mario theme played on stepper motors with an arduino
Bookmarked 747 weeks ago now that i039ve figured out how to store song information in flash memory on the arduino i can actually play full songs this is a little suite of mario brothers themes that i put together enjoythe sound you039re hearing is coming entirely from the motors the song information is taken from a midi file that i composed an arduino provides the necessary commands to spin the motors at the required frequenciesnote: see my earlier video at http:wwwyoutubecomwatchv=8l8hy8siumqmotor 2 buzzed a bit on the table this time i039m going to find a better way to hold the motors still while still allowing them to vibrate---------------------------------answers to common questions:q: will you give me the computer code you useda: apparently i will because everyone seems to think i039m asshole for not wanting to ask for the code and i039ll be happy to email you a copyq: where are the other videosa: sorry i am quite busy with my phd work and don039t have an enormous amount of free time i promise to get around to these videos in the next few months by the end of the summer at the latestq: what hardware did you usea: the stepper motors are bipolar nema 17 motors the microcontroller is the arduino deumilanove the power supply is 24 v 4 amp i am also using a 3-axis stepper motor driver board manufactured by xylotex xylotexcom i actually don039t recommend the xylotex board anymore instead try the drivers available at probotixcom |

phantom of the floppera
Bookmarked 781 weeks ago test run of my diskette organ doing toccata ampamp fuguepeople have made floppy drives sing before but this is my personal take on itfeatures two 3 12quot drives and two 5 14quot drives connected to a pic18f14k50 microcontroller it interfaces to any midi source via midi over usb straight midi would also be possible with an additional small circuit and some minor firmware changes this initial version can respond to all 128 midi notes and pitch bends - 2 semitonesas it can produce only four simultaneous notes and each drive has a different range and tonal characteristics best results are obtained by arranging compositions by hand however it features two modes of operation: in one mode midi channels 1 through 4 are played directly on floppy drives 1 through 4 in the other mode all 16 midi channels are read and notes are quotintelligentlyquot divvied out on a first-come first-serve basis quotnote stealingquot ensures that melody lines sound but chords are often cut short one or the other produces acceptable results for many unmodified midi files straight out of your favorite media playeri apologize for the poor video quality : |
