ASSIGNMENT I - IMPROBABLE SWICHT


Pinballswich1.jpg

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.

ASSIGNMENT II - CONCEPTUAL SENSOR


Sensor.jpg

On this one I was touch to open the pin 6 and 7 on Astable Mode in 555Timer and play with, plus that with a serie of 555Timer Circuit we are able to modulate the sounds better. So I worked on my circuit and have decided to work with 3 555Timers connected. The first circuit was used light sensors and the second was used graffiti on a paper as a sensor table.

On the first circuit from the pin 6 was opened 2 channel where different resistors was connected with the LDR and after connected with pin 7.

On the second circuit, was opened 3 channels where each one also had a different resistor value connected with the paper.

The values are:


The result is that the variations of sound was even greater than the expected cause know was able to work with 5 variables.
