https://www.electronics-lab.com/5v-12v-inverting-switching-regulator/
The DC/DC inverting switching regulators project is specifically designed to invert input voltages to negative outputs. It offer input voltage ranges from 4.5V to 6V and output -12V 100mA The MC34063A IC is heart of the project from On semiconductor. The MC33063A is a monolithic control circuit containing the primary functions required for DC-DC converters, […]
42V, 3.5A-out buck regulator operates at 175°C ambient
https://www.electronics-lab.com/42v-3-5a-buck-regulator-operates-175c-ambient/
LT8610AX is a 3.5A, 42V input-capable synchronous step-down switching regulator, which operates in ambient temperatures up to 175°C. Synchronous rectification delivers efficiency as high as 95% while Burst Mode operation keeps quiescent current under 3.5 µA in no-load standby conditions. The device’s 3.7V to 42V input voltage range is suitable for high temperature applications such […]
LED current regulator has low dropout
https://www.electronics-lab.com/led-current-regulator-low-dropout/
Peter Demchenko @ edn.com This Design Idea circuit regulates the current through one or more LEDs, making it almost independent of supply voltage. Its main advantage is a very small dropout voltage, which can be less than 100mV. The design could find use on LED strips, where the voltage can vary along the length due […]
Use a Fingerprint sensor module to add biometric security to your Arduino projects
https://www.electronics-lab.com/use-fingerprint-sensor-module-add-biometric-security-arduino-projects/
educ8s.tv has a new video on how to use a fingertip sensor with Arduino. If you want to add biometric security features to your Arduino projects, an easy way to do so, is to add a fingerprint sensor module to it. In this video we demonstrate how easy to use a fingerprint sensor with an […]
Battery-pack fuel gauge with SHA-256 authentication prevents pack cloning
https://www.electronics-lab.com/battery-pack-fuel-gauge-sha-256-authentication-prevents-pack-cloning/
Implementing pack-side battery gauges in portable devices is easier and more secure, Maxim asserts, with its ModelGauge m5 portfolio of MAX17201/MAX17205 and MAX17211/MAX17215. Fuel gauging can be difficult because battery voltage varies with temperature and load, while coulomb-counting requires sophisticated compensation to eliminate offset accumulation errors. Maxim’s ModelGauge m5 fuel gauges include a sophisticated algorithm […]
How to Improve Buck Converter Light Load Efficiency with an LDO
https://www.electronics-lab.com/improve-buck-converter-light-load-efficiency-ldo/
By Michael Hartshorne @ digikey.com: Designing a DC/DC converter that only consumes micro amps of current at no load can be compared to fueling a muscle car with lighter fluid – you may get it to work, but it won’t be easy. High efficiency at full load currents is commonplace in most modern DC/DC converters; […]

Arduino Lightning Detector
https://www.electronics-lab.com/arduino-lightning-detector/
This is an Arduino tutorial on how to detect lightning from far away. In this tutorial, we will build a lightning detector using an Arduino Uno, a few resistors and some jumper wires. Most lightning detectors often cost too much for the normal hobbyist, however this does not mean one cannot enjoy lightning detection and […]
AutoResetRRR – Automatically reset routers/cameras/servers
https://www.electronics-lab.com/autoresetrrr-automatically-reset-routerscamerasservers/
“bogdan” published a new project, a device able to automatically reset your router, camera or server. AutoResetRRR is a kind electronic frustration reducing device: it cuts the power periodically to devices that can go nuts (routers, net cams, servers), but it does give a heads up. If all is well, they can shut down safely […]
