Homebrew PCBs

Jean-Claude

Thank you for your kind comments.  Must go and use it for an add on PCB I am making to add feedback to a cheap ebay triac lamp dimmer so that the motor speed does not vary with load.  Drives either permanent magnet DC or universal motors. 2 diodes, two resistors, a capacitor and a pot is all that is needed.
I will add it to YouTube when finished.

               Before a friend ham wanted to throw it to the
 scrapyard,
 
               I could get
 
               a hold on it. The needed trafos for the
 spindle motor
 
               and the bulbs
 
               were just hanging around so I made an aluminum
 case to
 
               hold them.
 
               The spindle height lever automatically
 switches the
 
               spindle on as
 
               soon as lowered. May be someone gets some
 ideas to make
 
               his own.
