| − | == There are a few requirements ==
| |
| − | * The project needs to have a relation to your own practice.
| |
| − | * The circuit is part of the entire aesthetics and concept.
| |
| − | * For the final project there is no breadboarding allowed (you can use a breadboard for prototyping though)
| |
| − | * Remember your focus is to expand your toolbox, experiment and process is important. Document!
| |
| − | * Don't overcomplicate, you need to be able to explain what is going on.

| |
| − |
| |
| − | Although this ''homework'' may be a bit boring, it is fundamental to your understanding of electronic circuits. Look at it as a material study.
| |
| − | You can use a resistor calculator to help you with the resistor color code (See resources below)
| |
| − |
| |
| − | * Create a personal wiki page and link to it here. You will need to keep your progress and document your results on this page. See for an howto: http://opensource.wdka.nl/wiki/Wiki_Writing_Workshop
| |

| |
| − | == Circuit with one resistor ==
| |
| − | * Make a circuit with one battery and a resistor. Note the voltage of the battery and the resistance of the resistor.
| |
| − | * What is the voltage '''across''' the resistor
| |
| − | * What is the current '''through''' the resistor
| |
| − | * What happens to the current and voltage if you double the resistor value
| |
| − | * What happens to the current and voltage if you half the resistor value

| − | = Week 2 ''homework'' =
| |
| − | For this week you need to find and build a (small) circuit using the 555 timer.
| |
| − | * For this weeks homework it is fine to build the circuit on a breadboard and make sure it works.
| |
| − | * For bonus points use one of the other techniques we discussed, e.g. the dead bug style or the volumetric style.

| |
| − | Choose a simple circuit of which you understand what it is supposed to do and you think you can build. This most likely will be something with sound or blinking LEDs.

| − |
| |
| − | = Week 3 ''homework'' =
| |
| − | * Download and install [http://www.cadsoftusa.com CadSoft EAGLE]
| |
| − | * Download the EAGLE 555 blink template with schematic and PCB layer here: [[Media:Eagle_555_template.zip ]].
| |
| − | * The template contains all the components needed to create a simple 555 Astable circuit (aka a Blinking LED):
| |
| − | [[File:555_template_schematic.png|200px|thumb|left|555 blinking schematic]]
| |
| − | * Recreate the schematic on the left.
| |
| − | * Create the PCB layout
| |
| − | * '''Following the SparkFun tutorials on EAGLE (see resources below) will be VERY helpful along the way!!'''
| |
| − | * '''Don't not make your PCB larger than 3 x 3 cm (as in the template).'''
| |
| − | * '''Don't make your traces smaller than ~0.3mm (12mil)'''
| |
| − |
| |
| − | '''Note:'''
| |
| − | * You may use any other program (KiCad, gEDA or even Illustrator) to create the PCB layout but this is on your own account.
| |
| − | * You can create your own schematic instead of the template but you will need to figure out yourself where to find the components in the library (HINT: use the search option with wildcards (*) in Eagle).
| |
| − | * I will be providing enough components for everyone to build the template on a 3x3cm board. If you need other components let me know which ones or what size your board did become. However I can not guarantee they arrive in time.
| |
| − | * Remember this is an exercise in create a circuit from scratch not in designing the coolest gadget in town (that is what your project is for ;-).
