Anyone on or near Auckland's North Shore got a Pi 3 they're looking to get rid of, name a price? The one I use for Flightaware has just fried itself, and the software won't run on a 4. There's some places that still sell 3s, but they're both asking fairly unrealistic prices for them and it's unlikely to arrive any time soon, or at least in time to avoid killing my uptime score on F-A.

Several places have stock, but see above, they're asking very high prices (>= Pi 4) for a superseded model, and it won't get here for another 1-2 weeks. For example Nicegear don't reopen until 6 Jan, and that's only when the order will be processed, not when it arrives. I was checking to see if anyone has an old 3 lying around they'd be interested in selling. There's one on TM with a Flirc case and other stuff I don't need, but that'll take a week to get here too.

Seems flightaware need to sort their software out then I guess? Why doesnt it work on Pi 4? Not just a case of installing a few extras libraries?

Then you can grab one from PB right away

Edit: yep looks really simple....

That can be a bit of a one-way process, I can't find the thread any more but Flightaware push out updates from time to time and there were reports of them breaking custom installs on Pi 4s when the updates went out, so it works initially and then goes downhill over time. Having maintained a custom kernel build for another Pi-based device that the original devs abandoned in the past I have a strong motivation towards going with the off-the-shelf config that the herd is using rather than branching out with something special. It's just risk-aversion after having been burned in the past.

I think I might have one lying around, but I won't be available to look it out until next week. PM me Monday if you're still looking.

Thanks! Got a lead on a 3B that I might be able to grab, otherwise I'll ping on Monday.

Element 14 have them: https://nz.element14.com/c/embedded-computers-education-maker-boards/raspberry-pi/embedded-single-board-computers-sbc-raspberry-pi?product-range=raspberry-pi-3-model-bpos

Just say you're a company though 🤫

Doesn't affect anything. Can still get delivered to a home address.

Alternative approach: Buy me a Raspberry Pi 4 (and power adapter) and I'll swap you a 3B.

Already checked there, their prices are always reasonable and I need to get some other stuff from them anyway, but in this case they're backordered and the claimed lead time is six months. Not quite sure I believe that, but it's still not encouraging.

In any case I have two possible leads, so fingers crossed will have one soon.

Got a surplus 3B which is being dropped off tomorrow, naturally it's the day after Flightaware announce "PiAware v3.8.0 released in the next few days which will provide support for the Raspberry Pi 4". It doesn't really matter though, you don't need the minimal extra features on the 4 so the surplus 3 is fine. Thanks to everyone who replied.
