Create voice-controlled power outlets with Raspberry Pi

Trying to use voice recognition with embedded electronics has always been a painful or expensive affair, however with the advent of the inexpensive Raspberry Pi computer - it can take care of the heavy lifting for the voice, and also take care of controlling the electronics. As an example of this, Ben Finio has created a system that allows for voice control of power outlets.

By using hacked wireless remote control outlets, no mains wiring is required. Instead the remote has been hacked to have Raspberry Pi-controlled relays press the buttons when required. The voice recognition is handled by a part of the PiAUISuite (Pi Alternative User Interface Suite) that uses a microphone for input. Finally, a quick demonstration is shown in the following video:d

That's really neat, and we love the voice response back to the user as well. For complete instructions, check out the system Instructable. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.

If you're making a similar project and need to control large currents with your Arduino digital outputs - you'll need a MOSFET. We've got you covered with out NDRIVE: N-MOSFET driver/output module:

This high-power N-MOSFET module lets you switch high-current loads using a tiny microcontroller. Perfect for controlling that set of traffic lights mounted in your living room! Works brilliantly for automotive projects such as switching high-power 12V lights and high wattage LEDs. For more information and to order, visit the product page.
