  This is what the board looks like once assembled
  
  Note: Pot value selected is 50K, if you have a preference for another value please find the same model with that different value. The timer frequency cap is labeled as ".1uF*" on the board. Again, select one of a another value if you have another preference.
  
  A spacer should be placed between the tact and board to give it a proper height. Laser cut delrin spacers will be included. (http://i.imgur.com/RVEMTEs.png)
