Thanks for the share! 🙂
Maybe just recycle them, they are way too out dated.
“Outdated”? They’re Raspberry Pis, jeepers. You’re not expecting to run Crysis on them.
I have a little home data center and all the computers in it are 5 to 10 years old. They work fine as servers.
Outdated in terms of rpi4 or even rpi3. A 5 to 10 years x86 maybe is still working fine (I am running a home lab with 1st gen Xeon). but the first generation of rpi is way too slow to run most application, due to ram and io limitations.
I ran nextcloud on gentoo on my original rpi. The stories of their inadequate resources to be useful are greatly exaggerated
I mean, my gen 1 or whatever works great for a shell server (SOCKS proxy, IRC client, webhook callback testing) and random other stuff, like hanging a CO2 logger off of. It also used to host a Jabber chat service, although I now have that running on a different machine for reasons unrelated to performance.
There’s already enough of a problem with electronic waste. Unless the power draw difference is massive (10x?) then there’s no reason to get a new computer for basic stuff like this.
I’m super curious why you have a CO2 logger at home?
I think I originally bought it because I’d seen these studies on the impact of CO2 concentration on human cognition, suggesting that long meetings at work in closed meeting rooms literally made people stupider by the end of the meeting. (I’m still not convinced this is a thing.) And it turned out that I could get a USB CO2 meter for reasonably cheap on craigslist, so I bought one from a little old lady who had used it for her cannabis grow room.
It turned out that the office CO2 levels were quite good, only about 600 ppm, even in the conference rooms. My home, though, was around 1000 ppm, rising up to 2000 or even 3000 ppm in a closed bedroom overnight (with two adults). I used the 1000 ppm, the floor area, and the outdoor CO2 levels (450-ish) to calculate the air exchange rate for the main living area, which came out to… I actually don’t recall exactly, but it might have been 1/3 turnover per hour. Less than I thought.
Most recently I’ve hooked up the meter to my rpi in the basement and set up a logger script using https://github.com/heinemml/CO2Meter to see what it’s like down there. The basement tends to be fairly warm in winter, probably due to the boilers and pipes for the steam radiators, and it has occurred to me that it might be a nice place to set up a workstation that isn’t in my bedroom during these work-from-home times. The levels down there are shockingly low, around 500 ppm – there aren’t people breathing all over the place, but I guess it also means the boilers and hot water tanks are vented properly. (I would expect it to be colder if it were just due to the air exchange rate.) If the radon levels look good, it might be a good option for a workspace.
That’s nice, yet every board out there is not designed to be easily tested and repaired.
