Detail Veiwing of the Sun

Looking at some old astronomy books they had several descriptions of making
your own equipment for looking at the sun in detail, instead of using very
expensive filters.
As anyone have any ideas or web sites that would describe such methods.
Of course I would be using video camera instead of the naked eye for
viewing.
I no longer have these books around but there must be sum URL sites with
this information.

Thanks Craig

The simplest way, is projection. Given the low price now of 'good' Solar
filter materials (Baader astro-solar film), the tendency for cheaper
telescopes to have plastic lenses in some parts of the optical system, and
the move towards the 'SCT' as the commonest telescope (which because of it's
sealed design, and corrector, is not suitable for this application), it has
perhaps fallen 'out of favour' for use with telescopes.
Using a mirror, covered except for a small point, and projecting onto a
white card, is easy/cheap/safe.
