First thing that comes to mind is ye olde cheap opamp and a potentiometer. This aritcle claims hysteresis can be done with a resistor. Opamp output is not meant for relay, but it can control a transistor which in turn can control your relay just fine.
Edit: i’ve just re-read your post, there’s no need for relays if you have low voltage, just get a transistor rated for more than 5V and make sure it wom’t overheat.
Cloud and “serverless” solutions
for chat there’s IRC or bit more modern XMPP.
It’s more likely to be a sb like me who just gathers stuff like that for future use in (maybe) questionable way.
I use TinyBit launcher, i think it can do it but i never needed to because junk app quickly go so far in list you just don’t see them.
You need optimus or bumblebee to do that. Just beware those are pain to install.
Asimov’s Foundation series (two times polish translation and once original) and The Hitchikerms Guide to Galaxy by Adams Douglas (once in polish, twice original)
Try to shine strong flaslight trough it, if you’ll see traces of wire it’s a RFID/NFC sticker. Those are used for identification.
Guess you should go search for more Laura’s songs.Ii love her voice too!
Lux Æterna by Metallica
Temperatures would be okay in the twilight zone, not sure about water, but winds would blow you out of your shoes.
“nil” or “null”
Same! I would also cram a small server and ton of tools into it so i would have a portable hackerspace.
You would be pumping your server heat into mass of water and just swapping it from time to time with cold water from lake/sea/river/whatever.
It’s called The Internet afaik.
Just be sure those pallets were not used with toxic stuff. I’m damn sure that those that lay behind food stores are just ok.
I use xss(.)is for unique tech stuff.
What about servicing those turbines so they don’t fail at all? “This dam powers our city since 4000 years.” Sounds nice and Star Trek-ish doesn’t it?
It wouldn’t need to be AI, just sone statistics and “Crdiac arrest? Piority 9. Broken arm? piority 1” decision-making.
I’m a tech wizard not a healer, there probably are factors that define one cardiac arrest even more critical than the other i just do not know them.
Ppl do it with UV LEDs and they claim it works. I never tested it, i’m dried-a-cactus kind of guy.
