TeamVenture-Bit tipped us with their kickstarter campaign. It’s about a closed loop motor upgrade kit that will enable your 3D printer to print faster, silently and more consistently. Check it out. Boasting an advanced PID compensation system that detects issues while your 3D printer or other CNC based machine is moving, Wembi readjusts itself to […]

Wide range of Hygrometers Compared


https://www.electronics-lab.com/wide-range-hygrometers-compared/

robert @ kandrsmith.org has a detailed article comparing the most common Humidity sensors. He writes: Previous experiments looked at comparing a set of six Aosong DHT22/AM2302 and compared the Aosong DHT22/AM2302 with the Aosong DHT11 and Sensirion SHT71. Here I have added five new devices meaning this test now covers most commonly available low-cost digital […]

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 […]

DIY IKEA Wireless Qi Charging

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 […]
