I already gave it away (pics at http://www.aleyfun.com/2009/10/20/diy-5v-power-supply/). My first hot glue case and it turned out quite well to my standards. The hardest part was trying to solder the wires to a bit of 2pin header. I didn't have a third hand so I ended up using 6 pins of header before I got it right. It used to be a mini USB charger for a cell phone so I would assume a fairly stable voltage.
