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 self-hosted DXCC hunt board: multi-station ADIF upload (old call plus current), confirmed entities on a world map, watchlist pins for the next All Time New One, and beams from the home grid. Open source.
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.
A browser-based dashboard for a Meshtastic LoRa mesh node: live map, messaging with RF/MQTT delivery tracking, full config and channel editing, and a chart correlating airtime congestion with ack success. Open source.
Private System Fusion link from an HT to the station agent and back. Talk into a Yaesu FT-70D, get spoken answers: fleet status, location, traffic, weather, solar, radio quick-refs, and more. Truck and home hotspots share one conversation.
Pure-Python YSF V/D Mode 2 frame encoder (and DVSwitch AMBE/TLV daemon) for originating System Fusion voice from software you control. No vocoder: framing and FEC only. GPL-2.0-only.
M5Stack Cardputer ADV with multi-boot via M5Launcher: Bruce, Meshtastic, and a station HUD firmware on one SD, plus Cap LoRa and GPS. Companion server on the home Pi.
Thermocouple-based BBQ smoker monitor with stall and flameout detection and phone alerts — because good brisket deserves good telemetry too.
Victron BLE telemetry from the solar shed on a Pi Zero, with a cyberpunk dashboard for charge state, yield, and battery health.
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.
