Wio Terminal: Arduino Smart Doorbell

“Turn your Wio Terminal into a doorbell with automatic motion detection and remote notification capabilities! This project builds a doorbell that automatically detects the presence of movement, then notifies you on your mobile phone wherever you are. You can also …

2D Materials capable of forming complex 3D shapes

“University of Texas at Arlington researchers have developed a technique that programs 2D materials to transform into complex 3D shapes. The goal of the work is to create synthetic materials that can mimic how living organisms expand and contract soft …

3D-printed bioresorbable airway stent

“An ETH Zurich research team is using 3D printing to produce a new type of bioresorbable airway stent. This could greatly simplify the future treatment of upper airway obstruction. Narrowing of the trachea or the main bronchi due to injury …

42V Input – 3.3V @ 2A Output High Voltage Step Down Regulator

“The project described here is a high voltage step-down regulator based on A4447 general-purpose buck converter chip from Allegro Semiconductor. The output voltage of the board is configured at 3.3V, but it is adjustable from 0.8 to 24V …

A language learning system that pays attention — more efficiently than ever before

“MIT researchers’ new hardware and software system streamlines state-of-the-art sentence analysis. Human language can be inefficient. Some words are vital. Others, expendable. Reread the first sentence of this story. Just two words, “language” and “inefficient,” convey almost the entire meaning …

A New Modifier Increases the Efficiency of Perovskite Solar Cells

“The research team of NUST MISIS has presented an improved structure of perovskite solar cells. Scientists have modified perovskite-based solar cells using MXenes — thin two-dimensional titanium carbides with high electrical conductivity. The MXenes-based modified cells showed superior performance, with power …

Adding Cellular to the Raspberry Pi Pico

“Learn how to add a Cellular IoT device to the Raspberry Pi Pico. I, like most of the maker world, was caught totally by surprise last week when the Raspberry Pi team announced their first microcontroller, the Pico. A custom …

Advanced Silicone Mold Making Techniques for Epoxy Casting

“In our last instructable with Phillip, we went over the basics for making simple silicone molds in a home workshop with as few specialty tools and supplies as possible. We’re stepping up our game and introducing some more advanced …

AEgIS on track to test free-fall of antimatter

“The AEgIS collaboration at CERN’s Antiproton Decelerator (AD) has reported a milestone in its bid to measure the gravitational free-fall of antimatter – a fundamental test of the weak equivalence principle. Using a series of techniques developed in 2018, the …

Android Auto on Volvo RTI

“This projects is a addon for my CAN bus extension project in order to add Android Auto functionality. The screen is displaying openauto on the stock Volvo RTI display using a Raspberry Pi and can be controlled using the stock …
