After searching for references and inspiration, I've decided to design a paper circuit. Using The great big guide to paper circuits, I will create a typograhic poster with conductive tape or conductive ink (working with conductive carbon graphite powder is also possible, but probably less practical to attach components). I'm also planning to play around with LEDs and lights in the circuit/poster. I have in mind not only to experiment with form and typography, but also with circuits. Thus, I can unite my major (graphic design) with this practice (digital craft) in this project.
Main inspirations
I've came up with this idea after finding an image of conductive tape folded in a circuit, which reminds me the New Alphabet of Wim Crouwel [1], a Dutch graphic designer, type designer, and typographer know for his experiments on typography and readability. My plan is to design the circuit and the typeface with LEDs on it. I still have to came up with a sentence or a word for the poster.
- From 1964 onwards, Crouwel was responsible for the design of the posters, catalogues and exhibitions of the Stedelijk Museum in Amsterdam. In 1967 he designed the typeface New Alphabet, a design that embraces the limitations of the cathode ray tube technology used by early data display screens and phototypesetting equipment, thus only containing horizontal and vertical strokes.

Homework 02 | To find and build a (small) circuit using the 555 timer
A Circuit that flashes an LED on and off. [[8]]
↳ This circuit uses the 555 timer in an Astable operating mode which generates a continuous output via Pin 3 in the form of a square wave. This turns the LED (D1) on and off. The speed at which the LED (D1) is turned on and off is set by the values of R1 and R2.
Parts lists
1x - NE555 Bipolar Timer
1x - LED (Red)
1x - 470K Resistor (1/4W)
2x - 1K Resistor (1/4W)
1x - 1μF Electrolytic Capacitor (16V)
1x - 9V Voltage Battery
Comments and observations
- Smaller resistors led into faster flashing lights.
- To add more LEDs, it is needed to create a "bridge" (using wire).
- More LEDs will use more of the battery. You need to check out the value of the battery before adding LEDs. Adding LEDs to the circuit may overload the 555 Timer. In order to avoid it, it should be add more resistors in the circuit.
Homework 03 | Recreating schematic layout
1. Download and install CadSoft EAGLE
2. Download the EAGLE 555 blink template with schematic and PCB layer here: Media:Eagle_555_template.zip .
3. The template contains all the components needed to create a simple 555 Astable circuit (aka a Blinking LED)
4. Create the PCB layout
5. Following the SparkFun tutorials on EAGLE (see resources below) will be VERY helpful along the way!!
6. Don't not make your PCB larger than 3 x 3 cm (as in the template).
7. Don't make your traces smaller than ~0.3mm (12mil)
