Game-changing finding pushes 3D printing to the molecular limit

“New University of Nottingham research proves that advanced materials containing molecules that switch states in response to environmental stimuli such as light can be fabricated using 3D printing. The study findings have the potential to vastly increase the functional capabilities …

Ground-breaking discoveries could create superior alloys with many applications

“Many current and future technologies require alloys that can withstand high temperatures without corroding. Now, researchers at Chalmers University of Technology, Sweden, have hailed a major breakthrough in understanding how alloys behave at high temperatures, pointing the way to significant …

HackSpace magazine #8

“Go behind the scenes at Arduino to find out the story behind the hottest microcontroller releases of the year – the new version of the Uno, the line of MKR boards, and their very first FPGA. Hardware development has never been …

How to control robots with brainwaves and hand gestures

“Computer Science and Artificial Intelligence Laboratory system enables people to correct robot mistakes on multiple-choice tasks. Getting robots to do things isn’t easy: Usually, scientists have to either explicitly program them or get them to understand how humans communicate …

IC Egg Timer

“This project demonstrates the basics of digital logic, the characteristics of a NE555 timer, and demonstrates how binary numbers are counted. The components used are: a NE555 timer, a 12-bit ripple counter, two 2-input NOR gates, a 4-input AND gate …

Interaction of paired and lined-up electrons can be manipulated in semiconductors

“The way that electrons paired as composite particles or arranged in lines interact with each other within a semiconductor provides new design opportunities for electronics, according to recent findings in Nature Communications. What this means for semiconductor components, such as …

Low-cost and precise rotary encoder with magnetic spheres

“You know what they say that constraints drive creativity, I think this post is just another little example of that. Usually I do not put time constraints to my hobby projects, but I make sure to have some other kind …

New ‘E-Dermis’ Brings Sense of Touch, Pain to Prosthetic Hands

“Amputees often experience the sensation of a “phantom limb”—a feeling that a missing body part is still there. That sensory illusion is closer to becoming a reality thanks to a team of engineers at the Johns Hopkins University that …

Not always bad-MXenes’ spontaneous oxidation harnessed to create 2-D nanocomposites

“Researchers at Missouri S&T have discovered a new way to harness the potential of a type of spontaneously oxidized MXene thin films, to create nanocomposites that could sense both light and the environment. Previously, such spontaneous oxidation was considered …

Pan and Tilt Mechanism for DSLR Time Lapses

“I had a few stepper motors lying around and really wanted to use them to make something cool. I decided that I would make a Pan and Tilt system for my DSLR camera so that I can create cool time …
