i'm trying to build a sort of Ebow Organ. I've got a single string prototype up and running, and i'm trying to figure out how to accomplish a few things. Primarily, I'm trying to figure out a non-mechanical way to stop the string from vibrating after the driver is turned off. Right now, my plan is to send a DC voltage to the driver. Theoretically i see no reason why this wouldn't work, and i've had success stopping the string by bringing a small rare-earth magnet near to it while it's vibrating. However, i haven't been able to do the same thing electromagnetically. The driver coil's resistance is around 7.5 ohms. Is this a workable solution? if so, how much current or voltage should i be sending through the coil (or at least, what would be a good starting point)?
