Bill's book is actually worth buying from a projector builder's standpoint. It neatly bridges the empty gap between what you'd find on the web/in data sheets about Galvos and the point where you would have to start reading highly technical engineering papers or dig into some really old literature. Not too technical, the explanations are crisp, supported with good illustration, and the math is kept to the absolute minimum. While It does cover Galvo wiring, I would have added a chapter on sizing and selecting power supplies for Galvo amplifiers.
