what UPS do you use ? I made my own

The cantered readouts trigger me a little.
But otherwise, pretty cool, how much did it cost in all to put together, and exactly what did you use?
>>54603105
it's the first version, so later on I might improve the visual aspect
about 1k everything included, to back up all my networking devices, a couple servers and the phone at home
>>54603134
might add that I plan to make a web management tool for it, probably running with an arduino or rpi.

> 1k everything included
I got a 750VA clean sine wave ups for $20 from a flea market. Dropped in new batteries, has full monitoring over USB. Can add more batteries with the anderson connector on the back.

it's not pure sinewave for 20$
APC BR1500G
It just works
Gives me ~30 minutes of idle power for my 2 2560x1440p monitors, my speakers, and my PC, roughly 15-20 minutes of power if I am gaming.

no?
>>54604379
It just says it's online, not pure sinewave.
>>54605051
nvm I'm blind, but still I'm suspicious because any decent pure sw inverter is $$$
who /cyberpower/ here?
>>54603069
Where's a good place to get them cheap?
>>54605093
CyberPower makes the best UPSes. I haven't had any problems with them, and I'm 5 years strong. Haven't replaced the batteries in any of mine and I'm still getting the full-rated time from open package.
My computer runs off of an internal battery if it gets unplugged, can run for around eight hours
Fucking cavemen

Are used UPSs trustworthy? What should I inspect? I'll see some at the thrift stores for cheap. I figure I need to replace the batteries, but wonder what else I should look out for since it's an electrical item that'll be plugged in constantly.

I like you, OP. Some are content to start off with the mildest of house fires, say from a flaky power supply of GPU. But you, you clearly have grander visions than that. You want to take it the extra mile, and loop in both stored masses of energy, as well as caustic chemicals. You make us all pretty proud, and I'm sure I speak for many of us who will chalk up your Viking funeral to that brave pioneering spirit.

I'm running two of their pure sine wave units. Rock solid. The battery in one lasted 5 years before I replaced it.
>work upgraded all their UPSes and were giving them away
>just need new batteries
feels good to get an smt1500 for next to nothing
>>54603069
building a DIY UPS isn't hard. making one so it won't catch on fire and explode is the hard part.

Where'd you get the etching for that panel done?
