3D printed microboat

“From prow to stern, this little boat measures 30 micrometers, about a third of the thickness of a hair. It has been 3D-printed by Leiden physicists Rachel Doherty, Daniela Kraft and colleagues. The image was made using an electron microscope …

A flexible color-changing film inspired by chameleon skin

“Chameleons can famously change their colors to camouflage themselves, communicate and regulate their temperature. Scientists have tried to replicate these color-changing properties for stealth technologies, anti-counterfeiting measures and electronic displays, but the materials have limitations. Now, researchers have developed a …

A New Ultrafast Control Scheme of Ferromagnet for Energy-Efficient Data Storage

“The digital data generated around the world every year is now counted in zettabytes, or trillions of billions of bytes - equivalent to delivering data for hundreds of millions of books every second. The amount of data generated continues to grow …

A Simple Stand for an Acoustic Levitator MiniLev

“This project would not be possible with the amazing project that Dr. Asier Marzo created. https://www.instructables.com/Acoustic-Levitator/ Like all good projects, this one started out simple and grew as time went on. After reading Dr. Marzo intractable …

A trillion turns of light nets terahertz polarized bytes

“Nanophotonics researchers demonstrate ultrafast polarization switching U.S. and Italian engineers have demonstrated the first nanophotonic platform capable of manipulating polarized light 1 trillion times per second. “Polarized light can be used to encode bits of information, and we’ve …

A wearable sensor to help ALS patients communicate

“Researchers have designed a skin-like device that can measure small facial movements in patients who have lost the ability to speak. People with amyotrophic lateral sclerosis (ALS) suffer from a gradual decline in their ability to control their muscles. As …

AM/FM/SW Radio Receiver - Si4730 / Si4735

“DIY AM/FM/SW/ DSP radio receiver, using Arduino Uno/Nano and a color display TFT ST7735 1.8in. This is my design of a AM / FM / SW radio receiver with DSP technology. Features: This Arduino radio receiver has an …

Arduino Compatible 2-Digit 7-Segment Display Board For Timer/Counter

“The project presented here is an open source 2-digit 7 segment Arduino compatible display board. It can used in many applications that require 2-digit display and switches inputs. Possible application of this board is a 2-digit counter, 2-digit countdown timer …

Arduino: Continuous MIDI Controller / KeyBoard

“This instructable Making a Continuous type MIDI controller / Keyboard is explained. A very simple concept of capacitive sensing is used along with MIDI communication and sound synthesizer software. You may refer Attached video for a quick demonstration or you may …

Arduino Plant Water Management System w/ BME280

“Track the total volume of water spent and evaluate approx. evaporation rates by temperature, humidity, and pressure to prevent water overuse Especially during a pandemic related to a virus that washing your hands is efficient to stop its spreading, it …
