    Default Any idea how this guy made these skeletons dance to the music?

    I stumbled upon this video of spooky scary skeletons and they're using what looks like some skeletons that I've seen at either home depot or spirit or somewhere but if you notice they're controlling different components of the animatronic in the sequence...

    I'm really interested in where to start reading about how to do this. Heck, maybe whoever created this is on this forum.

    Cheers,
    -Lance

    I don't know his name but he is on the forum, check in the showing off forum, he posted the video there. You can control devices like that with Vixen

    Excellent! No clues from his website. Off the top of my head:

    Servo control thoughts:
    • An LOR ServoDog is built to drive servos.
    • Analog servos (I think) are controlled by Pulse Width Modulation (PWM). Dumb RGB's are controlled by PWM. I do not know if a single "standard" LED dimmer channel from an RGB controller board will drive a servo or not. Voltages and PWM frequencies may be issues.
    • Either way, servos would just be another channel to be sequenced the way we currently do.


    Pneumatic control thoughts:
    • 5v, 12v, 110v Pneumatic solenoid valves are available and can be easily driven by an RBG or AC controller.
    • Usually full on, full off. Usually not half movements.


    Jaw movements:
    • Jaw movements are likely servos, but possibly (not likely) pneumatic. Jaw movements are not always full swing.
    • A picotalk controller take stereo sound input and passes it thru to amp'ed speakers. Along the way, it converts a channel of sound to servo movements. Louder sound = larger movement. Not the best but not bad. You can also manually produce a sound file with Audacity that has one channel for servo movement and one channel for real sound. This is similar to the sequencing we currently do.
    • I doubt he has a separate feed thru a picotalk and his movements look too good.


    Body movements:
    • Body movement seems to be cyclic and at a fixed speed. That argues against precise control. If he had precise control, he would use it. He didn't. Therefore, he doesn't (yes, I used a fallacy in logic).
    • There are some small jerky sub motions (arms) that might be loose joints but I doubt they are separate control channels.
    • I think servos would need to be large and expensive. They would give precise control but that was not shown.
    • Could be pneumatic pistons but the action seems rhythmic. Pneumatic can also handle heavy articulations. Also pneumatics would allow more precise control (not shown).
    • I suspect a windshield wiper motor(s) with a bell crank arm. It would handle heavy articulations and give smooth steady movement. It could be controlled by a 12v DC channel (hmm, amps may be a problem ...)

    It would appear that this fellow is re selling Jim's San Devices Controllers .

    On his home page there is a big discrepancy .

    He states this in one breath >

    Seven years ago I saw an awesome show near Cleveland, OH and asked my wife if I could make our lights dance to the music. I spent thousands of dollars and thousands of hours programming my shows .

    Then this in another >

    For more than eight years, lightrageous engineers have supplied customers with custom sequences specifically designed to the customer needs

    lmao
