Robin @ kickstarter.com launched his new campaign on a project using IN-9 Nixie tubes. Now you can easily control two IN-9 Nixie bargraph tubes with 2 PWM inputs from your Arduino, Raspberry or other control board. The tubes are controlled by PWM signals and adjusting the PWM duty cycle you can control the tubes height, […]
µduino, The Smallest Arduino Ever
https://www.electronics-lab.com/%c2%b5duino-smallest-arduino-ever/
A new member to Arduino compatible devices is just here, the newest yet the smallest Arduino ever created, µduino!Believing that it is enough to include some bulky devices in our applications, the team behind µduino is trying to provide a shrinkified device that can be included anywhere. With the size of 12mm (0.5 inches) x 12mm, µduino is […]
The First 3D Quantum Liquid Crystals
https://www.electronics-lab.com/first-3d-quantum-liquid-crystals/
Strong electron interactions can drive metallic systems toward a variety of well-known symmetry-broken phases, but the instabilities of correlated metals with strong spin-orbit coupling have only recently begun to be explored. A team of physicists at the Institute for Quantum Information and Matter at Caltech, had discovered an new state of matter that may have applications […]
Electrolytic + polymer = the hybrid capacitor
https://www.electronics-lab.com/electrolytic-polymer-hybrid-capacitor/
Electrolytic capacitor is often a common reason for device failure and replacement is necessary. But what if we could combine the benefits of electrolytics and polymer capacitors. Now you can have the best of both worlds: hybrid capacitors from have been designed to combine the advantages of electrolytic capacitors with those of solid polymer capacitors. […]
USB 3.0 NanoHub
