    • Networked Sound with Twin AIO

      Posted on November 6, 2024

      This is a quick setup guide to use the Twin AIO speakers on a home network to stream music. I haven’t seen much information online, so I figured I’d post it here in case it helps anyone else. [Read More]

    • High-Altitude Balloon Kalman Filter

      Posted on May 5, 2023

      From my previous post, I’ve been working on a live-updating prediction model for an APRS-based weather balloon. I am happy to report I have made some minor progress. Take a look! [Read More]

    • Weather Balloon Prediction Model

      Posted on December 16, 2022

      I’ve got a couple of ideas on my sketch pad that I needed to unload into a blog post. Here’s one I’m kicking around for a future date - a predictive model for a landing location of an amateur radio weather balloon. [Read More]
