    Keep tabs on your home’s energy consumption and production in real-time with this Raspberry Pi setup.

    Monitor Your Home’s Power Consumption with Raspberry Pi
    https://www.hackster.io/news/monitor-your-home-s-power-consumption-with-raspberry-pi-b2049340bbba

    This combination of custom hardware and software allows you to keep tabs on energy consumption and production in real-time.

    The system is designed around a Raspberry Pi 3B+ and uses a Microchip MCP3008 analog to digital converter, and Kill-A-Watt energy meter to monitor up to six current transformers, along with a single AC voltage reading. David then wrote some code that takes those readings and transforms them into live data on power consumption and generation.

    Wooden home furniture possesses something very organic regarding it.
    There is this sense of warmth, of nature and also of luxury that could be be discovered in wood furniture.
    Wood is actually born coming from the earth. It feeds the
    fire, breaks down in to ashes and drafts away. It is actually very near the human existence in the world.
    May be that is why it resonates a great deal along with our team.
    When you touch an abundant mahogany workdesk, might
    be that is why you still obtain that warm and comfortable emotion.

    Control Electronics Just by Looking at Them with Hypervisor
    https://www.hackster.io/news/control-electronics-just-by-looking-at-them-with-hypervisor-66c72addf818

    This wearable headset lets users with physical disabilities operate their touchscreen devices by simply looking at them and blinking.

    Those who struggle to use their hands can find interacting with touchscreens to be a very difficult task. That’s why Zack Freedman created Hypervisor, which is a wearable device that is able to track a user’s eye movements and pupil positioning to place a mouse cursor on a screen. He built the head-mounted unit as an entry for the 2020 Hackaday Prize to fulfill the needs of United Cerebral Palsy.

    How to replace your laptop’s optical drive with a Raspberry Pi

    Raspberry Pi Zero Replaces Broken Laptop Optical Drive
    https://www.tomshardware.com/news/raspberry-pi-zero-replaces-broken-laptop-optical-drive

    Sometimes a broken laptop is an opportunity for invention. This project was created and shared by a maker who goes by Ollie242. After a malfunctioning optical drive proved to be more of a burden than a feature, Ollie242 decided to remove it completely. With a gaping hole in the side of the laptop, the decision was made to install a Raspberry Pi Zero W in its place.

    The Raspberry Pi is embedded in the laptop hardware and even draws power from it. Ollie242 included a breadboard that slides out with the Pi that can be used for projects whenever you want.

    Ollie242 powers the Pi using a male to female slimline SATA cable connected directly to the laptop. To access the Pi, VNC is used to remote into the system, eliminating the need for any additional peripherals. The laptop screen, cursor and keyboard can be used to control the Pi.

    This is a ‘Spot Micro’ walking quadruped robot running on Raspberry Pi 3B. By building this project, redditor /thetrueonion (aka Mike) wanted to teach themself robotic software development in C++ and Python, get the robot walking, and master velocity and directional control.

    And yes, this is one of those magical projects with all the code you need stored on GitHub. The software is implemented on a Raspberry Pi 3B running Ubuntu 16.04. It’s composed on C++ and Python nodes in a ROS framework.
