The circuit presented here is based on LTC3601, a high efficiency, monolithic synchronous buck regulator from Linear Technology. The circuit operates at an input voltage ranging from 4V to 15V, this makes it suitable for a wide range of power supply applications. It is capable of...

Alex the Giant @ sparkfun.com has a tutorial on how to build smart and connected water sensor using ESP32. He writes: For this project, you can use either the ESP8266 Thing, or the ESP32 Thing. One of the many improvements made on the ESP32 is the capacitive touch circuitry built in...

The MS2760A is the latest release in the Ultra-portable family of USB driven instruments - it can perform spectrum measurements from 9kHz to 110GHz in the industries smallest and lightest form factor. by Clemens Valens @ elektormagazine.com: There was a time, and not so long ago,...

At this year’s Sensor+Test 2017 in Nuremberg (May 30 – June 1), Sensirion AG, the expert in environmental and flow sensor solutions, introduces the SGP - the first and only long-term stable metal-oxide gas sensor. The SGP gas sensor is based on Sensirion’s multi-pixel platform,...

ThePiLocator is a website aims to help you check the availability of pi zero and pi zero w on various online stores. thepilocator.com - check the availability of Raspberry Pi -...

The LT8315 is a high voltage monolithic flyback regulator that simplifies the design of an isolated DC/DC converter. By sampling the reflected isolated output voltage across the third winding on the power transformer, the part requires no opto-isolator or LT1431 for regulation. The...

Orlando Hoilett has built his new biomedical Arduino 101 shield: Biomed Shield, in order to allow students, educators, and hobbyists to learn about bio-medicine by monitoring heart rate, temperature, and other physiological metrics. To build this shield he used the following...

limpkin @ limpkin.fr tries out the CDM324 / IPM165 Doppler effect sensor and proposes an amplification circuit to get the readings out of the sensor. He writes: You may recall the article I wrote a couple of years ago about a nearly identical Doppler sensor, the HB100. While the...
