I have seven Raspberry PIs on my network. Each one has a completely different job: (more articles to come soon!)
1. LeeRoy Monitor — tracks my robot lawn mower with an ultrasonic sensor, snaps photos, sends Discord alerts if he's been gone too long, and has his own website 2. HAM Radio — runs fldigi and WSJT-X for digital amateur radio modes 3. NHL Dashboard — Predators game tracker with live scores and highlights 4. ADS-B Flight Tracker — receives aircraft transponder signals and feeds data to FlightAware 5. PiKVM #1 — remote keyboard/video/mouse access to my pfSense router 6. PiKVM #2 — remote KVM for my GPU server (for when it locks up) 7. FreePBX — full Asterisk phone system with VoIP.ms trunk, IVR, and voicemail
Total investment across all seven: roughly $500. What they replace: thousands in commercial equivalents.
The Raspberry Pi isn't a toy. It's a Swiss Army knife for infrastructure. Each one runs 24/7 with near-zero power draw, doing a job that would otherwise require dedicated hardware or a cloud subscription.
My favorite part? My 8-year-old (now 9) knows what each one does. "That's the lawn mower one. That one tracks airplanes. That one is for daddy's radios."
