help for power source..thanks

hi guys,

I am currently doing a project which need to use basic stamp to
drive a few servo motors. As I am quite new in this field, I hope
that my enquiries can be answered here.

I am currently working on 4 basic stamp2 SX which need to be
connected by totally 12 servo motors. Since only simply motion is
desired, thus for starting, I will only connect 3 servo motors to
each basic stamp, or may be I may connect 4 servo motors to one
stamp. The question is, is this possible ?

I would like to use 4 AAsize 1.5v battery, can I use only 4 AAsize
1.5v battery to power up 4 basic stamps2SX and 12 servo motors ? Or
is there any other better way to connect it to the power source ?

Other than that, I would like to know do I need to add any resistor
or capacitor or fuse to my circuit to prevent short circuit ? If
yes, what is the exact component I needed ?

It may sound silly to ask all this, but I really need to know as I
am really new and I need a proper guide from someone who is
experienced. I am using FUTABA S3003 servo motor.

Thanks for your patience to spend some time to read on this. Thanks
in advanced. Have a nice day.




Francis

    Don't know to much about stamps (so what am i doing here [noparse]:)[/noparse] but you
    have three wires to the servo (signal, ground and power). There is no
    need to run the power over the stamp. You can get the power directly
    from a powersource like a battery. Just don't forget to connect the
    ground of the battery to the ground of the oopic.

    I don't think 4 AA batteries will not run all that at once. Do all 12 servos
    operate at the same time? It will help to put a large cap, say 2200 uF or
    greater across the servos. Try it and see is the easist way to find out.

    Are you using a servo controller? If the Stamps running the servos need to
    do much else, you should loook at the PWMPAL or similar servo controller.
