“Utilizing only the cheap components required for regular sensor functionality, this ATtiny212-based design adds two-way wireless communication for tweaking and reporting of its own parameters. Here’s how it came to be. Background A client’s project used a certain …
“MPU-6050 is an accelerometer & gyroscope sensor which interfaced with Arduino nano can detect tilt while using LEDs as visual indicators. The tilt detection system is a project that utilizes Arduino Nano, MPU-6050 accelerometer and gyroscope module, and 11 …
“Researchers at NTNU have found a way to make gold nanoparticles with a uniform size and shape, opening up the possibility of finding more effective photocatalysts. When organic pollutants such as dyes, agricultural chemicals, and pharmaceuticals enter waterways all around …
“Martian maps are full of monikers recognizing places on Earth, explorers, and even cartoon characters. NASA’s Perseverance rover is currently investigating rock outcrops alongside the rim of Mars’ Belva Crater. Some 2,300 miles (3,700 kilometers) away, NASA …
“Hey everyone, what’s up? Hey here’s something helpful: a home automation shield designed for Seeed XIAO DEV boards with a single SPDT relay and inbuilt AC-DC power so we can run this board directly off an AC …
“Researchers develop an algorithm that decides when a “student” machine should follow its teacher, and when it should learn on its own. Someone learning to play tennis might hire a teacher to help them learn faster. Because this teacher is …
“In 2021, lanthanide-doped nanoparticles made waves — or rather, an avalanche — when Changwan Lee, then a PhD student in Jim Schuck’s lab at Columbia Engineering, set off an extreme light-producing chain reaction from ultrasmall crystals developed at the Molecular Foundry …
“The absolute internal quantum efficiency (IQE) of indium gallium nitride (InGaN) based blue light-emitting diodes (LEDs) at low temperatures is often assumed to be 100%. However, a new study from University of Illinois Urbana-Champaign Electrical and Computer Engineering researchers has …
“Robotic device for improving post-stroke gait could enable walkers to benefit during their daily routines. Every 40 seconds, someone in the United States has a stroke. According to the U.S. Centers for Disease Control and Prevention, that totals about …
