2014-08-08 (F) Arduino Powered Tattoo Machine Controller

A different tap was procured. A tap handle was selected instead of an electric drill. The #43 hole cut previously was fully tapped. A macro shot was taken to show the clean tap threads and the broken tap in the first hole. The dashpot was secured by tightening a nut over a lock washer onto the armature bar. The electrical, which is usually attached to the front binding post and contact screw, was connected to the chassis via a stainless steel bolt holding the new bracket. The tattoo machine was connected to the tattoo machine controller. The system was activated at a range of frequencies but no good movement was seen. The magnets were operating but insufficiently to to pull the armature bar. A replacement armature bar was ordered.
