Unsatisfied with an off-the-shelf product, Micah Elizabeth Scott (aka Beth) did what any experienced DIYer would do: hack it and rebuild it to her liking. While some use their modding skills to create custom video game controllers or Kinect-powered trashcans, Beth took her expertise to the bedroom. In an extremely in-depth and technical write-up, Beth tells a tale full of reverse engineering, ultrasonic tranducers, and an Arduino Pro Mini, all in the name of creating her perfect vibrator. To see the entire process broken down and a video of her masterpiece in action, head over to the source (which is free of vulgar language and pornographic images, but obviously includes photos and footage of the device).
