Here is another configuration of my camera spinner gadget
http://www.mediavr.com/cameraspinner3.jpg

this has the advantage over previous versions of having a smaller nadir
visual profile -- also looks less visually conspicuous

inside the tube are 3AA batteries and a 9V battery and relay for the
Zap-shot radio release --- which plugs in at the bottom. Or I can plug
in a mechanical switch. By pulling out the top I can change batteries
quickly

This is shot with the camera in a no-parallax position. Which means it
is off-centre in terms of centre of gravity. So it wobbles a bit as it
spins. But I have decided that is not so bad as having parallax issues -
I just need to build up my camera-holding muscles some :-)

Here is a pano I did with it yesterday -- 10.5mm on 5D -- 4 shots mainly
http://www.mediavr.com/citytosurf2006.htm at 3fps
2500th of a second at f4 approx at 320ASA
these direct sun/crowd shots need careful shadow watching -- so that
you arent yourself shadowing some unretouchable area or standing on
someone's shadow
