How to build your own UPS

It's public knowledge that South Africa's sole electric company is battling to keep up with demand. You only have to look at my UPS performance summary to appreciate the amount of brownouts we experience in our area of Margate.

Sometimes the brownouts last up to eight hours or more. As a result, I have collected all manner of uninterruptible power supplies which are linked to all the computers scattered around my house. This ensures I’m not left in the dark halfway through a game or a spreadsheet I spent the last hour compiling. Those of you who have experienced this know how infuriating power loss can be.
