+Ayla  and me decided to make "simple pinball switches" in a box
+We went through some trash bins on the campus and found some thicker cardboard
+boxes, probably used by architecture students. We also found some conductive
+materials that were our six obstacles aka our six switches. Between the two
+cardboard boxes we put two breadboards that were creating five sounds. With the
+help of some alligator clips we connected every obstacle on the inner side with
+some copper wire to the breadboards.

+So each obstacle was one part of the switch. The circuit was closed when the ball
+that was wrapped in aluminium foil touched the positive and the negative part of
+the obstacle.

+Because the speakers were inside the box, the sounds were a bit silent so we made
+some holes on the sides of the box and also some smaller ones on the board itself.

+While building we realized that it's always that you have to think about how to attach something to another part, make it stiff or make it flexible, also.
+Inside the machine, we worked with five 555 timers in two different breadboards.
+The main constructions was the same but the values were varying in relation to different values of the resistors between the pins 6-7 and 7-8 and the capacitors between pins 1-2 and 3.
