 This is the tether cell, which really doesn't look like much more than a plastic sleeve, but in reality there's a full set of circuitry in here. There's Bluetooth 4.0, and then in here it fits a AAA battery and turns it into a AA battery. So the idea is you can put this in a device that takes a AA battery, and then you can do some cool things with control, because you have Bluetooth 4.0 access through the sleeve. This is going on Indiegogo next week. We don't have a price yet for the tiers, but hopefully we'll find out more soon.
