Hello everybody, thanks for having such an informative website.
I have a diy project that I’d appreciate some help with. I recently purchased an LED Bike light (http://www.dx.com/p/zhaoyao-bicycle-t6-led-flashlight-headlight-headlamp-usb-rechargeable-mountain-bike-light-red-488150#.WkoBqWxOn5A) which is powered by USB (the cable end is a male usb, and it is suggested to have 3.6V and 3A).
I would like to turn this into a stationary style short range spot light which I could hook up to a 110V outlet. Although the unit has modes, I would also like the ability to wire in a dimmer to be able to adjust brightness.
How would I go about hooking this up to an outlet? I am thinking of using a cell phone charger (2.5A and 5V). Would this work? And any idea on how to add a dimmer and what kind?
TIA
