Suggestions for creating an audio controlled vibrator

Hello everyone, I’m looking for some help turning my toys into audio-controlled vibrators, similar to how the ohmibod works. Right now I have three basic vibrating items that need this upgrade: an inflatable buttplug, a dildo, and an egg. They all run on two AA batteries each and use an analog rotary dial to adjust power… I want to take audio from either a computer or a Hi-Fi receiver and convert it so the toys respond with vibration. For instance, loud sounds at high frequencies should cause fast, intense vibrations… Lower frequency tones would result in slower, gentler pulses… Does anyone have suggestions? I’m really eager for some guidance on this. I’ve been tinkering around for a bit but haven’t managed to get it working or find much information. The only thing I could locate is: … ett-oh.htm :arrow: My electronics knowledge is basic (to put it mildly) :arrow: I have plenty of cables, switches, and similar components :arrow: I can solder I’d really appreciate any feedback. I’m sure many people would find this idea interesting… Best regards, Bound Soul
