At Arse Elektronika 2012 this fall, I’ll be presenting a Test Your Strength game! This is the first electronics project I’ve ever done outside of a class: a silicone toy consisting of a bulb instrumented with a force sensor and a shaft containing a row of LEDs. The bulb is inserted either into a vagina, or potentially into an anus. When the person squeezes, the cock illuminates. The harder you squeeze, the brighter it gets.
Because who doesn’t want a light-up cock?
There are lots of interesting possibilities for this project: Visual feedback for Kegel exercises would be really helpful. Watching the cock change color as the wearer had an orgasm could be fun. So could receiving a blowjob or handjob in the dark, watching your partner’s face lit only by the glow of your shaft.
At this point I don’t have the whole toy assembled, but I’ve put together a proof-of-concept.
Eventually, the final product will be based off of the Feeldoe insertable strap-on (strap-in?). Right now, I have two silicone bulbs: one bulb contains a pressure sensor which reports its data back to an Arduino; the other bulb contains two LED pixels which can be controlled by the Arduino. I’ve tested the sensor and verified that, yes, it is possible to get useful sensor data and control a set of LEDs with my vagina. All that’s remaining for the final toy is to get everything into the same piece of silicone and deal with a few calibration/smoothing issues.
I have until the end of September to get this device finished. My stretch goals are to have 3 copies of the toy and a phone app that will allow for easy calibration. I’d also like to add an accelerometer, so that as you move the cock around the app would make light saber noises.
Thanks to Jimmie Rogers for showing me how to hook up the force sensor to my breadboard correctly! I’m using an Arduino Duemilanove from Adafruit Industries (and anxiously awaiting them to restock their beautiful-looking accelerometer modules).
I’ll be posting updates here as I make more progress on the device. If you’d like to see the prototype in person and you’re in the Boston area, I’ll be showing it off at the next teasecraft-boston meetup (July 20, 7:30pm-9:30pm, Artisan’s Asylum Classroom, 10 Tyler St, Somerville, MA.)
