My bubble hat goes through AA batteries really quickly, so I want to attach an external battery. It takes 8 AA batteries, and I generally have to replace them about twice per hour. It also has a hole for a 9V 15W DC power plug, which I assume you can use instead of the batteries.
I'd like to plug it into a ginormous battery pack. I clearly need the plug, the cable to connect that to the battery, the battery and something between the plug and the battery (whose name I forgot) if the electricity coming out of the battery isn't exactly what I want. I wouldn't be surprised if I need something else too.
Could someone give me an idea of where to start looking for components? I'm particularly clueless about what sort of battery to get. I'm pretty sure I can assemble it once I figure out what parts I want.
