> I am confused here. are you trying to build a jumbo-rc servo? I can't get my head around this servo-hack thing, how much I try.
I'd like to build a petrol powered wheeled vehicle, have the drive line parts nearly complete and the only thing holding me back is this steering servo issue. The more info I find on the web, the harder it seems to understand (for me, that is). As I understand the schematics in this topic are based on another principle? The contingency plan is to hook the old MAG speed control up to a wiper motor but this is not the ideal approach as it is not self centering, a bull in china shop method. So there we go: I found a description (I think through a post in this forum, but am not able to retrieve the post) that explains hacking the S3003 servo. I get those instructions. Disconnect servo motor, remove mini capacitators and solder new wires from the servo board. Clear. I get the part about the servo potmeter connected to the motor arm for position feedback. Now: - Where do these new wires lead to? Is this the H-Bridge? - Is there a schematic available for a proper H-bridge that can be used to operate a 12 V wiper motor? - How do I hook this all up together? Any information is appreciated. Or easier methods :-) Thanks! Marc
