From the site: What can you do with The Hammer? * Receive visual feedback for Kegel exercises or physical therapy * Have a lightsaber duel * Get a blowjob or handjob in the dark * Watch the Hammer change color as you orgasm * …or anything else you can program! Right now The Hammer has two modes: the test-your-strength game, where the more you squeeze, the more it lights up; and a demo mode which cycles through all of the colors of the LEDs. Soon I hope to connect the Arduino to my Android phone, and then I’ll be able to do even more cool things!
