liscab, let me know your results with that mod.
I think I can build a 3.7 box mod but I don't know about a 5v mod....one extra step that I don't quite understand.
By the way, what do you pack your carts with?
I am only using the KR808d carts when I go out in my car or out for the night.
I bough some kind of filter for the bathroom air extractor it is not the best but it works, but the carts are so cheap ....
My new mod;I have a wall to usb 2000 ma with 5 volts output (2 indeed I always try to have 2 of every thing at less just in case)
( I rather use that to protect my comp. usb) I took and ubs cable removed the battery from my mod and soldered the cable to it, this a quit test I have to improve it but the olds atty really work better, I will never try a new atty on 5 volts.Now I have to work on a battery 5 volts mod, I hate to be wired, I got the regulator from radioshack I have to find the right box now, I let you know when ready
