Freezer backup power that won't make a stink?

My employers are looking into obtaining some sort of emergency backup power for a couple of specific, large appliances. Assuming gas generators are not an option, what would a person use to provide a couple hours of power for, say, a freezer capable of pulling 15 amps when the compressor turns on? [more inside]

Power supply requirements for external blu-ray drive

powering video card in a new computer

I bought a new computer and realized that the power supply does not have a dedicated six pin cable for my video card. It does, however, have two sata cables coming from it (like this) that are situated in reserve for an extra bay device and also an extra hard drive. Can I use an adapter to sufficient convert them as a power source for a six pin Radeon HD 6850? If so, would it require a converter for both sata connections, or just one?

I think I need a UPS? If so, which one?

When the heater in my place (convector) cycles off, my TV goes black for a second or two. I worry a lot about what this is doing to all of the electronics using outlets in the same wall as the convector. Do you think I need a UPS, and can you guide me through the process? Details inside!

New power supply for old lego motors

I have a bunch of old Lego 71427 motors (seen here) and a battery pack (I believe part 5293) that was stored for a decade with the batteries inside, with predictable results. Easiest way to make these usable, short of tracking down the long-discontinued original battery pack? [more inside]

Do I need a new computer power supply, or can I fix this one?

I have a 650W power supply in my computer that I installed myself back when I asked this question (scroll through the answers on that for most system specs). This morning, the fan on the power supply started making noise. Do I need to replace the supply entirely, or is this something I can fix on my own? [more inside]

I'll put this over here, with the rest of the fire.

I replaced a PSU and have received the original, cheap so-called 500W power supply. It has a dead fan. Works great except for the fan; cleaning didn't revive it. I don't own a desktop computer. Makers, hackers, what fun can I have with this PSU? What should I read to bring me up to speed? [more inside]

Pinout for this ancient xenon arc lamp power supply?

Recently I obtained (for work-related use) an older arc lamp power supply. It's a Zeiss unit brand-wise but was manufactured by Ludl Electronic Products (LEP) on Zeiss' behalf. It may well turn out that this particular supply isn't suited to our needs (based on the lamp we want to use it with), but I would still like to find some way to determine the pinout of the output connector. Unfortunately, I've had a heck of a time finding ANY schematics for 75 W DC xenon short arc lamp power supplies, and despite my EE degree, I remain baffled following *mumble* weeks worth of ohming-out and circuit-tracing. And at this point I've been staring at the darned thing so long that it's become hard to tell if I'm missing something really obvious or whether it's just futile to expect to be able to determine what pin serves what purpose without a schematic. Long, convoluted explanation beyond the "more inside" button. [more inside]

Help me bring my crappy keyboard back to life!

I'm trying to resurrect an old Casio CPS-85 88 key keyboard. When it was given to me, the power jack was cracked, so I desoldered it and soldered on a new one. No luck; I can't get power (even with a different power supply). So I'm stuck running off of a lot of D batteries. As using D cells is both wasteful and expensive.is there any way for me to rig an external power supply to the battery terminals in a safe manner?
