Heya.
Okay short story, I'm more of a machinist who likes to TRY mess around with electronics so I need a little help with a project.
I've got a little paraffin lamp I've converted to a USB light using a 3w super bright LED. Basic set up is the light, switch and a 3x 1.2v 2700 mAh batteries. I want to be able to wire up a USB cable to charge the little thing so I can plug it into a cells charger plug(the USB connection ones) or computer/laptop USB.
Anyone got a diagram they could help out with please. Another thought is considering the little switch I have has a no/nc and com should I use that to limit the system to only charge while the light it Off?
Thanks much in advance.
Gordon.
