Sensor to Detect Device Removal

I’ve been watching this space for some time. My wife and I have dabbled in Male Chastity intermittently over the last few years. A consistent annoyance for us both is how easily ball devices can slip out. We’ve tested different ways to secure them, but usually comfort suffers as a result. Then it hit me: instead of focusing on security, what about accountability? It would let my wife know if I’d messed with or taken off the device.

So far, I’m looking at using an AT42QT1011 capacitive touch sensor mounted to the exterior of the penis tube. An Arduino microcontroller drives this sensor, monitoring it continuously. It tracks how long since installation and logs any loss of contact with the penis onto a microSD card, noting both when the disconnect happened and for how long. The electronics—currently powered by a 9V battery along with the controller and reader—are going into a locking waterproof enclosure roughly the size of playing cards, suitable for belt wear. I’ve validated the concept using an Arduino Uno R3, a Catamex Card Reader, that AT42QT1011 sensor, and custom code. Be careful choosing your sensor; some models like the 1010 recalibrate after about a minute if they sense continuous touch. All necessary components run under $25.

There’s more work ahead. We could shrink it down with an Arduino Nano or Trinket. I’m still deciding on the best way to mount the sensor, ideally integrating it directly into the tube. The enclosure design needs refinement too.

It’s been enjoyable sorting this out. Perhaps a manufacturer will see this and get inspired. Once I have a functional prototype, I’ll update everyone.
