Playing Full PC Games on a RaspberryPi 4

Playing a variety of PC games on Raspberry Pi 4 has long been a pipe dream, but not anymore. Thanks to advancements in emulation with box86, open source games with doom 3, or just the ingenuity of some frameworks the situation for running full PC games (even Steam games on a raspberry pi 4 windows 10 like environment) is looking bright for raspberry pi os.

This ephemeral display shows messages using floating bubbles

While electronics and water don’t generally mix, researchers at Ochanomizu University in Japan have come up with an ephemeral display method that uses floating clusters of bubbles to show messages on a liquid surface.

The device, known as UTAKATA, utilizes a line of seven electrodes under Arduino Uno control that activate to form hydrogen bubbles via electrolysis. When arranged properly, these bubbles can be made to produce letters and words, which as shown in the video below, dissipate as they flow downstream in the container.

Create Home Automation with Arduino IoT Cloud

 was always inspired to live in a smart home where I can automate some of the everyday tasks to make life easier and comfortable. For example, how many times does your TV remote disappear, and you just wish to say a voice command to do the task for you instead? Many Smart TVs do this already, of course, but buying a good one can be a bit expensive. In this project, I describe how easy it is to make some of your home appliances smart with an Arduino board. Besides controlling the TV with voice, I will use a temperature sensor, motion sensor, and an RGB LED to demonstrate the Arduino MKR WiFi 1010 capabilities. I will also connect the Arduino board to an Amazon Alexa device, and then you can set up some routines for your home automation.

World’s First IRL STAR WARS Protosaber Is Insanely Dangerous


Here’s the thing about lightsabers that isn’t acknowledged enough: They’re just as dangerous for their users as they are for enemies facing off against them. Which isn’t a big deal considering the elegant weapons for a more civilized age are fictional, but in real life, this fact becomes frightening relevant. Check out the Hacksmith’s “world’s first protosaber” build for proof of that assessment, as well as an understanding of why a true energy sword is not only nearly impossible to build, but also unwise to wield.
