Title: remove dc motor noise from audio circuit
Post by: Dj Task Manager on May 14, 2014, 08:11:13 AM
helloooo,

im building a mechanical sequencer thingy that you program by slicing paper!  Its rad and it seems to be working.  The issue i have is there is noise from the motor getting into the audio.  is there anyway of blocking it?  Probably some sort of filtering with capacitors right?

here are a couple of photos(http://2.bp.blogspot.com/-MHtJaIygwRo/U3MWYRE7kuI/AAAAAAAAAYc/aUuErIpIvDE/s1600/P1030081.JPG)
