Thread: 'Supermodified' Servos

  1. #1

    Default 'Supermodified' Servos

    "Hack your servo v3.00: Get full PID position and speed control from your servo"

    Sure looks great in the video: http://www.youtube.com/watch?v=8jajnIBX2cU

    But little or no followup info: http://code.google.com/p/zosupermodified

    Too good to be true?

    Check out the "Downloads" tab, and specifically the data sheet. I only glanced, but it looks like full docs.

    Good find, John. There is a detailed PDF in "Downloads", it does look like a fair amount of work was done.

    Now please find where to order their servos, kits, or boards...

    I've seen something like that done using the open servo controller. It's a fair amount of work, but you take out the old control board, pot, and rotation stop. You put in a magnet and hall effect sensor to determine rotation and the open servo board to position and give feedback via I2C.

    Now you have a servo that is continuous rotation with position feedback.

    Sparkfun sells open servo boards, but I don’t know if they sell the magnetic sensor.

    I found this: http://www.sparkfun.com/products/9014 but the reviews sound problematic at best.
