I've not been on the forum for awhile, so missed this thread...
Motorised heads will NOT speed up the shooting of 'regular' resolution panoramas, simply because the motors needed to turn and and damp a head as quickly as you can by hand would be massive
. In addition, if you want anything approaching accuracy you have to gear down the motors quite a bit and also allow for slowing down the motor before it gets into position etc.
As Eric says, massive numbers of shots for gigapixel panos are another matter. :D
Those of you thinking about LEGO NXT might want to have a look at my blog on the IVRPA site (part 1
, rest of the blog
) where I documented the process of building an aluminium and LEGO head over several months. Note that the Karline Rodeon head mentioned in part one is an older model to the one used by Eric, the new one is much better designed - but once bitten, twice shy...
One wonderful thing about NXT is that you can use a mobile phone as the remote control, including dialogs where the head asks for the number of degrees for each row and column.
P.S. I'll be taking Frankenstein's Panohead to the IVRPA conference in Berkeley
where it will be demonstrated and discussed.
