    Internet of Skull: An Internet Status Monitor


    Maker Emily Velasco is known for her unique projects and the Internet of Skull is no different: “I live in a neighborhood with an internet provider of so-so quality. When the service works, it works well, but it goes down more often than it seems like it should for the $75 a month I have to pay for it.” This project monitors Emily’s home network status and displays it using an RGB LED for visual feedback. The project is mounted inside a fake skull, giving it a unique, biological, look. -MLE-Online

    Text to update this RGB LED Matrix


    Send text messages that magically scroll across a RGB LED matrix in bright colors. Update the sign from anywhere, or give the control to your employees or family members, since there’s no coding or computer needed to update your sign. -Adafruit Learning System

    CAN Bus Sniffing with ESP32


    The CAN bus, accessible through your car’s OBD-II port, is a channel holding real-time data from your car. EQMod developed an ESP32-powered dongle that plugs into an OBD-II port and can be used to sniff CAN bus data. Data is displayed on a self-hosted webpage. -HackADay

    Antique (Internet) Radio


    Craig Lindley built a vintage-style radio that plays music from an internet radio station. The enclosure is made from 1/8” baltic birch and the radio itself is powered by an ESP32 WROOM. -HackADay

    PeggyBoard: An Interactive Climbing Wall


    The PeggyBoard is “a Raspberry Pi project developed to be paired with your home “woody”/climbing wall. It features an easy-to-use web app that anyone on your network can open up and begin setting a custom route that will then light up the respective holds on your wall. These routes can also be saved so they can be revisited later.” - GitHub

    Bright Block: A Bike Gizmo for Urban Science


    Kelsey’s bike light does a bit more than we’d expect from a standard bike light. It’s also a climate monitor “built to capture and characterize several aspects of biking in the city”. As the cyclist rides, it measures and maps environmental data around the city, including temperature, humidity, and air quality. - HackADay

    LED Matrix Sports Scoreboard


    If you’ve ever wanted to see all of your sports stats in one spot, this project is for you. You can build a large RGB LED matrix display to monitor your favorite s teams. A Matrix Portal S3 running CircuitPython requests data from the ESPN API to show your teams’ gameplay data alongside team logos that are resized and gamma-corrected to look crisp and bright on the matrices. - Adafruit Learning System

    A Cheap but Precise Weather Station


    JP Gleyzes built a long-range weather station for their RC flying club. “These (wind) conditions are locally changing quite fast and the weather forecast is not accurate enough for our hobby”. The weather station’s feed can be accessed via this link. - HackADay

    Hot Tub Monitoring Machine


    Stephen’s hot tub monitoring system uses commercial sensors to track their hot tub’s water quality measurements. The system uses an ESP32 to read the sensors and send out the data to Home Assistant. They’ve included a “calibration mode” that verifies their sensor reads against a hot tub with a known good buffer solution. - HackADay

    Smart Plant Monitor with E-Ink Display


    This plant monitor is neat because it “takes advantage of the ESP32-S3’s touchpad feature which has all the circuitry needed to monitor (soil) capacitance”. - HackADay.io

    BirdNETPi - a real-time acoustic bird classification system


    BirdNET is an audio analyzer built around TensorFlow Lite. It runs on a Raspberry Pi and “is able to recognize bird sounds from a USB microphone or sound card in real-time and share its data with the rest of the world” - GitHub

    OpenMower - DIY Smart Mowing Robot


    The OpenMower project alleges that inexpensive off-the-shelf robotic mowers aren’t great! They “drive in a random direction until they hit the border of the lawn, rotate for a randomized duration, and repeat”. Instead of this basic operation, OpenMower is improving its mowers through open-source, community-built, software. - GitHub

    Album Art for Turntables


    Paul Cutler built an RGB matrix that can display the album art of whatever is spinning on a turntable. From a website, he picks the album he’s listening to, a script converts the image into a bitmap, and the bitmap is sent over MQTT to an RGB matrix that’s sitting on his desk. - prcutler on Mastodon
