WiFi Enabled Matrix Lamp

“Who does not want to have stunning lamp which can display animations and sync with other lamps in the house? Right, nobody. That’s why I made a custom RGB lamp. The lamp consists of 256 individual addressable LED’s …

Wurlitzer Key Note Visualizer Replica

“Miniature, portable build of Wurlitzer’s elusive keyboard teaching tool. I am building a replica of Wurlirtzer’s Key Note Visualizer. It’s a simple and beautiful concept: play notes on a keyboard, and watch them light up on the …

A breakthrough in developing multi-watt terahertz lasers

“Researchers at Lehigh’s Center for Photonics and Nanoelectronics are using a new phase-locking technique to achieve record-high output power for terahertz lasers and reported the highest radiative efficiency for any single-wavelength semiconductor quantum cascade laser (QCL). Terahertz lasers could …

A full-duplex tiny AVR software UART

“I’ve written a few software UARTs for AVR MCUs. All of them have bit-banged the output, using cycle-counted assembler busy loops to time the output of each bit. The code requires interrupts to be disabled to ensure accurate timing …

A look at the die of the 8086 processor

“The Intel 8086 microprocessor was introduced 42 years ago this month,1 so I made some high-res die photos of the chip to celebrate. The 8086 is one of the most influential chips ever created; it started the x86 architecture …

A one-way street for acoustic waves

“Device could improve quantum and classical communications If you can hear your neighbors through a shared wall, you better believe they can hear you too. This has nothing to do with your annunciation and everything to do with a fundamental …

A portable methanol detector

“ETH researchers at the Department of Mechanical and Process Engineering have developed a device that detects low concentrations of methanol in alcoholic beverages. The results are displayed on a smartphone wirelessly in real time. Methanol can be lethal, even if …

A spreadable way to stabilise solid state batteries

“Solid state batteries are of great interest to the electric vehicle industry. Scientists at Chalmers and Xi’an Jiaotong University, China now present a new way of taking this promising concept closer to large-scale application. An interlayer, made of a …

A Startling Excess of Particle Detections by the XENON1T Could Point to New Physics

“A strange thing happened while running the most sensitive dark matter detector built to date, known as XENON1T. Having painstakingly accounted for all known sources of particles that could trigger the exquisitely sensitive apparatus, researchers confidently expected 232 triggering events …

A surprising quantum effect observed in a “large” object

“While conducting experiments on a layered metal, EPFL researchers witnessed something very surprising. The unexpected electron behavior they discovered could open up possibilities in the field of quantum computing. In the world of materials science, sometimes main discoveries can be …
