small is beautiful

Peter Rand

I have gone thru the parallax routines with the educational unit. Now I would like to incorporate movement into a piece of art. I would like the dedicated combination of micrcontroller, servocontroller, battery power supply and one servo motor to be as small as possible. Please tell me what best I need to purchase to do this. Thanks.

If you have the stamp and a way to program it all you need is the servo (but one powerful enough to do what you want) and a battery. For power to weight/size lithium are a good choice.

...don't I need a servocontroller board as well? - and is there a small single board that takes both stamp and servocontroller?

If you are talking about one servo (or even five) you don't need a servo controller to move the servos. This will depend on what else you want to do at the same time but your premise was ONE servo and a battery.

To elaborate ...
The Stamp can directly control one or more servos using the PULSOUT statement. The servos require that the control pulse (1-2ms) be repeated about every 20ms. If you want the Stamp to do more than just control the servos, there's not much time left in this 20ms cycle once you get to more than 3 to 5 servos. External servo controllers are used to remove this "burden" from the Stamp so that it can do other control functions when there are many servos.

Thanks Mike - can you point me to the exact Parallax product I need to give me the smallest stamp with board that has usb and battery connections? Are there smaller smilar products? Many thanks.
