Voice Search for desktop is nifty and all, but what it's really been lacking is a worthy way to trigger it into action. The Verbalizer is an open-source dev board made specifically to be used with the search giant's new tools from up to ten meters away. This microphone-shaped piece of circuitry was made with Arduino compatibility in mind, which means that voice search is just the beginning. The company (who happens to be the same folks behind the brilliant Instaprint) will be distributing schematics and source code through its website, and promises to give away a "limited run" of kits for free in a drawing starting today. Head on over to the source link if you feel like testing your luck, but not before checking after the break for one more shot of these mini masterpieces on display as well as the nitty gritty PR.
