Duh, my mistake. I was on a roll... But hey, you could plug these in between a UPS and a server!! that way the UPS could keep the little motor running, but not get sucked down by the server!! > >About the X10 controllers... Never heard about them before. How do >they work? What are they used for? It sounds interesting. You can get them at radio shack, fairly cheap. You can also get them via mail-order but that would be too late. Also, see www.x10.com for info. I bough a bunch of these years ago. They're pretty damn cheap now. You can probably find them at hardware stores, like HomeDepot, Builders Square, etc. The thing I didn't like about them is that they're too low tech. They send a signal across the power lines and there is NO collision detection. So if two units send a signal at exactly the same time, weird shit can happen, like if you and another person turn on or off different devices at the same time, a totally different device might activate/deactivate. And potentially, a neighbor's X10 appliances could be controlled from YOUR apartment, since the signal can travel quite far!! Unix systems measure "uptime" in years, Winblows measures it in minutes.
