oh so you did try a 555 timer? im just waiting on a freind or when my dad buys a new ban saw blade so i can cut my hdd's down to size so i can mount them and once i do ill have to start playing around with it. did you set each disk lens holder mabob as left and right speakers like both ground to negative and then each one acting as a different speaker channel? and when you say the oscillition wasnt big enough do you mean not high enough of a frequency?

Well, my circuit had a big frequency range, but even at the lowest, the oscillation wasn't powerful enough. I used a stereo system, so the "galvos" had unique channels.


@Flaminpyro and rangedunits

Thanks!
