More on gamepads

Song found a few other options that looked good. However, in the end they didn't have what we wanted in a controller. This sparked us to keep looking. We ended up back at our first two choices. We're going to schedule another trip back out to see them to make our final purchasing decision.

Spent the rest of the day determining how we will power the AR viewer. Looked at different battery packs and discussed how much power we'd need, how we'd connect it, house it, charge it, etc. The thought occurred we could use a standard laptop battery and we could swap these out with Song's G4 battery, but this may have connectivity issues as well as management issues (i.e. is the other battery charged, where's the laptop to charge it, etc.). Stephen is leaning toward a barebones battery pack for cheap and having a few for swapping out and charging. Song said she'd try to find a suitable connector for the laptop battery before we make a decision.
