Contents
Project
* Find or design a project / circuit to build * build it * modify / adapt it * document
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. * A written reflection document including documentation of your circuit.
Inspiration
* Stan Wannet, Logica / 0 * Tristan Perich, 1-Bit Symphony * Tristan Perich, Drawing Machine * Peter Vogel, The sound of shadows * Tom Verbruggen, Crackle Canvas * Tom Verbruggen, Module #2 * Jerobeam Fenderson, Oscilloscope Music * Jerobeam Fenderson, Khrang * Aram Bartholl, On
Techniques
* Circuits, dead bug style * Volumetric circuits (related to the dead bug style) * Wire wrapping * Parallax breadboard tutorial * PCB making, Toner transfer method * PCB making, etching * PCB making, fab house
Week 1 homework
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
Circuit with two series resistors
* Make a circuit with one battery and two resistors in series. Note the voltage of the battery and the resistances of the resistors. * What is the voltage across each resistor * What is the current through each resistor * What happens to the current and voltage if you double the resistor value of one resistor * What happens to the current and voltage if you half the resistor value of one resistor
Circuit with three or more series resistors
* Do the same for three or more resistors in series
Circuit with two parallel resistors
* Make a circuit with one battery and two resistors in parallel. Note the voltage of the battery and the resistances of the resistors. * What is the voltage across each resistor * What is the current through each resistor * What happens to the current and voltage if you double the resistor value of one resistor * What happens to the current and voltage if you half the resistor value of one resistor
Circuit with three or more parallel resistors
* Do the same for three or more resistors in parallel
Extra: Circuit with resistor and LED
* Make a circuit with a 9V battery, a 470 Ohm resistor and an LED. * What happens when you use a higher value resistor, how high can you go, what happens? * What happens when you use a lower value resistor, how low can you go, what happens?
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.
A good primer on the 555 timer: https://www.youtube.com/watch?v=SX01x1z7fTY 555 timer circuits:
* http://www.555-timer-circuits.com/ * http://www.talkingelectronics.com/projects/50%20-%20555%20Circuits/50%20-%20555%20Circuits.html * http://electronicsclub.info/555timer.htm * https://duckduckgo.com/?q=555+circuits
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
