Summer Project – Make an INSANELY LOUD Bluetooth Amplifier!

In this video we’ll be making a wireless bluetooth-enabled amplifier so that we can put old bookshelf speakers to good use!
Not only is the sound quality fantastic, but it can also go super loud! It’s also quite easy to build, and doesn’t require any special tools – you can get away with just a hammer, nail, and a screwdriver if needed. Seriously!

Qt Introduces Bare Metal Toolkit for Microcontrollers

Creating modern user interfaces for embedded systems just got easier. The Qt Company has announced its new toolkit: Qt for MCUs. If you have not heard of Qt before, it is probably best known as a GUI toolkit for cross-platform applications.
The new Qt for MCUs lets you skip the operating system and run a graphical user interface on bare metal microcontrollers.

3D Printing of Nonplanar Layers for Smooth Surface Generation

Additive manufacturing processes are inherently subject to discretization effects. For most technologies, stair-stepping artifacts impair the surface quality of 3D printed objects, especially when the surface slope is close to horizontal.

In this video we propose a novel Fused Deposition Modeling (FDM) slicing approach that combines nonplanar and planar layers, increasing printing quality and resulting in smoother, stronger object surfaces. Our slicing algorithm automatically detects which parts of the object should be printed with nonplanar layers and uses a geometric model of the printhead and extruder to generate collision-free toolpaths.

Intel’s 10th-gen CPUs for powerful ultraportables will reach six cores

The big selling point with Intel’s first 10th-gen Core processors is the company’s new 10nm architecture, the result of a long journey towards shrinking down its production process. It’s a much more efficient design, which will lead to both power savings and better performance.
But the next batch of 10th-gen chips, codenamed “Comet Lake,” won’t be taking advantage of that new technology. Instead, they’re more powerful 14nm chips meant for heavier workloads in thin and light machines.
