Everything below runs on a Raspberry Pi 5 at home, built and maintained solo. They're private systems — not publicly reachable — but here's what they do.
An ESP32 + CC1101 SDR decodes a local AcuRite 5-in-1 weather station straight off the air, feeding a live dashboard with wind vectors, feels-like heat index, and NWS alerts.
An RTL-SDR watches 40m–10m for WSPR beacons around the clock, with smart band rotation and a greyline propagation map, uploading every decode to wsprnet.org.
A Direwolf-based APRS digipeater and internet gateway (WY6Y-7) with a live packet map, in-app messaging, and its own weather beacon (WY6Y-13).
A browser-based CAT control app for the FTDX10, built to replace a Windows-only tool — includes a live waterfall panadapter.
A repurposed touchscreen mounted in the shack, pulling weather, APRS, and smoker status into one glanceable panel.
A remote-controlled RF switch for selecting between HF antennas from the shack, built around a Raspberry Pi Zero with a small web control panel.
A compact home-built magnetic loop, 20m–10m, with a butterfly variable capacitor — the full build documented start to finish on YouTube.
Thermocouple-based BBQ smoker monitor with stall and flameout detection and phone alerts — because good brisket deserves good telemetry too.
A whole-home dashboard tying together irrigation, climate, cameras, and UPS power monitoring across the property.
A traffic-light security dashboard watching every device on the home network for drift, stale credentials, and misconfiguration — built after one too many silent failures.
