Kevin (keegan11):

We made noise. Based on conductive copper, we used the sunglight, in more detail the UV light, to produce our circuit board. Accoringly we customized the basic circuit by just drawing things on the negative. After that we soldered the cuircit as illustrated in the image below.

Materials:
 * batteries
 * wires
 * LEDs
 * speaker
 * circuit
 * chip
 * etc.

Function: When the poles are connected sound (some would say noise) is produced, depending on the resistence that ouccurs between the poles.

Result:



Raphael (Carapace): 

The first project of the NanoHacking course was concerned with the modification of materials.

The preparation process:

1. In order to create a voice generating device we first used a template which we customized to give the board its individual layout.



2. Secondly we treated the board with UV light (Sunlight / UV device) to manipulate the first layer.



4. What is important to note is that in order to have a functioning circuit the board should not be too long in the sun.

5. Subsequently we treated the modified board with a chemical solution to bring our circuit to the surface.







NaOH = developer NaSO4 = caustic

The soldering process:

1. After the creation of the circuit we had to solder the essential components on the board. The following components were used in the process:
 * prepared board
 * chip
 * batteries
 * wires
 * LEDs
 * speaker





2. As a result of the soldering process we were able to create our own working device which is able to produce sound based on the resistance between the two poles at the back of the board.
