Here's something useful you can do with an obsolete Android phone. http://androidthermostat.com/
Android Thermostat is an open source thermostat project ideal for programmers and electronics hobbyists. As the name suggests the application runs on Android phone that is connected to some basic electronic components for controlling your home HVAC system.It costs around $140 to build and can be assembled in an afternoon. That $130 price includes $40 for a used phone. The rest of the cost goes to building and packaging the circuitry to interface to the thermostat lines from your furnace. It's built on Sparkfun's IOIO (pronounced "yo-yo") interface board, at $50 the single most expensive item in the project. It "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." Basically a micro on a perf board with some canned code to do PWM and other I/O stuff. -Tom _______________________________________________ Hardwarehacking mailing list Hardwarehacking@blu.org http://lists.blu.org/mailman/listinfo/hardwarehacking
