Raspberry Pi B: Stream a local ham radio repeater (weather spotters) to Broadcastify Raspberry Pi Zero: Brachiograph Raspberry Pi 4B: Octoprint Raspberry Pi 4B: Home Assistant Raspberry Pi 4B: NAS (running Kopia as backup target w/ USB HDD, not speed-critical) Raspberry Pi Zero 2W: ham radio-related software for portable use (e.g. WSJT-X, etc.) using cell phone via WiFi as display/input via RDP To do: MiniDexed synth module, eInk display driver, network a UPS via NUT, RetroPie, Ham Clock, etc., etc. I've also used them previously as a fax server, digital signage for office lobby, and other things I'm forgetting

With this many pis, what's stopping you from buying an old workstation that can run all of those systems concurrently?

  Management simplicity, probably. There are many pre-made images you can just flash on an SD card and have run perfectly. Computationally you could very likely run all of the services on a single Pi just as well.

  Most of these live in different locations, or are portable.

> Raspberry Pi Zero 2W: ham radio-related software for portable use (e.g. WSJT-X, etc.) using cell phone via WiFi as display/input via RDP I would be interested in a write up about this or hearing more. I let my HAM lapse, but recent got into GMRS. No test required for the license, and way more 'simple'.

  The very basics of it are that I'm trying to operate portable using HF (<30MHz, long range), including for digital comms such as FT8. Typically a computer generates the audio-band signals which are transmitted as RF by the radio. Skipping the laptop (less to carry/power), I've installed a few of these ham apps on the Pi, power it from the radio's battery, and use an adapter (Digirig) to give me serial and audio to the radio. I turn on my phone's hotspot, the Pi connects via WiFi, and I use RDP to remote into the Pi, using my phone as the input and display. The Pi Zero 2W is a little under-powered (mostly needs more RAM), but it does the trick. The simplicity of GMRS can be good, but for me I rarely use a radio to talk locally on repeaters. I like the idea of communicating as far as possible on very little power (QRP) with a small footprint, and the experimentation angle of it all.
