360-degree transparency for construction sites made simple

“Jeevan Kalanithi SM ’07 is CEO of OpenSpace, a company founded by three Media Lab graduates using computer vision to benefit the construction industry. MIT spinoff OpenSpace invented automated 360-degree video jobsite capture and mapping. “It’s not exactly an …

5 W + 5 W Dual BTL Class-D Audio Amplifier

“The project described here is a high-efficiency dual BTL class-D audio amplifier with single supply operations. The project was built using TDA7491LP13TR from ST. The low profile PCB design can fit in a small area, operating power supply 9-12V DC …

50W Power Amplifier with LM3886

“This is my second encounter with LM3886. I was pleased with the sound this chip produced the first time, so I decided to make another amplifier with it. The schematic is based on the schematic in the datasheet of the …

A new approach creates an exceptional single-atom catalyst for water splitting

“Anchoring individual iridium atoms on the surface of a catalytic particle boosted its performance in carrying out a reaction that’s been a bottleneck for sustainable energy production. A new way of anchoring individual iridium atoms to the surface of …

Ambi-Alice a First Order Ambisonic Microphone

“An Ambisonic Microphone records audio in multiple directions allowing you to change the direction of where you are listening after recording, sometimes while you are listening. There are several of these on the market but we are going to build …

An Accidental Discovery Hints at a Hidden Population of Cosmic Objects

“Brown dwarfs aren’t quite stars and aren’t quite planets, and a new study suggests there might be more of them lurking in our galaxy than scientists previously thought. A new study offers a tantalizing explanation for how a …

Are you quantum or not? Wits PhD student cracks the high-dimensional quantum code

“A new and fast tool for quantum computing and communication. Isaac Nape, an emerging South African talent in the study of quantum optics, is part of a crack team of Wits physicists who led an international study that revealed the …

Artificial ultra-tiny ‘hairs’ open up future small-scale applications

“Our researchers have developed a new way to make magnetic artificial so-called cilia comparable in size to real cilia that could be used in future microfluidic devices and sensors. Cilia are tiny hairs used in transport and sensing in the …

Astra rocket fails to reach space during test launch for US military

“The third try wasn’t the charm for Astra. The California Bay Area startup attempted its third orbital test flight today (Aug. 28), sending its two-stage Launch Vehicle 0006 skyward from the Pacific Spaceport Complex on Alaska’s Kodiak Island …

Charging stations can combine hydrogen production and energy storage

“EPFL scientists have developed a new system that addresses two top priorities of the energy transition: clean hydrogen production and large-scale energy storage. Their technology could be particularly useful in transportation applications. The need for reliable renewable energy is growing …
