ganito nalang.. humahaba na ang usapan ah  DC motors with worm gears CAN hond position with NO POWER sent to motor.. its because sa pagkakagawa ng gears (wormgear).. di pwede i-rotate WITHOUT gibain ang gear teeth... why not try SERVOMOTORS with higher torque.. yan pwede marotate ang shaft from the "outside" but an electronic brake can be used to STOP the motor/shaft in place.. |

^ merong mga design sis na SERVO ang gamit. pero kapag naka-tigil nagkakaroon ng noise sa image ng camera kaya linalagyan pa rin ng separate brakes. or pinupuno ng choke. |

Thanks sa mga suggestions. Ano ba ang mas mura yung Wind Shield Wiper or yung Servo na may mataas na torque. Actually kailangan ko rin ng controller so maganda yung motor at controller ay ma-consider ko. Sa mechanical madali namang pagkabitkabitin ang bakal using screw and bolts. Paano ba i-interface ang joystick sa DC motor or Servo. Ganito kasi naiisip kong magandang gawin.  |

Pwede mong ma-control ang speed at kapag di mo ginalaw ang joystick eh naka-stop sya sa any position.   |

depende yan sa "driver" mo.. kung unhacked servo ka, kelangan mo ng 1-2mS (50-60Hz)signal to control position...

maingay yung sa wiper motor dahil mabilis sya, kung idridrive sya sa mas mababa na voltage mababawasan yung noise, yung power window motor mabagal yon at hindi rin maingay  |

Paano ba i-interface ang joystick sa DC motor or Servo. Ganito kasi naiisip kong magandang gawin. typical circuit na gamit sa power window ,sa ganitong configuration kapag walang nakaenergize na isang relay nakabreak yung motor  kung kelangan naman ng accurate positioning, kelangan mo ng servo controller meron kang sensor para madetect yung position ng actuator example nito itong MC33030 based servo motor controller potentiometer ang gamit sa pagdetect ng position at potentiometer din ang pang control ng position na dapat nyang kalagyan:  ito naman yung cheaper version using opamp as comparator  |

isa pang naalala ko ay yung joystick na ginagamit sa video arcade machine, meron yong apat na spdt micro switch para sa up/down/left/right pwede yung ganitong connection:  |

^ pwede rin 'yung DPDT na ON/OFF switch na may off position. |

kung ganyan kelangan mo ng PWM driver katulad nito:  more info hereang di ko lang sure kung meron kang makukuhanan ng linear joystick |
