Visualizing Sorting Algorithms

“For my workforce development class, I show how a sorting algorithm works using NeoPixels (red larger, blue smaller). A common starting point for learning about algorithms (and their complexity - big O notation) is sorting algorithms. It dawned on my that …

Weather station

“This project measures the temperature, humidity, atmosferic pressure (and much more… ) and display then on a web page. Hello this project uses a arduino nano 33 IOT, a BME280 and an i2c oled display. After power up, the software connects …

World’s first optical atomic clock with highly charged ions

“Optical atomic clocks are the most accurate measuring instruments ever built and are becoming key tools for basic and applied research, for example to test the constancy of natural constants or for height measurements in geodesy. Now, researchers at the …

3D Printed Berlin Uhr

“Once in the year 1980 I was young and handsome. Now I’m only and. One a school trip to Berlin I saw a beautiful digital clock with a futuristic design. I decided right away to build this clock myself …

5.1 channel analog audio processor

“This project is a 5.1-channel, analog audio processor based on PT2322 and Arduino Nano. In this project, we developed a 5.1-channel analog audio processor using PT2322 IC. PT2322 is an inexpensive analog audio processor introduced by Princeton Technology …

A faster experiment to find and study topological materials

“Using machine learning and simple X-ray spectra, researchers can uncover compounds that might enable next-generation computer chips or quantum devices. Topological materials, an exotic class of materials whose surfaces exhibit different electrical or functional properties than their interiors, have been …

A laser that could ‘reshape the landscape of integrated photonics’

“Rochester researchers see applications in LiDAR, atomic physics, AR/VR. How do you integrate the advantages of a benchtop laser that fills a room onto a semiconductor chip the size of a fingernail? A research team co-led by Qiang Lin …

A traveler from the edge of the Solar System

“Iron isotopes in samples from asteroid Ryugu suggest its origin to lie beyond the orbits of Jupiter and Saturn Astronomy Astrophysics Solar System The asteroid Ryugu likely formed at the outer edge of the Solar System beyond the orbits of …

An Entangled Matter-Wave Interferometer: Now With Double the Spookiness!

“JILA and NIST Fellow James K. Thompson’s team of researchers have for the first time successfully combined two of the “spookiest” features of quantum mechanics to make a better quantum sensor: entanglement between atoms and delocalization of atoms. Einstein …

Arduino hearing test device - Audiometer

“An audiometer is a machine used for evaluating hearing acuity. An audiometer is a machine used for evaluating hearing acuity. They usually consist of an embedded hardware unit connected to a pair of headphones and a test subject feedback button …
