New Guide in the Adafruit Learning System from John Park: Cartoon Network MakeCode: Garnet’s Gauntlets from Steven Universe
Make these fun gauntlets using craft foam and a light up, punch-reactive Circuit Playground Express that flashes and plays sound when shaken. Uses the built-in accelerometer!

Have video cameras around your home and property for home defense? Have an easy way to display them? In today’s article, I’m going to walk through turning a Raspberry Pi into a video surveillance monitoring system. You can hook up the Raspberry Pi to your TV or any other monitor you have lying around to create your very own video surveillance system.

The motivation for making this project came from a story told me by a friend (Douglas Vieira), in fact a sad story. Douglas has told me that one of his relatives had a serious illness, and was alone in a day that has collapsed. Douglas’ relative wasn’t familiar with technology and had some difficulties to use cellphones/smartphones, what made the situation worse: help couldn’t be called. Unfortunately, Douglas’ relative has been found some hours after collapse only, and even going to hospital / emergency hasn’t survived. Douglas told me that if his relative had a device really easy-to-use to call for help, maybe had a chance to survive. Also, considering that another one of Douglas’ family members are in similar condition (serious illness and/or elderly people), the idea of a emergency device made more sense.

Mukut Mukherjee on Medium breaks down the process of building an autonomous drone!
Thanks to science and technology, our fascination with angels have been replaced with that of autonomous drones, machines that are capable of flying by themselves.
Building autonomous drone, or even understanding them could be extremely taunting. So let’s break this down.
The first step towards the automation of our drone would be replacing the radio with an onboard computer. Speaking of onboard computers for the drone, I hope, that a Lenovo Thinkpad would not be the first thing that pops to mind. We can make good use of the Raspberry Pi here. Even an Arduino would perform in this situation, though it is not a computer, but a micro-controller. I have tried and tested both of them and the Pi, because of its greater computational power, would be best suited in this quest to make the drone autonomous. But, how does replacing the radio with the Pi help us achieve our goal? Well, with the Pi we can connect a wide range of external sensors and run different mapping, localization, and or image processing algorithms, do all the fun stuff basically. But first up, we need to mimic the radio transmitter signals that served as inputs for our flight controller.
