UPS + Car Battery = More Computing (Or a 48 Hour Disco Ball?!?)
UPS Hack! Take the tiny battery out of your Uninteruptible Power Supply and replace it with a car battery: you get to run your UPS for a lot longer, and potentially melt your face!
Uninterruptible power supplies are a great for maintaining power to a PC during a black out or brown out.
Unfortunately most UPS's pack tiny batteries that last just a few minutes before they drain. That's great for saving out files and shutting down. It's not so good for working on and on while the power is out.
Quite a few of you have written in about using a car battery with your UPS... we don't recommend it, but we walk you thru the project in this episode!
