You can get a foot pedal from many old scrap sewing machines. I have used these in the past when I want to have a variable outlet. Hook the pedal feeding an outlet and you have a portable variable control outlet. Just make sure not to plug anything into it that can't handle low voltage.
Here is one on E-bay that has the outlet already. http://www.ebay.com/itm/universal-ho...item3a6b01d17a
I am sure there are cheaper ones. That is the first one that i saw.
