Do you intend setting up/using the serial comms of the UPS freezer?

The serial port I only used once for configuration. I don't need monitoring, as I only need to monitor the battery voltage.

Ah ok. Our UPS's in work have the software installed and configured to alert the pc to a power loss and to shutdown. The UPS then holds the supply for a couple of minutes or so before turning off (once the pc has, of course).

Guess you don't really need that facility!

Hehe, nope. And PC shut down can't be disabled in this software, meaning that the UPS, designed for a 7Ah battery (and reads voltages a good .4V too low), reads as if it had two minutes of runtime left.

Freezer, you have my respect man, being 15 years old and being able to do build that says a lot about you and you will prolly do well in life but it also says two other things about you.

1. Your house will burn down one day

2. You need a girl friend

or you'll electrocute yourself... and yes you do need a girlfriend or another fucking hobby - collect some stamps for fucks sake or plant a garden

and another question - where do you live that you're preparing for a 3 day power outage and did you already dig out a fallout shelter



and +1 for your crazy skills

Stamps and gardens are gay. This is a men's hobby!

Yet another upgrade has come upon my beautiful system! After a very successful advert in the local newspaper, I have here, from the local newspaper (lol), a 750W Smart-UPS from 2005 (old one from 1998 ). They had somehow managed to explode the batteries in it, how they did it is beyond me. Not that it matters, as the UPS itself is still working like new. And, well, it is new. The logs in it show that it had been plugged in for two months in 2006, and two days before I got it.

Not only is it 2-3 times as powerful as my old one, it is also 10-15% more effective, provides me with a clean sine wave output as opposed to the jagged on my old UPS, can support a hell of a lot more load, and runs on 24V, so I don't have to think of my cables burning up or my batteries equalizing (series vs parallel, if parallel, they'll charge/discharge each other during an hour or two until they're on the same voltage)

The black beauty:


Awesomeness in a box.


The left side. There used to be a black Smart Slot there, but I fucked it in favour of better cooling and more space for wiring.


Extended cooling on the transistors, made up of the heatsink from an old 7300LE. These eight transistors produce less heat than the four on my old one. Talk about difference in efficiency!


The batteries were hooked up with a nice little adapter, which makes for an awesome connector to connect the external batteries. Way more practical to just plug the batteries from the UPS rather than having to disconnect the batteries and fuck around with the cable as soon as I have to move the thing.

I Also be 15 since last Friday, and if given the opportunity, I would very probably do the same thing, problem is is that Freezer, somehow, has access to a fucktonne more computer crap than me(Srsly, where do you get it all?)
But yeah, I'm not about to go Dumpster diving for OLD computers(people only really trash the 5+ year old ones with like P1s), and I don't have any techie inclined friends IRL that can give me their old gear.
Best example: I'm planning on spending ~$50 to BUY a very used 1.4ish Ghz "server" from the local computer recycler.


But yeah, I have an Arduino, and I play with electronics, and I understand computers inside and out, but I just don't know where to score gear, liek where'd you manage to score 2 UPC's(You said 2, didn't you?)

[/jealousy]


That aside, are they Deep-Discharge batteries? Or are you just not going to kill em all the way?

And are you planning on plugging the UPS into yer compie for monitoring and control?

And drill a hole in the UPS case >.< that bulge is pissing me off.

Nowmore (unfortunately), I get most of my stuff from advertising in the local newspaper. There's this fucking recycling facility that won't let you take stuff anymore.

And these batteries are hybrids, or so-called boat batteries; They're not just as good as deep-cycles, but they can take a good 30-40% discharge without any damage. Plus, I won't exactly be going down to 10V on a daily basis. The UPS shuts off when they reach about 11V. They were also so cheap that it doesn't really matter.

I also got two other UPSes together with this one (One identical to my 420W and one 650W Back-UPS from 1992, with an awesome power switch, but I gave those to a mate, cause he helps me out with a lot of tech-related things, and also has an interest in stuff like this.

Totally odd, i can never see any pics freezer posts

I can, fine.

Maybe you add blocked his photobucket site?

I've blocked jamesys avatar. lol

The batteries tend to blow themselves up all by themselves, so don't feel too down hearted

We have aprrox 10 batteries sitting in our maintenance area waiting to go into APC UPS's that have shit themselves.

I don't mean that usual little corrosion that's inevitable on this kind of battery, but I mean almost-blown-to-bits-exploded. She said it went out with a loud bang.

How did the unit survive with, what looks to be, no internal damage?

Thankfully not. The batteries APC ships have a blow-protection shell. The battery pack was basically round and white instead of black and cubic.

So it didn't actually "blow up" then?

Well it blew up like a balloon, but didn't explode?

It went boom, but the explosion was contained.

Kinda like when you fart in bed, the "explosion" is contained under the covers

that is until you force your GF head under there

Then comes the slam to the face.

But it sure is a "MAN'S KIND OF POWER SUPPLY"

Wadayamean "not practical"? I can carry it all at once, especially now with the battery plug

And what is practical, if being 100% shielded from both surges, brownouts and blackouts?

I was looking at the first pics only my bad man,What I meant by not practical is thinking of having two ginormous car batteries on your desk in your room.

They're sexy.

Is this the part where we start worrying?

Nah, rather we ready our cameras
