Makey Marble Machines

Page history last edited by Josh Burker 7 years, 1 month ago

This project challenges you to create a marble machine that successfully moves the marble from the top of the board to the bottom and does so while causing a connected computer to play notes from a song. You will use a combination of familiar parts and perhaps new to you technologies to accomplish this feat.

Gather

Materials:

- Makey Makey

- Marble Machine

- 10' cove moulding, cut to 1' lengths

- 30 x 5" pieces of 1/4" round dowel

- cardboard

- box cutter

- cutting mat

- conductive copper tape

- aluminum foil

- hookup wire

- wire cutters

- wire strippers

- scissors

- roller switches

- laptop

Construct

Implement a course of action

- Build an troubleshoot a marble machine until the marble consistently travels the course.

- Wire the ramps using a variety of methods.

- "Musicify" the ramps using Scratch.

Switch construction: conductive copper tape on ramps

- Two parallel strips of conductive copper tape make an effective switch when the marble, wrapped in aluminum foil, bridges the two strips and completes the circuit.

- If the marble is rolling too fast, the Makey Makey might not have time to register the connection.

Switch use: rocker switches

- You can use a pre-existing switch with the Makey Makey. Experiment with which pins from the switch need to be connected via alligator clips with the Earth and key pads on the Makey Makey.

- This switch is good for higher speed contact with the marble.
