We introduce the Double-Oh, a custom-built battery allowing wireless control of any device that uses AA batteries. 'Buck,' the pseudonymous 31-year-old maker living in Berlin, posted to Twitter about it.
He demonstrated his device by connecting the Double-Oh vibrator to a Twitter poll.
"Here we go: my open-source Wi-Fi vibrator is in my butt again,"he wrote. "Vibration intensity is controlled by the poll. Liking the tweet means 10 more seconds of vibration. Retweeting means 30 more seconds of vibration."
