Colour-changing magnifying glass gives clear view of infrared light

“By trapping light into tiny crevices of gold, researchers have coaxed molecules to convert invisible infrared into visible light, creating new low-cost detectors for sensing. Detecting light beyond the visible red range of our eyes is hard to do, because …

Constraining quantum measurement

“The quantum world and our everyday world are very different places. In a publication that appeared as the “Editor’s Suggestion” in Physical Review A this week, UvA physicists Jasper van Wezel and Lotte Mertens and their colleagues investigate how …

Conversation Face

“You are alone? Maybe in quarantine? Need someone to talk to? Or just a friendly listener? Or do you want to have a nice argument? Your robot needs a cute face? Conversation face can help you. Supplies: - Arduino nano/Wemos …

Creating 3D maps with a backpack

“In case of an emergency, up-to-date information about the inside of buildings needs to be readily available for first responders. UT researcher Samer Karam developed a wearable mapping system (the ITC-Backpack) that can map building interiors in mere minutes …

DIY 3D Resin Curing Station with Wio Terminal

“I decided to venture into the world of 3D resin printing after years of immersion using FDM (fused deposition modeling) printing. For those who are unfamiliar with this, it’s like squeezing toothpaste onto a surface. I have a Lulzbot …

DIY Pen Plotter with Automatic Tool Changer | CNC Drawing Machine

“In this tutorial I will show you how I built a CNC pen plotter or a drawing machine but with one cool feature and that’s automatic tool change. In other words, the machine will be able to automatically change …

ESP32 Secure Firmware Update Over-The-Air (OTA)

“Once you deploy your IoT device, you won’t have physical access to reprogram or update it. It is critical to plan ahead and to have a secure mechanism for updating your embedded system or IoT device. Sometimes you will …

Finland’s first 5-qubit quantum computer is now operational

“With this milestone, VTT and IQM take a step closer to making quantum computers manufacturable, scalable and more accessible for the world. ESPOO, Finland (November 30th, 2021) Today, VTT Technical Research Centre of Finland announced that the country’s first …

Green information technologies: Superconductivity meets Spintronics

“Superconducting coupling between two regions separated by a one micron wide ferromagnetic compound has been proved by an international team. This macroscopic quantum effect, known as Josephson effect, generates an electrical current within the ferromagnetic compound made of superconducting Cooper-pairs …

Hello, my name is: a wearable name badge

“A programable and wearable electronic name badge that scrolls a name over several LED matrixes. A makerspace I’m a part of has a night that we’re open to the public for people interested in joining. It’s a …
