3:00: Tools, Processes, and Materials

Labs:

Use the Electronics basics page and its links. Use information posted in Slack #electronics channel.

1. Use the resistor color code.
2. Use the multimeter in Voltage, resistance, and continuity modes.
3. Build a voltage divider circuit. Build a potentiometer circuit.
4. Build and measure circuits with resistors in parallel and series.

Work on kinetic sculpture assignment.

Assignment:

Some good precedents include Sophie's flock of birds, Kassia's dancers, Chris's Geneva drive, and Megan's bird. Some examples of kinetic sculptures made with common household supplies can be seen from last summer's course, especially Silvia's clever use of string, Michelle's method of making circular cams, and Avi's automatic highlighter.

Resources:

Modeling gears in Fusion360 from scratch is a useful exercise. But you can also use a script to help automate the process. The first half of this video shows you how.
Look up artists like Arthur Ganson and others. These pieces probably took more than a few days to complete, but likely many of them started with study models made from things like cardboard and simple DC motors.
Here is a fun old reference for mechanisms: 507 Mechanical Movements, and offshoots.
Rob's example of using simple materials and joining in a prototype. And some extremely rapid prototypes
