Elecrow hit Kickstarter with an electronics learning lab-in-a-box based around the Raspberry Pi. A 2nd generation crammed the lab into a laptop form factor. The CrowPi 3 "playground for programming, ...

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

This project demonstrates how to build a simple yet effective Smart Blind Stick using an Arduino and an ultrasonic sensor. The system provides buzzer and LED alerts that vary their rate based on the ...

Without any delays, here are the best Phones with Ultrasonic Fingerprint Sensors (June 2025) that make the cut: ...

After this tedious step, he designed a PCB that hosts an Arduino Nano to accept input, two MCP23017 GPIO expanders to give it enough outputs, and CD4066BE CMOS switches to trigger the connections.

Abstract: Usually movement of goods from one location to another requires human input. This is a tiring job in industries where goods are picked and placed in bulk and the weight of goods to be ...

Recently, many attempts by researchers from different fields have been done to develop sensors that have high accuracy and do not cause any damages to the cells. Here a nano-needle microfluidic system ...

Magnetic nanomaterials (MNMs) have gained great interest from different fields of study ranging from wastewater treatment to (bio)sensor development, taking advantage of both nanoscale size (allowing ...

We propose a micro-ultrasonic diagnosis using an all-optical ultrasound-based spectral sensing (AOUSS) technique for sensitive and quantitative characterization of early stage and whole blood ...
