**This exercise is done partially since we do not have any fab  lab machines here at fab lab addis**  According to the specification given during the conference, I  made a schematic drawing of a circuit by making use of Eagle software. we where suppose to add some additional component to the circute design given to us, so I added a switch to my circute design. The drawing  is shown on the figures/pictures below.  
 picture showing the schematic drawing of the circute drawing   After making the schematic drawing of the circuit board, I move  on to making the board look realistic in the board media of the eagle software.  And the fallowing drawing was the outcome.
   
   After the board diagram is prepared like shown in the above  picture, I prepared additional two drawings: one for the body of the board  and another for the boarder     
 
   Board drawing ready  for machining of body and boarder line of the circut board. As shown in the picture above, I made four holes at four  corners assuming that the board will be screwed to other components.          |
