I planned to create an unfunctional PCB-design using the tools and aesthetics of a classic PCB. I decided to only use angles of 90 and 45 degrees to create patterns. I started working in ''KICAD'' and using ''PCBnew'' to create different patterns. Being able to rotate and mirror the copper tracks was a huge help to get big and consistent patterns faster. After looking at some PCBs that i found at home and holding them in front of a computer screen, I saw that light can shine through the PCBs if there is no copper in the area where the light is trying to pass. This creates shadows the viewer can see from the other side. So I decided to use this feature of the PCBs for my artistic approach and tried to apply shadows to give some threedimensional character to the picture I was creating.

'' A picture of the PCB with sunlight going through. ''

To increase this effect I edited the mask layer on the backsite of the PCB so, that there is only mask left where I wanted to place shadows on the front. Like this the light can shine through better. Knowing that these shadows would only appear if there is light shining through the backside of the PCB, I wanted to create another PCB with LEDs on it to make a backlight. Of course this PCB would have the same size as the other because I wanted to put it inside a frame, so the backlighting PCB would not be seen. I created another PCB and used ''ledcalculator.net'' for the scheme I had to use with the number of LEDs i wanted to use.

[[File:pcbdokupic2.png|400px]]

I put the LEDs in even distances next to another so the light would shine through equally on all the areas of the frontplate. When it came to ordering the PCBs I found out it was not as cheap as I thought. I ended up only ordering the frontplate as I had some LEDs at home and wanted to build the backlight myself. The next step was to build a frame for the picture. I had problems to adjust the size of the single elements of the frame as I did not have the right tools to measure distance precisely and cut the wood in 45° angles at the same time. Using a little more woodglue to fill the resulting gaps between the angles holds the frame together pretty good. From this point on I experimented with some LEDs and found out that the frame was too small in depth to create an even backlighting inside the frame. The LEDs would always be too close to the frontplate and created areas with too much light in comparison to the other areas. Using some kind of paper between the LEDs and the frontplate would have helped a lot with that problem, but i sadly did not have enough space inside the frame. Therefore I decided not to use LEDs for backlighting the first prototype, as I also found out sunlight is much more beautifull when it shines through the frontplate and also gives a different view on the picture depending on the position of the sun. Yet I still want to create another version with consistent LED backlighting, but for that I need to build a bigger frame. I will update the wiki when I have done so. The ''KICAD'' projects can be found on ''Github''. https://github.com/erk4ns/kicadpcbarts

==Description==

[[File:eeschema.png|thumb]]
[[File:pcbnew.png|thumb]]
[[File:3dview.png|thumb]]

There is hardly an industrial process which is as optimized and streamlined yet customizable and complex as printed circuit board (PCB) production. At the same time it is highly accessible to anyone from electronic engineers to hobbyists, enthusiasts or artists thanks to very competitive and affordable prices and easy to use tools. Production files can be uploaded online for instant quotes. On submission customers can get real-time updates on the production process.

In the class ''PCB Arts'' we will explore printed circuit boards as a medium for artistic expression and will discuss and realize individual projects based on this investigation.

While doing so we will acquire an intermediate knowledge of the involved processes and learn how to use free software for schematic and PCB layout creation.

Electrical functionality isn't a requirement for the result. The processes can also be utilized to create graphical works or the PCB can be a negative for relief printing processes.

This class will '''not''' cover the individual development of advanced circuitry, so you should either find an accompanying class (Recommendation: [[IFD:Analog Circuits and Interfaces WS20 21|Analog Circuits and Interfaces]]) for electronics or resort to existing and proven schematics.

===German description===
Kaum ein industrieller Prozess ist so optimiert und perfektioniert, und dabei individualisierbar und komplex wie die Produktion von Leiterplatten. Gleichzeitig ist dieser Prozess für jeden zugänglich, ob Eletroniker*in oder Hobbyist*in, Enthusiast*in oder Künstler*in - dank einem starken Wettbewerb, erschwinglichen Preisen und einfach nutzbaren Werkzeugen. Die Dateien für die Produktion können hochgeladen werden um ein sofortiges Angebot zu erhalten. Nach dem Bezahlen kann der Kunde in Echtzeit den Produktionsverlauf nachverfolgen.

Im Kurs PCB Arts werden Leiterplatten als ein Medium für künstlerischen Ausdruck erforscht und individuelle Projekte auf der Basis dieser Erkenntnisse realisiert.

Dabei werden wir fortgeschrittenes Basiswissen über die Prozesse erwerben und lernen wie freie Software zum Erstellen von Schaltplänen und Platinenlayout verwendet wird.

Elektrische funktionen sind keine Bedingungen für das Resultat. Der Herstellungsprozess für Leiterplatten kann auch dafür verwendet werden umd grafische Ergebnisse zu erzielen oder die Leiterplatte kann zu einem Stempel für Druckprozesse werden.

In diesem Kurs können keine komplexen individuellen Schaltpläne entwickeln. Es ist ratsam hierfür einen Elektronik-Kurs (Empfehlung: [[IFD:Analog Circuits and Interfaces WS20 21|Analog Circuits and Interfaces]]) zu besuchen oder auf existierende Schaltpläne zurückzugreifen.
