Hello all, long time since my last post on here.
I've been doing some research over the past few days to try and work out exactly what I need, although I'm having trouble forming a definitive strategy. Here goes:
I'm working on an installation at the moment that uses 6 continuous rotation hobby servos (http://www.oomlout.co.uk/servo-continuous-rotation-p-235.html) and 3 micro servos (http://www.oomlout.co.uk/servo-micro-p-195.html) Rather naively, I had been using my Duemillanove's 5v pin and was getting away with it, although I know now that this isn't a viable method:
I was thinking about picking up something like this: http://www.coolcomponents.co.uk/catalog/breadboard-power-supply-5v33v-p-806.html Would it be sufficient? I'm trying avoiding changing my setup too much and just focusing on getting enough power for all of the servos (avoiding additional shields etc.)
I'd be very appreciative of any advice/input people might be able to give. I just wish I'd read about how much power these things need sooner!
P.S. I'm fairly certain this is a power related issue. If it's not, here are the symptoms: the servos move erratically when I attach more than a couple, although it's not always instant, as you can see in the video. I've gotten away with it for prolonged periods before but sometimes they start juddering as soon as the Arduino gets power. I've even had a couple of kernel panics recently :~
