Knolled Object: NYT Electronic Crossword and Sudoku

Knolled New York Times Electronic Crossword and Sudoku 

 We were asked to obtain an electronic object to take apart and examine the input, processing and output parts. The object I took apart was the New York Times Electronic Crossword and Sudoku.

I then arranged the parts of the electronic devices by input, output and processing pieces.

We were then asked to point out 4 interesting parts of the device.

1 - Buttons and Key Matrix (input): As you press down on the button, it applies pressure on a switch on the key matrix. When the switch is pressed, it completes the circuit and a current is able to flow through.

2 - Circuit Board (processing): The processor compares the information gathered from the key matrix to it’s character map.

3 - Speaker (output) The speaker is one of the 2 main outputs of the device. It looks like an 8 bit speaker that you find on a greeting card. The device makes a sound when a certain input is detected

4- Screen (output) The screen is the main output of the screen. Once a button is pressed, the processor activates the appropriate segments on the display.
