Control Arduino Projects with Your Voice and an Android Phone

Voice recognition is a one of the best ways to control Arduino projects, but it's not exactly easy to implement on your own. Instructables user ASCAS shows off how to add voice control to your Arduino projects using your Android phone and Bluetooth.

The Arduino gets a Bluetooth attachment and a set of code. Then you'll need Android Meets Robots, an app that lets you pair voice recognition with any Bluetooth module. From there, it's just about pairing the two together and creating your own commands.

Scientists make deep-brain implants possible through wireless charging

Stanford researchers have figured out a way to wirelessly charge electronic devices that are deep inside your body. Currently pacemakers and nerve transmitters need to have large receiving coils near the top of your skin to charge up (limiting where you can put them), or periodically have their battery replaced through surgery. This new method, however, would allow devices to be much smaller because they don't have to tote around such a huge battery. Also since they're not reliant on charging coils they could live much deeper in the body and brain.
