The February, 2011 issue of Nuts and Volts magazine has a very
interesting article, "Build A Wall Wart Power Monitor", by David
Goodsell which is on page 42. The device allows you to check voltage and
current for common wall wart power supplies. This might be useful to
your Gumstix projects.
I just ordered all the parts for this. I can say that the J3 part from
Mouser is backordered till late March.
