Subject: [alt-beam] Re: Tilden on TV...


You have a good point. I had gone out to produce my own SMD Bicore tiles
from which to work my own wizardry from. And it's not easy. Even though I
have the tiles now, many things become apparent about the design. Since
they don't come pre-assembled, assebmly is time consuming, especially on
the SMD level. (shaky hands!) And my boards are a pain to cut out. Right
now however I've built a rather clever stryder type robot that has some
pretty nifty skills at walking. I've noted a trick in the orientation of
the legs that gives it rather high lege clearence and at times virtually
no leg dragging. Right now I'm using it as a base to design some sort of
BRAIN using a 2dof head and some of my early, fancy, and yet untested
circuits that I devised to control and interpret signals from a depth
perceving head. More on that to come as the project continues.

IN general however, Mark T. has a great advantage with the pre-assembled
boards. However, for any individual, that must be ludicrously expensive.
