So, apparantly thunder struck down in the area I live in, I had pulled out all the equiepment from the outlets, except for my router because I forgot. Should I be worried something might have been damaged or would it have shown by now? The router is connected to a switch and two computers. Everythning seems to be working fine but im kinda worried since the ligthning apparantly broke stuff for other people. Also do surge protectors really work if lighning strucks? Maybe I should consider buying some.

Consider upgrading your electrical service panel so that it protects your house from surges.

Surge protectors are fine but they wear out. The service panel upgrade is really expensive but you can get your insurance to help mitigate it

a decent UPS is great for stable power, but rarely is it actually "CLEAN" power. it'll probably even tell you on the back that it's output has an amount of harmonic distortion to it.

if what you plug in has its own switching power supply (smaller AC adapter [not the larger heavy ones that use a transformer], computer, etc), then it should be fine, but anything that actually requires a proper 60hz/50hz sine-wave like an AC motor or something might suffer.

here's a guy talking technical about the UPS mention here >>22144 I believe:

tl;dr
need need actual clean power? have to get an actual line conditioner.

Back-UPS models work the way he describes.

Smart-UPS models always run off the battery. Think line conditioner on steroids.

The downside is that if your power company is shit you will end up replacing the batteries every couple years, because every power event gets either sent to or pulled from the battery.

The upside is they're lead acid batteries that can be bought everywhere and not just from APC. Find a local battery store and the likelihood is they'll either have your battery in stock or you can special order it for 50% or less of what APC would charge.

Hey, /sci/. I'm running a simulation of solar panel efficiency and I need some way to calculate energy production from the sun's position in the sky. For example, assuming a panel that is always pointer at the sun, when the sun is closer to the horizon the panel will generate less energy than when it's high in the sky.

I'm looking for something like f(x radians) = y W/m^2.

Thanks.

Sorry to hear that. Try moving to a less shitty latitude?

You could try to find a climatic compromise, for example. Suppose you get solar panels power supply in summer and traditional electricity in winter. How about that? As for house darkness you can get to newmarket window replacement https://thwindowsdoors.com/newmarket-window-replacement/ and change your small old windows to multiple new ones. This will attract some extra light, I assume.

My Chink laser accidentally turned itself on in my coat and burned a hole clean through but the worst part is the lens cracked and I need to replace it but I cant budge it out of the cap housing.

Need reliable tutorials on how to get it out.

Hey so I’ve been feeling weird pains in the left side of my chest and I’m concerned it has something to do with my heart but I’ve had anxiety about heart problems since I was little ever since in school we watched a health film where someone gets a heart attack and so ever since then I’ve had a fear of heart attacks and I’m 19 years old so when I brought up my concerns to my doctor he told me that it was probably just my anxiety but Jesus fuck I’m still kinda nervous.

What do I do?

An philosophical consideration of economics and governance.

bros, fiat currency be built upon complex bureaucratic/technical systemS and crapto all the more so. And, any material stores of wealth are subject to depletion and/or entropy (natural or/and anthropomorphic)... and if dat shit ain't food, it's intrinsic value rests solely upon faith that it can be exchanged for food.

Which brings us to the importance of stable/rational good-faith actors of semi-at-least competence, /wise/ if you're given to idealism (wild,、 should you subscribe to cynicism in the modern mode)~

bros before hoes, but sometimes bros can be hoes, in the infidelity/treasury sense, so ya know, trust and discernment

not to be condescending, but don't worry about being a man (or anything really)~ enjoy existence, be mindful of friends, family/community and enjoy what you have while you have it and, if so inclined, do what you can to improve the lot of humanity as a whole

I mean it's fine to dissect it if you were on good terms and AT LEAST FUCKING TOOK CARE OF IT. But neglecting it and then lwk desecrating (or what could be interpreted as) it's body is a bit much don't you think? It's not like you were some buddies and it would totally get it ykwim?

You did your part as much as you could, ultimately failed at it and let that be that bro. Leave the little critter to rot in the ground.
