@tag16c my driver is just a full bridge that driving with a PWM. I'm using 4 FDS8858 (half bridge drivers) to create 2 full bridges. Each of the FDS8858 has a 2n7000 that allows the gate voltage on the FDS8858 to swing up to whatever the V+ is that I drive the coils with. Right now I'm driving them with 6V. @Spelljammer I experimented with making the hinges more flexible. I tried lengthby timogiles - Polar Machines, SCARA, Robot Arms
I've been working on a single mirror galvanometer design also. I just put my design up on thingiverse and I figured I'd share with you guys. http://www.thingiverse.com/thing:179041. It's a work in progress but I'm making pretty good headway on it. I've ditched driving it straight from a headphone jack, if I'm going to build a printer based on this method i'd rather have it dedicated to a micrby timogiles - Polar Machines, SCARA, Robot Arms
