Raspberry PI powered Minecraft jack-o’-lantern

Loading

For Halloween this year you may print a large Minecraft jack-o’-lantern after running across this model.

This jack-o’-lantern plays Minecraft music and causes a big RGB LED cube to flicker; when a proximity sensor is tripped, it plays a random spooky noise and flashes the LED red.

Here is the complete write-up, with schematics and such.

How to remove background from images without Photoshop using this free online AI tool

Loading

If you need to quickly remove the background of an image you know how it can be boring, even with access to software like Photoshop. Remove.bg is a single-purpose website that uses AI to do the job for you. Just upload any image and the site will automatically identify any people in it, cut around the foreground, and let you download a PNG of your subject with a transparent background.

It’s the latest example of how machine learning techniques that were once cutting-edge are being turned into simple consumer tools. In the case of removing an image’s background, there are already a few open-source algorithms that can handle this particular task.

Remove.bg

Other similar tools include Deepart.io which applies the style of one image (like a painting) to another, and LetsEnhance.io, which uses AI to automatically upscale pictures. 

AWS launches Robomaker, a platform to test and deploy robotic applications

AWS (Amazon Web Services) has launched AWS RoboMaker, a new cloud service for developers to develop, test, and deploy robotics applications, as well as build intelligent robotics functions using its cloud services.

For this services, AWS has chosen Robot Operating System (ROS) and integrated the same with its cloud environment as an AWS cloud service named RoboMaker. AWS integration of Robot Operating System (ROS) will help developers leverage other AWS’s cloud services such as machine learning, monitoring, and analytics services to enable a robot to stream data, navigate, communicate, comprehend and learn.

RoboMaker essentially serves as a platform to help speed up the time-consuming robotics development process. Among the tools offered by the service are Amazon’s machine learning technologies and analytics that help create a simulation for real-world robotics development. The system can also be used to help manage fleet deployment for warehouse-style robotics designed to work in tandem. “AWS RoboMaker automatically provisions the underlying infrastructure and it downloads, compiles, and configures the operating system, development software, and ROS,” the company writes. “AWS RoboMaker’s robotics simulation makes it easy to set up large-scale and parallel simulations with pre-built worlds, such as indoor rooms, retail stores, and racing tracks, so developers can test their applications on-demand and run multiple simulations in parallel.
