Graphene Quantum Dots for Single Electron Transistors

“Scientists from the Higher School of Economics, Manchester University, the Ulsan National Institute of Science & Technology and the Korea Institute of Science and Technology have developed a novel technology, which combines the fabrication procedures of planar and vertical heterostructures in …

Gyroscopic 3D wireframe cube | Using a 3-axis gyro for live 3D perspective

“This little project combines the previous accelerometer-gyroscope code with the 3D rotating OLED cube to produce a 3D cube which responds to gyro input, making it possible to “peek around” the cube with simulated perspective, or make it spin with …

High-speed 3D printer for high-performance plastics

“The additive manufacture of large-volume plastic components is a time-consuming undertaking. Researchers at the Fraunhofer Institute for Machine Tools and Forming Technology IWU have now developed Screw Extrusion Additive Manufacturing (SEAM), a system and process that is eight times faster …

How to Build a Secret Barn-Wood Infinity Lamp

“There’s something so captivating about infinity mirrors. Maybe they just look cool or maybe they just remind me of being a kid and looking down the shelves in the produce aisle. Either way, dad and I really enjoyed making …
