Librem 14 Runtime and Charging
The Librem 14 has a powerful 66.8Wh battery; let’s dig into what that means for runtime and charging.
The Librem 14 gets around 9 hours and 48 minutes with the screen on max brightness and all sensors enabled. This is the uptime you can expect with light use, like reading a text document or other simple low CPU programs.

Mr Innovative’s resistor cutting machine is 'reely' awesome | Arduino Blog
If you need some help separating out lots of resistors, then Mr Innovative’s latest automated rig is the perfect solution for you. At the heart of his homemade device is an Arduino Nano, along with a multipurpose PCB for electrical connections and a touchscreen user interface.
The machine advances the reel of resistors through a slot via a stepper-driven rod and o-ring friction wheel assembly. When properly positioned, it cuts off the correct number of resistors using a pair of razors, set in motion by two stepper motors and corresponding linkage systems.

Arduino plays the Chrome Dinosaur Game on another Arduino | Arduino Blog
There has been a trend over the past few years to automate certain games using microcontrollers — especially mobile ones. But none are perhaps as popular as the Dinosaur Game that shows up whenever the Chrome browser lacks an Internet connection. The game is simple: just tap or click to make the little T-Rex jump over various obstacles. And even though Arduino projects already exist that play perfectly for you and run the game, what about combining the two? This exactly what Michael Klements did with his Arduino Uno that plays the dino game on another Uno.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
