So, like I stated in my last post, I went to get 50 1n4148 diodes - 3.00€. I already feel bad for not taking more of them. I am going to use most of them for my keyboard matrix of 30 buttons, which will be the input of my computer (it probably won't be the only one, since it would be cool to use the computer for processing other types of input data also (sensors maybe).

Bellow, you can see a few images of how the keyboard looks so far.
