In my Masters of Educational Technology program at Michigan State we had the opportunity to host a Maker Faire. We broke up into groups and each group designed a maker “station”. Our group created a human drum kit and it turned out awesome! I want to share a “how-to” for building a human drum kit.
Purpose: The purpose of this activity is to leverage the power of a Makey Makey and Scratch programming to create a set up where one person in a group is a drummer, and each of the other people in the group are part of the drum kit (snare, cymbals, etc.). When the “drummer” touches the hand of the person connected to the snare wire it will complete the circuit causing the snare sound (in Scratch) to play. If you have a person for each part of the drum kit you will then have a fully operational drum set (made of people).
- Makey Makey
- Several Alligator clips and connecting wires
- Conductive thread (This has two uses, first it is sewn into the “drummers” head band, second it extends the connections between the Makey Makey and the parts of the drum kit.)
- Pipe Cleaners (To create the bracelets that parts of the drum kit will wear.)
- Copper Tape (To wrap around the pipe cleaners, so that the wristbands are conductive.)
- A computer with working speakers that is running this Scratch Program
For the set up I will be referencing the diagram below. The blue dotted lines represent conductive thread connected to wristbands (pipe cleaners wrapped in copper tape) which must be touching human skin. The red dotted line is conductive thread connected from the “earth” part of the Makey Makey to a headband. The headband had conductive thread woven into it. The thread must be touching the forehead (skin). With the scratch program running on the computer a person only needs to touch the drummer for that instrument to sound. This completes the circuit which sends the signal to the computer.
A special note about the kick drum: You can use a wrist band and a person for the kick drum. We found that it worked better if we attached the blue kick drum wire to copper tape on the floor. Then when the drummer touched it with their bare foot they completed the circuit for the kick drum. This allowed for the kick drum to feel more natural. (You could also connect the blue wire to tin foil and wrap it around the person’s shoe if you didn’t want to go barefoot.)
Here are a few suggestions after having been through the project. First, tape down the wires. This keeps them much more organized. Second, make sure there are many points of contact for the headband. Third, make sure no wires are touching the headband wire. This unintentionally completes the circuit. Last, make sure that the copper on the wristbands has a good contact with human skin. Without that you can’t complete the circuit.
Below are a few images and videos of the drum kit in action. If you have any questions at all please leave a comment or tweet me and I’d be happy to point you in the right direction.
