hi, thanks for addressing this question. And I invite
participate, or get in touch with me for a phone conversation, and discuss
simple steps that can be taken IMHO within 50-100 USD. I suggest we adopt
AMSAT friendly tips:
additional interface to PC, any kind)
(cool idea, but only as concept)
<--- what do you think of this
style? Looks simple enough.
But I have only done a simple google search here. Any other projects worth
investigating? Focus on the "mount" only now.

Feel free to ask around. A few on the list have driven unusual devices
to get antennas moved.
How does a project get into the hands of people who will actually do
it? A one off I can do for you in my basement. Probably with parts
from radio shack, a grinder and a few hand tools.. A reproducible
project 10 years from now? Hardly likely.
I submit to you that irrespective of the metalwork this is a simple
project as you propose, however it must be reproducible. With a
student copy of SolidWorks, a circular saw, drill and the Arduino IDE
it could be prototyped by two people in a weekend. Refining it so that
a relatively new ham with a smidgin of technical ability could do it
might take a little longer. These days with the internet and cad, the
real issue is the tooling. How do you design/layout such that it can
be done with snips/file/saw/fill in the blunt instrument here..
73 es have fun..

I hope it is evident, I am not focusing on the
controller/microcontroller/computer interface/az-el controller/etc. The
issue is how cheaply can an antenna be mounted on
a kingpost somewhere
surface, with a view towards the sky, and how
conveniently can that
motorized, with a sensor to give feedback to the
electronics, seem to be, (apologises to EE friends) a dime a dozen,
if made in hundreds, but the key drawback of any
design is the
and electromechanical (can we use, mechatronics)
system that serves as
actuators. I am not referring to a hand held
antenna assembly, but
something that we can all use in cold/hot weather
and that can be put
together by one / two persons on an average post.
Comments welcome, I think the future holds bright for amsats and edu
