I had one of the original 2012 Model B's (with the 256MB RAM) serving as a simple web server for years. I just recently retired it in favor of a VM.

Other than that, I have:

- A RetroPie attached to my living room TV

- A Zynthian (http://zynthian.org/)

- A PiDP-11 (https://obsolescence.wixsite.com/obsolescence/pidp-11)

In the past, I've played around with them, making:

- A touch-screen enabled stand-alone SunVox synth

- A home audio server attached to my stereo

- An experiment to read MIDI files from floppy disks, also attached to the stereo

I have a couple spares laying around waiting for use cases... but I'm not really antsy to get to them. I'd love to build an OTTO (https://github.com/topisani/OTTO) when it's ready for prime time. I'm also considering building some sort of portable RetroPie.

I have 13 in service right now: - Outdoor irrigation control via OpenSprinkler Pi: https://opensprinkler.com/product/opensprinkler-pi/ - Z-Wave home automation via ZWay: https://z-wave.me/products/razberry/ - 2 Custom HAVC thermostats using: https://github.com/jeffmcfadden/PiThermostat - An NTP server with GPS attached for a time source. - 2 for weather monitoring (one directly attached to sensors, one that aggregate…

>2 for weather monitoring (one directly attached to sensors, one that aggregates the data from a few sources and provides reporting) So, I hear people doing this alot. However what exactly does this help with? Like, is the extra information really more useful than just the standard old TV weather forecast?

It can be really useful for determining the microclimate. The landscaping & gardens in your yard can live or die from it.

Have you by any chance documented how you did this, or could you link me to where you learned how to set this up? This is actually one of the projects I puttered on for a long time with one of my RPis (NMEA-2000 to SignalK) but abandoned because I had too many moving parts.

Been meaning to blog about it, but not got around to it yet. Essentially it's just a (bunch of) USB-serial converters and the Seatalk data is converted by a Raymarine E85001. If you have N2k, you need a different converter, e.g. Actisense or better yet, a translator to NMEA0183, which is the de-facto standard for NMEA over TCP/IP.

Yup, I've got an ActiSense NGT-1 that outputs NMEA 2000 PGNs on USB Serial that I can decode with CanBoat: https://github.com/chrismetcalf/canboat-ansible

You can tell by the age of the repo that I got a bit distracted... the distraction just turned two years old.

2 Pis for dealing with ADS-B (airplane data), one for 1090Mhz, the other for 978Mhz. I could run that on the same one, but seemed easier to just split them up given some of the software is a bit picky with device IDs. The 978Mhz is much quieter than the 1090Mhz, so I also run a private SpyServer ( https://github.com/lloydpick/docker-spyserver ) for listening to radio transmissions. 1 Raspberry Pi for a running a very…

What do you use for receiving the radio traffice, something like an RTL-SDR, or something else?

Is it this? https://www.youtube.com/watch?v=yqgLaMc9IVA

No, but very similar! I made mine as a product you could attach to any board, as opposed to the strips being embedded and shaped into the board like the one in this video (which normally cost thousands to buy...) A few of my friends rode them at a contest in France though [1] Alas, at the moment it's just a kick-starter pipe dream I'll never have the time to put into production.

Those look way cool!

You are a kindred spirit. I have: 2 pi NTP servers - one running a GPS hat + PPS wired up, one using a USB gps receiver. a "workhorse" pi - 2 wired ds18b20 temperature sensors, cron jobs, email generators, weather page generator, connectivity monitor. One pi running piubos + nextcloud. One pi running as a clock. One pi running as a wireless temperature receiver. a few floating pis running media center or retropie or…

Maybe there should be a help group for people like us?

We need help. Possibly ways to acquire new models pis early, or get volume discounts.
