Notes for 2022-09-14.
Assignments¶
Current assignment, due next Monday: Exercise: Actuated Marble Run Tile
In general, when uploading a video or zip file, please include your name or Andrew ID in the title since I often download them and it helps me track the files.
Administrative¶
Discussion of Children’s School visits on Fall 2022 Calendar: Wed Sep 28, Mon Nov 7, Mon Dec 5.
Discussion of final show: Fri Dec 2.
Agenda¶
Broader discussion of using marbles as a form for exploring mechanisms and kinetic systems. Following are a collection of structures to consider:
energy input
wheel lifts: adding potential energy back into a system
helical Archimedes screw
conveyor belts and wheels
centrifugal launchers: adding kinetic energy into a system
transport: moving objects from place to place
linear track
spiral tracks and bowls: reducing entropy
turntables: randomizing outputs, distribution
pin grids: randomizing, absorbing energy
ball sumps, system exit paths
minimum-time ramps (https://www.youtube.com/watch?v=1BdO8J0iynY)
logic and state
accumulators: counting, clustering
flip/flops and counters: mechanical logic
moving gates: mechanical and electrical logic, switching
Turing machines
optical sensors: electronic interface
weigh scales: electronic interface
mechanical NAND gates
ball delay line
ball sorters
mechanical outputs
ball overshot wheel
ball turbine
ball-driven mirrors, lighting effects
sound and noise
sound-producing pins
bells
sound-producing strings
human interface
direct ball input
flippers
launcher controls
movable gates
Videos
Sketch session
please draw your actuated tile ideas on the whiteboard tables
share with your table partner
I’ll rotate through the room
some questions:
Will it work?
Will it compose with other tiles?
Will it work in different orientations?
