Exploring options for prototyping new device via Android environment as first step.
Description from SparkFun: The IOIO (pronounced “yo-yo”) is a board specially designed to work with your Android 1.5 and later device. The board provides robust connectivity to an Android device via a USB or Bluetooth connection and is fully controllable from within an Android application using a simple and intuitive Java API – no embedded programming or external programmer will ever be needed!
Sparkfun says the board’s now discontinued. Continuing to investigate an interim fast prototype approach.
