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. | |||
