None sequential gear clock

“I was introduced to the idea of a none sequential clock by Bob at Hacman. The idea is two large gear rings with hours and minutes engraved on them driven by stepper motors. The numbers though, are out of sequence …

PIR Motion Sensing with the ATtiny1627 MCU Family

“Sense motion and environmental changes with a passive infrared sensor (PIR) on the ATtiny1627 MCU family. When I was in college, I was friends with one of the lab engineers that managed the electronics labs in the department. One of …

Qualcomm Announces World’s First 10 Gigabit 5G Modem-RF System

“Qualcomm Technologies, Inc. today announced the Snapdragon X65 5G Modem-RF System, its fourth-generation 5G modem-to-antenna solution. It is the world’s first 10 Gigabit 5G and the first 3GPP release 16 modem-RF system, which is currently sampling to …

Quantum computing enables simulations to unravel mysteries of magnetic materials

“A multi-institutional team became the first to generate accurate results from materials science simulations on a quantum computer that can be verified with neutron scattering experiments and other practical techniques. Researchers from the Department of Energy’s Oak Ridge National …

Quantum Computing Scientists Call for Ethical Guidelines

“A group of quantum computing experts, including scientists and company executives, want to raise ethical concerns about the technology’s potential to create new materials for war and accelerate human DNA manipulation. Six experts are featured in a 13-minute video …

Quantum effects help minimise communication flaws

“Noise limits the performance of modern quantum technologies. However, particles traveling in a superposition of paths can bypass noise in communication. A collaboration between the Universities of Hong-Kong, Grenoble and Vienna, as well as the Austrian Academy of Sciences, under …

Radiative cooling and solar heating from one system, no electricity needed

“Passive cooling, like the shade a tree provides, has been around forever. Recently, researchers have been exploring how to turbo charge a passive cooling technique — known as radiative or sky cooling — with sun-blocking nanomaterials that emit heat away from building …

Raspberry Pi to Z80 interface

“Connect a Z80 CPU to your Raspberry Pi and run machine code on it! This project aims to create a Z80 to Raspberry Pi interface which will be used to map out and run use-case scenarios on the Z80 CPU …

Really random networks - New mathematical method for generating random connected networks

“Many natural and man-made networks, such as computer, biological or social networks have a connectivity structure that critically shapes their behavior. The academic field of network science is concerned with analyzing such real-world complex networks and understanding how their structure …
