Hello all, I recently like many decided this will be my year to troop in a GB uniform for NYCC. Been a fan all my life and think the spirit pack is really an affordable /upgradable option. I have gotten the Alice frame/eBay light kit/v mount/stickers. I have been searching this forum for any links to what would be a good source for a rechargeable battery system (contained like an rc style) that I could have installed in the pack. I also have seen the word audrino used a lot has anyone have a link for how to use that to get some sounds going on that and what the normal cost is for something like that?
