Duggle Posted January 8, 2005 Report Share Posted January 8, 2005 I agree, my first thought is to beware of noise introduced by the motor drive!Remember that this project has been devised and successfully implemented for non audio application, rather DAW automation (optically isolated midi etc). For example the H bridge clamping diodes are mounted on the pcb, but where localised noise could be an issue, I would mount them directly across the motor with capacitor bypassed Power supply lines so that the back-emf current spikes are not carried through wiring close to sensitive audio circuitry (yuk!). I'm not saying what youre aiming for can't be done (it clearly can) just do lots of prototyping ( and proper testing) before you commit to a major project.good luck Quote Link to comment Share on other sites More sharing options...
