Home News Ultra sonic distance finder with live status By Emanuele Signoretta on August 27, 2022 Hello everyone, This is a simple yet great and super easy project. In this project, we are using one ultrasonic sensor to track one…

Make a dual power bank 1A/2.1A using 18650 Li-ion cells.

About the power bank circuit In this project, we will be making a power bank using a pre-built power bank circuit and 18650 Li-ion cells. This power bank circuit has an onboard LCD that will show you the total charge…

What is Turnkey PCB Assembly

Most entrepreneurs and manufacturers find out that the old method of manufacturing electronic products and printed circuit board components is daunting because it is slow, error-prone and expensive. It is not designed for small batch runs and prototyping, or to…

New Optoelectronic Functionalities using Large-scale Computations

Assembling Lego-like, 2D heterostructures can give rise to emergent properties and functionalities very different from the intrinsic characteristics of the constituents. Density functional theory (DFT)-based band-structure calculations can shed light on interfacial properties of different heterostructures. Interface properties of 2D…

Ameliorating Image Sensors for Machine Vision

Image sensors measure light intensity, but the angle, spectrum, and other aspects of light must also be extracted to significantly advance machine vision. the University of Wisconsin-Madison, Washington University in St. Louis, and OmniVision Technologies highlight the latest nanostructured components…
