Ayla  and me decided to make "simple pinball switches" in a box

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.

Circuits:

1 ) R2 : 1 M ohm 2) R2: 10K ohm 3) R2: 100K ohm

1 - 2 : 0.1μF 1 - 2 : 0.1μF

3: 22 μF 3: 47μF
