If you mount on an axis paralell to the earth's axis, you can point your
panel at the sun and rotate at 15 degrees per hour and your panel will stay
at the optimum angle to the sun.
I have a simple scematic of how you might do it at

Has anybody other low tech ways of tracking the sun?

Well, close enough for cooking and flat panels but if you're
using a concentrator you might need more accuracy than that.

Then again, in any industrialized country cheap parts can be
found to put together a tracker that will always point at the
sun. Perhaps using 12V DC geared motors like those used to move
car windows or wipers.

 I have a new tracking method at http://solarcooking.wikia.com/wiki/Tracking
which should be easy to modify for the real world. It is the one with the
float in a tank of water. It is currently just a concept. (I have not done
it).
The tracking solar acumulating barbecue is also just a concept.
The latest on it is this video on setting up your parabolic dish like the
heliostat so that your focus remains stationary all day.

I will not be able to do this till late march so get there before me!
The parabolic dish that you need can be figured out like i did with my
little figurines in the video and it can then be made with a "mechanical
mathematician" to guide you. I just downloaded different size parabolic
curves from the net and used them to decide on a figurine height.
And from that, I could gestimate sizes for the real dish.
 I have other videos to explain the mechanical mathematician.
All this is genuine. Be the first to put the pieces together and you will
(seriously) have a  place in solar history!
Enough talk, if it is sunny outside, start your tracking solar accumulating
barbecue project RIGHT NOW!
