News Wind turbine data from the island of Bornholm confirms potential of high-efficiency electrolysis cells
“Using wind data from a wind farm on the Danish island of Bornholm, researchers from DTU Energy and partners have successfully tested the ability of electrolysis cells to store wind power. An electrolysis cell uses electricity to split, e.g …
“Previously, we looked at using registers directly in Arduino and setting up external interrupts. This time, we configure a timer interrupt to toggle an LED every 0.5 seconds. That’s right; we’re going to redo blinky the hard …
“This is an easy to build pet feeder with 2 timers and accurate portions delivered each time. Why another Pet Feeder? My version of a pet feeder is based on an Arduino microcontroller. The materials used are relatively cheap and …
“In this project we will have a look at peristaltic pumps and find out whether it makes sense to DIY our own version of it or whether we should just stick with the commercial buy option instead. Along the way …
“A 29-minute trip from D.C. to New York may seem too good to be true. And it very well may be. But that isn’t stopping Elon Musk from pushing forward with plans to build a Hyperloop along the …
“Amblyopia (lazy eye), a disorder of sight that affects approximately 3% of population, usually treated by simple eyepatches or atropine drops. Unfortunately, those methods of treatment occlude stronger eye for long, uninterrupted periods of time, not allowing two eyes (actually …
“Palmreading could take on a whole new meaning thanks to a new invention from Japan: an ultra-thin display and monitor that can be stuck directly to the body. The band-aid-like device is just one millimeter thick and can monitor important …
“We present the Robotic Modeling Assistant (RoMA), an interactive fabrication system providing a fast, precise, hands-on and in-situ modeling experience with an augmented reality CAD editor and a robotic arm 3D printer. As a designer creates a new model using …
“The Talking Clock 2 (Bilingual) is the new version of Talking Clock I have published some time ago. The code was updated to support two languages (English/Portuguese) and new features were introduced into the code: Mode 1: Set the …
“This article describes a simple function generator based on an ATtiny85. It can generate triangle, sawtooth, square, and rectangular waves, a pulse train, and noise. The frequency can be adjusted using a rotary encoder between 1Hz and 5kHz in steps …
