Hi guys,
My bluetooth R/C car, mentioned in the past, currently uses two servos as mechanical method of switching polarity and controlling speed on the car. I use a servo controller rather than a microprocessor. Obviously, my method isn't the ideal (though it works very well, except that I can easily burn out the rheostat that I'm using).
I've found this piece of hardware:

It's got the standard 3wire servo connector on it. Does this mean I can hook it up to my servo controller (Mini SSC II) and control it with byte values (0 - 255)?

yes, I've used a unidirectional ESC, but this should be the same thing. It simply works on a servo signal and translates it into an output. The said "pushbutton" seems like that's what centers it so if you have a 128 (from your 0-255 range) (aka, ~1.5ms pulse width) output and you push the button that'll designate that the center, or if you have 6 it'll do the same, though leaving very little room for one direction. I would assume it saturates at the other end as well. the one I have is already pre-configured to have stop at one end and ramps up from there. Well, hope this helps.

Thanks, that pretty much verifies what I thought. Crazy though, that it costs more than the servo controller did.
I'd assume that it's plenty fast too *shrug*.
Not going to buy it yet, but it's good to keep such in my bookmarks.

just a note, http://www.servocity.com and http://www.dimensionengineering.com also have similar products (for controlling DC motors with servo signals)
