Constant Current Laser Diode Driver Circuit Using OPA2350 OpAmp
https://www.electronics-lab.com/constant-current-laser-diode-driver-circuit-using-opa2350-opamp/
The voltage-controlled current source circuit can be used to drive a constant current into a signal or pump laser diode. This simple linear driver provides a cleaner drive current into a laser diode than switching PWM drivers. The basic circuit is that of a Howland current pump with a current booster (Q1) on the output […]

How to Set Up an Ultrasonic Range Finder on an Arduino
https://www.electronics-lab.com/set-ultrasonic-range-finder-arduino/
circuitbasics.com has a new tutorial on how to measure distance using Arduino and an ultrasonic sensor. Ultrasonic range finders are fun little modules that measure distance. You can use them to find the precise distance to an object, or also just to detect when something is within range of the sensor (like a motion detector). Ultrasonic […]

mcuoneclipse.com writes: To my surprise, when I visited a nearby IKEA store yesterday, the older iPhone and Samsung Galaxy S4 (VITAHULT) Qi receivers were on sale for CHF 0.95 (about US$1): what could be wrong with buying a few of them? At this point, I should probably mention the ‘rolling eyes’ of my wife😉. The […]

Google had launched Android Things, a new comprehensive IoT platform for building smart devices on top of Android APIs and Google’s own services. Android Things is now available as a developer preview. Android Things was basically launched as an enhancement for Brillo, Android based OS used for embedded development in particular for low-power IoT devices, […]
Circuit Board Design for Beginners
https://www.electronics-lab.com/circuit-board-design-beginners/
By: Alex Danovich,President San Francisco Circuits We live in an exciting time where we see a resurgence in electronics as a hobby. Mass production has wiped out a generation or two of kids learning to build radios from scratch with their mom or dad. In the good old days, not sure when, you had companies […]
