, BeagleBone and Other Linux SBCs On The Arduino Create Platform
https://www.electronics-lab.com/now-can-program-pi-beaglebone-linux-sbcs-arduino-create-platform/
We have seen the massive ecosystem the Arduino has built and established over the last few years and this has made developing with Arduino quite leisurely. It is way easier to solve a programming issue or hardware issue with Arduino unlike other hardware boards mostly due to its community. Arduino Create is an online platform by the […]
How to make precision measurements on a nanopower budget
https://www.electronics-lab.com/make-precision-measurements-nanopower-budget/
Gen Vansteeg @ ti.com discuss about precision measurement for nanopower scale using OPAMPs. Heightened accuracy and speed in an operational amplifier (op amp) has a direct relationship with the magnitude of its power consumption. Decreasing the current consumption decreases the gain bandwidth; conversely, decreasing the offset voltage increases the current consumption. Many such interactions between […]
HDC2010 – Low Power Humidity and Temperature Sensor
https://www.electronics-lab.com/hdc2010-low-power-humidity-temperature-sensor/
The HDC2010 is an integrated humidity and temperature sensor that provides high accuracy measurements with very low power consumption, in an ultra-compact WLCSP (Wafer Level Chip Scale Package). The sensing element of the HDC2010 is placed on the bottom part of the device, which makes the HDC2010 more robust against dirt, dust, and other environmental […]
USB Adaptive Charger (2.7A per port) with Wattmeter
https://www.electronics-lab.com/usb-adaptive-charger-2-7a-per-port-wattmeter/
A 10.8A, 4 port USB charger with a wattmeter and adaptive intelligent charging. It works by taking any DC input between 7V to 17V, from an AC/DC adapter or car adapter. It can be used anywhere with wall outlets, car power ports, lead-acid batteries, DC-output solar panels, and lithium-ion battery packs (2S, 3S, and 4S). […]
TPS61092 Boost Converter on Test Bench
https://www.electronics-lab.com/tps61092-boost-converter-test-bench/
luckyresistor.me tests his TPS61092 boost converter with a thermal camera and shares the results. For my current project I searched for a good boost power converter which is able to deliver continuous 400mA power for various sensors. There are an endless number of good boost converters around, but not many can be hand soldered to a […]
MEMS technology shrinks loudspeakers
https://www.electronics-lab.com/mems-technology-shrinks-loudspeakers/
Miniature MEMS-based speakers could revolutionize speech and music reproduction in mobile communication devices. They combine the advantages of a large frequency bandwidth and high acoustic quality with the ability to generate very high sound levels. Nevertheless, they are so tiny that they can be integrated into headphones. By Christoph Hammerschmidt @ eenewseurope.com The breakthrough has […]
