Yes! If this Kickstarter campaign is a successful, we have plans to release FloJacks in a variety of form factors... including phone cases. Once we get our 3D printer we'll be trying out some new designs. Stay tuned.
The FloJack runs on a standard 3V lithium cr2023 battery (included with each FloJack). You can find these at any grocery or convenience store. The FloJack is extremely power efficient. The consumption per polling interval is ~10uAs. On a 250mAh cr2032, this works out to about 90MM polls. At the polling rate of an Android device (10Hz), the FloJack would last just over 3 months. But since FloJack's sleep mode kicks in when apps stop using it, we estimate typical usage patterns will allow upwards of a year of battery life.
The Open FloJack SDK will include everything you need to build apps with the Flojack including: (1) FloJack Firmware Interface Docs (2) FloJack iOS Helpers (3) Code Samples, Tutorials, etc. We're hoping to empower developers to port FloJack to other platforms including Android.
The FloJack has been tested with third and fourth generation iPod Touch, iPhone 4, iPhone 4s, and iPhone 5. For other devices like the new iPad4 and iPad mini, we need to test it out but we’re almost positive the FloJack will work fine.
