I'm going to be installing my Arduino attic fan controller in the near future. The project was put on the back burner so I could address other X10 issues, but now that those are dealt with and proven reliable, it's time to get the fan going again. In any case, i will be putting the controller in the attic and plugging it into an AC outlet for power. I was originally going to use an old cell phone charger, but after learning about X10 PLC noise issues, I won't be using a switching type. A quick search on ebay and Amazon found only switching power adapters. Does anyone have a line on a cheap power adapter for the arduino that is non-switching?
Requirements: 9 to 12V DC, 250mA or more, 2.1mm plug, center pin positive.
