Is there any way to modify the electrovibe to run from an 18V power Pack and by pass the Charge pump? I saw another circuit for a vibe that had this option. I was wondering if it were possible with the electrovibe? After trying so many charge pumps and power supplies, I still get an annoying noise. I can get it to a low volume with a certain combination of charge pump and power supply but it is always there in one way or another! I believe if I can bypass the charge pump and run it from 18v, it SHOULD eliminate the noise?
