Linux

damn you all, now I impulse bought an old thin client for 30EUR :-) but, fwiw: I mostly use RPi for my purposes, up to RPi4; RPi 5 I think missed the mark, with its active cooling requirement and power use. (and price...) the only use case where an i86 alternative is justified is my jellyfin setup (where realtime transcoding is needed).

And for some (including me) that's our only computer (other than phone). I just can't afford anything, so all I have is a shitty laptop from 2010 that barely plays 1080p video. I deeply want something better, especially a steam deck, but doesn't look like that'll happen anytime soon (or ever). And then you see people have steam decks that just sit there, unused, gathering dust.... fuck.

I mostly agree, and did the same with my second gen lab build - instead of shiny new NUCs like I had used round 1, I bought old off lease Dell Xeon boxes. SO MANY PROS -

• Got them up to 14c/28t each
• They can take GPUs and actually do heavy transcoding/ML work
• They can take up to like, 128GB of memory, which is GREAT when they're all hypervisors

The downsides can't be denied though -

• Even without the GPUs and beefed up CPUs, they are power hogs - the CPU alone uses more than an ENTIRE NUC
• They run HOT
• They run LOUD

The same holds true for off-lease SFF stuff, Lenovo and the likes ...

So while reuse/repurpose is absolutely of the utmost importance, no question - when it comes to technology and how quickly it advances and miniaturizes, a thorough and logical pros/cons list is often required.

I'd add another option though - if you do need what a Pi brings to the table - do you really need a shiny new Pi 5? Is it possible a used Pi 3 or Pi 4 would do the trick, and check the reuse box?

I would say it can sometimes be nice to have an old Laptop for this purpose, you have to slightly over build your solar but can be nice to have a mouse and keyboard attached and monitor, ssh works. Still have an hp laptop with a core i5 2nd gen sitting out in my greenhouse, is a little more power hungry but not terrible on idle, and is nice to be able to configure changes to watering without going back inside or wrecking the zen by bringing phone.

The day i can fit the power of a computer capable of emulating the switch 1 in a gameboy shell will be glorious.

The only caveat here is the fire-hazard non-removable lithium batteries.

The power constraints are more important to most than the size constraints honestly.

You lose the I/O and power efficiency is no comparison. You can get better power efficiency and sometimes some I/O with an old router and OpenWRT, but you'll be in the class of a Beagle Bone and a much harder learning curve. I've never managed to get a sensor or peripheral working on some old laptop's SPI or I2C buses like how easy it is on a Rπ.
