Audience
• Syllabus• Freshman Liberal Studies Colloquium
– No prerequisites– Somewhat self-selecting– Lab/lecture– Small class size – Writing intensive– Does not fulfill a major requirement

What’s Circuit Bending?
• The deliberate short circuiting of electronic toys or instruments
• http://www.youtube.com/watch?v=Wy1mdLpy0SY (father of circuit bending Reed Ghazala, 1:50-5:00)
– Random sounds– Circuit exploration– Sound found object art– Example: We are Records Circuit Bent

Why a Circuit Bending Assignment?
• Good fit for freshman liberal studies course: exemplifies interdisciplinary connections.
• Exploration of circuits will [hopefully] motivate some students to achieve a level of competency with basic electronics, multimeter, soldering…

Assignment Idea
• Buy a CHEAP, BATTERY-OPERATED, USED electronic toy or instrument.
• During two classes:– Bend.
• Explore the circuitry.• Mark interesting new short circuits.• Replace existing resistors with variable resistors.• Bypass capacitors.
– In case you destroy your toy, team up with someone who hasn’t destroyed their toy.

Assignment Idea
• Write a one page expository entry on your favorite musician who uses bent instruments or is classified as a futurist. What is your favorite recording? Why? Please link to a clip of that recording. Explain why you think her/his/their work is significant.

Pros and Cons
• Unpredictable• Students may/will
learn to solder.• Fun
• Unpredictable• Might trash the
speaker, board…• Might not have
interesting bends.• Solder burns
