Arduino solenoid concert

[jay] reminded us of this old video of solenoids banging rhythms on furniture and household objects. There’s no schematic, but in the video it looks like an Arduino drives a bunch of solenoids through relays. The PC interface is run on Pure Data, an open source programming environment for audio, video, and graphic processing. Thanks [Jay].

  1. This is quite the epic noise maker. What be even more epic would be if some one cut a bunch of bamboo rods so they play notes when struck with solenoids.

  2. Hurray for duct tape! this is a permanent set-up, no? :)
    Today I saw an actuator-operated guitar. but that was probably pneumatic.
    Try putting the solenoid in the center of the window and then resonate.

  3. I have been attempting a similar project, but in the form of a one man band. I have had some problems finding affordable solenoids as powerful as those in the video. Any suggestions?

  4. sol, go to digikey 527-1000-ND can be had for $16 in more than 25, or $15 on mouser for more than 10 units.
    I’m sure you could find used surplus for much cheaper elsewhere.

  5. remember the tunnel dwellers who lived below the city from beauty and the beast (tv series where beast had lion face). they used to bang on pipes to communicate with each other. imagine if they had a system like this. they would have been banging out some sewer techno and the lion would have danced!

  6. This guys neighbors probably want to inflict bodily harm with him pounding on the pipes like that. I wonder how long it took before someone knocked on his door…

  7. Why wouldn’t he have used Triacs instead of relays to control the solenoids? Seems to me that it would give more resolution and they only require 5v @ 40ma to trigger.

  8. yoyo.. thanks for all the comments. there is indeed no good reason to use relays instead of triacs or the like. i just had the relay board ready and at hand. next version will be driven by mosfets with probably even velocity control (need some more testing).
