[Joyce Hinterding, Aura, 2009] In week 4’s workshop, we delve into the world of electronics. Why? You may ask. We find out how electronics have been used as a medium by contemporary artists. We add this tool to your tool box by beginning with the basics into electronics.
Discussion: RGM Post-mortem
Let’s quickly review the RGM class exercise.
- What works well?
- Is there anything that surprised you?
- What require more time/ effort?
- Can you give an example of the most important thing you learnt about working with materials? What materials did not work as you thought?
Discussion: electronics for artists
[Kim Williams, Account Payable (detail), 1998]
Research: electronics for artists
Research one of the following artworks:
- Ken Rinaldo Autopoiesis http://kenrinaldo.com/
- Joyce Hinterding Aura http://www.voltashow.com/Joyce-Hinterding.6932.0.html
- Simon Ingram Painting Assemblages http://www.gowlangsfordgallery.co.nz/artists/simoningram/
- Kate Turnbull, Modern Vanitas http://www.katieturnbull.com/Modern-Vanitas
Present to class and answer these questions:
- Describe the work.
- How is electronics used/ function in the work? Is it an essential part of the work in terms of its function, concept, or both?
- What is the audience’s experience?
- What may be the thoughts generated from this interaction?
- What is your appraisal of the work?
Part 1: Mechanical flashing bulb
In a group of 2, create a circuit that conducts electricity using the 12B graphite, paper, clips, and LEDs.
Now, make the light bulb flash … using any mechanical mean you can think of. Draw a picture of how you will make the light bulb flash.
More about circuits
Use a multimeter to measure the voltage, current, and resistance in your graphite circuit. Can you vary the resistance?
Current (I): the flow of electrons, measured in Ampere (A)
Potential or Voltage (E or sometimes V): the electric potential difference between two points, measured in Volts (V)
Resistance (R): force in opposition to the flow of current, measured in Ohms (Ω)
Things to remember:
- Electrons flow from the negative terminal to the positive terminal.
- An electric circuit is composed of electronic components connected by conductive wires.
- A closed circuit allows the current to flow.
- An open circuit is a broken circuit that interrupts the electric flow.
Demonstration: How to use a multimeter
- How to use a multimeter?
- When to use a multimeter?
- Why would need to use a multimeter?
Research and present:
- What are the following circuits?
- What do they do?
- What are they used for?
- What do they look like?
- Circuit in series
- Circuits in parallel
- Series-parallel circuit
Part 2: Electronic flashing bulb
Electricity is a flow of electric charge (electrons). Electricity in nature: static electricity, lightning, electric pulses in the body etc.
[Russian scientist Georg Richmann was killed by the electric charge of lightning while repeating Benjamin Franklin’s experiment]
Electricity can kill! NEVER TINKER WITH 240V!! Follow Safety protocols! For this subject, do not hack into devices that use 240V electricity. If you incorporate a 240V device in your project work, this device must be tagged by UOW. (We will organise a tagging session for any of these devices).
Build a simple circuit: flashing light bulb using electronic comonents
In a group of 2, building the following circuit. First, you may need to research which component is signified by which graphic.
Research and present: Components
What are these components used for? What are their diagram symbols?
- Resistors (including variable resistors)
- Coils/ Transformers
Research and present:
What do the following terms mean?
- Direct Current (DC)
- Alternating Current (AC)
Part 3: Digital flashing bulb
Using an Arduino, create a flashing bulb that is identical to your analog flashing bulb, but control it digitally.
What are the differences between a mechanically flashing bulb, an electronically flashing bulb, and a digitally flashing bulb?
Project work: Ideas mapping and Concept mapping
- Begin to think about ideas for project work in this subject. Will you be able to use electronics in your project?
- Draw an idea map of your project (map of the central idea you will explore).
- Draw a conceptual map of your project (a system map of how related ideas, materials, processes are connected to each other).
- Discuss your project proposal with you tutor.
