Arduino-controlled pelvic-floor strength-tester, with light-up penis

Last September, Doctor Kristen Stubbs -- a roboticist who makes sex-gadgets for her Toymaker Project -- released a video (NSFW) demonstrating her prototype pelvic-floor strength-tester, called "The Hammer." The Hammer has a bulb that is internally inserted, containing a squeeze-sensor, and a penis-shaped, light-up readout that protrudes between the wearer's legs. The harder the wearer squeezes, the more the readout lights up.
