Software and hardware for Arduino-based orgasm prediction / detection


The case can be 3D printed without support material. Print at least the top half of the case in white to see the LED display beneath.


All the Gerber files are included to order a set of PCBs. The BOM is available on Octopart. The PCB has mostly surface-mount components, and is doable with either a soldering iron or solder paste.


The vibrator is made from a Mabuchi RS-555PH motor, with an eccentric mass pressed onto the shaft. These can be purchased pre-assembled, or built from the motor and some .88" to 1" diameter cylindrical brass stock. The vibrator case is compatible with attachments designed for the Hitachi Magic Wand. The motor is press-fit or glued into the two halves of the case.


This project uses a Teensy LC, which will require the teensyduino addon for the Arduino IDE, and its included encoder library. The detection algorithm uses a circular buffer for calculating a running average, available here.
