2014-08-21 (Th) Arduino Powered Tattoo Machine Controller

A short video was recorded which showed a blue 12VDC light being dimmed and brightened by chaning the duty cycle. Since it was standard speed video and an incandescent light the change in frequency could not be observed. An LED and motion would have revealed a segmented path with different size line segments as the duty cycle and frequency changed. The full range of light dimming proves the duty cycle adjustment works but does not prove anything about frequency changes.

Testing 12VDC light with tattoo machine

To do:
  • Chart speeds with dampener 
  • Revise code 
  • Retest with dashpot? 
  • Debug code 
  • Get tattoo
