Wow, a ton of great ideas. Big thanks to everyone.
VOLT - tried to find some data on this item, it looks like it might have a 510 threading from the pics. But then I found a few
reviews and they mentioned it is comparable to "other KR808" kits. So I'll need to dig deeper into the Volt for real answers.
COFFEE/INTERNET CAFE - Emailed a buddy on this one who knows about coffee brands, equipment, etc. Said he'll call me later with all the poop but in short sounds very doable from his notes.
IGO - Another puzzle about threading. Looks like 510 compatible but need the hard data so I contacted the manufacturer to see what the real story is on this one. Does look promising though, the batter comes in 3 lengths at 3 different mAh, just don't know the operation voltage.
We'll keep plugging away until we get the kinks worked out. Thanks again everyone.
So let's see, if we can get a few thousand people to all send Shannon65 a dollar, her store could be open in no time.
