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

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
