Step 1: Step1 clean/dismantle
usually its very simple to take something apart,
the Darth Vader bank im hacking is held together with just 4 screws, which allows me access to the back of the battery tray
you dont want old battery acid all over your power leads so make sure its clean!!
Step 2: Step2 strip USB
carefully unsheathe the wires, there will be 4 of them. the black and red wires are the power. and the other two are for information. we only need the power wires.
connect the black USB power wire to the Black power wire from the device. wrap with electrical tape.
and likewise with the red
Step 4: This is another thing i made run on USB
i use it on my moniter that has a USB power port that comes on with the moniter which i use to power my lights
its easy try it!
if it does, reassemble and your done!
i youtubed a video of my test
hope this helps!
keep on hacking!
