Subject: [alt-beam] Re: please HELP....5 motor walker
Huh, well, RC servo's really, reall, cause a headache. I'm telling you, I
tried what your doing before. My idea was to first use a ton of .1uf caps.
Everywhere, This helps a little bit. Also use a couple Big caps across your
power rails. say 220uf something like that. I don't understand how you have
your 2 power sources strung up, but it may be causing a problem. Although,
I'm not sure how you would run everything off the same power with five
servos.
