Tests with voice-detection

In an earlier post I presented a capsule-shaped gag . This shape offers a few (minor) advantages to the ubiquitous ball gag. Even though this capsule gag is only a stepwise improvement over the ball gag, long journey often starts with a few small steps. A side effect of the lengthened shape of the gag is that it has sufficient space for a set of batteries and a blinking LED. I like the blinking LED as a trick on its own, because it makes the gag appear more playful: less of a restraint, more of a fashion attribute. That said, the real reason I put a LED in a gag, is that I wanted to experiment with a voice detection circuit. The ultimate goal is to either block or discourage the person using his or her voice. The first step is detecting it, and that has now experimentally been implemented. The half-ball of the gag unscrews, giving access to 2 AAA-batteries and a small circuit board. The circuit has to MEMS microphones, one at each end, and a microcontroller. The microcontroller right n
