              the resistor              
 it resists electricity.  it can  be good 
 or  bad  at  this and  this  property is 
  measured in ohms. resistors practice  
   aposematism, showing with colours how  
           dangerous they are.            
             the capacitor              
 this   is  an  ephemeral   battery   and 
     voltage multiplier, used for load    
        balancing and for defence.        
             the lodestone              
 stores  a  position  in a magnetic field 
    and outputs electricity when moving   
        closer or further from it.        
           the schottky diode           
 this   component   limits  the  flow  of 
 electricity through itself to go in  one 
             direction only.              
           the mustelid probe           
     measures distance to (uncloaked)     
              the cat wire              
 a  wire  used to  connect  machines  and 
         appliances to each other.        
               the slower               
 slows  down  the operation  of a circuit 
               the furnace              
   exports daemon energy through. some    
               kind of hole               
 not  covered:  water  circuits  (see  my 
 post  on  submerging a  magic  spell  in 
 water   for   details   about   how   to 
              implement them)
