I have a USB ventilator, that I want to use while i'm soldering to bring some fresh air to my atelier. I don't want to have my computer there to do it. So I was thinking to connect it to a 5v regulator and connect it direct to AC. I google around but didn't find any diagram or project that I could use as base. Basically I want to have something like:
AC -> Switch On/off -> 5v Regulator USB Port -> GRD.
any idea, links, etc?
Links to buy iphone charger isn't what i'm looking for. I would accept it if at least, the iphone charger have an on/off switch
