You probably don’t want to physically cut the power to the PC. It should be fine to do that (modern software and file systems are quite resilient to power outages), but it can still cause issues. So I would suggest using some software implementation rather than a straight up power switch.
My personal Mastodon instance is doing great. It runs on my old gaming desktop in my living room. Haven’t had any downtime today, so I can say with 100% confidence that my living room has better 24 hour uptime than Amazon right now. Who wants to buy some compute time from my living room?
Yes, so, basically what I said. Be careful and understand what you need.
If you’re thinking from the mind of someone who understands current, of course you wouldn’t use 26 awg wire for speakers. When you’re giving advice online though, you have to think from the mind of someone who doesn’t have your same knowledge. OP telling someone “just use a vacuum cleaner power cable” isn’t specific enough, because they don’t have the knowledge OP has to understand what that means.
I completely agree with OP that speaker wire is generally a rip off, and using any suitable wire is fine. I just want OP to also say that you need to know what you’re doing, or you could start a fire.
I’ll give you an anecdote to hopefully illustrate my point. A while ago I was hanging out in a friend’s backyard on a chilly night. She wanted to provide some warmth for the guests, so she brought out two space heaters and a power strip. She plugged them in and turned them on and they ran for about 30 seconds, and the circuit breaker tripped. She went over to it and flipped it back on, and then about 30 seconds later it tripped again.
I’m not saying this to disparage her, but to illustrate that many people don’t understand current, and don’t realize what is and isn’t dangerous when it comes to electricity. It wasn’t unreasonable for her to assume that would work, and it wasn’t unreasonable for her not to understand why it wasn’t. The breaker is there for exactly that reason. When you’re talking about making your own wire, it’s too easy to get it wrong if you don’t know what you’re doing, and that could cause a fire.
Mass. Whatever. :P
